Subject: [PATCH v4 0/7] KASAN for arm64

For git users patches are available in git:
 	git://github.com/aryabinin/linux.git kasan/arm64v4

Changes since v3:
 - Generate KASAN_SHADOW_OFFSET in Makefile
 - zero_p*_populate() functions now return void
 - Switch x86 to generic kasan_populate_zero_shadow() too
 - Add license headers
 - fix memleak in kasan_populate_zero_shadow:
       Following code could leak memory when pgd_populate() is nop:
		void *p = early_alloc(PAGE_SIZE, NUMA_NO_NODE);
		pgd_populate(&init_mm, pgd, p);
	This was replaced by:
	     	 pgd_populate(&init_mm, pgd, early_alloc(PAGE_SIZE, NUMA_NO_NODE));

Changes since v2:
 - Rebase on top of v4.2-rc3
 - Address feedback from Catalin.
 - Print memory assignment from Linus
 - Add message about KASAN being initialized

Changes since v1:
 - Address feedback from Catalin.
 - Generalize some kasan init code from arch/x86/mm/kasan_init_64.c
    and reuse it for arm64.
 - Some bugfixes, including:
   	add missing arm64/include/asm/kasan.h
	add tlb flush after changing ttbr1
 - Add code comments.
 
Andrey Ryabinin (6):
  x86/kasan: generate KASAN_SHADOW_OFFSET in Makefile
  mm: kasan: introduce generic kasan_populate_zero_shadow()
  arm64: introduce VA_START macro - the first kernel virtual address.
  arm64: move PGD_SIZE definition to pgalloc.h
  arm64: add KASAN support
  x86/kasan: switch to generic kasan_populate_zero_shadow()

Linus Walleij (1):
  ARM64: kasan: print memory assignment
