There is a read(), and a vread() did you modify the slow syscall path to

I miss type, read().
John mentioned that he thought fsys_mmio_ptr could be held in the vread
pointer. vread() is used in x86 for vsyscalls. It looks like you've used
the update_vsyscall() which is also used for vsyscalls. So vread could
also be used .. Have you considered that at all?
No, but yes it can be done, overloading the meaning.
It would need to change in the future if vread was needed.
I have no strong argument against using it.
Although we may still need the IA64 define, I removed 32bit read mmio and
if that is brought back the fast syscall patch call will need to have a
field in the
clocksource struct that would indicated that. Waiting on comments about
that...
John and discuss this awhile back felt it was not needed, may prove wrong.
