| | | | | | | | | | | hold the kernel lock, but still need call one function that needs it. Instead of grabbing the lock all over the place, move the locks into the affected functions: trapsignal, scdebug*, ktrsyscall, ktrsysret, systrace_redirect and ADDUPROF. In the cases we already hold the biglock we'll just recurse. kettenis@, beck@ ok

* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-261-18/+25
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots
* Use suser when possible. Suggested by miod@.fgsch2009-10-311-2/+2
| | | | miod@ deraadt@ ok.
* Remove the VREF() macro and replaces all instances with a call to verf(),thib2009-07-091-2/+2
| | | | | | | | | | | which is exactly what the macro does. Macro's that are nothing more then: #define FUNCTION(arg) function(arg) are almost always pointless and should go away. OK blambert@ Agreed by many.

| | | | | | | | | | | Introduce the cpu_info structure, p_cpu field in struct proc and global scheduling context and various changed code to deal with this. At the moment no architecture uses this stuff yet, but it will allow us slow and controlled migration to the new APIs. All new code is ifdef:ed out. ok deraadt@ niklas@
