    Subject[PATCH] vmlinux.lds.h: lower init ramfs alignment to 4
    Date
    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.
