ARM: 7308/1: vfp: flush thread hwstate before copying ptrace registers
If we are context switched whilst copying into a thread's
vfp_hard_struct then the partial copy may be corrupted by the VFP
context switching code (see "ARM: vfp: flush thread hwstate before
restoring context from sigframe").
This patch updates the ptrace VFP set code so that the thread state is
flushed before the copy, therefore disabling VFP and preventing
corruption from occurring.

ARM: 7307/1: vfp: fix ptrace regset modification race
In a preemptible kernel, vfp_set() can be preempted, causing the
hardware VFP context to be switched while the thread vfp state is
being read and modified. This leads to a race condition which can
cause the thread vfp state to become corrupted if lazy VFP context
save occurs due to preemption in between the time thread->vfpstate
is read and the time the modified state is written back.
This may occur if preemption occurs during the execution of a
ptrace() call which modifies the VFP register state of a thread.
Such instances should be very rare in most realistic scenarios --
none has been reported, so far as I am aware. Only uniprocessor
systems should be affected, since VFP context save is not currently
lazy in SMP kernels.
The problem was introduced by my earlier patch migrating to use
regsets to implement ptrace.
This patch does a vfp_sync_hwstate() before reading
thread->vfpstate, to make sure that the thread's VFP state is not
live in the hardware registers while the registers are modified.
Thanks to Will Deacon for spotting this.

ARM: 7306/1: vfp: flush thread hwstate before restoring context from sigframe
Following execution of a signal handler, we currently restore the VFP
context from the ucontext in the signal frame. This involves copying
from the user stack into the current thread's vfp_hard_struct and then
flushing the new data out to the hardware registers.
This is problematic when using a preemptible kernel because we could be
context switched whilst updating the vfp_hard_struct. If the current
thread has made use of VFP since the last context switch, the VFP
notifier will copy from the hardware registers into the vfp_hard_struct,
overwriting any data that had been partially copied by the signal code.
Disabling preemption across copy_from_user calls is a terrible idea, so
instead we move the VFP thread flush *before* we update the
vfp_hard_struct. Since the flushing is performed lazily, this has the
effect of disabling VFP and clearing the CPU's VFP state pointer,
therefore preventing the thread from being updated with stale data on
the next context switch.

| Reverting it makes my board boot again.
and further debugging reveals:
ioremap: pfn=fffff phys=

ioremap: area

ioremap: found: addr
fef74000 =>
fed73000 =>

Clearly, an area for pfn 0x200, 16K can't ever satisfy a request for pfn
0xfffff. This happens because the changed if statement becomes:
if (0x00200 > 0xfffff ||
0xfffff000 + 0x400 + 0x1000-1 > 0x00200000 + 0x4000-1)
and therefore:
if (0x00200 > 0xfffff ||
0x000003ff > 0x00203fff)
The if condition fails, and so we _believe_ that the SRAM mapping fits
our request. Clearly that's totally bogus.
Moreover, the original premise of the 'fix' patch was wrong:
| The condition checking boundaries of the requested and existing
| mappings didn't take in-page offset into consideration though,
| which lead to obscure and hard to debug problems when requested
| mapping crossed end of the static one.
as the code immediately above this loop does:
size = PAGE_ALIGN(offset + size);
so 'size' already contains the requested offset into the page.
So, revert the broken 'fix'.

ARM: 7298/1: realview: fix mapping of MPCore private memory region
Since commit
0536bdf33faf (ARM: move iotable mappings within
the vmalloc region), the RealView PB11MP cannot boot anymore.
This is caused by the way the mappings are described on this
platform (define replaced by hex values for clarity):
{ /* GIC CPU interface mapping */
.virtual = IO_ADDRESS(0x1F000100),
.pfn = __phys_to_pfn(0x1F000100),
.length = SZ_4K,
.type = MT_DEVICE,
}, { /* GIC distributor mapping */
.virtual = IO_ADDRESS(0x1F001000),
.pfn = __phys_to_pfn(0x1F001000),
.length = SZ_4K,
.type = MT_DEVICE,
}
The first mapping ends up reserving two pages, and clashes with
the second one, which triggers a BUG_ON in vm_area_add_early().
In order to solve this problem, treat the MPCore private memory
region (containing the SCU, the GIC and the TWD) as a single region,
as described in the TRM:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html

MFD: ucb1x00-ts: fix resume failure
If the ucb1x00 touchscreen is resumed while the touchscreen is being
touched, the main thread stops responding. This occurs because two
things happen:
1. When we suspended, we were woken up, and executed the loop.
Finding that the touchscreen was not pressed, we prepare to
schedule for a maximum timeout, before being stopped in
try_to_freeze().
2. an irq occurs, we disable the irq, and mark it as disabled,
and wake the thread. This wake occurs while the thread is
still within __refrigerator()
3. The thread is unfrozen, and __refrigerator() sets the threads
state back to INTERRUPTIBLE.
We then drop into schedule_timeout() with an infinite timeout and the
IRQ disabled. This prevents any further screen touches activating
the thread.
Fix this by using kthread_freezable_should_stop() which handles the
freezing issues for us outside of the hotspot where the task state
matters. Include a flag to ignore the touchscreen until it is

ARM: fix rcu stalls on SMP platforms
We can stall RCU processing on SMP platforms if a CPU sits in its idle

tpm: fix (ACPI S3) suspend regression
This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e6713fcb ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.
The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver... Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.

tg3: Fix single-vector MSI-X code
Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled. However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup. When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.
This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt. In such a configuration, the
device's multivector interrupt mode must be disabled.
