Subject: [PATCH kvmtool v3 03/17] Update psci.h to Linux 6.5-rc1
Date: Wed,  2 Aug 2023 23:42:41 +0000	[thread overview]
Message-ID: <20230802234255.466782-4-oliver.upton@linux.dev> (raw)
In-Reply-To: <20230802234255.466782-1-oliver.upton@linux.dev>

In order to do PSCI emulation in kvmtool, we're going to need to pull in
a few more definitions.
