That would be better if it's not too much trouble. A patch with a title of "Make some functions static" shouldn't really be deleting functions entirely. cheers

Since these functions can be made static, make it so. While doing so, it turns out that holly_power_off and holly_halt are unused, so remove them. I would have said 'since these functions are only used in this C file, make them static'.

[PATCH] powerpc: Make some functions static
In commit cb9e4d10c448 ("[POWERPC] Add support for 750CL Holly board") new functions were added. Since these functions can be made static, make it so. While doing so, it turns out that holly_power_off and holly_halt are unused, so remove them.
