From 67296874eb1cc80317bf2a8fba22b494e21eb29b Mon Sep 17 00:00:00 2001 From: Olav Haugan Date: Fri, 22 Nov 2013 09:30:41 -0800 Subject: [PATCH] staging: zsmalloc: Ensure handle is never 0 on success zsmalloc encodes a handle using the pfn and an object index. On hardware platforms with physical memory starting at 0x0 the pfn can be 0. This causes the encoded handle to be 0 and is incorrectly interpreted as an allocation failure. This issue affects all current and future SoCs with physical memory starting at 0x0. All MSM8974 SoCs which includes Google Nexus 5 devices are affected. To prevent this false error we ensure that the encoded handle will not be 0 when allocation succeeds.
