Currently, Documentation/i2c/dev-interface describes the use of i2c_smbus_*
helper routines as static inlined functions provided by linux/i2c-dev.h. Work
has been done to refactor the linux/i2c-dev.h file in the i2c-tools project
out into its own library. As a result, these docs have become stale

Changelog:
v4 - v3
- Remove the fix of type conversion in kasan_cache_create because it has
been fix in the latest version in:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
- Change some Reviewed-by tag into Reported-by tag to avoid misleading.
---Re
The purpose of this patch is to provide set_ttbr0/get_ttbr0
to kasan_init function. The definitions of cp15 registers
should be in arch/arm/include/asm/cp15.h rather than
arch/arm/include/asm/kvm_hyp.h, so move them.

This patch initializes KASan shadow region's page table and memory.
There are two stage for KASan initializing:

Functions like memset/memmove/memcpy do a lot of memory accesses.
If bad pointer passed to one of these function it is important
to catch this. Compiler's instrumentation cannot do this since
these functions are written in assembly.
