From 7c51714e0ad7b5009c80b14e6504a6eef9f639e8 Mon Sep 17 00:00:00 2001 From: Sean Bruno Date: Mon, 22 Sep 2014 05:07:22 +0000 Subject: [PATCH] svn revisions r269964 and r269963 seemed to have impaired small memory footprint systems(32M/64M) and didn't leave enough free memory to load modules when it was setting up page tables that for sizes that are never used on these smallish boards. Set kmem_zmax to PAGE_SIZE on these smaller systems (< 128M) to keep this from happening. Verified on mips32 h/w.
