Ah ok, I thought you wasn't interested in doing this anymore :).

My main intention was to have all those in a single struct and use a
single store_bit/show_bit function.

Sure, you can do bools but this'll still be single variables spread
around in mce.c instead of one single struct mca_config which nicely
encapsulates all the configuration we do in the MCA code.

Or, you can modify the mca_config I have there and use bools and pass a
pointer to each actual bool member in each DEVICE_BIT_ATTR invocation
(and rename it to DEVICE_BOOL_ATTR). Yeah, that could work, unless I'm
missing something else, of course.

Thanks.
