Tmanager generates tag to build kernel when branch specified.
The tag starts with x86, which leads to the build process failing
to parse the tag.
Modify the generate-rpms.sh to support building with "x86-*" tags.

it could help system reclaim more free memory when the applications
have consumed too much memory. So we introduce the ZRAM by kernel
modules, user could insmod it as needed.

This option enables a transparent branch optimization that
makes certain almost-always-true or almost-always-false branch
conditions even cheaper to execute within the kernel.
CONFIG_BLK_DEV_RAM=y will create /dev/ram* by default which is unneeded,
just make it a module, ram block devices can still be created with
modprobe.
