atomic_set_mask() and atomic_clear_mask() are the pairs, so the related
parameters' type need match with each other.
The type of 'addr->counter' is 'int', so use 'unsigned int' instead
of 'unsigned long', and let atomic_set_mask() match atomic_clear_mask().
For arch sub-system, currently, have 3 types of definition for them:
1st for 'int', 2nd for 'long', 3rd is conflict to use 'int' and 'long'.
At least, better to fix 3rd (conflict using 'int' and 'long').
using 'long':

Shouldn't this become "unsigned int tmp" for consistency, too?

Likewise.
There may be other places that need changes.

It seems better. (although I guess: for 'm32r', both 'long' and 'int'
are 32-bit).
I will wait for 1 day at least, if no additional suggestions or
completions, I will send patch v2.

In your subject line, "geniric" is spelled incorrectly. The correct
spelling is "generic."

Hello Maintainers:
Firstly thank the s390 maintainers again for their 'Acked-by' (in my
memory, s390 is the most important business mainframe machine)
Could another related maintainers give a glance for it, when you have time.
Thanks.
