kasan: rename kasan_zero_page to kasan_early_shadow_page

2018-12-28T20:11:43+00:00

With tag based KASAN mode the early shadow value is 0xff and not 0x00, so
this patch renames kasan_zero_(page|pte|pmd|pud|p4d) to
kasan_early_shadow_(page|pte|pmd|pud|p4d) to avoid confusion.

memblock: replace alloc_bootmem_low_pages with memblock_alloc_low

2018-10-31T15:54:15+00:00

The alloc_bootmem_low_pages() function allocates PAGE_SIZE aligned regions
from low memory. memblock_alloc_low() with alignment set to PAGE_SIZE does
exactly the same thing.

xtensa: remove ZONE_DMA

2018-10-15T19:36:20+00:00

ZONE_DMA is intended for magic < 32-bit pools (usually ISA DMA), which
isn't required on xtensa.  Move all the non-highmem memory into
ZONE_NORMAL instead to match other architectures.

mm: convert return type of handle_mm_fault() caller to vm_fault_t

2018-08-17T23:20:28+00:00

Use new return type vm_fault_t for fault handler.  For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno.  Once all instances are converted, vm_fault_t will become a
distinct type.

Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t")

In this patch all the caller of handle_mm_fault() are changed to return
vm_fault_t type.
