Hi,

[...]

Why can't they be in drivers/busfreq? Create a subdirectory for
platform-specific subdrivers if needed, but they definitiely do NOT
belong in drivers/misc, and there seems to be little reason to have them
in arch/arm.

Myungjoo, can you please indicate your preference with respect to where
I should place the PPMU driver. I'll re-work based on that.
