Pull MIPS updates from James Hogan:
 "These are the main MIPS changes for 4.15.

  Fixes:
   - ralink: Fix MT7620 PCI build issues (4.5)
   - Disable cmpxchg64() and HAVE_VIRT_CPU_ACCOUNTING_GEN for 32-bit SMP
     (4.1)
   - Fix MIPS64 FP save/restore on 32-bit kernels (4.0)
   - ptrace: Pick up ptrace/seccomp changed syscall numbers (3.19)
   - ralink: Fix MT7628 pinmux (3.19)
   - BCM47XX: Fix LED inversion on WRT54GSv1 (3.17)
   - Fix n32 core dumping as o32 since regset support (3.13)
   - ralink: Drop obsolete USB_ARCH_HAS_HCD select

  Build system:
   - Default to "generic" (multiplatform) system type instead of IP22
   - Use generic little endian MIPS32 r2 configuration as default
     defconfig instead of ip22_defconfig

  FPU emulation:
   - Fix exception generation for certain R6 FPU instructions

  SMP:
   - Allow __cpu_number_map to be larger than NR_CPUS for sparse CPU id
     spaces

  Miscellaneous:
   - Add iomem resource for kernel bss section for kexec/kdump
   - Atomics: Nudge writes on bit unlock
   - DT files: Standardise "ok" -> "okay"

  Minor cleanups:
   - Define virt_to_pfn()
   - Make thread_saved_pc static
   - Simplify 32-bit sign extension in __read_64bit_c0_split()
   - DMA: Use vma_pages() helper
   - FPU emulation: Replace unsigned with unsigned int
   - MM: Removed unused lastpfn
   - Alchemy: Make clk_ops const
   - Lasat: Use setup_timer() helper
   - ralink: Use BIT() in MT7620 PCI driver

  Platform support:

  BMIPS:
  - Enable HARDIRQS_SW_RESEND

  Broadcom BCM63XX:
  - Add clkdev lookup support
  - Update clk driver, UART driver, DTs to handle named refclk from DTs
  - Split apart various clocks to more closely match hardware
  - Add ethernet clocks

  Cavium Octeon:
  - Remove usage of cvmx_wait() in favour of __delay()

  ImgTec Pistachio:
  - DT: Drop deprecated dwmmc num-slots property

  Ingenic JZ4780:
  - Add NFS root to Ci20 defconfig
  - Add watchdog to Ci20 DT & defconfig, and allow building of watchdog
    driver with this SoC

  Generic (multiplatform):
  - Migrate xilfpga (MIPSfpga) platform to the generic platform

  Lantiq xway:
  - Fix ASC0/ASC1 clocks"
