  MIPS: math-emu: Write-protect delay slot emulation pages (2018-12-20 10:00:01 

Here's the main MIPS pull for Linux 4.21. Core architecture changes

 - 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

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.
