Hi folks,

This matches big pcluster kernel support in for-next. I've tested
together with ro_fsstress and aosp x86_64 cuttlefish boot without
any problem.

XXX: since LZMA hasn't been introduced yet, compression cfg
generation code is still a preliminary version, will refine it
with later formal LZMA support.

Thanks,
Gao Xiang
