require that all bus tags have pointers to bus_space_read/write functions,
i.e. no run-time hunting for the first "upstream" implementation.
Since this changes the way bus tags should be constructed it makes sense
to do the same thing for the rest of the bus space methods.
So, now bus space tags are generally constructed by copying the parent's bus
tag and then overriding the methods that the bus driver needs to handle,
instead of starting with an empty bus tag and fiiling in only the fields needed.
This allows boot1() to change the sector number (of the boot partition)
that bootxx.S passes through to boot2().
This means that boot2() will find the correct partition when boot1()
reads /boot from the 'a' partition instead of the mbr boot partition.
This all happens when you update a system that used a small 'wd0h' partition
to boot a raid1 set to the new bootcode. Deleting /boot from the 'wd0h'
partition will make the new bootcode find /boot and the root filesystem
inside the raid set.
- "intrusive" dirops now have more chances to get benefits from dnlc.
- fixes a deadlock due to vnode locking order inversion.
nfs_create and others: purge stale dnlc entries
as nfs_lookup() no longer does it automatically.
want more flexible namecache handling.
it just looks up a dnlc entry and vget() the result vnode.
ie. no automatic entry removal, no automatic vnode locking.
discussed on tech-kern@.
1) Introduce functions to allocate and free the emergency IO buffers.
2) Make sure we free any allocated emergency buffers in the event that
we bail out during configuration, or when we unconfigure an array.
3) if we run out of memory trying to allocate a given type of buffer,
don't continue to try to allocate more of those buffers.

1. Pass the caller-supplied protocol name down through ipsec_switch().
2. Remove my poor attempt to print fast-ipsec stats automagically for
`netstat -s'. The previous code would print (fast)IPsec per-protocol
stats even for 'netstat', which is just wrong.
A better fix would be to enumerate the sub-"protocols" under IPsec;
but first lets fix the broken behaviour now, for a pullup to 2.0.
we're executing on; besides dealing with the bits not implemented in the
601's MSR it also removes the silent failure behaviour when passing
PSL_VEC set on a CPU not implementing it.
Also, fix those masks for the 4xx again.
doesn't advance while we're waiting on the lock. In fact, try to take
the lock even before blocking interrupts: the lock is locking "lasttime"
against other callers of cc_microtime(), not against the clock routines,
and if we take a clock interrupt while waiting for the lock, that's one
we don't have to take after the computations, but before returning to
the caller, and that makes the data a little fresher to the caller.
Moreover, inverting the order of splXXX() and simple_lock() permits us
to unblock interrupts before doing the long division.
With this, finally, performance of "ntpd" on my MP i386 seems to be no
worse than on non-MP i386, so this may fix PR kern/24207.
that the Macbinary files in the "misc" directly are now directly executable
from within Mac OS. This solves a "chicken-and-egg" problem: you can't even
distribute a tool to unpack the archives on a plain ISO image, as the
executable code is all in the resource fork on mac68k. In other words, a
user can now begin the installation by simply double-clicking on the Booter
program on the CD-ROM.
