Smack: fuse mount hang fix
The d_instantiate hook for Smack can hang on the root inode of a
filesystem if the file system code has not really done all the set-up.
Fuse is known to encounter this problem.
This change detects an attempt to instantiate a root inode and addresses
it early in the processing, before any attempt is made to do something
that might hang.

x86, fpu: fix CONFIG_PREEMPT=y corruption of application's FPU stack
Jürgen Mell reported an FPU state corruption bug under CONFIG_PREEMPT,
and bisected it to commit
v2.6.19-1363-gacc2076, "i386: add sleazy FPU
optimization".
Add tsk_used_math() checks to prevent calling math_state_restore()
which can sleep in the case of !tsk_used_math(). This prevents
making a blocking call in __switch_to().
Apparently "fpu_counter > 5" check is not enough, as in some signal handling
and fork/exec scenarios, fpu_counter > 5 and !tsk_used_math() is possible.
It's a side effect though. This is the failing scenario:
process 'A' in save_i387_ia32() just after clear_used_math()
Got an interrupt and pre-empted out.
At the next context switch to process 'A' again, kernel tries to restore
the math state proactively and sees a fpu_counter > 0 and !tsk_used_math()
This results in init_fpu() during the __switch_to()'s math_state_restore()
And resulting in fpu corruption which will be saved/restored
(save_i387_fxsave and restore_i387_fxsave) during the remaining
part of the signal handling after the context switch.

x86: fix Xorg crash with xf86MapVidMem error
Clarify the usage of mtrr_lookup() in PAT code, and to make PAT code
resilient to mtrr lookup problems.
Specifically, pat_x_mtrr_type() is restructured to highlight, under what
conditions we look for mtrr hint. pat_x_mtrr_type() uses a default type
when there are any errors in mtrr lookup (still maintaining the pat
consistency). And, reserve_memtype() highlights its usage ot mtrr_lookup
for request type of '-1' and also defaults in a sane way on any mtrr
lookup failure.
pat.c looks at mtrr type of a range to get a hint on what mapping type
to request when user/API: (1) hasn't specified any type (/dev/mem
mapping) and we do not want to take performance hit by always mapping
UC_MINUS. This will be the case for /dev/mem mappings used to map BIOS
area or ACPI region which are WB'able. In this case, as long as MTRR is
not WB, PAT will request UC_MINUS for such mappings.
(2) user/API requests WB mapping while in reality MTRR may have UC or
WC. In this case, PAT can map as WB (without checking MTRR) and still
effective type will be UC or WC. But, a subsequent request to map same
region as UC or WC may fail, as the region will get trackked as WB in
PAT list. Looking at MTRR hint helps us to track based on effective type
rather than what user requested. Again, here mtrr_lookup is only used as
hint and we fallback to WB mapping (as requested by user) as default.
In both cases, after using the mtrr hint, we still go through the
memtype list to make sure there are no inconsistencies among multiple
users.

x86: enable preemption in delay
The RT team has been searching for a nasty latency. This latency shows
up out of the blue and has been seen to be as big as 5ms!
Using ftrace I found the cause of the latency.
pcscd-2995 3dNh1 52360300us : irq_exit (smp_apic_timer_interrupt)
pcscd-2995 3dN.2 52360301us : idle_cpu (irq_exit)
pcscd-2995 3dN.2 52360301us : rcu_irq_exit (irq_exit)
pcscd-2995 3dN.1 52360771us : smp_apic_timer_interrupt (apic_timer_interrupt
)
pcscd-2995 3dN.1 52360771us : exit_idle (smp_apic_timer_interrupt)
Here's an example of a 400 us latency. pcscd took a timer interrupt and
returned with "need resched" enabled, but did not reschedule until after
the next interrupt came in at 52360771us 400us later!
At first I thought we somehow missed a preemption check in entry.S. But
I also noticed that this always seemed to happen during a __delay call.
pcscd-2995 3dN.2 52360836us : rcu_irq_exit (irq_exit)
pcscd-2995 3.N.. 52361265us : preempt_schedule (__delay)
Looking at the x86 delay, I found my problem.
In git commit
35d5d08a085c56f153458c3f5d8ce24123617faf, Andrew Morton
placed preempt_disable around the entire delay due to TSC's not working
nicely on SMP. Unfortunately for those that care about latencies this
is devastating! Especially when we have callers to mdelay(8).
Here I enable preemption during the loop and account for anytime the task
migrates to a new CPU. The delay asked for may be extended a bit by
the migration, but delay only guarantees that it will delay for that minimum
time. Delaying longer should not be an issue.
[
Thanks to Thomas Gleixner for spotting that cpu wasn't updated,
and to place the rep_nop between preempt_enabled/disable.

