1cdab55d8a powerpc: Wire up /proc/vmallocinfo to our ioremap()
This adds the necessary bits and pieces to powerpc implementation of
ioremap to benefit from caller tracking in /proc/vmallocinfo, at least
for ioremap's done after mem init as the older ones aren't tracked.

16962e7ce1 powerpc: Estimate G5 cpufreq transition latency
Setting G5's cpu frequency transition latency to CPUFREQ_ETERNAL stops
ondemand governor from working. I measured the latency using sched_clock
and haven't seen much higher than 11000ns, so I set this to 12000ns for
my configuration. Possibly other configurations will be different?
Ideally the generic code would be able to measure it in case the platform
does not provide it.

But this simple patch at least makes it throttle again.

2d5516cbb9 copy_process: fix CLONE_PARENT && parent_exec_id interaction
CLONE_PARENT can fool the ->self_exec_id/parent_exec_id logic. If we
re-use the old parent, we must also re-use ->parent_exec_id to make
sure exit_notify() sees the right ->xxx_exec_id's when the CLONE_PARENT'ed
task exits.

Also, move down the "p->parent_exec_id = p->self_exec_id" thing, to place
two different cases together.

129f8ae9b1 Revert "[CPUFREQ] Disable sysfs ui for p4-clockmod."
This reverts commit e088e4c9cd.

Removing the sysfs interface for p4-clockmod was flagged as a
regression in bug 12826.

Course of action:
 - Find out the remaining causes of overheating, and fix them
   if possible. ACPI should be doing the right thing automatically.
   If it isn't, we need to fix that.
 - mark p4-clockmod ui as deprecated
 - try again with the removal in six months.

It's not really feasible to printk about the deprecation, because
it needs to happen at all the sysfs entry points, which means adding
a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

0bcd783c1f powerpc: add fsl,fifo-depth property to Freescale SSI device nodes
The Freescale Serial Synchronous Interface (SSI) is an audio device present on
some Freescale SOCs.  Various implementations of the SSI have a different
transmit and receive FIFO depth, but are otherwise identical.  To support
these variations, add a new property fsl,fifo-depth to the SSI node that
specifies the depth of the FIFOs.

Also update the MPC8610 HPCD device tree with this property.

btrfs_tree_locked was being used to make sure a given extent_buffer was
properly locked in a few places.  But, it wasn't correct for UP compiled
kernels.

This switches it to using assert_spin_locked instead, and renames it to
btrfs_assert_tree_locked to better reflect how it was really being used.

Reason for this is that cpu time accounting usually only happens from
interrupt context, but acct_update_integrals gets also called from
process context with interrupts enabled.

So in acct_update_integrals we may end up with the following scenario:

Between reading tsk->stime/tsk->utime and tsk->acct_timexpd an interrupt
happens which updates accouting values.  This causes acct_timexpd to be
greater than the former stime + utime.  The subsequent calculation of

	dtime = cputime_sub(time, tsk->acct_timexpd);

will be negative and the division performed by

	cputime_to_jiffies(dtime)

will generate an exception since the result won't fit into a 32 bit
register.

In order to fix this just always disable interrupts while accessing any
of the accounting values.

1ab082d7cb i2c-mpc: do not allow interruptions when waiting for I2C to complete
The i2c_wait() function is using wait_event_interruptible_timeout() to wait for
the I2C controller to signal that it has completed an I2C bus operation.  If
the process that causes the I2C operation terminated abruptly, the wait will
be interrupted, returning an error.  It is better to let the I2C operation
finished before the process exits.

It is safe to use wait_event_timeout() instead, because the timeout will allow
the process to exit if the I2C bus hangs.  It's also better to allow the
I2C operation to finish, because unacknowledged I2C operations can cause the
I2C bus to hang.

6db6a5f3ae lguest: fix for CONFIG_SPARSE_IRQ=y
Impact: remove lots of lguest boot WARN_ON() when CONFIG_SPARSE_IRQ=y

We now need to call irq_to_desc_alloc_cpu() before
set_irq_chip_and_handler_name(), but we can't do that from init_IRQ (no
kmalloc available).

