Allow the caller to specify a stack for the child process. If NULL,
...
the child inherits the stack pointer from the parent (traditional
behavior). Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.
This is required for clone(2).

Argh, removed last ELF induced problem. We used to have syscall: in locore.s
...
and _C_LABEL(syscall) in trap.c. In ELF they are the same. Change the label
in locore.s to be _C_LABEL(_syscall).
While I am there, move the register save and restoral code used in the
*sigcode trampolines into two macros and use them instead of copying 100
lines of assembly each time.
Now everything ELF works.

No flags will not work, because it will produce a kernel loaded at 0xf0000000.

* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just

* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot. Also, DO NOT use
pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
access_type = 0. This should probably be revisited.

d0d9bb7669
Dedicate a pair of entry points to handling sun4m level 15 (NMI) interrupts.
...
Hardware NMIs are generated on various fault conditions that take place
asynchronously to the instruction stream. Software NMIs are going to be used
for inter-processor communications.
Get synchronous fault information separately from asynchronous fault
information. Do the former right after taking a memory fault trap and
store the values in temporary locations within the cpuinfo structure (XXX),
so we can unconditionally clear the sync fault status register after
MMU probe operations. This all is to work around a Hypersparc feature
which could lead to loss of fault information because of the fault
status register getting locked.
