Pull MIPS fixes from Ralf Baechle:
 "This is the first round of MIPS fixes for 4.6:

   - Fix spelling mistakes all over arch/mips
   - Provide __bswapsi2 so XZ kernel compression will build with older GCC
   - ATH79 clock fixes.
   - Fix clock-rated copy-paste erros in ATH79 DTS.
   - Fix gisb-arb compatible string for 7435 BMIPS
   - Enable NAND and UBIFS support in CI20.
   - Fix BUG() assertion caused by inapropriate smp_processor_id() use.
   - Fix exception handling issues for the sake of debuggers
   - Fix the last remaining instance of irq_to_gpio in the db1xxx_ss PCMCIA code
   - Fix MSA unaligned load failures
   - Panic if kernel is configured for a not TLB-supported page size
   - Bail out on unsupported relocs in modules.
   - Partial fix for Qemu breakage after recent IPI rewrite
   - Wire up the preadv2 and pwrite2 syscalls
   - Fix the ar724x clock calculation"
