9899d11f65 ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL
putreg() assumes that the tracee is not running and pt_regs_access() can
safely play with its stack.  However a killed tracee can return from
ptrace_stop() to the low-level asm code and do RESTORE_REST, this means
that debugger can actually read/modify the kernel stack until the tracee
does SAVE_REST again.

set_task_blockstep() can race with SIGKILL too and in some sense this
race is even worse, the very fact the tracee can be woken up breaks the
logic.

As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace()
call, this ensures that nobody can ever wakeup the tracee while the
debugger looks at it.  Not only this fixes the mentioned problems, we
can do some cleanups/simplifications in arch_ptrace() paths.

Probably ptrace_unfreeze_traced() needs more callers, for example it
makes sense to make the tracee killable for oom-killer before
access_process_vm().

While at it, add the comment into may_ptrace_stop() to explain why
ptrace_stop() still can't rely on SIGKILL and signal_pending_state().

9cf2b72b25 arm64: elf: fix core dumping to match what glibc expects
The kernel's internal definition of ELF_NGREG uses struct pt_regs, which
means that we disagree with userspace on the size of coredumps since
glibc correctly uses the user-visible struct user_pt_regs.

This patch fixes our ELF_NGREG definition to use struct user_pt_regs
and introduces our own ELF_CORE_COPY_REGS to convert between the user
and kernel structure definitions.

4ea494b528 MIPS: delay.c: Check BITS_PER_LONG instead of __SIZEOF_LONG__
When building a 32-bit kernel for RBTX4927 with gcc version 4.1.2 20061115
(prerelease) (Ubuntu 4.1.1-21), I get:

arch/mips/lib/delay.c:24:5: warning: "__SIZEOF_LONG__" is not defined

As a consequence, __delay() always uses the 64-bit "dsubu" instruction.

Replace the check for "__SIZEOF_LONG__ == 4" by "BITS_PER_LONG == 32" to
fix this.

__{,n,u}delay declarations match definitions and generic delay.h"]

be3286507d s390/thp: implement pmdp_set_wrprotect()
On s390, an architecture-specific implementation of the function
pmdp_set_wrprotect() is missing and the generic version is currently
being used. The generic version does not flush the tlb as it would be
needed on s390 when modifying an active pmd, which can lead to subtle
tlb errors on s390 when using transparent hugepages.

This patch adds an s390-specific implementation of pmdp_set_wrprotect()
including the missing tlb flush.

021ef050fc x86-32: Start out cr0 clean, disable paging before modifying cr3/4
Patch

  5a5a51db78 x86-32: Start out eflags and cr4 clean

... made x86-32 match x86-64 in that we initialize %eflags and %cr4
from scratch.  This broke OLPC XO-1.5, because the XO enters the
kernel with paging enabled, which the kernel doesn't expect.

Since we no longer support 386 (the source of most of the variability
in %cr0 configuration), we can simply match further x86-64 and
initialize %cr0 to a fixed value -- the one variable part remaining in
%cr0 is for FPU control, but all that is handled later on in
initialization; in particular, configuring %cr0 as if the FPU is
present until proven otherwise is correct and necessary for the probe
to work.

To deal with the XO case sanely, explicitly disable paging in %cr0
before we muck with %cr3, %cr4 or EFER -- those operations are
inherently unsafe with paging enabled.

NOTE: There is still a lot of 386-related junk in head_32.S which we
can and should get rid of, however, this is intended as a minimal fix
whereas the cleanup can be deferred to the next merge window.

bdcc612752 ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls
During the migration to the common clock framework, calls to the
functions omap2xxx_clkt_vps_late_init() were not preserved for
OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and
"curr_prcm_set" to be uninitialised on boot. On reboot, this causes the
following error message to be displayed because the appropriate MPU
clock frequency (derived from sys_ck_rate) cannot be found.

"Could not set MPU rate to 4294MHz"

Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the
OMAP2420 and OMAP2430 clock initialisation code.

9174adbee4 xen: Fix stack corruption in xen_failsafe_callback for 32bit PVOPS guests.
This fixes CVE-2013-0190 / XSA-40

There has been an error on the xen_failsafe_callback path for failed
iret, which causes the stack pointer to be wrong when entering the
iret_exc error path.  This can result in the kernel crashing.

