2268ca475b correct pkthdr length calculation for ipv6 echo packets; after moving a packet
header with M_MOVE_PKTHDR one should not reference the packet header in the
original packet; in this case the code was assuming that m_adj would alter
m_pkthdr.len which stopped happening because M_MOVE_PKTHDR removes the
M_PKTHDR bit from m_flags

c58d580e70 Don't hardcode the address of the local (S)APIC (aka processor
interrupt block). We use the previously hardcoded address as a
default only, but will otherwise use whatever ACPI tells us.
The address can be found in the MADT table header or in the
LAPIC override table entry.

ff263ea2dc Bump the number of interrupts from 65 to 257. This is a waste of
space most of the time, but handles machines with lots of I/O
(S)APICs. We cannot make this more dynamic without breaking the
interface with vmstat. Hence, we need to fix the interface first.

671f297efb Handle 3-digit interrupt numbers (vectors). While here, change the
name of unused entries from "intr XXX" to "#XXX". This makes it
easier to debug interrupt problems, because vmstat can be hacked
more easily to dump all interrupt entries that are in use and not
those that have had interrupts.

d291811a6a Make all memory I/O addresses (explicitly) 64-bit. Memory mapped
devices aren't necessarily mapped within 4GB. I/O port addresses
are offsets into the memory mapped I/O port space, which is not
larger than 16MB. No need to convert those to 64 bit types.

7a976ae838 Don't override the vop_lock, vop_unlock and vop_isunlocked methods.
Previously all filesystems which relied on specfs to do devices
would have private overrides for vop_std*, so the vop_no* overrides
here had no effect.  I overlooked the transitive nature of the vop
vectors when I removed the vop_std* in those filesystems.

Removing the override here restores device node locking to it's
previous modus operandi.

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.
