Merge tag 'mips_4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips
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" * tag 'mips_4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips: (46 commits) MIPS: Add iomem resource for kernel bss section. MIPS: cmpxchg64() and HAVE_VIRT_CPU_ACCOUNTING_GEN don't work for 32-bit SMP MIPS: BMIPS: Enable HARDIRQS_SW_RESEND MIPS: pci: Make use of the BIT() macro inside the mt7620 driver MIPS: pci: Remove KERN_WARN instance inside the mt7620 driver MIPS: pci: Remove duplicate define in mt7620 driver MIPS: ralink: Fix typo in mt7628 pinmux function MIPS: ralink: Fix MT7628 pinmux MIPS: Fix odd fp register warnings with MIPS64r2 watchdog: jz4780: Allow selection of jz4740-wdt driver MIPS/ptrace: Update syscall nr on register changes MIPS/ptrace: Pick up ptrace/seccomp changed syscalls MIPS: Fix an n32 core file generation regset support regression MIPS: Fix MIPS64 FP save/restore on 32-bit kernels MIPS: page.h: Define virt_to_pfn() MIPS: Xilfpga: Switch to using generic defconfigs MIPS: generic: Add support for MIPSfpga MIPS: Set defconfig target to a generic system for 32r2el MIPS: Kconfig: Set default MIPS system type as generic MIPS: DTS: Remove num-slots from Pistachio SoC ...
