a720ae1bbe Sync with zs.
- Fix some bogosity with mixing unit numbers and channels, which would only
  work for one instance of the device.
- Use a simpler scheme for input and output queueing.
- Use db_alt_break.

e548a1d4c8 - Provide backwards compatibility for kern.fallback_elf_brand.
- Use the generic elf type macros in imgact_elf.h instead of ifdefing the
  entire contents of the header.

518a75ea1c Adopt, adapt and improve:
o  Make the URL of the handbook match reality
o  Improve some comments (either wording or formatting)
o  Sync with i386: comment-out DDB, INVARIANTS, INVARIANT_SUPPORT
o  Add some more SCSI/RAID controllers:
	ahd, mpt, asr, ciss, dpt, iir, mly, ida
o  Remove support for the parallel port
o  Add NICs: em, bge
o  Remove NICs: ste, tl, tx, vr, wb
o  Enable USB support again, except of the UHCI host controller.
   UHCI still hangs the BigSur (=HP i2000) machines, and makes
   them useless. The OHCI controller works fine. Note that newer
   ia64 boxes based on the Intel host controllers (UHCI or EHCI)
   still won't have USB support. We really need to import the
   EHCI host controller from NetBSD...

f5b11b6e2d Temporarily introduce a new VOP_SPECSTRATEGY operation while I try
to sort out disk-io from file-io in the vm/buffer/filesystem space.

The intent is to sort VOP_STRATEGY calls into those which operate
on "real" vnodes and those which operate on VCHR vnodes.  For
the latter kind, the call will be changed to VOP_SPECSTRATEGY,
possibly conditionally for those places where dual-use happens.

Add a default VOP_SPECSTRATEGY method which will call the normal
VOP_STRATEGY.  First time it is called it will print debugging
information.  This will only happen if a normal vnode is passed
to VOP_SPECSTRATEGY by mistake.

Add a real VOP_SPECSTRATEGY in specfs, which does what VOP_STRATEGY
does on a VCHR vnode today.

Add a new VOP_STRATEGY method in specfs to catch instances where
the conversion to VOP_SPECSTRATEGY has not yet happened.  Handle
the request just like we always did, but first time called print
debugging information.

Apart up to two instances of console messages per boot, this amounts
to a glorified no-op commit.

If you get any of the messages on your console I would very much
like a copy of them mailed to phk@freebsd.org

a360a43dd5 Improve the way that an elf image activator for an alternate word size is
included in the kernel.  Include imgact_elf.c in conf/files,  instead of
both imgact_elf32.c and imgact_elf64.c, which will use the default word
size for an architecture as defined in machine/elf.h.  Architectures that
wish to build an additional image activator for an alternate word size can
include either imgact_elf32.c or imgact_elf64.c in files.${ARCH}, which
allows it to be dependent on MD options instead of solely on architecture.

3c3871e5e6 Introduce the
void backtrace(void);
function which will print a backtrace if DDB is in the kernel and an
explanation if not.

This is useful for recording backtraces in non-fatal circumstances and
does not require pollution with DDB #includes in the files where it
is used.

It would of course be nice to have a non-DDB dependent version too,
but since the meat of a backtrace is MD it is probably not worth it.

4bf2855c97 Use a separate macro to generate the name of the sysctl_oid_list that holds
the children of a sysctl node, so that the arguments to the SYSCTL_NODE
macro can themselves be macros.  It would be nice to use __CONCAT throughout
this file, but the macros are so large that it quickly becomes unweildly,
(4 nested __CONCATs).

c6e3ae999b Since Jeffr made the std* functions the default in rev 1.63 of
kern/vfs_defaults.c it is wrong for the individual filesystems to use
the std* functions as that prevents override of the default.

7b6172abb3 Use __CONCAT and __XSTRING when concatenating or stringifying arguments to

5dadd17b08 Add a sysctl to get the vm protections for the stack of the current process.
On architectures with a non-executable stack, eg sparc64, this is used by
libgcc to determine at runtime if its necessary to enable execute permissions
on a region of the stack which will be used to execute code, allowing the
call to mprotect to be avoided if the kernel is configured to map the stack
executable.
