From 6510d41954dc6a9c8b1dbca7eaca0f23195ca727 Mon Sep 17 00:00:00 2001 From: Harvey Harrison Date: Tue, 29 Apr 2008 01:03:30 -0700 Subject: kernel: Move arches to use common unaligned access 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.