- Make ata_sff_altstatus private so nobody uses it by mistake
- Drop the 400nS delay from it
Add
ata_sff_irq_status - encapsulates the IRQ check logic
This function keeps the existing behaviour for altstatus using devices. I
actually suspect the logic was wrong before the changes but -rc isn't the
time to play with that
ata_sff_sync - ensure writes hit the device
Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so
that we can fix the nasty delay this causes on most systems.
- ata_sff_pause - 400nS delay
Ensure the command hit the device and delay 400nS
- ata_sff_dma_pause
Ensure the I/O hit the device and enforce an HDMA1:0 transition delay.
Requires altstatus register exists, BUG if not so we don't risk
corruption in MWDMA modes. (UDMA the checksum will save your backside in
theory)
The only other complication then is devices with their own handlers.
rb532 can use dma_pause but scc needs to access its own altstatus
register for internal errata workarounds so directly call the drivers own
altstatus function.

This change plus a follow up from the Blackfin guys is needed to avoid
blackfin losing features in this release.

[ALSA] hda - Fix resume of auto-config mode with Realtek codecs
The auto-config mode of Realtek ALC codecs has a bug since 2.6.25
that it cannot resume properly. The problem was the wrong assignment
of init_hook that overrides the whole initialization.

PNP: mark resources that conflict with PCI devices "disabled"
Both the PNP/PCI conflict detection quirk and the PNP system
driver must use the same mechanism to mark resources as disabled.
I think it's best to keep the resource and to keep the type bit
(IORESOURCE_MEM, etc), so that we match the list from firmware
as closely as possible.

sh: fix miscompilation of ip_fast_csum with gcc >= 4.3
As noted by Matthew Wilcox:
Kyle McMartin just tracked down a bug on parisc to a missing
"memory" clobber in the inline assembly implementation of
ip_fast_csum. The FRV, SH and Xtensa ports are also missing a
memory clobber, so I thought it would be polite to let you know.
The bug manifests as dropped network packets (obviously they have
the wrong checksum). It started appearing for parisc with GCC 4.3.
The GCC manual says:
If your assembler instructions access memory in an unpredictable
fashion, add `memory' to the list of clobbered registers. This
will cause GCC to not keep memory values cached in registers
across the assembler instruction and not optimize stores or loads
to that memory.
I see that FRV has a 400 byte memory output which may prevent this
problem from appearing, but SH and Xtensa have nothing to prevent
this bug. Hope this saves you a few days of debugging.

PCI: fix rpadlpar pci hotplug driver sysfs usage
When Greg "fixed" the sysfs usage of that driver a while back, he seem
to have introduced a bug where the quotes are added around the name of
our specific sysfs files, thus breaking the user space tool.
This fixes it. Tested DLPAR operations on a POWER6 machine successfully.

[libata] sata_fsl: Fix broken driver, add port multiplier (PMP) support
The following commit (
4c9bf4e799ce06a7378f1196587084802a414c03):
libata: replace tf_read with qc_fill_rtf for non-SFF drivers
Broke the sata_fsl.c driver in 2.6.26-rc. I know the following patch fixes
the issue, it clearly also adds port multipler support. The current
2.6.26-rc driver is broken.
On boot with debug enabled we get something like (w/o this patch):
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
spurious interrupt!!, CC = 0x1
interrupt status 0x1
xx_scr_read, reg_in = 1
.. continues for ever.
This change fixes this as a side effect of adding port multiplier support.

ata_piix: fix macbook ich8m problems
ICH8M on macbooks are peculiar in that some of them lock up when the
second port is enabled, some return bogus values on SIDPR access while
yet others hang on SIDPR access. Also, the ich8m_apple_sata entry was
wrongly added below generic ich8m entry making it virtually useless.
This patch works around macbook ich8m problems by
* moving ich8m_apple_sata entry above generic ich8m entry
* dropping PIIX_FLAG_SIDPR from ich8m_apple_sata
* adding subsystem 106b:00a1 as ich8m_apple_sata
