#include <i386/isa/isa.h>
	return IO_EISASIZE instead of hard coded 0x1000.

if_ep.c:
	Remove commented out disabling of interrupts that gave a
	"comment withing a comment" warning.

a54907a1a7 Restore my changes to initialize the kdc_shutdown routine pointer. Stefan 
clobbered it in his previous commit and not having it causes the machine
to panic during reboot (as well as not doing the important shutdown callout).

d7a0fc9360 Fixed warning caused by returning a value in a void function (introduced 
in a recent commit by me). Relaxed checks before calling vm_object_remove;
a non-internal object always has a pager.

f5cf85d40a Removed unused fifth argument to vm_object_page_clean(). Fixed bug with 
VTEXT not always getting cleared when it is supposed to. Added check to
make sure that vm_object_remove() isn't called with a NULL pager or for
a pager for an OBJ_INTERNAL object (neither of which will be on the hash
list). Clear OBJ_CANPERSIST if we decide to terminate it because of no
resident pages.

8673e05a9a Completely new PCI code: 
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

c01a9b8ca0 Incorporated 4.4-lite vnode_pager_uncache() and vnode_pager_umount() 
routines (and merged local changes). The changed vnode_pager_uncache

the vnode before calling vnode_pager_uncache.

ab828ab8bd Moved call to vnode_pager_uncache in rename() to before the VOP_RENAME. 
It was previously after the VOP_RENAME and the reference and lock on
the vnode had already been lost, allowing interesting internel
inconsistencies. This is one of the two reasons why freefall was crashing
every hour or two (the other being nullfs bugs).
Don't call vnode_pager_uncache in revoke(). revoke() is only allowed on
VCHR and VBLK vnodes.

4e83f749ec Don't sync the inode date changes of character special devices 
during the FS sync. The system would appear to hang momentarily
if there was a large backlog of I/O. This is because the vnode
remains locked during the output - preventing normal character
I/O. The problem was exacerbated by the FFS contiguous block
allocation fixes and a semi-broken disksort(). The inode/date
will still be synced during a normal FS dismount and whenever
the inode is changed for other reasons.

0c40ff690c Increase the DELAY used in ahc_poll. This is only used during intial 
probe of the device and shouldn't affect normal operation.  It seems that
some version of the aic7870 are extreamly slow in clearing their interrupt
register so the added delay is required to ensure we don't poll a stale
interrupt value.

Clean up debugging printfs and stuff superflous output into #ifdef AHC_DEBUG.

Ensure that sdtrpending and wdtrpending are cleared in all cases after
we recieve an SDTR or WDTR message.

d99c7a23fa This set of patches enables IP multicasting to work under FreeBSD. I am 
submitting them as context diffs for the following files:

sys/netinet/ip_mroute.c
sys/netinet/ip_var.h
sys/netinet/raw_ip.c
usr.sbin/mrouted/igmp.c
usr.sbin/mrouted/prune.c

The routine rip_ip_input in raw_ip.c is suggested by Mark Tinguely
(tinguely@plains.nodak.edu). I have been running mrouted with these patches
for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.

5eb7d0cd2e Special cased the handling of mb_map in the M_WAITOK case. kmem_malloc() 
now returns NULL and sets a global 'mb_map_full' when the map is full.
m_clalloc() has further been taught to expect this and do the right thing.
This should fix the "mb_map full" panics that several people have reported.

okay to wait.

78dfa6036a Removed "-D" option and made symbols load all the time. They will be 
discarded if the kernel isn't built with DDB.
