[PATCH 01/14] x86, boot: align the .bss section in the decompressor

From: H. Peter Anvin
Date: Thu May 07 2009 - 18:27:41 EST


From: H. Peter Anvin <hpa@xxxxxxxxx>

Aligning the .bss section makes it trivially faster, and makes using
larger transfers for the clear slightly easier.

[ Impact: trivial performance enhancement, future patch prep ]
