Subject: [PATCH 19/34] target/i386/mshv: expose msvh_get_generic_regs
Date: Fri, 17 Apr 2026 12:56:03 +0200	[thread overview]
Message-ID: <20260417105618.3621-20-magnuskulke@linux.microsoft.com> (raw)
In-Reply-To: <20260417105618.3621-1-magnuskulke@linux.microsoft.com>

We expose the fn, so we can call them from the other source files
(msr.c).
