Subject: [PATCH] Exclude PUD/PMD alloc functions if !MMU
Date: Tue, 04 Jan 2005 19:56:28 +0000 [thread overview]
Message-ID: <17892.1104868588@redhat.com> (raw)
Don't declare pud_alloc() and pmd_alloc() if a nommu kernel is being
compiled. These functions require various things that aren't defined for
nommu.
