d4548c1c49 A slap on the wrist to Dag-Erling, who plainly did not test this before
committing it.  There was a large syntax error at line 404 which could
not possibly have allowed compilation. :)

39d6cd0751 Stop physical DMA for the non-auto case in isa_dmadone(). This fixes a
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.

7466f92c1a Fixed error handling after a seek error that can't happen. When the
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

than the C version on P5's and the same speed on K6's.

1dc298263b SLICE probing becomes asynchronous. It can now be triggered by
interupt level events. This needs a lot of cleanup, but has been working
here for a month or two.. originally needed for CAM integration
but that hasn't happenned yet. The probing  state machines for each
handler should be replaced by a more generic state-service. It's
still quite messy in there..

1bcbd442a2 Removed historical dependencies on `Makefile'. They had rotted to being
mostly for objects that have the fewest dependencies on `Makefile'
(since they were mostly for utilities and objects generated from *.s
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.

d307f5bacf Don't pretend to support ix86's with 16-bit ints by using longs
just to ensure 32-bit variables.  Doing so broke and/or pessimized
i386's with 64-bit longs (unnecessary use of 64-bit variables
caused remarkably few problems in C code, but the inline asm here
tended to fail because there are no 64-bit registers).  Since the
interfaces here are very machine-dependent and shouldn't be used
outside of the kernel, use a standard types of "known" width instead
of fixed-width types.

Changed all quad_t's to u_int64_t's.  quad_t isn't standard, and
using signed types for 64-bit registers was bogus (but made no
difference).

63dd5b520f Added a kernel-only typedef (ptrint_t) giving an integral type that is
least unsuitable for holding an object pointer.  This should have been
used to fix warnings about casts between pointers and ints on alphas.

Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>.  Kludged libc/gmon/mcount.c so that it can
still see this typedef.

0262543b5f There is no such thing any more as "struct bdevsw".
There is only cdevsw (which should be renamed in a later edit to deventry
or something). cdevsw contains the union of what were in both bdevsw an
cdevsw entries.  The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).

rawread()/rawwrite() went away as part of this though it's not strictly
the same  patch, just that it involves all the same lines in the drivers.

cdroms no longer have write() entries (they did have rawwrite (?)).
tapes no longer have support for bdev operations.

5ffa52e68e Add workaround to allow the FreeBSD boot block to work on
Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'

This workaround has no effect on the boot sector code other than to
increase its size by three bytes.

406115eeb3 These are a selection of small problems and annoyances with the netboot
code. Apart from the first one, none really affect typical configurations
but are nevertheless unnecessary limitations. We use netbooted PCs as
student X-terminals and all of the below fixes have been useful. Apologies
for including them all in one PR, but some are just too silly or trivial
to send on their own!

a)     Newer SMC cards have hardware addresses starting with 00:E0.
      Netboot compares the MAC address with 00:00:C0 to determine
      if it is a WD/SMC card, so it fails to detect these.

b)     Netboot is unable to boot kzipped kernels, as it assumes that
      the kernel load address is 0x100000.

c)     Users can abort the booting process and enter arbitrary network
      addresses, or boot from a floppy disk. This can be a problem when
      netbooted machines are used in a student environment.

d)     It is not possible to set all options via bootp. For example there
      is no way to remotely force a client to boot from disk. With both
      SECURE_BOOT(patch below) and NO_TFTP defined, short of unplugging
      the eprom there is no way at all to get the client to boot locally.
      A generic solution is to allow complete netboot commands to be sent
      using bootp lines such as:
	      :T132="diskboot":
e)     The last character of netboot command names is not checked. You
      can type 'iz 10.0.0.1' and it will be interpreted as 'ip'. This
      is only important if you try to add a new command which is the
      same as an existing one except for the last character.

f)     We have a configuration where multiple servers are willing to serve
      a diskless client. The tftp config file, or the bootptab entry on
      each server must specify the root and swap filesystems as 'ip:/fs'
      even though 'ip' will usually be the responding server's IP address.
      It would be nice if netboot could automatically prepend the server's
      IP address to an entry specified as just '/fs', so that multiple
      servers can use the same tftp or bootp configuration files. Admittedly
      this is hardly a major problem!