In the classic kernel case, the relevant code looked a little like:

        popl %eax      # Error code from hypervisor
        jz 5f
        addl $16,%esp
        jmp iret_exc   # Hypervisor said iret fault
5:      addl $16,%esp
                       # Hypervisor said segment selector fault

Here, there are two identical addls on either option of a branch which
appears to have been optimised by hoisting it above the jz, and
converting it to an lea, which leaves the flags register unaffected.

In the PVOPS case, the code looks like:

        popl_cfi %eax         # Error from the hypervisor
        lea 16(%esp),%esp     # Add $16 before choosing fault path
        CFI_ADJUST_CFA_OFFSET -16
        jz 5f
        addl $16,%esp         # Incorrectly adjust %esp again
        jmp iret_exc

It is possible unprivileged userspace applications to cause this
behaviour, for example by loading an LDT code selector, then changing
the code selector to be not-present.  At this point, there is a race
condition where it is possible for the hypervisor to return back to
userspace from an interrupt, fault on its own iret, and inject a
failsafe_callback into the kernel.

This bug has been present since the introduction of Xen PVOPS support
in commit 5ead97c84 (xen: Core Xen implementation), in 2.6.23.

6f16f4998f ARM: 7628/1: head.S: map one extra section for the ATAG/DTB area
We currently use a temporary 1MB section aligned to a 1MB boundary for
mapping the provided device tree until the final page table is created.
However, if the device tree happens to cross that 1MB boundary, the end
of it remains unmapped and the kernel crashes when it attempts to access
it.  Given no restriction on the location of that DTB, it could end up
with only a few bytes mapped at the end of a section.

Solve this issue by mapping two consecutive sections.

568dca15aa ARM: 7627/1: Predicate preempt logic on PREEMP_COUNT not PREEMPT alone
Patrik Kluba reports that the preempt count becomes invalid due
to the preempt_enable() call being unbalanced with a
preempt_disable() call in the vfp assembly routines. This happens
because preempt_enable() and preempt_disable() update preempt
counts under PREEMPT_COUNT=y but the vfp assembly routines do so
under PREEMPT=y. In a configuration where PREEMPT=n and
DEBUG_ATOMIC_SLEEP=y, PREEMPT_COUNT=y and so the preempt_enable()
call in VFP_bounce() keeps subtracting from the preempt count
until it goes negative.

Fix this by always using PREEMPT_COUNT to decided when to update
preempt counts in the ARM assembly code.

ed4f20943c s390/time: fix sched_clock() overflow
Converting a 64 Bit TOD format value to nanoseconds means that the value
must be divided by 4.096. In order to achieve that we multiply with 125
and divide by 512.
When used within sched_clock() this triggers an overflow after appr.
417 days. Resulting in a sched_clock() return value that is much smaller
than previously and therefore may cause all sort of weird things in
subsystems that rely on a monotonic sched_clock() behaviour.

To fix this implement a tod_to_ns() helper function which converts TOD
values without overflow and call this function from both places that
open coded the conversion: sched_clock() and kvm_s390_handle_wait().

hook which runs on the cpu itself.  Instead, it should be done in
.cpu_kill which runs on the thread (another cpu) that asks for shutting
down the cpu.  Move imx_enable_cpu(cpu, false) call into .cpu_kill
hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die,
so that we can get a more stable cpu hot-plug operation.

d01723479e ARM: virt: simplify __hyp_stub_install epilog
__hyp_stub_install duplicates quite a bit of safe_svcmode_maskall
by forcing the CPU back to SVC. This is unnecessary, as
safe_svcmode_maskall is called just after.

Furthermore, the way we build SPSR_hyp is buggy as we fail to mask
the interrupts, leading to interesting behaviours on TC2 + UEFI.

The fix is to simply remove this code and rely on safe_svcmode_maskall
to do the right thing.

This check might trigger depending on the kernel config.
Lets make sure that no preemption happens during kvm_guest_enter.
We can enable preemption again after the call to
rcu_virt_note_context_switch returns.

