As usual patches available in git
git://github.com/aryabinin/linux.git kasan/arm64v7
Changes since v6:
- Rebased on top of arm64/for-next/core:
e8f3010f7326c00368dbc057bd052bec80dfc072 ("arm64/efi: isolate EFI stub from the kernel proper")
This should fix boot as an EFI application once again.
Changes since v5:
- Rebase on top of 4.3-rc1
- Fixed EFI boot.
- Updated Doc/features/KASAN.
Changes since v4:
- Generate KASAN_SHADOW_OFFSET using 32 bit arithmetic
- merge patches x86/kasan: switch to generic kasan_populate_zero_shadow()
and mm: introduce generic kasan_populate_zero_shadow() into one.
- remove useless check for start != 0 in clear_pgds()
- Don't generate KASAN_SHADOW_OFFSET in Makefile for x86,
assign it in Makefile.kasan if CONFIG_KASAN_SHADOW_OFFSET was defined.
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.
