Hi Linus, Greg,

I'm sending the pull request for 4.20 slightly earlier as I'm on holiday
next week (not in Edinburgh). Apart from some new arm64 features and
clean-ups, this request also contains the core mmu_gather changes for
tracking the levels of the page table being cleared and a minor update
to the generic compat_sys_sigaltstack() introducing COMPAT_SIGMINSKSZ.

Thanks.

The following changes since commit 57361846b52bc686112da6ca5368d11210796804:

  arm64: KVM: Guests can skip __install_bp_hardening_cb()s HYP work (2018-10-19 15:37:25 +0100)

----------------------------------------------------------------
arm64 updates for 4.20:

- Core mmu_gather changes which allow tracking the levels of page-table
  being cleared together with the arm64 low-level flushing routines

- Support for the new ARMv8.5 PSTATE.SSBS bit which can be used to
  mitigate Spectre-v4 dynamically without trapping to EL3 firmware

- Introduce COMPAT_SIGMINSTKSZ for use in compat_sys_sigaltstack

- Optimise emulation of MRS instructions to ID_* registers on ARMv8.4

- Support for Common Not Private (CnP) translations allowing threads of
  the same CPU to share the TLB entries

- Accelerated crc32 routines

- Move swapper_pg_dir to the rodata section

- Trap WFI instruction executed in user space

- ARM erratum 1188874 workaround (arch_timer)

- Miscellaneous fixes and clean-ups
