Hi Alain,

Looking pretty good now.  The only issues that I see so far are:

- Putting the kernel compression selection in init/Kconfig isn't going
  to work too well, since it affects all architectures, and not all
  architectures even do their own decompression (for quite a few
  architectures it's the boot loader's responsibility.)

  I see two options here: either have this be parameterized by the arch
  Kconfig files, or simply move this chunk into arch/*/Kconfig as part
  of the arch-enablement patches.  The latter is probably the simplest,
  even if it means some replicated code.

  Let me know what you think -- I can do this pretty easily while
  importing, so you don't need to submit a full new patchset.

- I did a followon patch (attached) to change the ramdisk compression
  search to table driven.  Since I already did the followon patch, don't
  worry about it.
