Series KVM: TDX: Cleanup the kvm_x86_ops structure for vmx/tdx | expand

Commit Message

Verma, Vishal L March 18, 2025, 6:35 a.m. UTC 
In preparation for a cleanup of the x86_ops struct for TDX, which turns
several of the ops definitions to macros, move the
vt_apicv_pre_state_restore() helper into posted_intr.c.

Based on a patch by Sean Christopherson <seanjc@google.com>
