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.
attribute. It is like the existing "printf" archetype, except that
it doesn't complain if the format string is a null pointer. See
the node "Function Attributes" in the GCC info pages if you don't
know what this is all about.
This change will allow us to add format string checking for the
err(3) family of functions.
respectively. Most of the longs should probably have been
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.
FreeBSD does not have _POSIX_SAVED_IDS enabled. Thanks to Warner Losh
and Ollivier Robert for pointing this out, and Bruce Evans for explaining
the role of _POSIX_SAVED_IDS.
casting them to long, etc. Fixed some nearby printf bogons (sign
errors not warned about by gcc, and style bugs, but not truncation
of vm_ooffset_t's).

Use slightly less bogus casts for passing pointers to ddb command
functions.
to [u]intptr_t instead of to [u_]long.
Don't cast pointers to integers just to do ordinary pointer arithmetic
on them, especially when the casts use gcc's feature of casting lvalues.
them as ints. Among other bugs, doing so at best caused benign
overflow followed by fatal sign extension on machines with 32-bit
ints and 64-bit longs.
suitable for holding object pointers (ptrint_t -> uintptr_t).
Added corresponding signed type (intptr_t). Changed/added
corresponding non-C9x types for function pointers to match. Don't
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.
mismatches exposed by this (the prototype for tcp_respond() didn't
match the function definition lexically, and still depends on a
gcc feature to match if ints have more than 32 bits).
