964f16c2b9 Make fork use kauth. 
Been running in my tree for over a month at least.

Reviewed and okay yamt@, and special thanks to him as well as rittera@
for making this possible through fixing NDIS to not call fork1() with
l1 != curlwp.

0b5d0f6802 Actually copy the ras list onto the child process during fork() - hi ad. 
Might fix the 'ras' part of kern/37650.
For some reason the itimers aren't inherited either.

77e0b2120f Patch up sysctl locking: 
- Lock processes, credentials, filehead etc correctly.
- Acquire a read hold on sysctl_treelock if only doing a query.
- Don't wire down the output buffer. It doesn't work correctly and the code
  regularly does long term sleeps with it held - it's not worth it.
- Don't hold locks other than sysctl_lock while doing copyout().
- Drop sysctl_lock while doing copyout / allocating memory in a few places.
- Don't take kernel_lock for sysctl.
- Fix a number of bugs spotted along the way

cfde7482cd Actually return the computed uptime in microuptime(). Fixes many 
wierd timing issues on non-timecounter ports (tested on sbmips, and
omap ARM by Marty Fouts).

Also move the microtime() inside the splclock() block in the same
function - it may be possible for the "time" variable to be updated
after the call to microtime() but before we use it to calculate the
offset from mono_time.

1dd75d2865 Add a simple in-kernel linker, derived from FreeBSD's link_elf_obj.c. Needs 
more work but is enough to load simple LKMs. amd64 is untested.

Locking is caller provided. This is decoupled from the LKM framework because
kernel modules need not be loaded from the file system - they could be built
into the kernel and referenced via link set.

a72fb242fe Add tc_detach() for detaching a timecounter. It is good enough to 
detach the AMD Geode SC1100 27 MHz clock, geodecntr(4), but there
may be synchronization problems on MP machines.

c68e4b1c69 remove PIPE_WANTW, PIPE_WANTR and PIPE_WANTCLOSE. cv_waiters is enough. 
this fixes a deadlock between pipe_direct_write and pipeclose.

XXX this code should be simplified.
it's mostly pointless to have two struct pipes linked together,
esp. when we don't support bi-directional pipes.
