2017-07-26	kasan: Allow kasan_check_read/write() to accept pointers to volatiles	Dmitry Vyukov
	Currently kasan_check_read/write() accept 'const void', make them accept 'const volatile void'. This is required for instrumentation of atomic operations and there is just no reason to not allow that.

2016-05-20	mm/kasan: add API to check memory regions	Andrey Ryabinin
	Memory access coded in an assembly won't be seen by KASAN as a compiler can instrument only C code. Add kasan_check_[read,write]() API which is going to be used to check a certain memory range.
