*sigh*.  Can someone else test/commit this?

I've not been able to boot a 2.5.51 kernel on either A500-44 or C3000.
I won't commit what I can't test when others are obviously booting
2.5.51 kernels. My last attempts on A500-44 data page fault on
a NULL dereference in "$lctu_loop+8" (GR02 is sys_nanosleep+13c).
Panic seems to be after (AFAICT) all the RC scripts have run.
I'm at the end of my rope on 2.5.51.

I've placed the diff on ftp.parisc-linux.org:/patches/diff-2.5.51-pa5
The patch *looks* right and fixes a few other nits.
Should work on both PA1.1 and PA2.0 machines.
(and we have to use STREGM/LDREGM to support both variants).

thanks again and apologies for not committing it as promised.
