In debugfs it's not enough to just set file mode to read-only to

f2fs support atomic write with following semantics:
1. open db file
2. ioctl start atomic write
3. (write db file) * n

This patch also tunes address space handler installation, making it

If a table in the initrd wasn't used by the override mechanism, the table
would be installed after initializing all RSDT/XSDT tables.

ARCH_SUPPORTS_DEBUG_PAGEALLOC provides a hook to map and unmap
pages for debugging purposes. This requires memory be mapped
with PAGE_SIZE mappings since breaking down larger mappings
at runtime will lead to TLB conflicts. Check if debug_pagealloc
is enabled at runtime and if so, map everyting
With CONFIG_DEBUG_PAGEALLOC, pages do not have the valid bit
set when free in the buddy allocator. Add an indiciation to
the page table dumping code that the valid bit is not set,
'F' for fault, to make this easier to understand.

create_mapping is only used in fixmap_remap_fdt. All the create_mapping
calls need to happen on existing translation table pages without
additional allocations. Rather than have an alloc function be called
and fail, just set it to NULL and catch its use. Also change

Hi,
This is hopefully the last update to add proper ARCH_SUPPORTS_DEBUG_PAGEALLOC
support for arm64.
Changes since v3:
- More acks
- Pulled out block check into a separate function
- Style fixups
- Comment tweaking

arm64: Drop alloc function from create_mapping

To enable UBSAN on arm64, ARCH_HAS_UBSAN_SANITIZE_ALL need to be selected.
Basic kernel bootup test is passed on arm64 with CONFIG_UBSAN_SANITIZE_ALL
enabled.
