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.

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().

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.

80ee637534 - Introduce a e_fault field in struct proc to provide emulation specific
memory fault handler. IRIX uses irix_vm_fault, and all other emulation
use NULL, which means to use uvm_fault.

- While we are there, explicitely set to NULL the uninitialized fields in
struct emul: e_fault and e_sysctl on most ports

- e_fault is used by the trap handler, for now only on mips. In order to avoid
intrusive modifications in UVM, the function pointed by e_fault does not
has exactly the same protoype as uvm_fault:
int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t));
int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t));

- In IRIX share groups, all the VM space is shared, except one page.
This bounds us to have different VM spaces and synchronize modifications
to the VM space accross share group members. We need an IRIX specific hook
to the page fault handler in order to propagate VM space modifications
caused by page faults.

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.

830c5c171a Implement passing AT_{E,R}{U,G}ID in the elf aux vector, like solaris.
- pass struct proc to copyargs.
- eliminate svr4_copyargs, since it is the same as ours now.

652fe89179 - add locks to structures used by the /dev/usema driver and the
usync_cntl() system calls.

- when usync_cntl is used and the process is aborted (eg: by kill -9)
libc does not call usync_cntl() to unblock things. We have to cleanup
data allocated in the kernel. This is now done through the emulation
specific exit hook

- IRIX initialize some data in the system part of the PRDA: the pid and
a prid (PRDA ID?). We initialize both to pid.

- Move back struct irix_share_group from irix_exec.h to irix_prctl.h, it
is more revelant here.

- fix a few typos

02eb342b57 Make sure that the pointer to old parent process for ptraced children
gets reset properly when the old parent exits before the child. A flag
is set in old parent process when the child is reparented in ptrace(2).
If it's set when process is exiting, all running processes have their
'old parent process' pointer checked and reset if appropriate. Also
change to use 'struct proc *' pointer directly, rather than pid_t.
This fixes security/14444 by David Sainty.

011d4d5f44 Add kernel support for having userland provide the signal trampoline:
* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.
