This set of patches modifies the debug system by replacing some
complicated macros with the equivalent operations in C. Then, the
COMP_XX component debugging is converted into a debug mask. Finally,
code is added to permit setting the debug mask from sysfs.

These two debugging formss implement debugging using rather complicated
macro constructions. These are replaced with compiled code that is easier
to understand.

Kalle,
I was not aware of that part of sysfs. I will respin the patch as well as remove
the old code that set the debug level.
Thanks,
Larry

Good, thanks. I dropped the whole series now and assume that you will
send v2.

The debugging macros contain a parameter COMP_XX that could be used as a
mask; however, the code turns all these various bits on at the same time.
This change implements them as a proper mask, and adds module parameters
to set the mask at load time.

The previous commit changes the debug system to use a mask to select
which components are to be debugged. Now, we add the necessary code
to change the mask from sysfs.
