It doesn't have to be changed, but since it's cleaner to keep the type

to be a caddr_t, but since it's being passed constant user argument pointers
it needs to be const, and since it's being passed a variety of argument
pointer types it makes sense to change it to void *. That argument is
simply being handed to copyin().

__builtin_classify_type() into harmless values, so that lint doesn't
get confused, think they're real functions, and that they're being
invoked in the wrong ways.
* change in-kernel syscall prototypes to match user-land prototypes in
the following ways:
+ add 'const' where appropriate.
+ make the following "safe" type changes where appropriate:
caddr_t -> struct msghdr *
caddr_t -> struct sockaddr *
caddr_t -> void *
char * -> void *
int -> uid_t (safe because uid_t not used as index/count)
int -> gid_t (safe because gid_t not used as index/count)
u_int -> size_t
+ change "int" to "u_long" in flags arguments to chflags() and
fchflags(). This is safe because the arguments are used as
flag bits and there's nothing that would cause the top bit
of the int to be set yet, and because the user-land definitions
already specified u_long, so a u_long's worth of argument was
already being passed in.
wrong for a bunch of functions:
void: sys_exit, sys_sync
ssize_t: sys_read, sys_write, sys_recvmsg, sys_sendmsg,
sys_recvfrom, sys_readv, sys_writev, sys_sendto
long: sys_pathconf, sys_fpathconf
void *: sys_shmat
* Note that sys_open, sys_ioctl, and sys_fcntl are defined such that their
last argument is optional.
These changes should not have any real effect, because right now this
information is not actually used for anything.
* Don't output prototypes for INDIR syscalls (since they always show up as
sys_nosys() in the syscall table).
* Add "indir" to the comment for INDIR syscalls in the syscalls table, so
it's more obvious why they call sys_nosys().
* Deal with multi-word system call return types (i.e. foo *, or
struct foo *, or struct foo, etc.).
* Add a new class of system calls "INDIR" (for "indirect"), which
is to be used to represent indirect syscalls like syscall() and
__syscall() which are implemented in MD code and which don't want
args structures defined. (The old way of declaring this type of
syscalls still works.)
* Allow system calls to be marked as having a variable number of
arguments, by inserting "..." (no trailing comma) before the
first hf the optional arguments in the syscall definition. Because
of the way syscall arguments are handled by MI code, _ALL_ syscall
arguments must actually be included in the definition, i.e.
"optional" arguments are either "are there or aren't," i.e. these
aren't really varargs functions. Therefore, for normal syscalls,
there _must_ be arguments listed after the "...". For INDIR
syscalls, which really do have a variable number of arguments and
which aren't handled via the normal mechanism, that requirement is
not in force.
* output primitive (machine-parsable) syscall descriptions as comments
in <sys/syscall.h>. These can be used to easily build real function
prototypes, or to build stub functions for use by lint.
- Always allow RAW_PART to be opened, regardless of the partition table.
- Never do partition translation on RAW_PART; it's always offset 0.
- Always make sure the disklabel is read from RAW_PART.
- Make *strategy() return values consistent.
This fixes a condition where a bogus partition table could be written
to the disk from SYS_INST, and the user had no way to rewrite with
a correct partition table, since RAW_PART would be invalid.

This change should smooth pr 2890 by Thorsten Frueauf (also privately

paranoically high delay() calls in the grf_cl initialization, it was made
even more visible by the miscalibrated (to the save side) new style delay
loop.

We're about 75% there. SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.
New config glue is enabled with the "NEWCONFIG" kernel option. If that
option is not present, an old config kernel will be built. Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.

bus_scan() and bus_print(), and move bus_peek() and bus_mapin() to the
NuBus code (since they'll eventually go away, anyway).
Because there is no way yet to tell init(1) to execute commands before
single user-mode is entered, the inittodr() function is still partly
functional. It retrieves the value of the RTC and sets the time as if
the RTC was running at UTC. The resettodr() function is a No-Op. The
RTC can only be changed by a write to /dev/rtc.
The TIMEZONE and DST options are no longer needed and removed from the
config files.
using __weak_alias in libc, __indr_reference should probably be defined
to do nothing (but defined, so that duplicate functions/variables aren't
compiled). However, when not using __weak_alias, __indr_reference causes
them to be omitted completely, which is a lose. So, until weak aliases
are going to be used, don't define __weak_alias or __indr_reference.

Add newline to `Interface disabled' printf and clean up formatting.
Change packet read/write code to align all reads and writes into
memory to an appropriate boundary for the I/O size. This also fixes
a bug where the trailing unaligned bytes (1-3 of them) would be
put in an additional mbuf even if there was enough space for them
in the one we were currently filling.
This has been tested on a 3c905 in an Alpha (32-bit I/O, alignment
required), a 3c905 in an i386 (32-bit I/O, alignment not required)
and a 3c509 in an i386 (16-bit I/O, alignment not required). It
should be tested on a 3c509 in an Alpha with an ISA bus, if somone
can manage to get the two items together.
There are still some bugs in the driver relating to initialisation;
on my Alpha with a 3c905 you need to do an `ifconfig ep0 down;
ifconfig ep0 up' after the initial ifconfig to make it start working.
Apparently there are also some problems with a 3c579 in an i386,
although a 3c905 in an i386 works just fine.

XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.

Problem noted in PR #1308 (Kenneth Stailey) and PR #1780 (Chris Demetriou).
Fix suggested in PR #1780 by Chris Demetriou, and munged a bit by me,
and OK'd by Frank van der Linden <fvdl@netbsd.org>.
Improve the queuing algorithms used by NFS' asynchronous i/o. The
existing mechanism uses a global queue for some buffers and the
vp->b_dirtyblkhd queue for others. This turns sequential writes into
randomly ordered writes to the server, affecting both read and write
performance. The existing mechanism also copes badly with hung
servers, tending to block accesses to other servers when all the iods
are waiting for a hung server.
The new mechanism uses a queue for each mount point. All asynchronous
i/o goes through this queue which preserves the ordering of requests.
A simple mechanism ensures that the iods are shared out fairly between
active mount points.

This should eventually be replaced by attachment code for the normal
