Modified Files:
        src/sys/sys: atomic.h

Log Message:
sys/atomic.h: Fix hashlocked atomic stores, e.g. on sparc and hppa.

Casting (uint32_t *)p does not actually round p down to a mulitple of
sizeof(uint32_t)!  Oops.

Likely fix for:

PR port-sparc/59321: t_npf tests are failing

and probably various other sparc and hppa issues.  (I have not been
able to reproduce this failure, but the evidence from the assertion
output is that the atomic_load_* calls are coming from inside the
atomic.h house -- and there are only two of those outside macro
expansions, and they're both in __do_atomic_store.)

Now it would be nice if the stack trace went a little further than
the kern_assert call so I didn't have to puzzle over that one to
figure out where it was coming from...
