[PATCH v2 2/6] KVM: VMX: Move PLE grow/shrink helpers above vmx_vcpu_load()

Wed May 22 11:40:09 AEST 2024
Move VMX's {grow,shrink}_ple_window() above vmx_vcpu_load() in preparation
of moving the sched_in logic, which handles shrinking the PLE window, into
vmx_vcpu_load().
No functional change intended.
