  KVM: arm64: Set HCR_EL2.PTW to prevent AT taking synchronous exception (2020-08-28 15:27:47 +0100)

----------------------------------------------------------------
- Fix kernel build with the integrated LLVM assembler which doesn't
  see the -Wa,-march option.

- Fix "make vdso_install" when COMPAT_VDSO is disabled.

- Make KVM more robust if the AT S1E1R instruction triggers an exception
  (architecture corner cases).

----------------------------------------------------------------
