2f5bf1f2d0 ocfs2_dlm: Check for migrateable lockres in dlm_empty_lockres()
In dlm_migrate_lockres(), we check upfront whether the lockres is a
candidate for migration. This patch encapsulates that code in a separate
function so that dlm_empty_lockres() can also use it during umount. This
patch addresses the umount process spinning problem.

78062cb2e5 ocfs2_dlm: Fix lockres ref counting bug
During umount, the umount thread migrates the lockres' and the dlm_thread
frees the empty lockres'. Due to a race, the reference counting on the
lockres goes awry leading to extra puts.

948ac6d71c [PATCH] clocksource: Fix thinko in watchdog selection
The watchdog implementation excludes low res / non continuous
clocksources from being selected as a watchdog reference
unintentionally.

Allow using jiffies/PIT as a watchdog reference as long as no better
clocksource is available. This is necessary to detect TSC breakage on
systems, which have no pmtimer/hpet.

The main goal of the initial patch (preventing to switch to highres/nohz
when no reliable fallback clocksource is available) is still guaranteed
by the checks in clocksource_watchdog().

9501b6cf55 [PATCH] dynticks: fix hrtimer rounding error in next_timer_interrupt
The rework of next_timer_interrupt() fixed the timer wheel bugs, but
invented a rounding error versus the next hrtimer event. This is caused
by the conversion of the hrtimer internal representation to relative
jiffies.

This causes bug #8100:
http://bugzilla.kernel.org/show_bug.cgi?id=8100

next_timer_interrupt() returns "now" in such a case and causes the code
in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is
bogus as no timer is due for expiry. This results in an endless context
switching between idle and ksoftirqd until a timer is due for expiry.

Modify the hrtimer evaluation so that, it returns now + 1, when the
conversion results in a delta < 1 jiffie.

It's confirmed to resolve bug #8100

53698d2537 [ARM] 4278/1: configure pxa27x I2C SCL as "input"
It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

d9a5c0a4e0 [PATCH] i386: Prevent early access to TSC to avoid crash on TSCless systems
commit f9690982b8 removed the check for
cpu_khz from sched_clock(), which prevented early access to the TSC by
non obvious magic.

This is harmless as long as the CPU has a TSC. On TSCless systems this
results in an illegal instruction trap.

Replace tsc_disabled and tsc_unstable by tsc_enabled, which is only set
when the tsc is available and not unstable.

f33bc55c47 [PATCH] x86_64: avoid sending LOCAL_TIMER_VECTOR IPI to itself
Ray Lee reported, that on an UP kernel with "noapic" command line option
set, the box locks hard during boot.

Adding some debug printks revealed, that the last action on the box
before stalling was "Send IPI" - a debug printk which was put into
smp_send_timer_broadcast_ipi().

It seems that send_IPI_mask(mask, LOCAL_TIMER_VECTOR) fails when
"noapic" is set on the command line on an UP kernel.

Aside of that it does not make much sense to trigger an interrupt
instead of calling the function directly on the CPU which gets the
PIT/HPET interrupt in case of broadcasting.

6ea65ff79c [PATCH] i386: clear segment register padding in core dumps
The segment register slots in struct pt_regs are padded to 32 bits.
Some of these are stored with instructions like "pushl %es", which
leaves the high 16 bits as they were.  So the high bits of these
fields in struct pt_regs contain kernel stack garbage.  These bits are
ignored by everything and never leak to user space, except in core
dumps.  The user struct pt_regs is always at the base of the thread's
kernel stack and so it seems unlikely the information that leaks from
here is ever worthwhile so as to be a security concern, but I'm not
sure about that.  It has been this way for ages; userland consumers of
core dumps all mask off these high bits themselves.  So it is not urgent.

This change masks off the padding bits of the segment register slots
in core dumps.  ptrace already masks off these high bits, so this
makes the values in core dumps consistent with what ptrace would
report just before the process died.

As I read the processor manuals, the cs and ss values will always be
padded with zero bits rather than stack garbage.  But unlike "pushl %es",
this is not simple to test with a userland program.  So I added the two
instructions rather than wonder if they are really never necessary.

I think that x86_64 does not have this problem (for either 32-bit or
64-bit processes).  It only uses "mov" instructions from segment
registers, which zero-extend.

Fix the /proc/pid/stat representation of executable boundaries.  It should
show the bounds of the executable, but instead shows the bounds of the

Before the patch is applied, the bug can be seen by examining, say, inetd:

	# ps | grep inetd

 	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0

The code boundaries are 3233480704 to 3233523592, which are:

	(gdb) p/x 3233480704
	$1 = 0xc0bb0000
	(gdb) p/x 3233523592
	$2 = 0xc0bba788

Which corresponds to this line in the maps file:

	c0bb0000-c0bba788 r-xs 00000000 00:0b 14582157  /lib/ld-uClibc-0.9.28.so

Which is wrong.  After the patch is applied, the maps file is pretty much
identical (there's some minor shuffling of the location of some of the
anonymous VMAs), but the stat file is now:

	# cat /proc/610/stat
	610 (inetd) S 1 610 610 0 -1 256 0 0 0 0 0 7 0 0 18 0 1 0 94392000722
	950272 0 4294967295 3276111872 3276141668 3274440352 3274439976
	3273467584 0 0 4096 90115 3221712796 0 0 17 0 0 0 0

The code boundaries are then 3276111872 to 3276141668, which are:

	(gdb) p/x 3276111872
	$1 = 0xc3458000
	(gdb) p/x 3276141668
	$2 = 0xc345f464

And these correspond to this line in the maps file instead:

	c3458000-c345f464 r-xs 00000000 00:0b 16384612  /usr/sbin/inetd

Which is now correct.

991b5557f7 [netdrvr] ewrk3: correct card detection bug
Arwin Vosselman pointed out:
> The ewrk3-driver doesn't function with 2.6.16-kernels (used 2.6.16.41 for
> my tests). Cards will never be detected due to this bug.
>
> drivers/net/ewrks3.c:
> Line 417 reads:
>
> if (nicsr == (CSR_TXD | CSR_RXD))
>
> that should be:

> if (nicsr != (CSR_TXD | CSR_RXD))
>
> Comparison with the same line in v2.4 shows why:

6f6881b846 Revert "ucc_geth: returns NETDEV_TX_BUSY when BD ring is full"
This reverts commit 18babd3854.

Michael Barkowski points out that it's wrong, and I agree.  The
patch causes a problem rather than fixes one after another
patch "ucc_geth: Fix BD processing" was applied.  Before that
patch, current packet should be blocked.  However after the patch
current packet is ok and we only need to block next.