Please note that we continue to run s390 guests with interrupts

a706d965dc perf x86: revert 20b279 - require exclude_guest to use PEBS - kernel side
This patch is brought to you by the letter 'H'.

Commit 20b279 breaks compatiblity with older perf binaries when run with
precise modifier (:p or :pp) by requiring the exclude_guest attribute to be
set. Older binaries default exclude_guest to 0 (ie., wanting guest-based
samples) unless host only profiling is requested (:H modifier). The workaround
for older binaries is to add H to the modifier list (e.g., -e cycles:ppH -
toggles exclude_guest to 1). This was deemed unacceptable by Linus:

https://lkml.org/lkml/2012/12/12/570

Between family in town and the fresh snow in Breckenridge there is no time left
to be working on the proper fix for this over the holidays. In the New Year I
have more pressing problems to resolve -- like some memory leaks in perf which
are proving to be elusive -- although the aforementioned snow is probably why
they are proving to be elusive. Either way I do not have any spare time to work
on this and from the time I have managed to spend on it the solution is more
difficult than just moving to a new exclude_guest flag (does not work) or
flipping the logic to include_guest (which is not as trivial as one would
think).

So, two options: silently force exclude_guest on as suggested by Gleb which
means no impact to older perf binaries or revert the original patch which
caused the breakage.

This patch does the latter -- reverts the original patch that introduced the
regression. The problem can be revisited in the future as time allows.

a6fadf7e67 arm64: mm: introduce present, faulting entries for PAGE_NONE
This is mostly a port of dbf62d5006 ("ARM: mm: introduce L_PTE_VALID
for page table entries") and 26ffd0d43b ("ARM: mm: introduce present,
faulting entries for PAGE_NONE") from ARM, which makes use of present,
faulting page table entries for page table entries mapped as PROT_NONE.

The main difference with this implementation is that we can make use of
the two pte type bits in order to avoid allocating a software bit for
identifying PROT_NONE pages, instead reserving the 10b suffix for these
types of mappings.

This is required to prevent users from accessing such pages via syscalls
such as read/write over a pipe.

This patch is an arm64 version of ce73ec6db4 ("powerpc/vdso: Remove
redundant locking in update_vsyscall_tz()").

Timezone data is not protected, so the sequence counter is not required
to ensure consistency. Furthermore, having multiple paths updating the
counter leads to a race between update_vsyscall and update_vsyscall_tz,
so remove the timezone sequence counting from both the kernel and the

5f79c651e8 arm: mvebu: use global interrupts for GPIOs on Armada XP
The Armada XP GPIO controller has two ways of notifying interrupts:
using global interrupts or using per-CPU interrupts. In an attempt to
use the best available features, the 'marvell,armadaxp-gpio'
compatible string selects a variant of the gpio-mvebu driver that
makes use of the per-CPU interrupts.

Unfortunately, this doesn't work properly in a SMP context, because we
fall into cases where the GPIO interrupt is enabled on CPU X at the
GPIO controller level, but on CPU Y at the interrupt controller
level. It is not yet clear how to fix that easily.

So for 3.8, our approach is to switch to global interrupts for GPIOs,
so that we do not fall into this per-CPU interrupts problem.

This patch therefore fixes GPIO interrupts on Armada XP
platforms. Without this patch, GPIO interrupts simply do not work
reliably, because their proper operation depends on which CPU the code
requesting the interrupt is running.

3b4bc7bccc ALSA: pxa27x: fix ac97 warm reset
This patch fixes some code that implements a work-around to a hardware bug in
the ac97 controller on the pxa27x.  A bug in the controller's warm reset
functionality requires that the mfp used by the controller as the AC97_nRESET
line be temporarily reconfigured as a generic output gpio (AF0) and manually
held high for the duration of the warm reset cycle.  This is what was done in
the original code, but it was broken long ago by commit fb1bf8cd
    ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset())
which changed the mfp to a GPIO input instead of a high output.

The fix requires the ac97 controller to obtain the gpio via gpio_request_one(),
with arguments that configure the gpio as an output initially driven high.

