Subject: [PATCH v2 17/18] powerpc/book3e-64/kexec: Set "r4 = 0" when entering spinloop
Date: Tue, 6 Oct 2015 22:48:21 -0500 [thread overview]
Message-ID: <1444189702-17241-18-git-send-email-scottwood@freescale.com> (raw)
In-Reply-To: <1444189702-17241-1-git-send-email-scottwood@freescale.com>
book3e_secondary_core_init will only create a TLB entry if r4 = 0,
so do so.
