Increase the overall length of the delay by 10.
Without this a 3C509 card on my MediaGX crash box can't be reliably
read. With this it is solid.
I've left a delay multiplier in instead of just changing the base
delay because I'm surprised I had to increase it so much and expect
there may be another problem.
Change microseq offsets. Previously, offsets of the program counter where
added to the index of the current microinstruction. Make them rely on the
index of the next executed microinstruction.

Sun implemented iBCS2 compatibility on Solaris >= 2.6: The emulator
runs in user-mode, patching the LDT so that client programs making
syscalls through the old iBCS2 call gate get handled by the emulator
process. Unemulated syscalls therefore need their own call-gate that
bypasses the emulator. Sun chose LDT entry 4 to implement this, which
is what we've been using as LUDATA_SEL, so we need to change LUDATA_SEL
if we want to run Solaris executables.

also a bit of a BDE patch in there I beleive. Backs out a fix I needed for Cyrix support
early on but it turns out that a later fix in the cyrix support made it un-needed.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.
As the author says:
|I ran into a problem pulling out the VM_STACK option. I was aware of this
|when I first did the work, but then forgot about it. The VM_STACK stuff
|has some code changes in the i386 branch. There need to be corresponding
|changes in the alpha branch before it can come out completely.
what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in. This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches. The vm_map_entry will then always have one
|extra element (avail_ssize). It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c. This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch. I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

This takes the conditionals out of the code that has been tested by
various people for a while.
ps and friends (libkvm) will need a recompile as some proc structure
changes are made.

changes to the VM system to support the new swapper, VM bug

forced commits. This commit is somewhat rough in regards to code

lock, and add some macros and function parameters to make sure that
the information get to the point where it can be put in the lock

While I'm here, add DEBUG_VFS_LOCKS to LINT.
pnp system in freebsd, I'm not sure how useful this will be, but my
1542CP seems to work well in plug and play mode and does seem to
probe correctly at all the oddball addresses/irq/drqs that I tried.
[[
I was unable to get /kernel.conf or /kernel.config to read in, so
I wasn't able to verify that this method of userconfig works. that's
one thing that makes pnp so hard to use in the current scheme.
Pointers to the right new way of doing this accepted.

o Add some kludges to maybe bring support for 1540A/1542A into the
driver. Since I have no 154xA cards, and the only person I know
that has them hasn't given me feedback, I'm making this commit
blind.
o Honor unit numbers that are in the config file now. This allows one
to hard wire the unit numbers (and have high unit numbers for plug
and pray devices, which can't seem to be hardwired) and have the
cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.
