Subject: [PATCH] Fix 64 bit addressing support for GEM
This patch adds support for 32 bit GEM in
64 bit system. It checks capability at runtime
and uses appropriate buffer descriptor.

#ifdef CONFIG_ARCH_DMA_ADDR_T_64BIT
- if (GEM_BFEXT(DBWDEF, gem_readl(bp, DCFG1)) > GEM_DBW32)
+ if (GEM_BFEXT(DAW64, gem_readl(bp, DCFG6))) {
+ pr_emerg("rozieblo: 64B!\n");I forgot to remove that log message.
