Subject: [PATCH] powerpc/book3e: Fix CPU feature handling on e5500 in 32-bit mode
Date: Thu, 2 Jun 2011 15:52:01 -0500 [thread overview]
Message-ID: <1307047921-4784-1-git-send-email-galak@kernel.crashing.org> (raw)
We are missing FPU feature bit that user space may require. In the
64-bit mode this gets set since we pull it in via COMMON_USER_PPC64. We
just explicity set it so user space will be happy again.
