Subject: [PATCH 1/4] powerpc: Remove Cell-specific relocation-on interrupt vector code
Date: Tue, 05 Feb 2013 04:09:40 +0000	[thread overview]
Message-ID: <20130205040940.GB20303@drongo> (raw)
In-Reply-To: <20130205040902.GA20303@drongo>

The Cell processor doesn't support relocation-on interrupts, so we
don't need relocation-on versions of the interrupt vectors that are
purely Cell-specific.  This removes them.
