Revert to using ointhand2_t rather than inthand2_t. Use unwise casts
to pass pointers as ints in i386 only code. This will be fixed in the
future as the transition to newbus completes.
This eliminates the warnings and still works.
Add $FreeBSD$ to driver.h and pcic.c
fixed (many due to changing semantics in other parts of the kernel and not
the original author's fault), including one critical one: unionfs could
cause UFS corruption in the fronting store due to calling VOP_OPEN for
writing without turning on vmio for the UFS vnode.
Most of the bugs were related to semantics changes in VOP calls, lock
ordering problems (causing deadlocks), improper handling of a read-only
backing store (such as an NFS mount), improper referencing and locking
of vnodes, not using real struct locks for vnode locking, not using
recursive locks when accessing the fronting store, and things like that.
New functionality has been added: unionfs now has mmap() support, but
only partially tested, and rename has been enhanced considerably.
There are still some things that unionfs cannot do. You cannot
rename a directory without confusing unionfs, and there are issues
with softlinks, hardlinks, and special files. unionfs mostly doesn't
understand them (and never did).
There are probably still panic situations, but hopefully no where near
as many as before this commit.
The unionfs in this commit has been tested overlayed on /usr/src
(backing /usr/src being a read-only NFS mount, fronting /usr/src being
a local filesystem). kernel builds have been tested, buildworld is
undergoing testing. More testing is necessary.
lock specifications in kern/vnode_if.src. At present, this do not
distinguish between exclusive and shared locks, and the kernel is so full
of bugs in this area that running with auto-generation of assertions
enabled makes DEBUG_VFS_LOCKS totally useless for anybody that has used it
for anything prior to outputting automated assertions. Due to this, I made
vnode_if.sh only output locking assertions if you have the environment
variable DEBUG_ALL_VFS_LOCKS set to "YES". In order to actually use the
assertions, you need to also add "options DEBUG_VFS_LOCKS" to your kernel
config file.

- Split out the prototypes, externs and struct decls from if_epreg.h into
if_epvar.h.
- Add support for MCA based Etherlink III (3c529) devices.
None of this code is used right now; the old if_ep driver is still
in place and used.
I will eventually get around to converting if_ep_isa.c to newbus once I've
had a talk with Peter and DFR about the DEVICE_IDENTIFY() method.
I have tested this code on my PS/2. It works. I would like EISA and ISA
testers since my example hardware hasn't arrived yet.
Add:
dev/ep/if_ep.c optional ep
dev/ep/if_ep_isa.c optional ep isa
dev/ep/if_ep_eisa.c optional ep eisa
dev/ep/if_ep_mca.c optional ep mca
dev/ep/if_ep_pccard.c optional ep card
to sys/conf/files
Remove:
i386/eisa/3c5x9.c optional ep
i386/isa/if_ep.c optional ep
from sys/i386/conf/files.i386
PCCARD testers wanted!
I will switch off and cvs rm the old driver in favor of this copy once
I've had positive feedback or have the hardware to verify that it works.
