This can be ascertained within do_page_fault() since it gets the full
ECR (Exception Cause Register).
Further, for both the callers of do_page_fault(): Prot-V / D-TLB-Miss,
the cause sub-fields in ECR are same for same type of access, making the
code much more simpler.
D-TLB-Miss [LD] 0x00_21_01_00
Prot-V [LD] 0x00_23_01_00
^^
D-TLB-Miss [ST] 0x00_21_02_00
Prot-V [ST] 0x00_23_02_00
^^
D-TLB-Miss [EX] 0x00_21_03_00
Prot-V [EX] 0x00_23_03_00
^^
This helps code consolidation, which is even better when moving code from
assembler to "C".

1. For VM_EXEC based delayed dcache/icache flush, reduces the number of
flushes.
2. Makes this security feature ON by default rather than OFF before.
3. Applications can use mprotect() to selectively override this.
4. ELF binaries have a GNU_STACK segment which can easily override the
kernel default permissions.
For nested-functions/trampolines, gcc already auto-enables executable
stack in elf. Others needing this can use -Wl,-z,execstack option.

This fixes the following:
- CONFIG_ARC_SERIAL_BAUD is only defined when CONFIG_SERIAL_ARC is defined.
Make sure that it isn't referenced otherwise.
- There is no use for initializing arc_uart_info[] when CONFIG_SERIAL_ARC is
not defined.

dump_seek() does SEEK_CUR, not SEEK_SET; native binfmt_aout

Some new users of the ARM sched_clock framework are going through
the arm-soc tree. Before 38ff87f (sched_clock: Make ARM's
sched_clock generic for all architectures, 2013-06-01) the header
file was in asm, but now it's in linux. One solution would be to
do an evil merge of the arm-soc tree and fix up the asm users,
but it's easier to add a temporary asm header that we can remove
along with the few stragglers after the merge window is over.

- Fix for a regression causing a failure to turn on some devices on
some systems during initialization introduced by a recent revert of
an ACPI PM change that broke something else. Fortunately, we know
exactly what devices are affected, so we can add a fix just for them
leaving everyone else alone.
- ACPI power resources initialization fix preventing a NULL pointer
from being dereferenced in the acpi_add_power_resource() error code
path.
- ACPI dock station driver fix that adds missing locking to
write_undock().
- ACPI resources allocation fix changing the scope of an old workaround
so that it doesn't affect systems that aren't actually buggy. This
was reported a couple of days ago to fix DMA problems on some new
platforms so we need it in -stable. From Mika Westerberg.

ASoC: Updates for v3.11
Not a big release subsystem wise, the main changes have been some nice
improvements on the driver side:
- Lots of cleanups and fixes for Blackfin, SGTL5000 and UX500.
- Generalisation of the Bluetooth and HDMI stub drivers.
- New CODEC drivers for SSM2518 and RT5640.
- New machine driver for Tegra CPUs with RT5640.

Although the internal register window size is 1 MiB, the previous
ranges translation for the internal register space had a size of
0x4000000. This was done to allow the crypto and nand node to access
the corresponding 'sram' and 'nand' decoding windows.
In order to describe the hardware more accurately, we declare the
real 1 MiB internal register space in the ranges, and add a translation
entry for the nand node to access the 'nand' window.
This commit will make future improvements on the MBus DT binding easier.

ARM: at91: Consolidate time keeping and irq enable
Enable core cpuidle timekeeping and irq enabling and remove that

introduced an additional zero to the state1 (suspend) target residency.
With a periodic tick, the cpu never enters the state1 with both 10000 and
100000.
With a tickless system, it enters to state1 much more often with the
initial value, roughly x7 more.
Fix it by setting the value to 10ms again.

Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf
ARM: at91: add AIC5 support
we allocate the at91_extern_irq.
This patch makes it static and stores the non-dt extern irq in the soc
structure. It is then possible to use a at91_get_extern_irq() function
to get the value for outside of the irq driver. It is useful for passing
its value to at91_aic_init().
