Bitmap patches for v6.0-rc1
This branch consists of:
Qu Wenruo:
lib: bitmap: fix the duplicated comments on bitmap_to_arr64()
https://lore.kernel.org/lkml/0d85e1dbad52ad7fb5787c4432bdb36cbd24f632.1656063005.git.wqu@suse.com/
Alexander Lobakin:
bitops: let optimize out non-atomic bitops on compile-time constants
https://lore.kernel.org/lkml/20220624121313.2382500-1-alexandr.lobakin@intel.com/T/
Yury Norov:
lib: cleanup bitmap-related headers
https://lore.kernel.org/linux-arm-kernel/YtCVeOGLiQ4gNPSf@yury-laptop/T/#m305522194c4d38edfdaffa71fcaaf2e2ca00a961
Alexander Lobakin:
x86/olpc: fix 'logical not is only applied to the left hand side'
https://www.spinics.net/lists/kernel/msg4440064.html
Yury Norov:
lib/nodemask: inline wrappers around bitmap
https://lore.kernel.org/all/20220723214537.2054208-1-yury.norov@gmail.com/
----------------------------------------------------------------
The patch "headers/deps: mm: Split <linux/gfp_types.h> out of <linux/gfp.h>"
conflicts with 70c248aca9e7e ("mm: kasan: Skip unpoisoning of user pages").
The gfp_types patch moves macros from gfp.h to gfp_types.h, but the
70c248aca9e7e modifies original gfp.h, and therefore git can't apply
gfp_types patch cleanly. The solution is to propagate the following
change from gfp.h to new gfp_types.h:
#define GFP_DMA32 __GFP_DMA32
#define GFP_HIGHUSER (GFP_USER | __GFP_HIGHMEM)
#define GFP_HIGHUSER_MOVABLE (GFP_HIGHUSER | __GFP_MOVABLE | \
- __GFP_SKIP_KASAN_POISON)
+ __GFP_SKIP_KASAN_POISON | __GFP_SKIP_KASAN_UNPOISON)
#define GFP_TRANSHUGE_LIGHT ((GFP_HIGHUSER_MOVABLE | __GFP_COMP | \
__GFP_NOMEMALLOC | __GFP_NOWARN) & ~__GFP_RECLAIM)
#define GFP_TRANSHUGE (GFP_TRANSHUGE_LIGHT | __GFP_DIRECT_RECLAIM)
