- paravirtualize fsys call (fsys.S) by multi compile
- paravirtualize gate page (gate.S) by multi compile
- support save/restore
For this purpose, the followings needs to be paravirtualized
- ar.itc instruction

probably xend serializes creating domains, so it hasn't
been caused issues.

Hi. This patch itself looks okay.
Just for confirming. This patch doesn't affect the
result because the following line sees only the lsb 0 bit
of r18. Correct?
extr.u r18=r16,XEN_VIRT_UC_BIT, 15// extract UC bit
...
dep r19=r18,r19,4,1 // set bit 4 (uncached) if the access was to UC r
applied, thanks.

pv_cpu_ops.getreg(_IA64_REG_IP) returned constant.
But the returned ip valued should be the one in the caller, not of the callee.
This patch fixes that.

What is the point to remove it from the minios?

Add two hooks, paravirt_get_fsyscall_table() and
paravirt_get_fsys_bubble_doen() to paravirtualize fsyscall implementation.
This patch just add the hooks fsyscall and don't paravirtualize it.
