bd2ddd5fd4 after enqueue()ing a process, only pick_proc() a new one if the current 
process is not PREEMPTIBLE (or it's not ready, or there isn't a current
process yet). This fixes a case where a process that isn't
PREEMPTIBLE actually gets preempted. (This solves a race condition
between CLOCK and SYSTEM.)

6d50591226 . let kernel use read_tsc() from sysutil library 
. read_tsc() in sysutil library saves edx and eax now
 . added read_tsc_64() by Antonio Mancina to load tsc into
   a 64-bit data type directly
 . deleted read_tsc.h in favour of a prototype in <minix/syslib.h>

238ae978ba Don't allow sys_kill to SELF alltogether. 2007-02-23 13:01:55 +00:00
Ben Gras
a9f2f36f46 If a process does sys_kill on SELF (such as in panic() of servers and drivers 
if a PM exit fails, until they are compiled with the new panic() function that
is), don't reply to it as the endpoint has been cleared.
