Subject: [PATCH 1/3] KVM: x86/mmu: Rename reset_rsvds_bits_mask()
Date: Tue, 19 Apr 2022 23:17:02 +1200	[thread overview]
Message-ID: <efdc174b85d55598880064b8bf09245d3791031d.1650363789.git.kai.huang@intel.com> (raw)
In-Reply-To: <cover.1650363789.git.kai.huang@intel.com>

Rename reset_rsvds_bits_mask() to reset_guest_rsvds_bits_mask() to make
it clearer that it resets the reserved bits check for guest's page table
entries.
