affect vmwgfx."
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/ttm: Fix buffer object metadata accounting regression v2
drm: increase DRM_OBJECT_MAX_PROPERTY to 24
drm/radeon: fix tiling and command stream checking on evergreen v3
A regression was introduced in the 3.3 rc series, commit
"drm/ttm: simplify memory accounting for ttm user v2",
causing the metadata of buffer objects created using the ttm_bo_create()
function to be accounted twice.
That causes massive leaks with the vmwgfx driver running for example
SpecViewperf Catia-03 test 2, eventually killing the app.
Furthermore, the same commit introduces a regression where
metadata accounting is leaked if a buffer object is
initialized with an illegal size. This is also fixed with this commit.
v2: Fixed an error path and removed an unused variable.

Before Kernel 3.5, no one was checking for the return value of
drm_connector_attach_property, so we never noticed that we were unable
to create some properties. Commit "drm: WARN() when
drm_connector_attach_property fails" added a WARN when we fail to
create a property, and the transition from "connector properties" to
"object properties" changed the warning message a little bit.
On i915 machines with many TV connectors we hit the maximum number of
properties (since each TV connector uses a lot of properties), so we
get a few backtraces in our logs. This commit increases the maximum
number of properties to 24 hoping we'll have enough room for
everybody.
Chris suggested that we convert this code to "lists", but I believe
this conversion can come after we make sure people's dmesgs are not
spammed by our driver.

After create config map, the new_map pointer becomes point to

Thus using new_map pointer to display the MUX_GROUP info is not correct.
Using map pointer instead to show the correct MUX_GROUP map info.

CASE. A)
as new_map is not moved and allocated like,
for (i = 0; i < MAX_ELEMS; i++) {
new_map[i] = kmalloc(numelems * size, GFP_KERNEL);
}
its freed as
for (i = 0; i < MAX_ELEMS; i++) {
kfree(new_map[i]);
}
CASE. B)
and its allocated like
new_map = kmalloc(numelems * size, GFP_KERNEL);

"drivers/gpio: gpio-nomadik: Add support for irqdomains"
changed GPIO offset calculations to have this form:
(gpio % NMK_GPIO_PER_CHIP) except in this one place for
setting sleep mode, where the conversion was all wrong, and
instead mod:ing the GPIO with the IRQ base which does not
make any sense.
So fix this up so we can use sleepmode.

When building for non-MMU based classic 68k CPU types (like the 68328 for
example) you get a compilation error:

arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’
include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here
The arch_gettimeoffset() code is included when building for these CPU types,
but it shouldn't be. Those machine types do not have
CONFIG_ARCH_USES_GETTIMEOFFSET set.
The fix is simply to conditionally include the arch_gettimeoffset() code on
that same config setting that specifies its use or not.

from the idle loop has no effect if the CPU has entered dyntick-idle
mode because the CPU has already computed its wakeup time, and posting
a timer does not cause it to be recomputed. The short-term fix is for
RCU to precompute the timeout value so that the CPU's calculation is
correct. "

regulator: anatop: Use correct __devexit_p annotation
regulator: palmas: Fix wrong kfree calls
commit 3fa2a1df90 (virtio-net: per cpu 64 bit stats (v2)) added a race
on 32bit arches.
We must use separate syncp for rx and tx path as they can be run at the
same time on different cpus. Thus one sequence increment can be lost and
readers spin forever.
