sh: wire up SET/GET_UNALIGN_CTL. 2010-02-23T03:56:30+00:00 Paul Mundt lethal@linux-sh.org 2010-02-23T03:56:30+00:00 94ea5e449ae834af058ef005d16a8ad44fcf13d6 This hooks up the SET/GET_UNALIGN_CTL knobs cribbing the bulk of it from the PPC and ia64 implementations. The thread flags happen to be the logical inverse of what the global fault mode is set to, so this works out pretty cleanly. By default the global fault mode is used, with tasks now being able to override their own settings via prctl(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh64: Fix up PC casting in unaligned fixup notifier with 32bit ABI. 2010-01-19T06:41:50+00:00 Paul Mundt lethal@linux-sh.org 2010-01-19T06:41:50+00:00 88ea1a445a84fcfbedb810c01e84d6711352bd82 Presently the build bails with the following: CC arch/sh/mm/alignment.o cc1: warnings being treated as errors arch/sh/mm/alignment.c: In function 'unaligned_fixups_notify': arch/sh/mm/alignment.c:69: warning: cast to pointer from integer of different size arch/sh/mm/alignment.c:74: warning: cast to pointer from integer of different size make[2]: *** [arch/sh/mm/alignment.o] Error 1 This is due to the fact that regs->pc is always 64-bit, while the pointer size depends on the ABI.

This is due to the fact that regs->pc is always 64-bit, while the pointer size
depends on the ABI. Wrapping through instruction_pointer() takes care of the
