battery information from EC sometimes. After several retries, the
operation will work. This patch is to retry to get battery information 5
times if the first try fails.

drm/radeon: stop poisoning the GART TLB 2014-07-17T22:39:50+00:00 Christian König christian.koenig@amd.com 2014-06-04T13:29:56+00:00 fa1bd9b16b3432bce7937a5a4b5d75ab2f5b634c commit 0986c1a55ca64b44ee126a2f719a6e9f28cbe0ed upstream. When we set the valid bit on invalid GART entries they are loaded into the TLB when an adjacent entry is loaded. This poisons the TLB with invalid entries which are sometimes not correctly removed on TLB flush. For stable inclusion the patch probably needs to be modified a bit.
