For example, if bit 31 is set in the cpuid feature word, then %b would print out the initial value as a 16 character hexadecimal value. Now it only prints out an 8 character value.

| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | New locks are: - pgrpsess_lock which locks the whole pgrps and sessions, - pg_mtx which protects the pgrp members, and - s_mtx which protects the session members. Please refer to sys/proc.h for the coverage of these locks. Changes on the pgrp/session interface: - pgfind() needs the pgrpsess_lock held. - The caller of enterpgrp() is responsible to allocate a new pgrp and session. - Call enterthispgrp() in order to enter an existing pgrp. - pgsignal() requires a pgrp lock held.

* Fixes for a couple of problems in last commit:Peter Wemm1999-07-101-8/+8
| | | | | | | | | | | | | | | | | | | | 1. Printing large quads in small bases overflowed the buffer if sizeof(u_quad_t) > sizeof(u_long). 2. The sharpflag checks had operator precedence bugs due to excessive parentheses in all the wrong places. 3. The explicit 0L was bogus in the quad_t comparison and useless in the long comparision. 4. There was some more bitrot in the comment about ksprintn(). Our ksprintn() handles bases up to 36 as well as down to 2. Bruce has other complaints about using %q in kernel and would rather we went towards using the C9X style %ll and/or %j. (I agree for that matter, as long as gcc/egcs know how to deal with that.)
