Subject: [PATCH v2 0/3] Add some perf support for mips

v2: add R26 and R27 to the enum perf_event_mips_regs in patch #1

Tiezhu Yang (3):
  MIPS: kernel: Support extracting off-line stack traces from user-space
    with perf
  perf tools: Support mips unwinding and dwarf-regs
  perf tools: Generate mips syscalls_n64.c syscall table
