Subject: [patch] 2.6.1-mm5 compile do not use shared extable code for ia64
Date: Tue, 20 Jan 2004 12:23:49 +0000 [thread overview]
Message-ID: <E1Aiuv7-0001cS-00@jaguar.mkp.net> (raw)
Hi,
The new sort_extable and shares search_extable code doesn't work on
ia64. I have introduced two new #defines that archs can define to avoid
the common code being built. ARCH_HAS_SEARCH_EXTABLE and
ARCH_HAS_SORT_EXTABLE.
With this patch, 2.6.1-mm5 builds again on ia64.
Cheers,
Jes
