Subject: [PATCH V2 1/5] KVM: SVM: Move STGI and CLGI intercept handling
Date: Mon, 12 Jan 2026 17:45:31 +0000	[thread overview]
Message-ID: <20260112174535.3132800-2-chengkev@google.com> (raw)
In-Reply-To: <20260112174535.3132800-1-chengkev@google.com>

Similar to VMLOAD/VMSAVE intercept handling, move the STGI/CLGI
intercept handling to svm_recalc_instruction_intercepts().
