The following changes since commit 6efb943b8616ec53a5e444193dccf1af9ad627b5: Linux 5.13-rc1 (2021-05-09 14:17:44 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic.git tags/asm-generic-unaligned-5.14 for you to fetch changes up to 803f4e1eab7a8938ba3a3c30dd4eb5e9eeef5e63: asm-generic: simplify asm/unaligned.h (2021-05-17 13:30:29 +0200) ---------------------------------------------------------------- asm-generic/unaligned: 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.
