From f691fa1080c37c48da0cdfeae082c3bef5df2643 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 30 Mar 2015 14:10:37 +1100 Subject: powerpc: Replace mem_init_done with slab_is_available() We have a powerpc specific global called mem_init_done which is "set on boot once kmalloc can be called". But that's not *quite* true. We set it at the bottom of mem_init(), and rely on the fact that mm_init() calls kmem_cache_init() immediately after that, and nothing is running in parallel. So replace it with the generic and 100% correct slab_is_available().
