Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Ben Herrenschmidt:
"The main thing that caused problem was that CONFIG_CPU_LITTLE_ENDIAN
got turned on with allyesconfig and such, which is not a very good
idea especially since it requires a newer toolchain than what most
people have.
So we turned it into a choice instead that defaults to big endian"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc/windfarm: Fix XServe G5 fan control Makefile issue
arch/powerpc/kernel: Use %12.12s instead of %12s to avoid memory overflow
powerpc/signals: Improved mark VSX not saved with small contexts fix
powerpc/kdump: Adding symbols in vmcoreinfo to facilitate dump filtering
powerpc: allyesconfig should not select CONFIG_CPU_LITTLE_ENDIAN
powerpc: Fix error when cross building TAGS & cscope
powerpc/booke: Only check for hugetlb in flush if vma != NULL
powerpc/85xx: typo in dts: "interupt" (four devices)
powerpc/8xx: mfspr SPRN_TBRx in lieu of mftb/mftbu is not supported
powerpc/corenet64: compile with CONFIG_E{5,6}500_CPU well
