Changes in v3:
- Fixed krealloc tag assigning without changing kasan_kmalloc hook and
  added more comments to the assign_tag function while at it.
- Moved ARCH_SLAB_MINALIGN definition to arch/arm64/include/asm/cache.h.

Changes in v2:
- Added "kasan: make tag based mode work with CONFIG_HARDENED_USERCOPY"
  patch.
- Added "kasan: fix krealloc handling for tag-based mode" patch.

Andrey Konovalov (3):
  kasan, arm64: use ARCH_SLAB_MINALIGN instead of manual aligning
  kasan: make tag based mode work with CONFIG_HARDENED_USERCOPY
  kasan: fix krealloc handling for tag-based mode
