Merge tag 'asm-generic-unaligned-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm/unaligned.h unification from Arnd Bergmann:
"Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally
architecture specific, with the two main variants being the
"access-ok.h" version that assumes unaligned pointer accesses always
work on a particular architecture, and the "le-struct.h" version that
casts the data to a byte aligned type before dereferencing, for
architectures that cannot always do unaligned accesses in hardware.
Based on the discussion linked below, it appears that the access-ok
version is not realiable on any architecture, but the struct version
probably has no downsides. This series changes the code to use the
same implementation on all architectures, addressing the few
exceptions separately"
