700146fa73 DA (scsi) and AD (ata) diskdrivers:
Make the dump routine do just writing of data.

1fbee2b785 Add a new #include which describes the common header format for kerneldumps.
This design is my best effort and it is quite likely that people more used
to kernel dumps may want to change this subsequently so two levels of
version numbers are provided: one for the common header and one per
architecture.

8fdb202d85 Support more than 32 sio unit numbers. The maximum unit number is now
(65536 * 32 - 1), but MAKEDEV only supports up to (32 * 32 -1).  Device
names use the unit number in base 32 for all "digits".

This required fixing an old bug in MAKEDEV:ttyminor().  Its arg was the
global $unit instead of $1.

e968c4ef3c Hacks for measuring interrupt latency. Interrupt latency can be
measured accurately for periodic interrupts provided the interrupts
don't need to be serviced very quickly to keep their period almost
constant.  sio output interrupts have this property (interrupt service
can be delayed for up to 1 character time without the period changing).

This is non-optional and undocumented so that it can be added and
removed easily.  It has no significant effect unless it is enabled by
hacking on a variable using a debugger.  Hardclock and statclock interrupts
would work even better for this, at least on i386's, provided their
interrupt handlers are fast (as they are in -current but not in -stable
or in my version of -current).

ca19a2d68c Implement i386's (o)sigreturn() like the alpha's: Use copyin() to read
the osigcontext or ucontext_t rather than useracc() followed by direct user-
space memory accesses.  This reduces (o)sigreturn()'s execution time by 5-
50%.

cd2c8e3ef6 Pass the address of the bootinfo block to the kernel in register

12ae303a12 Transition to a model where the loader passes the address of the
bootinfo block in register r8. In locore.s we save the address
in the global variable 'pa_bootinfo'. In machdep.c we compare
this value against the hardwired address, but don't depend on its
validity yet (ie: we still expect the bootinfo block to be at the
hardwired address). After a small amount of time, we'll flip the
switch and depend on the loader to pass us the address. From that
moment on the loader is free to put it anywhere it likes, provided
the machine itself likes it as well.

Add some verbosity to aid in the transition. We emit a message if
the loader didn't pass the address and we also emit a message if
there's no bootinfo block at the hardwired address.

While in locore.s, reduce the number of redundant serialization
instructions. A srlz.i is a proper superset of a srlz.d and thus
is a valid replacement. Also slightly reorder the movl instructions
to improve bundle density.

c459265de7 Pass the physical address of the bootinfo block to the kernel in
register r8. We continue to write the bootinfo block at the same
hardwired address, because the kernel still expects it there.
It is expected that future kernels use register r8 to get to the
bootinfo block and don't depend on the hardwired address anymore.

Bump the loader version once again due to the interface change.

4f1f485f34 Fixed handling of short reads in readdisklabel() and writedisklabel().
These functions use DEV_STRATEGY() which can easily return a short
count (with no error) for reads near EOF.  EOF happens for "disks" too
small to contain a label sector (mainly for empty slices).  The functions
didn't understand this at all, and looked for labels in the garbage
in the buffer beyond what DEV_STRATEGY() returned.  The recent UMA
changes combined with my local changes and configuration resulted in
the garbage often containing a valid but garbage label left over from
a previous call.

Bugs in EOF handling in -current limited the problem to "disks" with
size precisely LABELSECTOR sectors.  LABELSECTOR happens to be a very
unusual "disk" size since it is only 0 for non-i386 arches that don't
usually have disks with DOS MBRs.

0508986cce In ffs_mountffs(), set mnt_iosize_max to si_iosize_max unconditionally
provided the latter is nonzero.  At this point, the former is a fairly
arbitrary default value (DFTPHYS), so changing it to any reasonable
value specified by the device driver is safe.  Using the maximum of
these limits broke ffs clustered i/o for devices whose si_iosize_max
is < DFLTPHYS.  Using the minimum would break device drivers' ability
to increase the active limit from DFTLPHYS up to MAXPHYS.

Copied the code for this and the associated (unnecessary?) fixup of
mp_iosize_max to all other filesystems that use clustering (ext2fs and
msdosfs).  It was completely missing.

a918e110c4 Add a quick and dirty way to determine where we're loaded from. We
only care if it's network or not at this time. If we're loaded from
the network, we set currdev (=loaddev) so that the kernel is loaded
from the network as well. In all other cases we initialize to disk.
This makes netbooting more convenient and can easily be enhanced to
do more elaborate checking.

4e357dbc58 The EFI loader has been improved a lot since it was first added.
Most significantly (from an interfacing point of view) is the
support for the FPSWA pointer passing. Even though that was added
4 months ago, it's probably not a bad idea to bump the version
number to reflect this.

7608f7cb80 Fix the initialization of the protocol:
o  Query the state field of the protocol mode to determine whether
   we need to start and/or initialize the protocol. When we're
   loaded across the network, the protocol has already been started
   and is already initialized. When no networking has happened yet,
   we have to start and initialize the protocol ourselves.
o  After initialization, we have to set the receive filters. Not
   doing this results in a deaf interface. We set the unicast and
   broadcast filters. Multicast may not be supported. This specific
   change fixes the problem we had that we could not netboot if
   the loader was started from the EFI shell.
o  To help future debugging, add a function that dumps the current
   mode of the interface. It's conditional on EFINET_DEBUG.
o  To help in runtime problems, emit a diagnostic message when we
   could not initialize the protocol properly.

c61a2c84f0 Don't blindly dereference f->f_devdata as if it's always a pointer to
an efi_devdesc structure. When we're netbooting, f->f_devdata holds
the address of the network socket variable. Dereferencing this caused
some very unpredictable behaviour, including proper functioning.
So, as a sanity check, we first make sure f->f_dev points to our
own devsw. If not, the open will fail before we use f->f_devdata.

This solves the netboot hangs I invariably got whenever I used the
latest toolchain to compile the EFI loader.

9423456018 o Make efinet_put a blocking call by waiting for the protocol
layer to signal transmission of the packet. This resolves the
   problem I'm seeing that an immediate call to net->Receive
   after calling net->Transmit returns EFI_DEVICE_ERROR. This
   condition seems to be sufficiently persistent that BOOTP and
   RARP fail.
o  While here, unify all functions to have 'nif' defined. Some
   have it as arguments. The others now have them as locals. We
   now always get the protocol interface by using the 'nif' var.

The current status of netbooting is that even though we now reliably
have BOOTP working (again), opening a file (ie loading a kernel)
across the network causes the loader to hang. I'm working on that now.

ede9f03a1a Fix the beforeinstall target. We install ${PROG}.help if loader.help
exists, otherwise we install it anyway. I interpret this as a very
high desire to install ${PROG}.help. Alas, ${PROG}.help doesn't exist
at the moment and neither does loader.help, so in practice this just
doesn't work, no matter how you interpret it. The compromise is to
install ${PROG}.help IFF it exists. I realize we lost creativity with
this commit, but style should have been preserved, AFAICT :-)
