From 0cbb613fa82fb09b6ef914ab0aaa92091f367bb6 Mon Sep 17 00:00:00 2001 From: Seth Jennings Date: Mon, 13 Feb 2012 08:47:49 -0600 Subject: [PATCH] staging: fix powerpc linux-next break on zsmalloc linux/vmalloc.h added to zsmalloc-main.c to resolve implicit declaration errors. X86 dependency added to zsmalloc and dependent drivers zcache and zram. This X86 only requirement is not ideal. Working to find portable functions for __flush_tlb_one and set_pte.
