native version does non executable mappings on the stack. This is a
showstopper for Linux binaries.

binaries, with the executable bit set.

13f8d2ce5f Dynamic sysctl. 
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

939df36e55 add support for non-executable mappings (where the hardware allows this) 
and make the stack and heap non-executable by default.  the changes
fall into two basic catagories:

 - pmap and trap-handler changes.  these are all MD:
   = alpha: we already track per-page execute permission with the (software)
	PG_EXEC bit, so just have the trap handler pay attention to it.
   = i386: use a new GDT segment for %cs for processes that have no
	executable mappings above a certain threshold (currently the
	bottom of the stack).  track per-page execute permission with
	the last unused PTE bit.
   = powerpc/ibm4xx: just use the hardware exec bit.
   = powerpc/oea: we already track per-page exec bits, but the hardware only
	implements non-exec mappings at the segment level.  so track the
	number of executable mappings in each segment and turn on the no-exec
	segment bit iff the count is 0.  adjust the trap handler to deal.
   = sparc (sun4m): fix our use of the hardware protection bits.
	fix the trap handler to recognize text faults.
   = sparc64: split the existing unified TSB into data and instruction TSBs,
	and only load TTEs into the appropriate TSB(s) for the permissions.
	fix the trap handler to check for execute permission.
   = not yet implemented: amd64, hppa, sh5

 - changes in all the emulations that put a signal trampoline on the stack.
   instead, we now put the trampoline into a uvm_aobj and map that into
   the process separately.

originally from openbsd, adapted for netbsd by me.

jdolecek
94b152275c add Linux compat arg wrapper for ftruncate64(), and change linux compat 
truncate64() wrapper to translate args structure
NetBSD truncate() and ftrucate() have hidden 'pad' argument, so we have
to do the argument translation

Problem found and patch supplied in PR kern/22360 by Ales Krenek

This is the last of syscalls with hidden 'pad' arg we didn't have
wrapper for; all the others (lseek, mmap, pwrite, pread) already had
wrapper before.

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.

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.

implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
  that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.

tested only on i386.

Status:
	gdb, telnet, work
	jdk-1.4.0 extractor works, jdk still coredumps.
