a76245d21d This fix allows cards inserted in one of the bottem-most slots on an xp1000
(behind the built-in ppb on hose 1) to be found:

When testing the adaptec controller on alpha, I realized I misread the xp1000
documentation and the way I'm calculating the bus number for PCI
config space accesses on the tsunami is wrong.  I had thought that a bus
behind a ppb should be numbered as the nth bus in that hose, but it
actually needs to be the nth global bus within the system.  The bus number
for the primary bus on a hose must always remain 0 when calculating config
space addresses.

4fc1dda91d Make the fxp driver work on alpha, rather than panic the machine on boot
and/or when using the card.

o Convert the driver to using bus_space.  This allows alphas with
fxp's to boot, rather than panic'ing because rman_get_virtual()
doesn't really return a virtual address on alphas.

o Fix an alpha unaligned access error caused by some misfeature of
gcc/egcs: if link_addr & rbd_addr in the fxp_rfa struct are 32 bit
quantities, egcs will assume they are naturally aligned. So it will do
a ldl & some shifty/masky to twiddle 16 bit values in fxp_lwcopy().
However, if they are 16-bit aligned, the ldl will actually be done on
a 16-bit aligned value & we will panic with an unaligned access
error... Changing their definition to an array of chars seems to fix
this.  I obtained this from NetBSD.

I've tested this on both i386 & alpha.

25cfcb2218 Add ahc driver. The adaptec driver works just dandy on my xp1000 using

is important the ahc driver be in GENERIC so that FreeBSD can install on
these boxes.

535b692091 Unbreak doscmd after the sigset_t change:
doscmd heavily depends on struct sigcontext which luckily is mostly passed
between functions as usion regcontext_t. By redefining union regcontext_t in
terms of mcontext_t almost all bases are covered.

It also seems to me that doscmd was in a transitional state. The redundant
definitions made it difficult to get a clear overview and could easily cause
oversight. To make sure my changes were ok, I went as far as to complete the
transition. It was not exactly necessary, but I expect to have to come back
here some more ("whistle" if I'm wrong :-).

13e14363fe Make FreeBSD less conservative in determining when to return a cookie
error for a directory.  I have made this change after a great deal of
    review although I cannot be absolutely sure that this meets the spec.

    The issue devolves into whether changes in an underlying (UFS) directory
    can cause NFS directory blocks to be renumbered.  My read of the code
    indicates that NFS directory blocks will not be renumbered, which means
    that the cookies should still remain valid after a change is made to
    the underlying directory.  This being the case, a cookie error should
    not be returned when a change is made to the underlying directory and,
    instead, the NFS client should rely on mtime detection to invalidate and
    reload the directory.

    The use of mtime is problematic in of itself, due to insufficient
    resolution, which is why I believe the original conservative error
    handling was done.  Still, there have been dozens of bug reports by
    people needing solaris<->FreeBSD interoperability and these have to
    be accomodated.

3cf3c5d9dd sigset_t change (part 5 of 5)
-----------------------------

Most of the userland changes are in libc. For both the alpha
and the i386 setjmp has been changed to accomodate for the
new sigset_t. Internally, libc is mostly rewritten to use the
new syscalls. The exception is in compat-43/sigcompat.c

The POSIX thread library has also been rewritten to use the
new sigset_t. Except, that it currently only handles NSIG
signals instead of the maximum _SIG_MAXSIG. This should not
be a problem because current applications don't use any
signals higher than NSIG.

There are version bumps for the following libraries:
  libdialog
  libreadline
  libc
  libc_r
  libedit
  libftpio
  libss

These libraries either a) have one of the modified structures
visible in the interface, or b) use sigset_t internally and
may cause breakage if new binaries are used against libraries
that don't have the sigset_t change. This not an immediate
issue, but will be as soon as applications start using the
new range to its fullest.

NOTE: libncurses already had an version bump and has not been
      given one now.

NOTE: doscmd is a real casualty and has been disconnected for
      the moment. Reconnection will eventually happen after
      doscmd has been fixed. I'm aware that being the last one
      to touch it, I'm automaticly promoted to being maintainer.
      According to good taste this means that I will receive a
      badge which either will be glued or mechanically stapled,
      drilled or otherwise violently forced onto me :-)

NOTE: pcvt/vttest cannot be compiled with -traditional. The
      change cause sys/types to be included along the way which
      contains the const and volatile modifiers. I don't consider
      this a solution, but more a workaround.

956d3333ca sigset_t change (part 4 of 5)
-----------------------------

The compatibility code and/or emulators have been updated:

iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.

Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.

A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.

The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.

91078fca0c sigset_t change (part 3 of 5)
-----------------------------

By introducing a new sigframe so that the signal handler operates
on the new siginfo_t and on ucontext_t instead of sigcontext, we
now need two version of sendsig and sigreturn.

A flag in struct proc determines whether the process expects an
old sigframe or a new sigframe. The signal trampoline handles
which sigreturn to call. It does this by testing for a magic
cookie in the frame.

The alpha uses osigreturn to implement longjmp. This means that
osigreturn is not only used for compatibility with existing
binaries. To handle the new sigset_t, setjmp saves it in
sc_reserved (see NOTE).

the struct sigframe has been moved from frame.h to sigframe.h
to handle the complex header dependencies that was caused by
the new sigframe.

NOTE: For the i386, the size of jmp_buf has been increased to hold
      the new sigset_t. On the alpha this has been prevented by
      using sc_reserved in sigcontext.

2c42a14602 sigset_t change (part 2 of 5)
-----------------------------

The core of the signalling code has been rewritten to operate
on the new sigset_t. No methodological changes have been made.
Most references to a sigset_t object are through macros (see
signalvar.h) to create a level of abstraction and to provide
a basis for further improvements.

The NSIG constant has not been changed to reflect the maximum
number of signals possible. The reason is that it breaks
programs (especially shells) which assume that all signals
have a non-null name in sys_signame. See src/bin/sh/trap.c
for an example. Instead _SIG_MAXSIG has been introduced to
hold the maximum signal possible with the new sigset_t.

struct sigprop has been moved from signalvar.h to kern_sig.c
because a) it is only used there, and b) access must be done
though function sigprop(). The latter because the table doesn't
holds properties for all signals, but only for the first NSIG
signals.

signal.h has been reorganized to make reading easier and to
add the new and/or modified structures. The "old" structures
are moved to signalvar.h to prevent namespace polution.

Especially the coda filesystem suffers from the change, because
it contained lines like (p->p_sigmask == SIGIO), which is easy
to do for integral types, but not for compound types.

NOTE: kdump (and port linux_kdump) must be recompiled.

Thanks to Garrett Wollman and Daniel Eischen for pressing the
importance of changing sigreturn as well.

da3605dbea sigset_t change (part 1 of 5)
-----------------------------

Rename sigaction, sigprocmask, sigpending and sigsuspend to
osigaction, osigprocmask, osigpending and osigsuspend (resp)
and add new syscalls for them to support the new sisgset_t
without breaking existing binaries.

Change the prototype of sigaltstack to use the typedef stack_t
instead of struct sigaltstack to reflect that it is SUSv2
compliant.

Also, rename sigreturn to osigreturn and add a new syscall
to support the modified stackframe. The change is caused by
sigreturn operating on ucontext_t now and the fact that
siginfo_t has been updated to conform to SUSv2.
