Change ___swab32 to __swab32 and fix build on powerpc none

Description David 2009-03-08 17:57:43 UTC 
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: error: implicit declaration of function '___swab32'
make[2]: *** [/var/tmp/portage/x11-base/x11-drm-99999999/work/drm/linux-core/nouveau_state.o] Error 1

make[1]: Leaving directory `/usr/src/linux-2.6.29-rc7-git1'
make: *** [modules] Error 2

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

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.