Tested on a palm treo 680 machine.  Reportedly, this broken code only prevents a
warm reset on hardware that lacks a pull-up on the line, which appears to be the
case for me.

420f42ecf4 s390/irq: remove split irq fields from /proc/stat
Now that irq sum accounting for /proc/stat's "intr" line works again we
have the oddity that the sum field (first field) contains only the sum
of the second (external irqs) and third field (I/O interrupts).
The reason for that is that these two fields are already sums of all other
fields. So if we would sum up everything we would count every interrupt
twice.
This is broken since the split interrupt accounting was merged two years
ago: 052ff461c8 "[S390] irq: have detailed
statistics for interrupt types".
To fix this remove the split interrupt fields from /proc/stat's "intr"
line again and only have them in /proc/interrupts.

This restores the old behaviour, seems to be the only sane fix and mimics
a behaviour from other architectures where /proc/interrupts also contains
more than /proc/stat's "intr" line does.

add9bde216 s390/irq: enable irq sum accounting for /proc/stat again
For more than two years, since f2c66cd8ee
"/proc/stat: scalability of irq num per cpu" the output of /proc/stat is
broken.
The first field in the "intr" line should contain the sum of all interrupts,
however since the above mentioned change it is always zero.

The reason for that is that a per cpu irq sum variable had been introduced
which got incremented when calling kstat_incr_irqs_this_cpu(). However
on s390 we directly incremented only the per cpu per irq counter by accessing
the array element via kstat_cpu(smp_processor_id()).irqs[...].
So fix this and use the kstat_incr_irqs_this_cpu() wrapper which increments
both: the per cpu per irq counter and the per cpu irq sum counter.

Since the content of iram.h is not imx specific, move it to
include/linux/platform_data/imx-iram.h instead. This is an intermediate solution
until the i.MX iram allocator is converted to the generic SRAM allocator.

0b3455a71e ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

34360f080c parisc: improve ptrace support for gdb single-step
Various GCC tests use gdb to simulate a multithreaded application. Many of
these tests have been failing on parisc linux.

GCC does this by using gdb to single-step the application, then gdb is used to
call other test specific code. Where this fails is when the application is
stepped into the delay slot of a taken branch. This sets the PSW B bit. When
the test specific code is executed, this usually clears the PSW B bit.
Currently, gdb is not allowed to set the B bit. So, the code falls through what
should be a taken branch.

The attached patch adds the PSW B bit to the set of bits that gdb is allowed to
set. In order to set the B bit, the trace system call must return using an
interrupt restore. The patch also modifies this code to use the saved IAOQ
values when they are saved by a ptrace syscall or interruption.

cabd91c3bb parisc: avoid undefined shift in cnv_float.h
The attached change fixes a float conversion problem found running the
GCC testsuite with GCC configured with --with-arch=2.0.

The actual problem occurs for an exponent value of 63. This is the
maximum exponent value that can be passed. This causes a left shift by
32 in the else hunk of the macro. This causes undefined behavior and the
wrong value is returned for dresultB. The fix is the check "exponent <=
62". If the exponent is 63, dresultB is set to 0. The patch also
optimizes the operation a bit by copying "Sall(sgl_value) <<
SGL_EXP_LENGTH" to val, so that sgl_value is not modified.

The UART controller used in the Armada 370 and Armada XP SoCs is the
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
improper use of the ns16550 can lead to a kernel oops during boot if
a character is sent to the UART before the initialization of the
driver. The DW APB has an extra interrupt that gets raised when
writing to the LCR when busy. This explains why we need to use
dw-apb-uart driver to handle this.

d0e045401f microblaze: Update microblaze defconfigs
The main reason is 0-day testing system which can directly
use these defconfigs for testing.

