        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau

I'm using Gentoo, nouveau overlay.  Kernel is 2.6.29-rc7-git1.  The Gentoo
ebuild pulls x11-drm source from git.  I'm on powerpc.

I get this error:
  CC [M] 
/var/tmp/portage/x11-base/x11-drm-99999999/work/drm/linux-core/nouveau_state.o
/var/tmp/portage/x11-base/x11-drm-99999999/work/drm/linux-core/nouveau_state.c:
In function 'nouveau_load':
/var/tmp/portage/x11-base/x11-drm-99999999/work/drm/linux-core/nouveau_state.c:499:

make[2]: ***

Error 1

make: *** [modules] Error 2

If I change "___swab32" to "__fswab32" this compiles, as per
#nouveau on irc.

Created an attachment (id=24923)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=24923)
Change ___swab32 to __swab32 and fix build on powerpc

I had same problem on powerpc(Debian) with kernel 2.6.29.1. I made as David did
and it build.

The swab32 function is not used anymore/currently in the nouveau DRM. Closing
as fixed.

If there are build problems with the Nouveau kernel tree, file a new bug,
please.
