Merge tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS updates from Paul Burton: "Here's the main MIPS pull for Linux 4.21. Core architecture changes include: - Syscall tables & definitions for unistd.h are now generated by scripts, providing greater consistency with other architectures & making it easier to add new syscalls. - Support for building kernels with no floating point support, upon which any userland attempting to use floating point instructions will receive a SIGILL. Mostly useful to shrink the kernel & as preparation for nanoMIPS support which does not yet include FP. - MIPS SIMD Architecture (MSA) vector register context is now exposed by ptrace via a new NT_MIPS_MSA regset. - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding the ASID version field sufficiently that we don't need to worry about overflow & avoiding rare issues with reused ASIDs that have been observed in the wild. - The branch delay slot "emulation" page is now mapped without write permission for the user, preventing its use as a nice location for attacks to execute malicious code from. - Support for ioremap_prot(), primarily to allow gdb or other ptrace users the ability to view their tracee's memory using the same cache coherency attribute. - Optimizations to more cpu_has_* macros, allowing more to be compile-time constant where possible. - Enable building the whole kernel with UBSAN instrumentation. - Enable building the kernel with link-time dead code & data elimination. Platform specific changes include: - The Boston board gains a workaround for DMA prefetching issues with the EG20T Platform Controller Hub that it uses. - Cleanups to Cavium Octeon code removing about 20k lines of redundant code, mostly unused or duplicate register definitions in headers. - defconfig updates for the DECstation machines, including new defconfigs for r4k & 64b machines. - Further work on Loongson 3 support. - DMA fixes for SiByte machines" * tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (95 commits) MIPS: math-emu: Write-protect delay slot emulation pages MIPS: Remove struct mm_context_t fp_mode_switching field mips: generate uapi header and system call table files mips: add system call table generation support mips: remove syscall table entries mips: add +1 to __NR_syscalls in uapi header mips: rename scall64-64.S to scall64-n64.S mips: remove unused macros mips: add __NR_syscalls along with __NR_Linux_syscalls MIPS: Expand MIPS32 ASIDs to 64 bits MIPS: OCTEON: delete redundant register definitions MIPS: OCTEON: cvmx_gmxx_inf_mode: use oldest forward compatible definition MIPS: OCTEON: cvmx_mio_fus_dat3: use oldest forward compatible definition MIPS: OCTEON: cvmx_pko_mem_debug8: use oldest forward compatible definition MIPS: OCTEON: octeon-usb: use common gpio_bit definition MIPS: OCTEON: enable all OCTEON drivers in defconfig mips: annotate implicit fall throughs MIPS: Hardcode cpu_has_mips* where target ISA allows MIPS: MT: Remove norps command line parameter MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y ...
