Subject: [PATCH] KVM: arm64: Allocate stage-2 pgd pages with GFP_KERNEL_ACCOUNT
Date: Mon, 26 Oct 2020 14:44:23 +0000	[thread overview]
Message-ID: <20201026144423.24683-1-will@kernel.org> (raw)

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.
