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"
