Subject: [PATCH 12/28] UML - x86-64 headers
Date: Mon, 10 Jan 2005 02:35:41 -0500 [thread overview]
Message-ID: <200501100735.j0A7ZfPW005790@ccure.user-mode-linux.org> (raw)
Add a bunch of headers to include/asm-um to support x86_64.
Also move some arch-specific things from generic files to x86-specific ones.
