930a65fe47 Use the linux_connect() on alpha rather than passing directly through
to our native connect().  This is required to deal with the differences
in the way linux handles connects on non-blocking sockets.

This gets the private beta of the Compaq Linux/alpha JDK working
on FreeBSD/alpha

8b9d6e94af Enable all interrupts in switch_trampoline after releasing the sched_lock.
This is needed so that kernel threads created before interrupts are
enabled do not run with interrupts disabled once the system is up and
running.

922683e01a Enable linux thread support on the alpha. The guts of linux_clone was
mainly cut-n-pasted from the i386 port, except for the method of setting
the child's stack which is the only MD part of this function.

I've tested with the example apps shipped with the linux threads source
code (ex1-ex6) and with several binary builds of Mozilla.

f16647740e Simplify and correct OSF/1 signal handling.
- No signal translation is needed.  Our signals match the OSF/1 signals
- an OSF/1 sigset_t is 64 bits.  Make certain to use all 64-bits of it.
  We'd previously only used the lower 32 bits.   This was mostly harmless
  as I don't know of an OSF/1 apps which use any signals > 31.  However,
  the alpha Linux ABI uses the osf/1 signal routines and threaded linux
  apps tyically use signals 32 and 33 to comminicate with the manager
  thread, so it is important we preserve the upper 32-bits.

806d7daafe Make MINSIGSTKSZ machine dependent, and have the sigaltstack
syscall compare against a variable sv_minsigstksz in struct
sysentvec as to properly take the size of the machine- and
ABI dependent struct sigframe into account.

The SVR4 and iBCS2 modules continue to have a minsigstksz of
8192 to preserve behavior. The real values (if different) are
not known at this time. Other ABI modules use the real
values.

The native MINSIGSTKSZ is now defined as follows:

Arch		MINSIGSTKSZ
----		-----------
alpha		    4096
i386		    2048
ia64		   12288

328b7df026 Clean this is up a bit for multiple MIDs... We can figure out which MID
for an interrupt to enable/disable from the vector (and GID too, if we
had multiple GIDs)- so, stupidly for now, search for the right mcpcia's
softc so we have the right base address for the bridge CSR to apply
IRQ bit-twiddle's to. Alas- this doesn't yet allow us to run, but it's
the right direction.

6b1d8ceabe Fix CMSG and ALIGN macro usage.
Previously we had to include <machine/param.h> or <sys/param.h> bogusly
due to the fact that <sys/socket.h> CMSG macros needed the ALIGN macro,
which was defined in param.h.  However, including param.h was a disaster
for namespace pollution.
This solution, as contributed by shin a while ago, fixes it elegantly
by wrapping the definitions around some namespace pollution preventer
definitions.
This patch was long overdue.
This should allow any network programmer to use <sys/socket.h> as
before.

John Baldwin
90652ed180 - Modify alpha_setup_intr() to take interrupt handler flags as an additional
argument.  These flags include INTR_FAST, INTR_MPSAFE, etc.
- Properly handle INTR_EXCL when it is passed in to allow an interrupt
  handler to claim exclusive ownership of an interrupt thread.
- Add support for psuedo-fast interrupts on the alpha.  For fast interrupts,
  we don't allocate an interrupt thread; instead, during dispatching of an
  interrupt, we run the handler directly instead of scheduling the thread
  to run.  Note that the handler is currently run without Giant and must be
  MP safe.  The only fast handler currently is for the sio driver.

46aa3347cb Convert all users of fldoff() to offsetof(). fldoff() is bad
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning.  The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

8088699f79 - Overhaul the software interrupt code to use interrupt threads for each
type of software interrupt.  Roughly, what used to be a bit in spending
  now maps to a swi thread.  Each thread can have multiple handlers, just
  like a hardware interrupt thread.
- Instead of using a bitmask of pending interrupts, we schedule the specific
  software interrupt thread to run, so spending, NSWI, and the shandlers
  array are no longer needed.  We can now have an arbitrary number of
  software interrupt threads.  When you register a software interrupt
  thread via sinthand_add(), you get back a struct intrhand that you pass
  to sched_swi() when you wish to schedule your swi thread to run.
- Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit
  more intuitive.  Also, prefix all the members of struct intrhand with
  'ih_'.
- Make swi_net() a MI function since there is now no point in it being
  MD.
