Linus Torvalds 89261c5702 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.
