Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
"Another round of MIPS fixes for 4.5:
- Fix JZ4780 build with DEBUG_ZBOOT and MACH_JZ4780
- Fix build with DEBUG_ZBOOT and MACH_JZ4780
- Fix issue with uninitialised temp_foreign_map
- Fix awk regex compile failure with certain versions of awk. At
this time, the sole user, ld-ifversion, is only used on MIPS"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: smp.c: Fix uninitialised temp_foreign_map
MIPS: Fix build error when SMP is used without GIC
ld-version: Fix awk regex compile failure
MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4780
