Subject: [PATCH 0/2] x86/head/64: Mark the code as __head in mem_encrypt_identity.c
Date: Tue, 17 Oct 2023 15:08:05 +0800	[thread overview]
Message-ID: <cover.1697525407.git.houwenlong.hwl@antgroup.com> (raw)

Similar to head64.c, mark all the code in mem_encrypt_identity.c as
__head since it runs in the identity address. This is part of the
patchset that builds the head code as PIE[1].
