Merge branch 'mips-for-linux-next' of git://git.linux-mips.org/pub/scm/ralf/upstream-sfr
Pull MIPS updates from Ralf Baechle: - Support for Imgtec's Aptiv family of MIPS cores. - Improved detection of BCM47xx configurations. - Fix hiberation for certain configurations. - Add support for the Chinese Loongson 3 CPU, a MIPS64 R2 core and systems. - Detection and support for the MIPS P5600 core. - A few more random fixes that didn't make 3.14. - Support for the EVA Extended Virtual Addressing - Switch Alchemy to the platform PATA driver - Complete unification of Alchemy support - Allow availability of I/O cache coherency to be runtime detected - Improvments to multiprocessing support for Imgtec platforms - A few microoptimizations - Cleanups of FPU support - Paul Gortmaker's fixes for the init stuff - Support for seccomp * 'mips-for-linux-next' of git://git.linux-mips.org/pub/scm/ralf/upstream-sfr: (165 commits) MIPS: CPC: Use __raw_ memory access functions MIPS: CM: use __raw_ memory access functions MIPS: Fix warning when including smp-ops.h with CONFIG_SMP=n MIPS: Malta: GIC IPIs may be used without MT MIPS: smp-mt: Use common GIC IPI implementation MIPS: smp-cmp: Remove incorrect core number probe MIPS: Fix gigaton of warning building with microMIPS. MIPS: Fix core number detection for MT cores MIPS: MT: core_nvpes function to retrieve VPE count MIPS: Provide empty mips_mt_set_cpuoptions when CONFIG_MIPS_MT=n MIPS: Lasat: Replace del_timer by del_timer_sync MIPS: Malta: Setup PM I/O region on boot MIPS: Loongson: Add a Loongson-3 default config file MIPS: Loongson 3: Add CPU hotplug support MIPS: Loongson 3: Add Loongson-3 SMP support MIPS: Loongson: Add Loongson-3 Kconfig options MIPS: Loongson: Add swiotlb to support All-Memory DMA MIPS: Loongson 3: Add serial port support MIPS: Loongson 3: Add IRQ init and dispatch support MIPS: Loongson 3: Add HT-linked PCI support ...
