The cacheid_init() function assumes that if cpu_architecture() returns
7, the caches are VIPT_NONALIASING. The cpu_architecture() function
returns the version of the supported MMU features (e.g. TEX remapping)
but it doesn't make any assumptions about the cache type. The patch adds
the checking of the Cache Type Register for the ARMv7 format.Signed-off-by: Catalin Marinas

The target of the strex instruction to clear the exlusive monitor
is currently the top of the stack. If the store succeeeds this
corrupts r0 in pt_regs. Use the next stack location instead of
the current one to prevent any chance of corrupting an in-use
address.Signed-off-by: Seth Forshee

Impact: fix stuck NMIs and non-working oprofile on certain CPUs
Resetting the counter width of the performance counters on Intel's
Core2 CPUs, breaks the delivery of NMIs, when running in x86_64 mode.This should fix bug #12395:

Impact: fix failed EFI bootup in certain circumstances
Ying Huang found init_memory_mapping() has problem with small ranges
less than 2M when he tried to direct map the EFI runtime code out of
max_low_pfn_mapped.It turns out we never considered that case and didn't check the range...

This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was
totally wrong - the "embedded" options still exists (very much so) even
on non-embedded platforms.It's just that we don't bother with actually asking about them when
we're not embedded, we just take their default values (which is usually
'y' - the options add features that may not be worth it in a constrained
environment).Noticed-by: Andrew Morton

* 'drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
drm/i915: Fix use-before-null-check in i915_irq_emit().
drm: Avoid client deadlocks when the master disappears.
drm: Wake up all lock waiters when the master disappears.
drm: Don't return ERESTARTSYS to user-space. -
This could be triggered by a client asking to emit an irq when the device
wasn't initialized.Signed-off-by: Eric Anholt
Signed-off-by: Dave Airlie -
This is done by
1) Wake up lock waiters when we close the master file descriptor.
Not when the master structure is removed, since the latter
requires the waiters themselves to release the refcount on the
master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
Normally these clients will get a SIGPIPE when the X server dies,
but clients may also spin trying to grab the DRM lock, without
getting any sort of notification.Signed-off-by: Thomas Hellstrom

Currently only one waiter is woken up, leaving other waiters
hanging waiting for the DRM lock.Signed-off-by: Thomas Hellstrom
