sys/ia64/ia64 procfs_machdep.c
Log:
Lock the procfs functions for doing a single step and reading/writing
registers better. Hold sched_lock not only for checking the flag but
also while performing the actual operation to ensure the process doesn't
get swapped out by another CPU while we the operation is being performed.
