Merge tag 'kvm-x86-fixes-6.18-rc5' of https://github.com/kvm-x86/linux into HEAD

KVM x86 fixes for 6.18:

 - Inject #UD if the guest attempts to execute SEAMCALL or TDCALL as KVM
   doesn't support virtualization the instructions, but the instructions
   are gated only by VMXON, i.e. will VM-Exit instead of taking a #UD and
   thus result in KVM exiting to userspace with an emulation error.

 - Unload the "FPU" when emulating INIT of XSTATE features if and only if
   the FPU is actually loaded, instead of trying to predict when KVM will
   emulate an INIT (CET support missed the MP_STATE path).  Add sanity
   checks to detect and harden against similar bugs in the future.

 - Unregister KVM's GALog notifier (for AVIC) when kvm-amd.ko is unloaded.

 - Use a raw spinlock for svm->ir_list_lock as the lock is taken during
   schedule(), and "normal" spinlocks are sleepable locks when PREEMPT_RT=y.

 - Remove guest_memfd bindings on memslot deletion when a gmem file is dying
   to fix a use-after-free race found by syzkaller.

 - Fix a goof in the EPT Violation handler where KVM checks the wrong
   variable when determining if the reported GVA is valid.
