KVM: ia64: fix GVMM module including position-dependent objects
The GVMM module is position independent since it is relocated to the guest
address space.

Commit ea696f9cf ("ia64 kvm fixes for O=... builds") broke this by linking
GVMM with non-PIC objects.

Fix by creating two files: memset.S and memcpy.S which just include the files
under arch/ia64/lib/{memset.S, memcpy.S} respectively.

[akpm: don't delete files which we need]

rename div64_64 to div64_u64
Rename div64_64 to div64_u64 to make it consistent with the other divide
functions, so it clearly includes the type of the divide.  Move its definition
to math64.h as currently no architecture overrides the generic implementation.
 They can still override it of course, but the duplicated declarations are
avoided.

KVM: hlt emulation should take in-kernel APIC/PIT timers into account
Timers that fire between guest hlt and vcpu_block's add_wait_queue() are
ignored, possibly resulting in hangs.

Also make sure that atomic_inc and waitqueue_active tests happen in the
specified order, otherwise the following race is open:

CPU0                                        CPU1
                                            if (waitqueue_active(wq))
add_wait_queue()
if (!atomic_read(pit_timer->pending))
    schedule()
                                            atomic_inc(pit_timer->pending)
