af59b63bbd We now have the exact stack initial stack layout of Darwin: 
macho_hdr, argc, *argv, NULL, *envp, NULL, progname, NULL,
*progname, **argv, **envp

Where progname is a pointer to the program name as given in the first
argument to execve(), and macho_hdr a pointer to the Mach-O header at
the beginning of the executable file.

1af0fa979f Better immitate Darwin startup stack layout: there is a slot for the program 
name after envp, and the 0x1000 at the beginning is a pointer to the binary

fe8f53c2a4 in mach_sys_map_fd, if the mapping failed because of the requested place 
is already used, we want to remap to another place. The vmcmd must be

been modified by the first mapping attempt.

873ed6f9ee Added support for Darwin's PowerPC-only system calls: 
ppccalls, with system call numbers starting at 0x6000
fasttraps, with system call numbers starting at 0x7FF0

Because the Mach system call dispatching code has grown a bit
too much, introduce an inline function to handle it (mach_syscall_dispatch).

While we are there, remove the Mach and Linux includes from
arch/powerpc/powerpc/syscall.c and push them into
arch/powerpc/powerpc/{mach|linux}_syscall.c

scw
cb52115837 In preparation for COMPAT_NETBSD32 on SH-5: 
- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
   instead of using u_int32_t everywhere,
 - The MD netbsd32_machdep.h header now defines a macro (at least on
   current implementations) which converts a 32-bit pointer to its 64-bit
   equivalent,
 - Change the MI code to utilise the above two items in all the right places,
 - Implement netbsd32___sigaction_sigtramp().

Tested on Sparc64 by Matt Green.

e0cc03a09b merge kqueue branch into -current 
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

eeb799a6c9 Implement MAP_LOCAL option to mmap, which enable the mapping of regions 
private to the process within the share group.

There is one bit missing in this implementation: when replicating a change
in a process VM to the other process of the share group, we avoid copying
mappings for private regions in the target process, but we don't prevent
copying private regions from the source process.

deca50b66c Fill BADVADDR and CAUSE in sigcontext. We still don't restore them, but 
it actually fixes a problem:
When /bin/sh gets a SIGSEGV, its signal handler calls brk and the offending
instruction is retried. Usually it gets another SIGSEGV, and things loops
until it pases without the SIGSEGV. This is the normal mode of operation, and
it can be reproduced on IRIX by a 10kB shell script starting by echo /*

However... the signal handler checks for BADVADDR in the saved registers
in struct sigcontext. If it does not find it, it gives up and exit instead
of retrying. Filling the field enables us to carry on normal operation
(which is to get dozens of SIGSEGV) instead of getting a failure at the
first SIGSEGV.
