NAK to this patch.
The greater concern is WTF are cleanup patches for the ARM architecture
going via the sound tree. Especially patches which I have concerns about.

that you've investigated whether it causes the compiler to mis-optimise
the code.
Takashi - please remove all such patches from the sound tree. They
