Subject: [POWERPC] PS3: Map SPU regions as non-guarded
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=53f7c5453dfd3ba66a2d80bd2fda98a2438c3dc0;p=deliverable%2Flinux.git

[POWERPC] PS3: Map SPU regions as non-guarded

Use ioremap_flags() to map SPU regions as non-guarded.
Change the use of _ioremap() to ioremap_flags().
