public/acm.h defines both an ACM_DEBUG flag and a printkd function that, if ACM_DEBUG is defined will convert to a printk. public/acm.h is included by userspace applications where printk isn't necessarily meaningful. Furthermore, it appears ACM_DEBUG is only used within Xen anyway so making it apart of the public headers doesn't make much sense.

Therefore, I'd like to move ACM_DEBUG and printkd into acm/acm_core.h. While at it, it seems like a good idea to change the printkd into either one of the existing Xen debug macros or to get rid of it altogether.

I wanted to check first to see if there was an emerging standard macro (a quick glance shows printk, DPRINTK, PRINT, and I'm sure there are at least a few more). Recommendations are appreciated.

If they are debug printk's then they should map onto DPRINTK. The PRINT macro is specific to debugging within the SEDF scheduler.
