You are right, this should not be MIPS specific config.
This patch will be omitted in the next version.

Thanks!

Kind regards,
Miodrag

Why is this a MIPS config file?  What about the "generic" android
configs we already have?  Shouldn't they work just as well here?

And finally, does this config file fragment pass the latest tests that
Google has for kernel config requirements?
