Modified files:
sys/miscfs/procfs procfs.h procfs_mem.c procfs_regs.c
procfs_vnops.c
Log:
Fix procfs security hole -- check permissions on meaningful I/Os (namely,
reading/writing of mem and regs). Also have to check for the requesting
process being group KMEM -- this is a bit of a hack, but ps et al need it.
