I was going to do it the other way around - wait until this patch is merged, and then update some code to use it.  After all, it's easier to use a macro if it already exists in a header file. :-)

Grepping for "while.*in_be" finds lots of candidates.

I was originally planning to use this macro in sound/soc/fsl/fsl_ssi.c, but I eliminated the need to poll on a register with commit a4d11fe50c238a7da5225d1399314c3505cbd792 ("ASoC: remove trigger delay in Freescale MPC8610 sound driver").  So now I need to find a new guinea pig.
