svn commit: r263248 - head/sys/ia64/ia64

[Marcel Moolenaar]

Author: marcel
Date: Sun Mar 16 20:21:40 2014
New Revision: 263248
URL: http://svnweb.freebsd.org/changeset/base/263248

Log:
  In intr_event_handle() we already save and set td_intr_frame, so
  don't do it also in ia64_handle_intr(). With ia64_handle_intr()
  not saving and setting td_intr_frame, make sure to do it for
  clock interrupts in ia64_ih_clock().
