Date: Thu, 28 Jul 2011 16:54:52 +0100 From: David Howells <dhowells@...hat.com> To: torvalds@...l.org Cc: linux-kernel@...r.kernel.org, linux-kbuild@...r.kernel.org, David Howells <dhowells@...hat.com> Subject: [PATCH 35/40] UAPI: Set up uapi/asm/Kbuild.asm [ver #3] Set up uapi/asm/Kbuild.asm. This requires the mandatory headers to be dynamically detected. The same goes for include/asm/Kbuild.asm. The problem is that the header files will be split or moved one at a time, but each header file in Kbuild.asm's list applies to all arch headers of that name simultaneously. The dynamic detection of mandatory files can be undone later.
