Subject: Revert "KVM: MMU: make kvm_mmu_reset_context() flush the guest TLB"
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f8f7e5ee1037e347eafff8f526913b92cec54873;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Revert "KVM: MMU: make kvm_mmu_reset_context() flush the guest TLB"

This reverts commit bee931d31e588b8eb86b7edee32fac2d16930cd7.

TLB flush should be done lazily during guest entry, in
kvm_mmu_load().
