Subject: [PATCH 1/7] powerpc/85xx: re-enable timebase sync disabled by KEXEC patch
Date: Fri, 3 Dec 2010 20:34:05 +0800 [thread overview]
Message-ID: <1291379651-8822-1-git-send-email-leoli@freescale.com> (raw)
The timebase sync is not only necessary when using KEXEC. It should also
be used by normal boot up and cpu hotplug. Remove the ifdef added by
the KEXEC patch. Fix a problem that cpu hotplugging freezes the whole system.
