Subject: [PATCH 08/17] kvm-arm: arm: Introduce hyp page table empty checks
Date: Mon, 4 Apr 2016 17:26:08 +0100 [thread overview]
Message-ID: <1459787177-12767-9-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1459787177-12767-1-git-send-email-suzuki.poulose@arm.com>
Introduce hyp_pxx_table_empty helpers for checking whether
a given table entry is empty. This will be used explicitly
once we switch to explicit routines for hyp page table walk.
