2013-11-06	ARC: Reduce #ifdef'ery for unaligned access emulation	Vineet Gupta	1	-1/+2
	Emulation not enabled is treated as if the fixup failed, so no need for special #ifdef checks. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-06-26	ARC: Remove explicit passing around of ECR	Vineet Gupta	1	-2/+2
	With ECR now part of pt_regs * No need to propagate from lowest asm handlers as arg * No need to save it in tsk->thread.cause_code * Avoid bit chopping to access the bit-fields More code consolidation, cleanup Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-02-15	ARC: Unaligned access emulation	Vineet Gupta	1	-0/+29
	ARC700 doesn't natively support unaligned access, but can be emulated -Unaligned Access Exception -Disassembly at the Fault address to find the exact insn (long/short) Also per Arnd's comment, we runtime control it using 2 sysctl knobs: * SYSCTL_ARCH_UNALIGN_ALLOW: Runtime enable/disble * SYSCTL_ARCH_UNALIGN_NO_WARN: Warn on each emulation attempt Originally contributed by Tim Yao <tim.yao@amlogic.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Tim Yao <tim.yao@amlogic.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
