V4.19 backport of spectre patches from Russell M. King's spectre branch.
Patches have been kvm-unit-test'ed on an arndale, run through kernelci, and
handed off to ARM for functional testing.

Julien Thierry (10):
  ARM: 8789/1: signal: copy registers using __copy_to_user()
  ARM: 8790/1: signal: always use __copy_to_user to save iwmmxt context
  ARM: 8791/1: vfp: use __copy_to_user() when saving VFP state
  ARM: 8792/1: oabi-compat: copy oabi events using __copy_to_user()
  ARM: 8793/1: signal: replace __put_user_error with __put_user
  ARM: 8794/1: uaccess: Prevent speculative use of the current
    addr_limit
  ARM: 8795/1: spectre-v1.1: use put_user() for __put_user()
  ARM: 8796/1: spectre-v1,v1.1: provide helpers for address sanitization
  ARM: 8797/1: spectre-v1.1: harden __copy_to_user
  ARM: 8810/1: vfp: Fix wrong assignement to ufp_exc

Russell King (7):
  ARM: make lookup_processor_type() non-__init
  ARM: split out processor lookup
  ARM: clean up per-processor check_bugs method call
  ARM: add PROC_VTABLE and PROC_TABLE macros
  ARM: spectre-v2: per-CPU vtables to work around big.Little systems
  ARM: ensure that processor vtables is not lost after boot
  ARM: fix the cockup in the previous patch
