Subject: [PATCH 2/3 v2] powerpc/mpic: Use the MPIC_LARGE_VECTORS flag for FSL MPIC.
Date: Sun, 3 Jun 2012 13:13:20 +0530 [thread overview]
Message-ID: <1338709400-31191-1-git-send-email-Varun.Sethi@freescale.com> (raw)
We should use the MPIC_LARG_VECTORS flag while intializing the MPIC.
This prevents us from eating in to hardware vector number space (MSIs)
while setting up internal sources.
