ARC: perf: ARC 700 PMU doesn't support sampling events

2013-11-15T05:22:28Z

The ARC 700 does not have an interrupt associated with it, and as such it cannot trigger when a counter overflows. As the counters are 48 bit, it will usually take at least 100 days before a counter overflows, so for mere counting of events, there is no problem. Sampling is not supported though.

smp, ARC: kill SMP single function call interrupt

2013-11-07T09:04:31Z

Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.

ARC: [SMP] Fix build failures for large NR_CPUS

2013-11-06T05:11:46Z

ST.as only takes S9 (255) for offset. This was going out of range when accessing a task_struct field with 4k NR_CPUS (due to 128b of coumaks itself in there). Workaround by using an intermediate register to do the address scaling. There is some duplication of fix for ctx_sw.c and ctx_sw_asm.S however given that C version will go away soon I'm not bothering to factor out the common code.
