The patch titled
Subject: SM501: Align PANEL fb to PAGE_SIZE
has been removed from the -mm tree. Its filename was
sm501-fixup-allocation-code-to-be-64bit-resource-compliant-sm501-align-panel-fb-to-page_size.patch
This patch was dropped because it was folded into sm501-fixup-allocation-code-to-be-64bit-resource-compliant.patch

Subject: Subject: SM501: Align PANEL fb to PAGE_SIZE
From: Ben Dooks <ben-linux@xxxxxxxxx>
Some programs, such as anything linked with directfb get the drawing wrong
if given an screen start which is not aligned to PAGE_SIZE. Change the
allocator to always return an properly aligned address when asked for
PANEL memory.
