kernel/linux.git/include/asm-xtensa/unaligned.h, branch linux-2.6.28.yLinux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=linux-2.6.28.y2008-04-29T15:06:27+00:00kernel: Move arches to use common unaligned access2008-04-29T15:06:27+00:00Harvey Harrisonharvey.harrison@gmail.com2008-04-29T08:03:30+00:00urn:sha1:6510d41954dc6a9c8b1dbca7eaca0f23195ca727
Unaligned access is ok for the following arches:
cris, m68k, mn10300, powerpc, s390, x86
Arches that use the memmove implementation for native endian, and
the byteshifting for the opposite endianness.
h8300, m32r, xtensa
Packed struct for native endian, byteshifting for other endian:
alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh
m86knommu is generic_be for Coldfire, otherwise unaligned access is ok.
frv, arm chooses endianness based on compiler settings, uses the byteshifting
versions. Remove the unaligned trap handler from frv as it is now unused.
v850 is le, uses the byteshifting versions for both be and le.
Remove the now unused asm-generic implementation.
