From: Helge Deller Subject: [PATCH] parisc: Increase default initial kernel mapping to 32 MB Date: Sat, 8 Oct 2016 16:16:49 +0200 Message-ID: <20161008141649.GA31592@p100.box> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: linux-parisc@vger.kernel.org, James Bottomley , John David Anglin Return-path: List-ID: List-Id: linux-parisc.vger.kernel.org For 32-bit kernels which include multiple modules built-in 16 MB initial kernel mapping may get too small. To avoid boot problems increase the kernel mapping to 32 MB for all 32- and 64-bit kernel configs.
