  • Some callers don't use it so make it optional.

  • The comments of find_cpio_data() says:

    * @offset: When a matching file is found, this is the offset to the
    * beginning of the cpio. ......

    But according to the code,

    dptr = PTR_ALIGN(p + ch[C_NAMESIZE], 4);
    nptr = PTR_ALIGN(dptr + ch[C_FILESIZE], 4);
    ....
    *offset = (long)nptr - (long)data; /* data is the cpio file */

    @offset is the offset of the next file, not the matching file itself.
    This is confused and may cause unnecessary waste of time to debug.
    So fix it.

    As Tejun Heo suggested, rename @offset to @nextoff which is more clear
    to users. And also adjust the new comments.

  • The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    This removes all the uses of the __cpuinit macros from C files in
    the core kernel directories (kernel, init, lib, mm, and include)
    that don't really have a specific maintainer.

  • Add a simple cpio decoder without library dependencies for the purpose
    of extracting components from the initramfs blob for early kernel
    uses. Intended consumers so far are microcode and ACPI override.
