From d95abbbb291bf5bce078148f53603ce9c0aa1d44 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 27 Mar 2013 01:43:14 +0100 Subject: staging: zsmalloc: Fix link error on ARM Testing the arm chromebook config against the upstream kernel produces a linker error for the zsmalloc module from staging. The symbol flush_tlb_kernel_range is not available there. Fix this by removing the reimplementation of unmap_kernel_range in the zsmalloc module and using the function directly. The unmap_kernel_range function is not usable by modules, so also disallow building the driver as a module for now.
