Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
"Fixes for a number of small glitches in various corners of the MIPS
tree. No particular areas is standing out.
With this applied all MIPS defconfigs are building fine. No merge
conflicts are expected."
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: Delete definition of SA_RESTORER.
MIPS: Fix ISA level which causes secondary cache init bypassing and more
MIPS: Fix build error cavium-octeon without CONFIG_SMP
MIPS: Kconfig: Rename SNIPROM too
MIPS: Alchemy: Fix typo "CONFIG_DEBUG_PCI"
MIPS: Unbreak function tracer for 64-bit kernel.
