Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle: - three fixes for 3.15 that didn't make it in time - limited Octeon 3 support. - paravirtualization support - improvment to platform support for Netlogix SOCs. - add support for powering down the Malta eval board in software - add many instructions to the in-kernel microassembler. - add support for the BPF JIT. - minor cleanups of the BCM47xx code. - large cleanup of math emu code resulting in significant code size reduction, better readability of the code and more accurate emulation. - improvments to the MIPS CPS code. - support C3 power status for the R4k count/compare clock device. - improvments to the GIO support for older SGI workstations. - increase number of supported CPUs to 256; this can be reached on certain embedded multithreaded ccNUMA configurations. - various small cleanups, updates and fixes * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (173 commits) MIPS: IP22/IP28: Improve GIO support MIPS: Octeon: Add twsi interrupt initialization for OCTEON 3XXX, 5XXX, 63XX DEC: Document the R4k MB ASIC mini interrupt controller DEC: Add self as the maintainer MIPS: Add microMIPS MSA support. MIPS: Replace calls to obsolete strict_strto call with kstrto* equivalents. MIPS: Replace obsolete strict_strto call with kstrto MIPS: BFP: Simplify code slightly. MIPS: Call find_vma with the mmap_sem held MIPS: Fix 'write_msa_##' inline macro. MIPS: Fix MSA toolchain support detection. mips: Update the email address of Geert Uytterhoeven MIPS: Add minimal defconfig for mips_paravirt MIPS: Enable build for new system 'paravirt' MIPS: paravirt: Add pci controller for virtio MIPS: Add code for new system 'paravirt' MIPS: Add functions for hypervisor call MIPS: OCTEON: Add OCTEON3 to __get_cpu_type MIPS: Add function get_ebase_cpunum MIPS: Add minimal support for OCTEON3 to c-r4k.c ...
