Use BIT(cpu) here. And you should run scripts/checkpatch.pl on your
patches before sending them.


For the record:

$ scripts/checkpatch.pl --strict allwinner.patch
total: 0 errors, 0 warnings, 0 checks, 527 lines checked

allwinner.patch has no obvious style problems and is ready for submission.

This is on top of "v3.12-rc1-336-gd8524ae".

checkpatch.pl does not complain as long as the number of spaces before
and after an operator is the same. There is a patch pending to change
this with the --strict option, but it will still not complain in 'normal'
operation.
