[PATCH 04/12] KVM: arm64: Allocate stage-2 pgd pages with GFP_KERNEL_ACCOUNT

[Marc Zyngier]

From: Will Deacon <will at 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.
