26f336a8a2 Back out previous revision. TCBHASHSIZE isn't an option, despite what I'd
been misled to believe by unknown parties.  It probably *should* be an option,
but the runtime value is controlled by a tunable, which Ought To Be Enough.

c2ef36c585 Deleted most of npxprobe(), and merged npxprobe1() back into npxprobe().
Use the normal interrupt handler (npx_intr()) instead of a special
probe-time interrupt handler, although this causes problems due to
the bus_teardown_intr() not actually even tearing down the interrupt
(these problems were avoided by doing interrupt attachment for the
special interrupt handler directly).  Fixed minor bitrot in comments.

The reason for the npxprobe()/npxprobe1() split mostly went away at
about the same time it was made (in 1992 or 1993 just before the
beginning of history).  386BSD ran all probes with interrupts completely
masked, and I didn't want to disturb this when I added an irq probe
to npxprobe().  An irq (not necessarily npx) must be acked for at least
external npx's to take the cpu out of the wait state that it enters
when an npx error occurs, so the probe must be done with a suitable
irq unmasked.  npxprobe() went to great lengths to unmask precisely
the npx irq.

Running probes with all interrupts masked was never really needed in
FreeBSD, since FreeBSD always masked interrupts well enough using
splhigh(), but it wasn't until rev.1.48 (1995/12/12) of autoconf.c
that all probes were run with CPU interrupts enabled.  This permits
npxprobe() to probe its irq using normal interrupt resources.  Note
that most drivers still can't depend on this.  It depends on the
interrupt handler being fast and the irq not being shared.

d5d14ab023 Commit my old fixes for cosmetic bugs in npxprobe() so that they aren't
lost when the buggy code goes away completely:
- don't assume that the npx irq number is >= 8.  Rev.1.73 only reversed
  part of the hard-coding of it to 13 in rev.1.66.
- backed out the part of rev.1.84 that added a highly confused comment
  about an enable_intr() being "highly bogus".  The whole reason for
  existence of npxprobe() (separate from the main probe, npxprobe1())
  is to handle the complications to make this enable_intr() safe.
- backed out the part of rev.1.94 that modified npxprobe().  It mainly
  broke the enable_intr() to restore_intr().  Restoring the interrupt
  state in a nested way is precisely what is not wanted here.  It was
  harmless in practice because npxprobe() is called with interrupts
  enabled, so restoring the interrupt state enables interrupts.  Most
  of npxprobe() is a no-op for the same reason...

b5831c2530 Correct the input/output/clobber specifications for the cpuid
instruction.  Stefan Keller <dres@earth.serd.org> noticed that CPU
identification was broken when compiled with -O2, and tracked it
down to the asm statement, which was storing values into memory
without specifying that memory was modified.  He submitted a patch
which added "memory" as a clobber, but I refined it further to
arrive at this version.

478926021c Remove the Xresume* labels from the i386 interrupt handlers; the
code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.

Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

29c5c858fc Dissociate ptrace from procfs.
Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested.  Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.

This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().

It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".

c0f87bdb16 Rewrite the pc98 bus_space stuff.
The type of bus_space_tag_t is now a pointer to bus_space_tag structure,
and the bus_space_tag structure saves pointers to functions for direct
access and relocate access.

Added bsh_bam member to the bus_space_handle structure, it saves access
method either direct access or relocate access which is called by
bus_space_* functions.

Added the mecia device support. If the bs_da and bs_ra in bus tag are set
NEPC_io_space_tag and NEPC_mem_space_tag respectively, new bus_space stuff
changes the register of mecia automatically for 16bit access.

TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
