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"
