Subject: [PATCH v3 13/17] powerpc/book3e-64: Don't limit paca to 256 MiB
Date: Mon, 19 Oct 2015 17:10:18 -0500 [thread overview]
Message-ID: <1445292618-20418-1-git-send-email-scottwood@freescale.com> (raw)
In-Reply-To: <1444189702-17241-14-git-send-email-scottwood@freescale.com>
This limit only makes sense on book3s, and on book3e it can cause
problems with kdump if we don't have any memory under 256 MiB.
