fe69933652 [PATCH] ACPI: repair nvidia early quirk breakage on x86_64
x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET.
However, the quirk works by checking for _not_ finding the HPET...

Delete the nvidia_hpet_detected flag and simply test for
not finding the HPET, which is simple to do now that
acpi_table_parse returns 1 on failure.

618b206f0b [IA64] Proper handling of TLB errors from duplicate itr.d dropins
Jack Steiner noticed that duplicate TLB DTC entries do not cause a
linux panic.  See discussion:

http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html

The current TLB recovery code is recovering from the duplicate itr.d
dropins, masking the underlying problem.  This change modifies
the MCA recovery code to look for the TLB check signature of the
duplicate TLB entry and panic in that case.

44f5c4ced6 [PATCH] uml: arch_prctl should set thread fs
In my previous x86_64 thread fix, I forgot to initialize thread.arch.fs in
arch_prctl.  A process calling arch_prctl to set %fs would lose it on the
next context switch.

It also turns out that you can switch to a process which is in the process
of exiting and which has lost its mm.  In this case, it's worse than
useless to try to call arch_prctl on the host process.

f6dfb4fd7d [PATCH] Add epoll compat_ code to fs/compat.c
IA64 and ARM-OABI are currently using their own version of epoll compat_
code.

An architecture needs epoll_event translation if alignof(u64) in 32 bit
mode is different from alignof(u64) in 64 bit mode.  If an architecture
needs epoll_event translation, it must define struct compat_epoll_event in
asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use
compat_sys_epoll_ctl and compat_sys_epoll_wait.

All 64 bit architecture should use compat_sys_epoll_pwait.

[sfr: restructure and move to fs/compat.c, remove MIPS version
of compat_sys_epoll_pwait, use __put_user_unaligned]

47c51dff4a [PATCH] x86_64: fix 2.6.18 regression - PTRACE_OLDSETOPTIONS should be accepted
Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c
and forced by binary compatibility.  UML/32bit breaks because of this -
since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible
with 2.4 host kernels.

Until 2.6.17 (commit f0f2d6536e) we had:

       default:
                return sys_ptrace(request, pid, addr, data);

Instead here we have:
        case PTRACE_GET_THREAD_AREA:
	case ...:
                return sys_ptrace(request, pid, addr, data);

        default:
                return -EINVAL;

This change was a style change - when a case is added, it must be
explicitly tested this way.  In this case, not enough testing was done.

b53378856f [PATCH] um: mark both consoles as CON_ANYTIME
Since both UML consoles do not use percpu variables, they may be called when
the cpu is still offline, and they may be marked CON_ANYTIME (this is
documented in kernel/printk.c, grep for CON_ANYTIME to find mentions of this).

Works well in testing done with lock debug enabled, should be safe but is not
needed for next release.

This would probably help also stderr_console.c, but this is yet to test.

28c1d39db8 [AVR32] Don't use kmap() in flush_icache_page()
flush_icache_page() can be called from atomic context, so we can't
use kmap(). Use page_address() instead.

a19b4a1405 [AVR32] Fix bogus ti->flags manipulation in debug handler
We should OR in a bitmask, not a bit offset, into ti->flags. This
might fix some strange behaviour when single stepping.

Also, use set_ti_thread_flag() to manipulate the flags to avoid
surprises in the future.

3338368e92 [AVR32] show_trace: Only walk valid stack addresses
Terminate the frame pointer walk if (a) the address is outside the
task's kernel stack or (b) if the frame pointer isn't monotonically
increasing. Without this fix, show_trace() may enter an infinite
loop, walking through random data anywhere in memory.

Since any address within the kernel stack is guaranteed to be valid,
we may eliminate the __get_user() calls as well.
