[PATCH 0/2] x86/head/64: Mark the code as __head in mem_encrypt_identity.c

Posted by Hou Wenlong 2 years, 2 months ago

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].
