Disallow wait options that are not a combination of the standard POSIX
options WUNTRACED and WNOHANG, as is required by POSIX. BSD doesn't
have any extensions here, but the code was `#ifdef notyet' for some
reason.
interval [VM_MIN_KERNEL_ADDRESS, etext] was used instead of
[btext, etext). Added a comment about this being completely
wrong for LKMs. This only affects interpreting the instructions
after the return to attempt decide the number of args. The
attempt usually fails anyway.
checking was mostly wrong at the boundaries. For the lower limit,
VM_MIN_KERNEL_ADDRESS was used instead of btext and there was an
off-by-(`size' - 1) error. For the upper limit, &etext was used
instead of etext and there was an off-by-1 error. The bugs were
harmless because `size' is not too large and some memory is mapped
just beyond the ends. We still depend on the former to avoid
having to handle the case where the memory range covers the whole
text section, and on the latter to prevent problems when we map
just beyond an end to allow writing an address range that overlaps
the end.
Fixed placement of a nearby comment.
one traditionally reserved for swap devices. The restrictions
should now be the same as the ones for dumpsys(). The restriction
on the partition should be removed someday, and dumpsys() shouldn't
repeat all the checks.
it if the file system is mounted noatime). Not fixed: the access
time is marked at the start of a read() and not marked on successful
completion. I think this should be handled at the vfs level.
Print a better panic message for missing vops. Don't use printf()
before panic(), since the printf()ed part isn't shown by gdb.
This actually loses a little with the current gdb, since gdb just
prints the fmt arg to panic, so %'s aren't expanded. gdb should
fetch the full message from the message buffer if possible.
Fixed default vop function for vop_getpages_desc. It needs to
just return EOPNOTSUPP so that the vnode pager can get the pages
in using a general method. Panicing broke exec'ing of files on
ext2fs file systems. ffs works because it doesn't use the default.
Fixed nearby style bugs.
Fixed nonblocking mode. It was per-device instead of per-file. This
also fixes clobbering of bd_rtout by overloading it to hold a wrong
version of the blocking flag. I hope nothing depends on the bugs.

Don't depend on gcc's misfeature of rewriting char args in old-style
function definitions to match wrong prototypes. Break K&R1 support
to fix this quickly.
Testing in if_ppp.c is good enough.
Added comments about bogus #includes and #defines.
Removed unused #includes.
Don't depend on gcc's misfeature of rewriting short args in old-style
function definitions to match wrong prototypes. I just changed the
function definition to match the prototype, since this is easy to
verify automatically (it causes no changes in the object code), but
it breaks K&R1 support and doesn't fix the pessimal type.
Use gettime() instead of microtime() to set if_lastchange for i/o's.
microtime() is probably too expensive. However, setting if_lastchange
for i/o's may be wrong.
volatile to use outside of splclock(). microtime() is probably too
expensive to use for every i/o. However, setting ifi_lastchange for
every i/o is just wrong according to the comment about ifi_lastchange
in <net/if.h>. It is set then for atm, fddi and the latest version
of ppp.)
and don't include <sys/fcntl.h>. (The select -> poll changes replaced
fcntl macros by poll macros.)
Use <machine/*.h> instead of <i386/include/*.h>.
Fail the probe instead of crashing in the unlikely event that malloc()
fails.
Fixed #include order. <i386/isa/isa_device.h> will soon be a prerequisite
for <i386/isa/pnp.h>. Including both in alphebetical order gets this
right naturally.
