25dec7474c If a socket is disconnected for some reason (like a TCP connection
not responding) then drop any data on the outgoing queue in
soisdisconnected because there is no way to get it to its destination
any longer.

The only objection to this patch I got on -net was from Terry, who
wasn't sure that the condition in question could arise, so I provided
some example code.

30bbe52432 Implement a direct mapped address region, like alpha and ia64. This
basically maps all of physical memory 1:1 to a range of virtual addresses
outside of normal kva.  The advantage of doing this instead of accessing
phsyical addresses directly is that memory accesses will go through the
data cache, and will participate in the normal cache coherency algorithm
for invalidating lines in our own and in other cpus' data caches.  So
we don't have to flush the cache manually or send IPIs to do so on other
cpus.  Also, since the mappings never change, we don't have to flush them
from the tlb manually.
This makes pmap_copy_page and pmap_zero_page MP safe, allowing the idle
zero proc to run outside of giant.

586261a30f Reserve VCACHEDLABEL vnode flag for use by the TrustedBSD MAC
implementation.  This flag will indicate that the security label
in the vnode is currently valid, and therefore doesn't need to
be refreshed before an access control decision can be made.  Most
file systems (or stdvops) will set this flag after they load the
MAC label from disk the first time to prevent redundant disk I/O;
some file synthetic file systems (procfs, for example) may not.

d06c0d4d40 Slight restructuring of the logic for credential change case identification
during execve() to use a 'credential_changing' variable.  This makes it
easier to have outstanding patchsets against this code, as well as to
add conditionally defined clauses.

ce39e722ec Disable optimization of spinlocks on UP kernels w/o debugging for now
since it breaks mtx_owned() on spin mutexes when used outside of
mtx_assert().  Unfortunately we currently use it in the i386 MD code
and in the sio(4) driver.

	o Init MFUNC if it is zero and the TI part has a MFUNC register
	  at offset 0x8c (1030, 1130 and 1131 don't have anything there, the
	  1250,1251,1251B and 1450 have a different thing there.  The rest
	  have it.  TI is likely to only do MFUNC from now on.  The IRQMUX
	  in the 1250 series of chips needs no tweaks.
	o Adjust to new exca interface.
	o Add comments about TI chips that I learned in talking to an
	  engineer at TI.
	o Add register definitions for MFUNC.

e277218592 Frequency default should be '25' for 25MHz, not 25000000.
Through the PITA of endiannness, clock has to be MHz freq << 8.

72429e49f5 Make sure that if are in fact using 'full SMP', make the interrupt
flags include INTR_MPSAFE. Put the flags in a common place so that
both isp_sbus && isp_pci DTRT.

In isp_mbxdma setup, drop any locks prior to calling things like
bus_dmatag_create. This gets rid of these obnoxious WITNESS messages
about 'sleeping with locks held' blah blah blah blah blah.
