Subject: [PATCH v2 0/2] Fix and add warning of misuse of type##_replace_bits()

By inspection there is one mistake in the use of u64_replace_bits(). Fix
this and while I'm here add a __must_check annotation to help avoid the
same mistake happening again.

Changes since v1:

Patch 1: Add Rb tag from Zenghui Yu - thanks!
Patch 2: Extend to add __must_check on _get_bits() and _encode_bits()

Ben Horgan (2):
  KVM: arm64: Fix enforcement of upper bound on MDCR_EL2.HPMN
  bitfield: Ensure the return values of helper functions are checked
