The 32-bit siginfo is a different binary format than the 64-bit

to convert the kernel's 64-bit version to a 32-bit version that
userspace can grok.
We've added a few features to siginfo over the past few years a

Hi all,
I've been working with Ben Dooks to get a big-endian kernel working on
my Exynos 4412 board. Primarily this series consists of:
- Replacing the __raw_{read,write}l accessors, which aren't
endian-clean, with their respective {read,write}l_relaxed versions
across various drivers.
Fix the Samsung pwm timer access code to deal with kernels built for big
endian operation.

For KASAN builds:
- switch SLUB allocator to using stackdepot instead of storing the
allocation/deallocation stacks in the objects;
- define SLAB_RED_ZONE, SLAB_POISON, SLAB_STORE_USER to zero,
effectively disabling these debug features, as they're redundant in
the presence of KASAN;

Use SETC instead of SBB to return the value of CF from assembly. Using

Use CC_SET()/CC_OUT() and static_cpu_has(). This produces code good
enough to eliminate ad hoc use of alternatives in ,
greatly simplifying the code.
While we are at it, make x86_init_rdrand() compile out completely if
we don't need it.

Change the lexical defintion of the GEN_*_RMWcc() macros to not take
the condition code as a quoted string. This will help support
changing them to use the new __GCC_ASM_FLAG_OUTPUTS__ feature in a
