Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
- Properly setup irq handling for ATH79 platforms
- Fix bootmem mapstart calculation for contiguous maps
- Handle little endian and older CPUs correct in BPF
- Fix console for Fulong 2E systems
- Handle FTLB correctly on R6 CPUs
- Fixes for CM, GIC and MAAR support code
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: Initialise MAARs on secondary CPUs
MIPS: print MAAR configuration during boot
MIPS: mm: compile maar_init unconditionally
irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.
irqchip: mips-gic: Convert CPU numbers to VP IDs.
MIPS: CM: Provide a function to map from CPU to VP ID.
MIPS: Fix FTLB detection for R6
MIPS: cpu-features: Add cpu_has_ftlb
MIPS: ATH79: Add irq chip ar7240-misc-intc
MIPS: ATH79: Set missing irq ack handler for ar7100-misc-intc irq chip
MIPS: BPF: Fix build on pre-R2 little endian CPUs
MIPS: BPF: Avoid unreachable code on little endian
MIPS: bootmem: Fix mapstart calculation for contiguous maps
MIPS: Fix console output for Fulong2e system
