#     Merge tag 'xarray-5.5' of git://git.infradead.org/users/willy/linux-dax
#     
#     Pull XArray fixes from Matthew Wilcox:
#      "Primarily bugfixes, mostly around handling index wrap-around
#       correctly.
#     
#       A couple of doc fixes and adding missing APIs.
#     
#       I had an oops live on stage at linux.conf.au this year, and it turned
#       out to be a bug in xas_find() which I can't prove isn't triggerable in
#       the current codebase. Then in looking for the bug, I spotted two more
#       bugs.
#     
#       The bots have had a few days to chew on this with no problems
#       reported, and it passes the test-suite (which now has more tests to
#       make sure these problems don't come back)"
#     
#     * tag 'xarray-5.5' of git://git.infradead.org/users/willy/linux-dax:

WARNING: vmlinux.o(.text.unlikely+0x760): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
The function free_memmap() references
the function __meminit memblock_free().
This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
