Subject: [PATCH 12/13] spufs: fix allocation on 64k pages
Date: Wed, 04 Jan 2006 20:31:32 +0100 [thread overview]
Message-ID: <20060104194502.080544000@localhost> (raw)
In-Reply-To: 20060104193120.050539000@localhost
[-- Attachment #1: spufs-64k-page.diff --]
[-- Type: text/plain, Size: 746 bytes --]
The size of the local store is architecture defined
and independent from the page size, so it should
not be defined in terms of pages in the first place.
This mistake broke a few places when building for
64kb pages.
