b6c63e2a81 Use <sys/ktr.h> directly in .S files instead of exporting the
KTR_* class macros via genassym.c. Together with sys/sys/ktr.h
rev. 1.34 this has the desired side-effect of providing a default
value for KTR_COMPILE. Thus this fixes warnings from -Wundef
regarding KTR_COMPILE not being defined for .S files.

224d140293 Drop _MACHINE_ARCH and _MACHINE defines (not to be confused with
MACHINE_ARCH and MACHINE).  Their purpose was to be able to test

95d1f36f82 Optimize parallel processing of ipfw(4) rulesets eliminating the locking
of the radix lookup tables. Since several rnh_lookup() can run in
parallel on the same table, we can piggyback on the shared locking
provided by ipfw(4).
  However, the single entry cache in the ip_fw_table can't be used lockless,
so it is removed. This pessimizes two cases: processing of bursts of similar
packets and matching one packet against the same table several times during
one ipfw_chk() lookup. To optimize the processing of similar packet bursts
administrator should use stateful firewall. To optimize the second problem
a solution will be provided soon.

Details:
  o Since we piggyback on the ipfw(4) locking, and the latter is per-chain,
    the tables are moved from the global declaration to the
    struct ip_fw_chain.
  o The struct ip_fw_table is shrunk to one entry and thus vanished.
  o All table manipulating functions are extended to accept the struct
    ip_fw_chain * argument.
  o All table modifing functions use IPFW_WLOCK_ASSERT().

	options BPF_JITTER

	sysctl net.bpf.jitter.enable=0

Currently BIOCSETWF and bpf_mtap2() are unsupported, and bpf_mtap() is
partially supported because 1) no need, 2) avoid expensive m_copydata(9).

7640c87195 The Oxford 16C950 based CardBus Serial device that I was given some
time ago appears to be based not on the typical 1.8432MHz clock, or
the other more typical multiple of 8 of this (14.7456MHz), but instead
it appears to be 1/2 the PCI clock rate or 16.50000MHz.  I'm not 100%
sure that this is right, but since I did the original entry, I'm going
to go ahead and modify it.  With the 14.7456MHz value, I was getting
bits that were ~7.3us instead of ~8.6us like they are supposed to be.

My measuring gear for today is a stupid handheld scope with two
signficant digits.  So I don't know if it is 33.000000/2 MHz or some
other value close to 16.5MHz, but 16.5MHz works well enough for me to
use a couple of different devices at 115200 baud, and is a nice even
multiple of a well known clock frequency...

2dce95a085 Change the i386 code to pass the interrupt vector as a separate argument
rather than embedding it in the intrframe as if_vec.  This reduces diffs
with amd64 somewhat.
- Remove cf_vec from clockframe (it wasn't used anyway) and stop pushing
  dummy vector arguments for ipi_bitmap_handler() and lapic_handle_timer()
  since clockframe == trapframe now.
- Fix ddb to handle stack traces across interrupt entry points that just
  have a trapframe on their stack and not a trapframe + vector.
- Change intr_execute_handlers() to take a trapframe rather than an
  intrframe pointer.
- Change lapic_handle_intr() and atpic_handle_intr() to take a vector and
  trapframe rather than an intrframe.
- GC struct intrframe now that nothing uses it anymore.
- GC CLOCK_TO_TRAPFRAME() and INTR_TO_TRAPFRAME().

ac7326e338 Don't panic if IRQ 13 doesn't exist. On some machines (see previous
commit to atpic.c) there may not be an IRQ 13.  Instead, just keep going.
If the INT16 interface doesn't work then we will eventually panic anyway.

FWIW: We could probably just axe the support for IRQ 13 altogether at this
point.  The only thing we'd lose support for are 486sx systems with
external 487 FPUs.

5ae84c09e7 Really slam the door on mixed mode now that we don't depend on it for a
working IRQ0 with APIC anymore.  Previously, it was possible to have
some other ATPIC IRQS "leak" through in a few edge cases.  For example, on
my x86 test machine, ACPI re-routes the SCI (IRQ 9) to intpin 13 on the
first I/O APIC.  This leaves a hole for IRQ 13 (since the APIC doesn't
provide a source for IRQ 13 in that case) with the result that the ATPIC
IRQ13 source was registered instead.  This changes the 8259A drivers to
only register their interrupt sources if none of the 16 ISA IRQs have an
interrupt source already installed.

5d2162b2f8 Tweak witness handling of lock object to shave 2 pointers off of each
lock object (and thus off of each mutex and sx lock):
- Rename the all_locks list to pending_locks and only put locks initialized
  before SI_SUB_WITNESS on the list so that the SI_SUB_WITNESS can add them
  to witness once it starts up.
- Now that pending_locks is only used during early startup, change it from
  a TAILQ to an STAILQ.  This removes a pointer from the STAILQ_ENTRY in
  struct lock_object.
- Since the pending_locks list is only used during the single-threaded
  early boot it no longer needs to be protected by a mutex, so remove
  all_mtx.
- Since the lo_list member of struct lock_object is now only used during
  early boot before witness is running, collapse lo_list and lo_witness
  into a union.  This shaves the second pointer off of struct lock_object.
- Axe lock_cur_cnt and lock_max_cnt.

With these changes, struct mtx shrinks from 36 to 28 bytes on 32-bit
platforms and from 72 to 56 bytes on 64-bit platforms.  Note that this
commit will completely and utterly destroy the kernel ABI, so no MFC.

8bfc230455 Recent nmount(2) adoption in mount_smbfs(8) did not flag the "long" option
since mount_smbfs(8) assumed long name mounting by default unless "-n long"
was explicitly specified.

Rather than supplying a "long" option in mount_smbfs(8), this commit brings
back the original behaviour by associating SMBFS_MOUNT_NO_LONG with the
"nolong" option.  This should fix the broken long file names on smbfs people
observed recently.

802cab0330 - Rev. 1.175 fixed compilation on sparc64 but also backed out zeroing of
the eaddr array (introduced in rev. 1.174) prior to writing to it. As
  dc_read_eeprom() is told to write only 3 16-bit words to eaddr but eaddr
  in fact is somewhat larger removal of the zeroing defeated the check
  whether the MAC address is all zero as there can be some random garbage
  in eaddr past the 3 words written to it and the check verifys all bits
  in eaddr. Solve this by changing the check to verify only the 3 words
  (happenning to be ETHER_ADDR_LEN bytes) written to eaddr.
- While here change the notation of "FCode" in a nearby comment to the
