c4778b5d1c MFp4: Change struct fw_xfer to reduce memory copy in fwmem_*() functions.
And many changes.

* all
	- Major change of struct fw_xfer.
		o {send,recv}.buf is splitted into hdr and payload.
		o Remove unnecessary fields.
		o spd is moved under send and recv.
	- Remove unnecessary 'volatile' keyword.
	- Add definition of rtcode and extcode.

* firewire.c
	- Ignore FWDEVINVAL devices in fw_noderesolve_nodeid().
	- Check the existance of the bind before call STAILQ_REMOVE().
	- Fix bug in the fw_bindadd().
	- Change element of struct fw_bind for simplicity.
	- Check rtcode of response packet.
	- Reduce split transaction timeout to 200 msec.
		(100msec is the default value in the spec.)
	- Set watchdog timer cycle to 10 Hz.
	- Set xfer->tv just before calling fw_get_tlabel().

* fwohci.c
	- Simplifies fwohci_get_plen().

* sbp.c
	- Fix byte order of multibyte scsi_status informations.
	- Split sbp.c and sbp.h.

c142b0fcfe Remove the global variable 'cmask', which was used to initialize the
fd_cmask field in the file descriptor structure for the first process
indirectly from CMASK, and when an fd structure is initialized before
being filled in, and instead just use CMASK.  This appears to be an
artifact left over from the initial integration of quotas into BSD.

6ccf265bb0 Commit Bosko's patch to clean up the PSE/PG_G initialization to and
avoid problems with some Pentium 4 cpus and some older PPro/Pentium2
cpus.  There are several problems, some documented in Intel errata.
This patch:
1) moves the kernel to the second page in the PSE case.  There is an
errata that says that you Must Not point a 4MB page at physical
address zero on older cpus.  We avoided bugs here due to sheer luck.
2) sets up PSE page tables right from the start in locore, rather than
trying to switch from 4K to 4M (or 2M) pages part way through the boot
sequence at the same time that we're messing with PG_G.

For some reason, the pmap work over the last 18 months seems to tickle
the problems, and the PAE infrastructure changes disturb the cpu
bugs even more.

A couple of people have reported a problem with APM bios calls during
boot.  I'll work with people to get this resolved.

19288f738a Enable net.isr.enable by default, causing "delivery to completion"
(direct dispatch) in interrupt threads when the netisr in question
isn't already active.  If a netisr is already active, or direct
dispatch is already in progress, we queue the packet for later
delivery.  Previously, this option was disabled by default.  I have
measured 20%+ performance improvements in IP packet forwarding with
this enabled.

Please report any problems ASAP, especially relating to stack depth or
out-of-order packet processing.

4e513b7a01 Allow the compiler to micro-optimize byte swapping functions by
evaluating them at compile time rather than at run time.  As for x86
and amd64, this requires GCC and it's enabled only if __OPTIMIZE__ is
defined (ie, if at least -O is used).

6e478cc056 Introduce new __predict_false(exp) and __predict_true(exp) keywords.
Their purpose is to give explicit hints to the compiler to judge
the likelyhood of a test to succeed or fail.  Not all architectures
have support for such optimizations, but for those who do, it can
give a nice performance improvement in hot loops.

Obviously, this should be used very rarely in very specific code.

fa3f9daae5 - On my Pentium4-M laptop, invalpg takes ~1100 cycles if the page is found in
the TLB and ~1600 if it is not.  Therefore, it is more effecient to
   invalidate the TLB after operations that use CMAP rather than before.
 - So that the tlb is invalidated prior to switching off of a processor, we
   must change the switchin functions to switchout functions.
 - Remove td_switchout from the thread and move it to the x86 pcb.
 - Move the code that calls switchout into swtch.s.  These changes make this
   optimization truely x86 specific.
