This reverts commit 14f0aa359365e8a93a77b71e3b840274b9b4dcb1.
That commit was needed earlier because system call restarting for
OABI (compat) required an executable stack and thus had problems
with NX. Since ab72b00734ae4d0b ("ARM: Fix signal restart issues
with NX and OABI compat") has reworked the code to not require an
executable stack anymore, we can re-enable NX support for kernels
with OABI (compat) support.

Marc reported that the BUG_ON in clockevents_notify() triggers on his
system. This happens because the kernel tries to remove an active
clock event device (used for broadcasting) from the device list.
The handling of devices which can be used as per cpu device and as a
global broadcast device is suboptimal.
The simplest solution for now (and for stable) is to check whether the
device is used as global broadcast device, but this needs to be
revisited.
[ tglx: restored the cpuweight check and massaged the changelog ]

When a card instance with a higher card number is registered, warning
messages are spewed eventually with stack traces due to the invalid minor
number for OSS device registration. For example, thinkpad-acpi registers
the card number 29 as default, and you'll see always these messages.
This is rather confusing (and worries users), thus better to return
simply the error code.

flush(void)
Because of the include of the decompress_inflate.c file from
boot/compress/misc.c, there are different flush() defines:
In file included from arch/arm/boot/compressed/misc.c:249:
arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
Fix this by removing the define of flush() in misc.c for
CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
and that is being included unconditionally.
Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug
for those platforms.

We can race with the unmount of an fs and the stopping of a kthread where we
will free the block group before we're done using it. The reason for this is
because we do not hold a reference on the block group while its caching, since
the allocator drops its reference once it exits or moves on to the next block
group. This patch fixes the problem by taking a reference to the block group
before we start caching and dropping it when we're done to make sure all
accesses to the block group are safe. Thanks,

Currently orphan cleanup only ever gets triggered if we cross subvolumes during
a lookup, which means that if we just mount a plain jane fs that has orphans in
it, they will never get cleaned up. This results in panic's like these
http://www.kerneloops.org/oops.php?number=1109085
where adding an orphan entry results in -EEXIST being returned and we panic. In
order to fix this, we check to see on lookup if our root has had the orphan
cleanup done, and if not go ahead and do it. This is easily reproduceable by
running this testcase
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <string.h>
#include <unistd.h>
#include <stdio.h>
int main(int argc, char **argv)
{
char data[4096];
char newdata[4096];
int fd1, fd2;
memset(data, 'a', 4096);
memset(newdata, 'b', 4096);
while (1) {
int i;
fd1 = creat("file1", 0666);
if (fd1 < 0)
break;
for (i = 0; i < 512; i++)
write(fd1, data, 4096);
fsync(fd1);
close(fd1);
fd2 = creat("file2", 0666);
if (fd2 < 0)
break;
ftruncate(fd2, 4096 * 512);
for (i = 0; i < 512; i++)
write(fd2, newdata, 4096);
close(fd2);
i = rename("file2", "file1");
unlink("file1");
}
return 0;
}
and then pulling the power on the box, and then trying to run that test again

Btrfs: fix missing last-entry in readdir(3)
When one does a 32-bit readdir(3), the last entry of a directory is
missing. This is however not due to passing a large value to filldir,
but it seems to have to do with glibc doing telldir or something
quirky. In any case, this patch fixes it in practice.

On most cards the DisplayPort connector is created with 2 encoders sharing
a single SOR (for native DP, and for DVI-over-DP). The previous logic
for turning off unused encoders didn't take into account that we could
have multiple drm_encoders on a single hw encoder and ended up turning off
encoders that were actually being used still.
This patch fixes that issue. We probably want to look at something a bit
better later on, and only expose one drm_encoder per hw encoder block.

Currently, we take down the sgdma engine without evicting all buffers
from VRAM.
The TTM device release will try to evict anything in VRAM to GART
memory, but this will fail since sgdma has already been taken down.
This causes an infinite loop in kernel mode on module unload.
It usually doesn't happen because there aren't any buffer on close.
However, if the GPU is locked up, this condition is easily triggered.
This patch fixes it in the simplest way possible by cleaning VRAM
right before cleaning SGDMA memory.

Currently Nouveau is unable to dismiss DMA_VTX_PROTECTION errors,
which results in an infinite loop in the interrupt handler.
These errors are caused both by bugs in the Gallium driver and by
user-specified index buffers with out of bounds indices.
By mmio-tracing the nVidia drivers, I found out how this is done.
On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000,
always getting the value 4, and then writes 4 back to 0x402000.
This patch adds that logic by reading 0x402000 and writing the same
value back.
It's unclear what should happen if the value read is not 4, and
the current approach might not be the correct one.
To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining
ELTOBJ to 1 and replacing indices with huge out of bounds integers.
Without this patch, the GPU and/or kernel should lock up.
With this patch, it should misrender as expected but not lock up.
The errors are still logged since they are useful for development.
This has been tested on NV49 and may not work on other cards.
To find out how things work on other cards, run the aforementioned
test using the blob with mmiotrace and grep for a read of the PGRAPH
source register.

The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes. It does this first by searching the real symbol with the normal
unprefixed symbol. But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for. On non-prefixed arches, this is effectively the same thing,
so there is no problem. On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways. But every
once in a blue moon, you get the right page alignment and it segfaults.
For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name". The substring will thus return
one byte into "symbol" and store it into "match". But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage. i.e. the code ends up doing:
char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';
