https://lore.kernel.org/lkml/20220624121313.2382500-1-alexandr.lobakin@intel.com/T/

Yury Norov:
lib: cleanup bitmap-related headers

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)
