Included <sys/vnode.h> and its prerequisite <sys/proc.h>, and cleaned
up includes. The vop_t changes made the non-inclusion of vnode.h
fatal instead of just sloppy.
i386_bitops.h:
Changed `extern inline' to `static inline'. `extern inline' is a
Linuxism that stops things from compiling without -O. Fixed
idempotency identifier.
Misc:
Added prototypes. Staticized some functions so that prototypes are
unnecessary. Added casts. Cleaned up includes.
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.
The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter. Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.
Handle kdc registration correctly. Catch ISA devices that use eisa
registration and output probe information accordingly.
lsdev will have to be updated to handle EISA devices correctly.
aic7770.c:
Set kdc_isa0 as the parent for 284X cards since its a VL card.
Should anybody out there wonder about this vendetta against global
variables, it is basically to make it more visible what our interfaces
in the kernel really are.
I'm almost convinced we should have a
#define PUBLIC /* public interface */
and use it in the #includes...
This is here now. We can now access (the new) sysctl variables from the
kernel too and using functions to handle access is more sane now.
I will now attack sysctl variables in the rest of the kernel and get them
all converted to newspeak.
Changed vnodep -> vp for consistency with the rest of the kernel, and
changed iparams -> imgp for brevity.
kern_exec.c:
Explicitly initialized some additional parts of the image_params struct
to avoid bzeroing it. Rewrote the set-id code to reduce the number of
logical tests. The rewrite exposed a mostly benign bug in the algorithm:
traced set-id images would get ktracing disabled even if the set-id didn't
happen for other reasons.
cards like the Adaptec 284x that use EISA ID registers for identification
even when in stalled in non-EISA systems.
Use one format throught the files.
-Wall fixes.
earlier discussions with DG, and a recent email exchange with SEF, I
decided to allow UFS to run wide-open on an experimental basis. We
will probably support eventually multiple async modes, and this is
the fastest the we can expect. Just use the -o async flag on the
UFS mount. Good luck...
These functions went away:
enosys (hasn't been used for some time)
enxio
enodev
enoioctl (was used only once, actually for a vop)
if_tun.c:
Continued cleaning up...
conf.h:
Probably fixed the type of d_reset_t. It is hard to tell the correct
type because there are no non-dummy device reset functions.
Removed last vestige of ambiguous sleep message strings.

tty_conf.c:
Cleaned up formatting of tables.
Removed another ARGSUSED for consistency.
conf.h:
Introduced typedefs for line discipline functions.
Backed out most of previous revision (it is done elsewhere).
I've moved the #include <machine/conf.h> inside the #ifdef KERNEL
becuause things like modload #include <sys/conf.h> for the cdevsw definitions
but dont need the conflicting prototype for fdopen in stdio.h and
machine/conf.h.
Bruce may have a better fix for this, but for now I need a make world..
Start the revamp of the initialiation process. New routines include
ahc_alloc, ahc_free, and ahc_reset. These help divide the work of staring
up a board more logically between probe and attach.
ahcintr now takes a (void *) and returns int. The pci code uses it directly.
Until the PCI code for shared edged triggered interrupts is removed, the
eisa code uses a stub (ahc_eisa_intr) that throws away the int returned
by ahcintr.
Use MHz instead of MB/s for printing out sync rates.
Print out "aic7880" instead of "aic7870" for the new aic7880 chips.

some devconf problems. Only the aic7xxx driver will be using this

Adapt aic7770.c to use new eisaconf.
eisadevs.c is replaced by a linker set.

that this exposed. The prototypes should be moved back to the driver

Added idempotency guards to <machine/conf.h>. "ioconf.h" can't be
included when building LKMs so define a wart in bsd.kmod.mk to help
guard against including it.
/dev/random is now a part of the kernel! you will need to make

Fixed the type of pdc_pci_ifintr(). The type of a PCI interrupt handler
is too generic to pass arbitrary struct pointers.
incompatible with the type of a PCI interrupt handler. A new entry
point `ahc_pci_intr()' is used for PCI. ISA and PCI interrupts are
penalized equally (:-) by calling a common handler `ahc_intr()'. This

depending on the contents of our TAO cache. This decision has to be
made once when the connection starts. The earlier code delayed this
decision until the segment was assembled in tcp_output() and
retransmitted SYN segments could have different CC options.

calling (including a soft ISR). ppp_tty.c takes care of the soft masking

(I've discovered that bugs in this area show up within an hour if the
masking was not correct.. :-} This combination has proven stable on

Handling an error condition is inherently more friendly than exploding

line discipline interrupt handlers more or less expect to be called at
spltty() == splimp(), although they have internal splimp()s that are
bogus if this expectation is satisfied. They are called at splsoftty()
from many tty drivers, so they were not protected from being reentered
from their own netisrs. They certainly don't expect that but are
apparently remarkably robust if it occurs. The problem in PR 798 seems
to be caused by pppstart() being reentered and finishing off the output
in progress by following the (stale) sc->sc_outm pointer. Then the
original pppstart() finds garbage in m2 after MFREE(m, m2). slstart()
doesn't have internal state like sc_outm so reentry of it probably only
causes out of order and dropped packets.
