From mboxrd@z Thu Jan 1 00:00:00 1970 From: Keith Owens Date: Fri, 12 Sep 2003 02:25:52 +0000 Subject: [patch] 2.4.22-ia64-030909 build of offsets.h Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org 2.4.22 deleted include/asm-ia64/offsets.h from the kernel tree. If there is no other copy of that file on the include paths (say for cross compiling) then make dep breaks, offsets.h is required before you can build offsets.h.