So do it as we use interrupts instead.  Also means we only alloc for
irqs we use, which was the intent of CONFIG_SPARSE_IRQ anyway.

cbd88c8e6f lguest: fix crash 'unhandled trap 13 at <native_read_msr_safe>'
Impact: fix lguest boot crash on modern Intel machines

The code in early_init_intel does:

	if (c->x86 > 6 || (c->x86 == 6 && c->x86_model >= 0xd)) {
		u64 misc_enable;

		rdmsrl(MSR_IA32_MISC_ENABLE, misc_enable);

And that rdmsr faults (not allowed from non-0 PL).  We can get around
this by mugging the family ID part of the cpuid.  5 seems like a good
number.

Of course, this is a hack (how very lguest!).  We could just indicate
that we don't support MSRs, or implement lguest_rdmst.

4302e5d53b MIPS: compat: Implement is_compat_task.
This is a build fix required after "x86-64: seccomp: fix 32/64 syscall
hole" (commit 5b1017404a).  MIPS doesn't
have the issue that was fixed for x86-64 by that patch.

This also doesn't solve the N32 issue which is that N32 seccomp processes
will be treated as non-compat processes thus only have access to N64
syscalls.

cda56ac29f mmc: fix data timeout for SEND_EXT_CSD
Commit 0d3e0460f3
"MMC: CSD and CID timeout values" inadvertently broke
the timeout for the MMC command SEND_EXT_CSD.

This patch puts it back again.

Depending on the characteristics of the controller,
this bug may prevent the use of MMC cards.

48b3fd14bd powerpc/4xx: update ml507 .dts file to release reference design
This patch updates the Xilinx ML507 device tree to match the released
ML507 powerpc reference design (ml507_ppc440_emb_ref).  This patch is
needed to boot Linux on the ML507 powerpc reference design without
manually generating and tweaking a device tree from the project directory.

73bf1b62f5 x86, pebs: correct qualifier passed to ds_write_config() from ds_request_pebs()
ds_write_config() can write the BTS as well as the PEBS part of
the DS config. ds_request_pebs() passes the wrong qualifier, which
results in the wrong configuration to be written.

9ca0791dca x86, bts: remove bad warning
In case a ptraced task is reaped (while the tracer is still attached),
ds_exit_thread() is called before ptrace_exit(). The latter will
release the bts_tracer and remove the thread's ds_ctx.
The former will WARN() if the context is not NULL.

Oleg Nesterov submitted patches that move ptrace_exit() before
exit_thread() and thus reverse the order of the above calls.

Remove the bad warning. I will add it again when Oleg's changes are in.

c50ff7c042 ALSA: hda - Fix headphone-detect regression with multiple HP jacks
The recent changes over the DAC detection mechanism in patch_sigmatel.c
breaks the HP detection on the machines with multiple HP jacks.
It's basically because of the workaround to support the multi-channel
output.  Since the HP detection is more important feature, disable
the HP-swap workaroud temporarily.

59247eaea5 block: fix missing bio back/front segment size setting in blk_recount_segments()
Commit 1e42807918 introduced a bug where we
don't get front/back segment sizes in the bio in blk_recount_segments().
Fix this by tracking the back bio as well as the front bio in
__blk_recalc_rq_segments(), this also cleans up the interface by getting
rid of the segment size pointer passing.

c9a0c8a684 [WATCHDOG] orion5x_wdt.c: 'ORION5X_TCLK' undeclared
orion5x_wdt no longer compiled after the changes in commit
ebe35aff88 ("Orion: prepare for
runtime-determined timer tick rate").

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime
detection. The quick fix is to add the define in the watchdog driver.
The fix is not correct for all supported orion5x platforms, but since
the supported platforms right now are 133 Mhz and 166 Mhz, it won't
be _that_ far off. ;-) A fix that uses the runtime-determined timer
tick rate will be applied later.
