bedeb98a21 Add support for splitting the register windows on entry to the
kernel from usermode.  The remaining user windows are spilled
to the pcb as necessary.  The user land window fault handlers
fill directly from the pcb on return.

22613ae234 Avoid sleeping while holding a mutex in dounmount(). This problem
has existed for a long time, but I made it worse a few months ago
by by adding calls to VFS_ROOT() and checkdirs() in revision 1.179.

Also, remove the LK_REENABLE flag in the lockmgr() call; this flag
has been ignored by the lockmgr code for 4 years. This was the only
remaining mention of it apart from its definition.

38b8e2e37e Clean up some ways in which we set defaults for SCSI cards
that do not have valid NVRAM. In particular, we were leaving
a retry count set (to retry selection timeouts) when thats
not really what we want. Do some constant string additions
so that LOGDEBUG0 info is useful across all cards.

05c33a209b Limit the amount of KVM reserved for the buffer cache and for swap-meta
information.  The default limits only effect machines with > 1GB of ram
and can be overriden with two new kernel conf variables VM_SWZONE_SIZE_MAX
and VM_BCACHE_SIZE_MAX, or with loader variables kern.maxswzone and
kern.maxbcache.  This has the effect of leaving more KVM available for
sizing NMBCLUSTERS and 'maxusers' and should avoid tripups where a sysad
adds memory to a machine and then sees the kernel panic on boot due to
running out of KVM.

Also change the default swap-meta auto-sizing calculation to allocate half
of what it was previously allocating.  The prior defaults were way too high.
Note that we cannot afford to run out of swap-meta structures so we still
stay somewhat conservative here.

33c3c53a53 Improve interlocking for card removal. We now can remove the card in
the ISR.  We keep track of the card state and don't call the IRS when
the card isn't inserted.  This helps quite a bit with card ejection
problems that Ian was seeing.

5e416567e1 Implement a LOCAL_PEERCRED socket option which returns a
`struct xucred` with the credentials of the connected peer.
Obviously this only works (and makes sense) on SOCK_STREAM
sockets.  This works for both the connect(2) and listen(2)
callers.

There is precise documentation of the semantics in unix(4).

6e94a734c7 Restore initialization of ahc->unpause lost in rev 1.76. ahc->unpause
should be initialized to 0 for PCI adapters which was a side-effect of
the memset in ahc_alloc().  EISA/VL adapters require our unpause value to
include the "levelness" of our interrupt.

This change allows EISA adapters to work again.
