Use GFP_KERNEL_ACCOUNT instead of GFP_KERNEL when allocating pages for the the GPA page tables. The primary motivation for accounting the allocations is to align with the common KVM memory cache helpers in preparation for moving to the common implementation in a future patch. The actual accounting is a bonus side effect. Signed-off-by: Sean Christopherson <redacted> --- arch/mips/kvm/mmu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
