[PATCH] ia64: eliminate softlockup warning

Fix an unnecessary softlockup watchdog warning in the ia64
uncached_build_memmap() that occurs occasionally at 256p and always at
512p. The problem occurs at boot time.

It would be good if we had a cleaner mechanism to temporarily silence
the watchdog thread, e.g.,
http://marc.theaimsgroup.com/?l=linux-kernel&m\x111552476401175&w=2
but until that patch gets merged, this fix will have to suffice.
