1) rights should be shared by the threads within a process. While it would
be easier to handle this with the struct proc/struct lwp split, we attempt to
do this now by sharing the right lists. Because each right holds a reference
to struct proc, this might cause some problems later.
2) in pthread_exit, really exit the thread. Also reintialize the righ tlist to
make sure we will not destroy the parent's right list
3) rights can hold multiple permissions on a port (ie: send and receive). Fix th
is.
4) first attempt on right carried by messages. We still have to do rights carrie
d in the message body (complex messages).

- Do call child_return

mach_port_move_member, mach_port_set_attributes, mach_task_set_special_port,

Added mach_thread_create_running, which creates a new Mach thread. It
provides the register context of the new thread. We use it in a child
function provided to fork1(). The child function is machine dependent and
is not yet implemented for i386.
The new thread crashes quickly, but at least it starts.

A working fork/vfork implementation. Darwin fork differs from our fork by
...
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.

fix two bugs in the previous PTE-spill handling changes:
...
- in pmap_pte_spill(), the victim PTE could be using the secondary hash,
in which case its pvo entry is actually in the other bucket. use the
correct bucket for the victim pvo when moving it to the front of its list.
- similarly, in pmap_pvo_remove(), if the pteidx is pre-computed for us,
it might actually point to the other bucket if the entry is using the
secondary hash. adjust ptegidx if this is the case.
these should fix PRs 18645 and 18736.

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.

Split out device register definitions to their own files as the are
...
common across many of the 4xx parts. Leaves ibm405gp.h with device
address information specific to the 405GP CPU. Now allows opb.c to
support multiple 4xx CPU types.

Add a pvr field to 'struct opb_dev', to allow the opb_devs array to

contain info about on-chip devices for more than one CPU type.

Reorganise the IBM 4xx bus layout, using terminology from the IBM
...
documentation:
- Remove "mainbus" altogether.
- The new root is "plb" - the Processor Local Bus.
- Attached to this is the "opb" - the On-chip Peripheral Bus, to which
all the on-chip devices are attached (except the cpu and pci host
bridge).
- Port-specific code can pass an array of 'struct plb_dev' to
config_rootfound() to attach extra devices to the plb. The walnut
port attaches a "pbus" (Peripheral Bus) in here for the RTC and
pc keyboard controller to attach to.
There is still much 405GP specific code; the next round of changes will
generalise this to enable easier support for other 4xx CPUs.

More refinement, only map B_READ buf with VM_PROT_WRITE (all pages always
...
have VM_PROT_READ). Also, pass PMAP_WIRED to pmap_enter (for non-mpc6xx
pmaps). This will give pmap clues about flushing any "icache ok state".

Switch vmap*buf back to using pmap_enter/pmap_remove. This is so that
...
accesses to the buffer will cause the reference and modified bits for
the pages to be udpated appropriately.

MAC (emac). Much thanks to Jason Thorpe for debugging help writing this
