These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,
the list should be kept in alphabetical order when
resolving.

If this option is disabled, you allow userspace (root) access to all

of memory, including kernel and userspace memory. Accidental
|
|
access to this is obviously disastrous, but specific access can
|
|
be used by people debugging the kernel.
|

If this option is switched on, the /dev/mem file only allows

userspace access to memory mapped peripherals.

help
|

When a user program crashes due to an exception, the kernel can

|
print a brief message explaining what the problem was. This is
|
|
sometimes helpful for debugging but serves no purpose on a
|
|
production system. Most people should say N here.
|
|
|
|
In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls
|
|
4 - invalid data aborts
|
|
8 - SIGSEGV faults
