OK, attached is the set of patches by far. Based on them, now I can
enable grant table and also a small xenstore test in dom0 succeeds.
However the root device still can't be located:
Running on Xen! flags=0x0
xen-event-channel using irq 233
grant table at e000010000000000
after gnttab_resume
Grant table initialized
Xen virtual console successfully installed as tty0
Event-channel device installed.
xen_blk: Initialising virtual block device driver
(Seems the blkback and blkfront still no connection yet!!!)

VFS: Cannot open root device "hda1" or unknown-block(0,0)
