From 6c5da7aced798c7781f054a76c769b85f0173561 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 30 Sep 2008 19:31:44 +0100 Subject: [ARM] mm: move vmalloc= parsing to arch/arm/mm/mmu.c There's no point scattering this around the tree, the parsing of the parameter might as well live beside the code which uses it. That also means we can make vmalloc_reserve a static variable.
