* sparc: Hook up renameat2 syscall.David S. Miller2014-07-224-1/+6

* locking/mutex: Disable optimistic spinning on some architecturesPeter Zijlstra2014-07-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The optimistic spin code assumes regular stores and cmpxchg() play nice; this is found to not be true for at least: parisc, sparc32, tile32, metag-lock1, arc-!llsc and hexagon. There is further wreckage, but this in particular seemed easy to trigger, so blacklist this. Opt in for known good archs.

* nmi: provide the option to issue an NMI back trace to every cpu but currentAaron Tomlin2014-06-242-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | Sometimes it is preferred not to use the trigger_all_cpu_backtrace() routine when one wants to avoid capturing a back trace for current. For instance if one was previously captured recently. This patch provides a new routine namely trigger_allbutself_cpu_backtrace() which offers the flexibility to issue an NMI to every cpu but current and capture a back trace accordingly. Patch x86 and sparc to support new routine.

| * sparc32: remove cast from output constraints in math asm statementsSam Ravnborg2014-05-192-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following asm statements generated a sparse warning: asm("addcc \n\t" : "=r" (((USItype)(r2))) warning: asm output is not an lvalue When asking on the sparse mailing list Linus replyed: " Those casts to (USItype) are all pointless to begin with (since the values are of that type already!) and they mean that the expression isn't something you can assign to (lvalue). " In the math emulation code drop all casts in the output parts of the asm statements. This fixes a lot of "warning: asm output is not an lvalue" sparse warnings in math_32.c.
