Subject: [PATCH] KVM: x86/pmu: Use wrmsrq() instead of the deprecated wrmsrl() alias
Date: Thu, 25 Jun 2026 17:00:57 +0800	[thread overview]
Message-ID: <20260625090057.4864-1-likexu@tencent.com> (raw)

Replace the remaining wrmsrl() calls in the x86 vPMU code with the
canonical wrmsrq() helper, for consistency with the surrounding code
that already uses the q-suffixed form.

wrmsrl() is merely a compatibility wrapper that expands directly to
wrmsrq() as part of the ongoing treewide rename to the q-suffixed MSR
helpers, so the generated code is identical.

No functional change intended.
