From ca0ad83da17b6ba07f9eb5902e69daac90c4fa61 Mon Sep 17 00:00:00 2001 From: John David Anglin Date: Sat, 20 Apr 2013 19:41:06 +0000 Subject: parisc: Provide __ucmpdi2 to resolve undefined references in 32 bit builds. The Debian experimental linux source package (3.8.5-1) build fails with the following errors: ... MODPOST 2016 modules ERROR: "__ucmpdi2" [fs/btrfs/btrfs.ko] undefined! ERROR: "__ucmpdi2" [drivers/md/dm-verity.ko] undefined! The attached patch resolves this problem. It is based on the s390 implementation of ucmpdi2.c. Signed-off-by: John David Anglin Cc: "James E.J.
