powerpc/eeh: Fix /proc/ppc64/eeh creation
Thadeu Lima de Souza Cascardo [Fri, 26 Aug 2011 10:36:31 +0000 (10:36 +0000)]
commit 8feaa43494cee5e938fd5a57b9e9bf1c827e6ccd upstream.

Since commit 188917e183cf9ad0374b571006d0fc6d48a7f447, /proc/ppc64 is a
symlink to /proc/powerpc/. That means that creating /proc/ppc64/eeh will
end up with a unaccessible file, that is not listed under /proc/powerpc/
and, then, not listed under /proc/ppc64/.

Creating /proc/powerpc/eeh fixes that problem and maintain the
compatibility intended with the ppc64 symlink.
