MIPS: Wire up io_pgetevents syscall (2018-06-19 21:14:29 -0700)
----------------------------------------------------------------
A few MIPS fixes for 4.18:
- A GPIO device name fix for a regression in v4.15-rc1.
- An errata workaround for the BCM5300X platform.
- A fix to ftrace function graph tracing, broken for a long time with
the fix applying cleanly back as far as v3.17.
- Addition of read barriers to in{b,w,l,q}() functions, matching
behavior of other architectures & mirroring the equivalent addition
to read{b,w,l,q} in v4.17-rc2.
Plus changes to wire up new syscalls introduced in the 4.18 cycle:
- Restartable sequences support is added, including MIPS support in
the selftests.
- io_pgetevents is wired up.
