Subject: [patch 5/8] x86: apic - get rid of local_apic_timer_verify_ok
Date: Thu, 01 Jan 1970 03:00:05 +0300	[thread overview]
Message-ID: <20080814184652.022151205@gmail.com> (raw)
In-Reply-To: 20080814183428.550709025@gmail.com

[-- Attachment #1: x86-apic-get-rid-of-local_apic_timer_verify_ok.patch --]
[-- Type: text/plain, Size: 1775 bytes --]

We are able to use clock_event_device as it's done in
64bit apic code so lets get rid of local_apic_timer_verify_ok
variable.
