Deng-Cheng Zhu	6dbd972850	MIPS: define local_xchg from xchg_local to atomic_long_xchg ... Perf-events is now using local_t helper functions internally. There is a use of local_xchg(). On MIPS, this is defined to xchg_local() which is missing in asm/system.h. This patch re-defines local_xchg() in asm/local.h to atomic_long_xchg(). Then Perf-events can pass the build.

David Daney	b791d1193a	MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC. ... On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.
