but isn't valid.
Reimplement pmap_remove() to be much more efficient at removing large
stretches of addresses.
As part of reimplementing pmap_remove() fix pmap_protect() so that it stands
a hope of working.
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386. This is a stopgap with a
hopefully limited lifetime.

Callers only need to initialize d_secperunit now, but should
initialize d_type (to reduce the IDE/SCSI confusion), d_typename
(put the disk model in it) and geometry info (if it isn't completely
ficticious). Callers will soon need to initialize d_secsize.
normally only defined in opt_devfs.h, so testing it before including
anything is normally a no-op. Undef'ing DEVFS before including
opt_devfs.h is similarly useless. OTOH, DEVFS support for sliced

(if there are no such devices, then nothing in this file is used)
or necessary (otherwise). It even seems to work for sliced cd
devices.
small part of a bug suite beginning in the SLICE probes but mostly in the
floppy driver. This is a quick fix: the auto case shouldn't be special;
DMA should also be stopped in isa_dma_release(); isa_dmastop() probably
shouldn't exist; common DMA registers should not be accessed without
locking.
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case. This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested. The fix is simply to arrange to reset the state
machine.
Corruption of the buffer queue seems to only have been a problem in the
floppy driver. Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order. Dequeueing breaks it anyway.
These asm statments are not quite as pessimal as when I complained
about them in rev.1.9 of audio.c. They seem to be only 40% slower
than the C version on P5's and the same speed on K6's.

printf format broken by this. The old math emulator now compiles
cleanly on i386's with 64-bit longs. It may even work, provided
suword() doesn't actually write a long.
nearly so many casts here. Casting an pointer that was an integer
back to an integer just to compare it with -1 is bad, and casting
it back just to compare it with NULL is just wrong.
Access the entry address as a uintfptr_t, not as a long, and not
necessarily as what modload(8) passes (it takes a u_long from the
exec header and passes a u_int).
Fixed bitrot in K&R support (suword() now takes a long word).
Didn't fix corresponding bitrot in store.9 and fetch.9.
The correct types for the store and fetch families are problematic.
The `word' functions are unfortunately named and need to be split
to handle ints/longs/object pointers/function pointers. Storing
argv[] as longs is quite broken when longs are longer than pointers,
but usually works because it clobbers variables that will soon be
reinitialized.
Hopefully caddr_t is large enough to hold function pointers.
Cast object pointers to uintptr_t before casting them to u_long.
Types are wronger than usual for the PT_READ_U case. ptrace() can
only return ints, but longs are accessed.

u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

Don't cast pointers to integers just to do ordinary pointer arithmetic

Added corresponding signed type (intptr_t). Changed/added

use nonstandard types to implement these types, and don't comment
on them in <machine/types.h>.
cure the problems I was having with interrupts not being acknowledged
on time. This fixes a problem I observed where starting two ping -f
processes at 10Mbps would cause an adapter check due to TX GO commands
being issued before TXEOC interrupts were being acked.
Also fix a small problem with tl_start(): the mechanism I was using
to queue new packets onto the TX chain was bogus.
Change adapter check handler so that it resets card state after
tl_softreset() is stored.
Moved all EEPROM-related macro definitions into if_tlreg.h.
Don't allow an autoneg session to start until after the TX queue has
been drained, and don't transmit anything until after the autoneg
session is complete.
Also add support for two more Compaq ThunderLAN-based cards, and three
cards from Olicom which also use the ThunderLAN chip. The only thing
different about the Olicom cards is that they store the station address
at a different location within the EEPROM.
`len = min(so->so_snd.sb_cc, win) - off;'. min() has type u_int
and `off' has type int, so when min() is 0 and `off' is 1, the RHS
overflows to 0U - 1 = UINT_MAX. `len' has type long, so when
sizeof(long) == sizeof(int), the LHS normally overflows to to the
correct value of -1, but when sizeof(long) > sizeof(int), the LHS
is UINT_MAX.
Fixed some u_long's that should have been fixed-sized types.

match the function definition lexically, and still depends on a
gcc feature to match if ints have more than 32 bits).
sizeof(struct bpf_hdr) > 20. 20 is normal on 32-bit systems with
32-bit alignment, but we still assume that the last 2 bytes of the
struct are unnecessary padding on such systems. On systems with
64-bit longs, struct timeval is bloated to 16 bytes, so bpf headers
certainly don't fit in 18 bytes.

Use them to `make gcc -Wformat' check formats for all printf-like

The size mismatch did not matter due to sufficient padding at the end
of the structure that holds time stamps (there is an unused member).
The fix suggested by Bruce Evans used "sizeof (ticks_t)", but I prefer
to use "sizeof ticks", and didn't seem to object in his last mail on
this topic.

and these don't depend on profiling flags).
Give an explicit rule for building vnode_if.o. This fixes building
it without ${PROF}.
Use .ORDER instead of a stamp file to avoid building vnode_if.[ch]
concurrently.
Removed explicit dependencies that will be generated by `make' (.c.o)
or will be generated by mkdep.
Added missing dependencies of special objects on opt_global.h.
Use ${NORMAL_C} instead of special rules for special objects where
possible.
