Subsystem:
alpha port, m68k architecture, microblaze architecture, parisc architecture, sparc + ultrasparc (sparc/sparc64), tensilica xtensa port (xtensa), the rest, x86 architecture (32-bit and 64-bit) · Maintainers:

From: Arnd Bergmann <arnd@arndb.de> There are several architectures that just duplicate the contents of asm-generic/unaligned.h, so change those over to use the file directly, to make future modifications easier. The exceptions are: - arm32 sets HAVE_EFFICIENT_UNALIGNED_ACCESS, but wants the unaligned-struct version - ppc64le disables HAVE_EFFICIENT_UNALIGNED_ACCESS but includes the access-ok version - most m68k also uses the access-ok version without setting HAVE_EFFICIENT_UNALIGNED_ACCESS. - sh4a has a custom inline asm version - openrisc is the only one using the memmove version that generally leads to worse code.
