From d88262623fb58853ed60fb110141c435de26e3de Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 26 Oct 2010 14:22:30 -0700 Subject: [PATCH] vmlinux.lds.h: lower init ramfs alignment to 4 The new init ramfs format (cpio based) requires an alignment of 4 (per the documentation and per the source files themselves). As for compressed sources, the decompressors can all deal with unaligned buffers. The cpio source is also found in the __init sections of the kernel, so once they are read and expanded into a tmpfs, the source is freed. That means there is no need to force page alignment here either. This has been used on Blackfin systems for many releases without issue.
