Subject: [PATCH] powerpc/85xx: Fix doorbells
Date: Tue, 11 Oct 2011 19:06:42 -0500 [thread overview]
Message-ID: <1318378002-32531-1-git-send-email-msm@freescale.com> (raw)
Commit 765342526246c97600e5344c0949824d94bb51c3 made some small
changes to IPI, message_pass in smp_ops was initialized to NULL
for other platforms but not for 85xx which causes us to always
use the mpic for IPI's. This patch makes doorbells work again.
