139cdc3125 Make nbuf, nswbuf, and bufpages unsigned. Make all operations on these 
variables unsigned, and update places where their values are printed.

0b956d0b8b Implement pmc(9) -- An interface to hardware performance monitoring 
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.

3912e469dd Rename cdev_systrace_init() to cdev_clonemisc_init(), so it can 
be properly used by any misc. cloning device.  While here, correct
a comment to indicate that "open" is the only entry point and that
everything else is handled with fileops.

bef00d4895 m68k syscall rototill: 
- Switch all m68k-based ports over to __HAVE_SYSCALL_INTERN.
 - Add systrace glue.
 - Define struct mdproc in <m68k/proc.h> instead of <machine/proc.h>.
   (They were all defined exactly the same anyway, other than a couple
   of the MDP_* flags.)

f12f20db6c Apply patches from Christian Limpach: 
- NeXT label reading support
    - SCSI dma fixes
    - media support for if_xe.c

Some of these need more cleanup, but at least make SCSI support usable on
the NeXT.

fde6ae6f04 Enable "pseudo-device clockctl" in all kernels, except 
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

60b6f587bc Subtract vm_map_min(kernel_map) from kernel virtual addresses to get offsets 
into kernel_object where this was missing.
This is a no-op on ports where VM_MIN_KERNEL_ADDRESS==0, ie all but
cesfic.
Confirmed and corrected by Chuck Silvers.

89924fe79b Fix race condition between the DMA handler (which gets called 
on spldma), and rest of driver/network code (which runs on splnet) in way
if->if_snd queue is accessed. Solve by using intermediate queue.

d50107af75 Comment out QUOTA as well. Suggested by Christian Limpach 
in port-next68k/16792.
Applied even tho not strictly necessary, kernel nowadays actually
links with this option too.

g/c the -Wno-main and HAVE_GCC28 stuff

31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for 
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

39b858e3bf Add new RF_* options for RAIDframe bits that are no longer built by default. 
While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.

Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.
