Subject: [PATCH 04/12] KVM: arm64: Allocate stage-2 pgd pages with GFP_KERNEL_ACCOUNT
Date: Fri, 30 Oct 2020 16:40:09 +0000	[thread overview]
Message-ID: <20201030164017.244287-5-maz@kernel.org> (raw)
In-Reply-To: <20201030164017.244287-1-maz@kernel.org>

From: Will Deacon <will@kernel.org>

For consistency with the rest of the stage-2 page-table page allocations
(performing using a kvm_mmu_memory_cache), ensure that __GFP_ACCOUNT is
included in the GFP flags for the PGD pages.