Enable support for all xilinx drivers which Microblaze
can use and disable dependency on external rootfs.cpio.
There is only one exception which is axi ethernet driver
which still uses NO_IRQ which is not defined for Microblaze.

b881bc469b ARCH: drivers remove __dev* attributes.
This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

d962117687 ARM: nomadik: bump the IRQ numbers again
Bump the IRQ numbers from offset at 1 (right above NO_IRQ)
to 32. This is the painful way to learn that if you're using
SPARSE_IRQ and avoid to define .nr_irqs in your machine,
the first 16 IRQs will be pre-allocated, and the IRQdomain
code (as the VIC core code before it) will then assume
that all IRQ descriptors are pre-allocated, and 16 of them
are - by somebody else. So mapping the IRQs will fail in
irq_create_mapping(). Moving the offset upward rids us of
this problem.

ce73ec6db4 powerpc/vdso: Remove redundant locking in update_vsyscall_tz()
The locking in update_vsyscall_tz() is not only unnecessary because the vdso
code copies the data unproteced in __kernel_gettimeofday() but also
introduces a hard to reproduce race condition between update_vsyscall()
and update_vsyscall_tz(), which causes user space process to loop
forever in vdso code.

The following patch removes the locking from update_vsyscall_tz().

Locking is not only unnecessary because the vdso code copies the data
unprotected in __kernel_gettimeofday() but also erroneous because updating
the tb_update_count is not atomic and introduces a hard to reproduce race
condition between update_vsyscall() and update_vsyscall_tz(), which further
causes user space process to loop forever in vdso code.

The below scenario describes the race condition,
x==0	Boot CPU			other CPU
	proc_P: x==0
	    timer interrupt
		update_vsyscall
x==1		    x++;sync		settimeofday
					    update_vsyscall_tz
x==2						x++;sync
x==3		    sync;x++
						sync;x++
	proc_P: x==3 (loops until x becomes even)

Because the ++ operator would be implemented as three instructions and not
atomic on powerpc.

A similar change was made for x86 in commit 6c260d5863
("x86: vdso: Remove bogus locking in update_vsyscall_tz")

7e7fff8254 ARM: OMAP2/3: PRM: fix bogus OMAP2xxx powerstate return values
On OMAP2xxx chips, the register bitfields for the
PM_PWSTCTRL_*.POWERSTATE and PM_PWSTST_*.LASTSTATEENTERED are
different than those used on OMAP3/4.  The order is reversed.  So, for
example, on OMAP2xxx, 0x0 indicates 'ON'; but on OMAP3/4, 0x0
indicates 'OFF'.  Similarly, on OMAP2xxx, 0x3 indicates 'OFF', but on
OMAP3/4, 0x3 indicates 'ON'.

To fix this, we treat the OMAP3/4 values as the powerdomain API
values, and create new low-level powerdomain functions for the
OMAP2xxx chips which translate between the OMAP2xxx values and the
OMAP3/4 values.

Without this patch, the conversion of the OMAP2xxx PM code to the
functional powerstate code results in a non-booting kernel.

The ETM/ETB drivers for OMAP3, enable the emu_src_ck clock in order
to access the ETM/ETB hardware. The emu_src_ck should enable the EMU
clock domain so that the ETM/ETB hardware is accessible. However,
currently when enabling the emu_src_ck the EMU clock domain is not
being enabled and so the ETM/ETB drivers are failing. Add enable/disable
clock functions to enable the EMU clock domain when enabling the
emu_src_ck.

5ced33bc06 ARM: 7611/1: VIC: fix bug in VIC irqdomain code
The VIC irqdomain code added in commit
07c9249f1f
"ARM: 7554/1: VIC: use irq_domain_add_simple()"

Had two bugs:

1) It didn't call irq_create_mapping() once on each
   valid irq source in the slowpath when registering
   the controller.

2) It passed a -1 as IRQ offset for the DT case, whereas
   0 should be passed as invalid IRQ instead.

f556529589 ARM: 7610/1: versatile: bump IRQ numbers
The Versatile starts to register Linux IRQ numbers from offset 0
which is illegal, since this is NO_IRQ. Bump all hard-coded IRQs
by 32 to get rid of the problem.

62e4d357aa ARM: 7609/1: disable errata work-arounds which access secure registers
In order to support secure and non-secure platforms in multi-platform
kernels, errata work-arounds that access secure only registers need to
be disabled. Make all the errata options that fit in this category
depend on !CONFIG_ARCH_MULTIPLATFORM.

This will effectively remove the errata options as platforms are
converted over to multi-platform.
