- cpuclass should be cpu_class
- CPUCLASS_I386 should be CPUCLASS_386
(^^ those only show up if you compile for i386)
- two missing prototypes on new functions
- one missing static
Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish
overhead for merged cache.
Efficiency improvement for vfs_cluster. It used to do alot of redundant
calls to cluster_rbuild.
Correct the ordering for vrele of .text and release of credentials.
Use the selective tlb update for 486/586/P6.
Numerous fixes to the size of objects allocated for files. Additionally,
fixes in the various pagers.
Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources. The pageout code
will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
that happens every 30seconds.
Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
case of filesystems mounted async.
Fix a panic with busy pages when write clustering is done for non-VMIO
buffers.
Save 112K for SB, 64K for PAS and 64K for MSS.
Since PAS use SB emulation, 176K normally saved for it.
Few minor optimizations added like in Linux driver.
When you start tracker and produce some heavy disk activity,
output interrupts becomes lost and I don't know how to solve it
finally. Newly added code at least allows recovery after timeout.
2) Use CURSIG(curproc) in PROCESS_ABORTING instead of junk code was there.
3) Reanimate timeout code in DO_SLEEP by setting WK_TIMEOUT flag
which is never set in old code.
4) DO_SLEEP: set aborting flag on interrupting singnals as supposed, not
on signals which do nothing as in old code.
5) Cleanup WAKE_UP macro, WK_WAKEUP not used.
6) Remove wrong typecasts in sleep/wakeup code.
This random address can be matched (with some probability) with another
sleep addresses from other drivers, which can cause strange sleep/wakeup
sequence. Rewrite this ugly code to do the right thing.
Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format
- left padding
* read width as next arg.
n numeric in (argument specified) default radix.
Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.
The warnings from gcc may become more wrong and intolerable because
of this.
Warning: I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

it out fixes my problem but hoses the GUS MAX probe messages. Check what
device we have and print things appropriately for each.

variants, idea taken from NetBSD clock.c.
At least year calculation was wrong, pointed by Bruce.
Use different strategy to store year for BIOS without RTC_CENTURY
are about to go in. This is to fix the problem with the ibcs2 and linux
lkm's not being able to call the sysv ipc functions unless the build is
modified.
in the future, these drivers won't need to maintain an array of
configured units. They still need to because ISA interrupt handlers
take a unit number. :(
Pass "softc" pointers instead of unit numbers to many functions that
did a conversion of unit->softc anyway.
this driver no longer needs to maintain an array of configured units.
