Subject: [PATCH 3/5] sparc64: use PAGE_SIZE in vmlinux.lds
Date: Thu, 24 May 2007 22:13:11 +0200 [thread overview]
Message-ID: <20070524201311.GE1109@uranus.ravnborg.org> (raw)
In-Reply-To: <20070524200440.GA1109@uranus.ravnborg.org>
sparc64 had hardcoded pagesize to 8192 for alignment.
But optimal alignment is PAGE_SIZE so replace harcoded values
with the PAGE_SIZE constant.
Note: PAGE_SIZE differ with configuration so this is a change
in functionality - see page.h
