Subject: [PATCH 4/5] KVM: arm64: ptdump: Test PMD_TYPE_MASK for block mapping
Date: Sat, 5 Oct 2024 18:08:23 +0530 [thread overview]
Message-ID: <20241005123824.1366397-5-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20241005123824.1366397-1-anshuman.khandual@arm.com>
This changes stage-2 ptdump making it test given page table entries against
PMD_TYPE_SECT on PMD_TYPE_MASK bits for a block mapping, as is the case for
stage-1 ptdump.
