7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only 
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

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.

speading port names in arch-dependant code.

start these at 0x10000 to leave room for an increase in the latter.

d9ab16ba2f Purge CLSIZE, CLSIZELOG2 and MCLOFSET. 
Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
  are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

1b1e4bd3d1 Remove hardcoded values for HZ (under different names!) from mcclock.c 
and clock_machdep.h, so that now HZ can be any supported frequency of
the mc146818a/ds1287a RTCs.
Tested at 256Hz and 2048Hz.

e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

add support of multiple memory segments so machines that allow mixed
memory sizes can utilize all available memory.
