Hi,

I need to find the points where we enters into hypercall (for all the
hypercalls) execution and from where we come out... from what i have
understood entry-point is
somewhere in arch/x86/x86_32/entry.S ...but  exactly where and what about
exit point?

hypercall_page. The arch/x86/include/asm/xen/hypercall.h has the macros
for it.

When we come back it usually right after the call.
