From bc87aec39399f5dbcb83eb3ebbce0b0beb57e893 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Fri, 29 May 2026 15:21:57 -0700 Subject: [PATCH] KVM: x86: Move async #PF helpers to x86.h (as inlines) Move kvm_pv_async_pf_enabled() and kvm_async_pf_hash_reset() to x86.h in anticipation of extracting the majority of register and MSR specific code out of x86.c. No functional change intended.
