| From | Sean Christopherson <> | Subject | [PATCH v2 16/45] KVM: MIPS: Use kvm_vcpu_cache to allocate vCPUs | Date | Wed, 18 Dec 2019 13:55:01 -0800 |
| |
For reasons unknown, MIPS configures the vCPU allocation cache but allocates vCPUs via kzalloc(). Allocate from the vCPU cache in preparation for moving vCPU allocation to common KVM code.
