Add an optimized mm_zero_struct_page(), so struct page's are zeroed without
calling memset(). We do eight to ten regular stores based on the size of
struct page. Compiler optimizes out the conditions of switch() statement.
SPARC-M6 with 15T of memory, single thread performance:
Changelog:
v7 - v6
- Addressed comments from Michal Hocko
- memblock_discard() patch was removed from this series and integrated
separately
- Fixed bug reported by kbuild test robot new patch:
mm: zero reserved and unavailable struct pages
- Removed patch
x86/mm: reserve only exiting low page
To optimize the performance of struct page initialization,
vmemmap_populate() will no longer zero memory.
We must explicitly zero the memory that is allocated by vmemmap_populate()
for kasan, as this memory does not go through struct page initialization
path.

Review
Remove duplicating code by using common functions
vmemmap_pud_populate and vmemmap_pgd_populate.

Some memory is reserved but unavailable: not present in memblock.memory
(because not backed by physical pages), but present in memblock.reserved.
Such memory has backing struct pages, but they are not initialized by going
through __init_single_page().
In some cases these struct pages are accessed

Without deferred struct page feature (CONFIG_DEFERRED_STRUCT_PAGE_INIT),
flags and other fields in "struct page"es are never changed prior to first
initializing struct pages by going through __init_single_page().
With deferred struct page feature enabled there is a case where we set some

vmemmap_alloc_block() will no longer zero the block, so zero memory
at its call sites for everything except struct pages. Struct page memory
is zero'd by struct page initialization.
Replace allocators in sprase-vmemmap to use the non-zeroing version. So,
we will get the performance improvement by
* A new variant of memblock_virt_alloc_* allocations:
memblock_virt_alloc_try_nid_raw()
- Does not zero the allocated memory
- Does not panic if request cannot be satisfied
* optimize early system hash allocations
Clients can call alloc_large_system_hash() with flag: HASH_ZERO to specify

This adds a statically sized closed hash table implementation with
low memory and CPU overhead. The API is inspired by kfifo.
Storing, retrieving and deleting data does not involve any dynamic
memory management, which makes it ideal for use in interrupt context.
Static memory usage per entry compr

I suggest to drop sync_r4k completely, because it is inaccurate. You
can use IPI to synchronize count/compare instead, as Loongson-3 does.

The imx274 is a Sony CMOS image sensor that has 1/2.5 image size.
It supports up to 3840x2160 (4K) 60fps, 1080p 120fps. The interface
is 4-lane MIPI running at 1.44Gbps each.
This driver has been tested on Xilinx ZCU102 platform with a Leopard
LI-IMX274MIPI-FMC camera board.
