From e3b6a02816ebbda3acfde2f079446ba92c97e70b Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 11 Oct 2016 20:40:02 +0200 Subject: parisc: Zero-initialize newly alloced memblock Commit 4fe9e1d957e4 ("parisc: Drop bootmem and switch to memblock") switched to the memblock allocator, but missed to zero-initialize the newly allocated memblocks. This lead to crashes on some machines like the rp3410.
