d1693e1701 Back out all the pmap related stuff I've touched over the last few days.
There is some unresolved badness that has been eluding me, particularly
affecting uniprocessor kernels.  Turning off PG_G helped (which is a bad
sign) but didn't solve it entirely.  Userland programs still crashed.

6bd95d70db Work-in-progress commit syncing up pmap cleanups that I have been working
on for a while:
- fine grained TLB shootdown for SMP on i386
- ranged TLB shootdowns.. eg: specify a range of pages to shoot down with
  a single IPI, since the IPI is very expensive.  Adjust some callers
  that used to trigger this inside tight loops to do a ranged shootdown
  at the end instead.
- PG_G support for SMP on i386 (options ENABLE_PG_G)
- defer PG_G activation till after we decide what we are going to do with
  PSE and the 4MB pages at the start of the kernel.  This should solve
  some rumored strangeness about stale PG_G entries getting stuck
  underneath the 4MB pages.
- add some instrumentation for the fine TLB shootdown
- convert some asm instruction wrappers from functions to inlines.  gcc
  seems to do a fair bit better with this.
- [temporarily!] pessimize the tlb shootdown IPI handlers.  I will fix
  this again shortly.

This has been working fairly well for me for a while, but I have tweaked
it again prior to commit since my last major testing round.  The only
outstanding problem that I know of is PG_G related, which is why there
is an option for it (not on by default for SMP).  I have seen a world
speedups by a few percent (as much as 4 or 5% in one case) but I have
*not* accurately measured this - I am a bit sceptical of these numbers.

it.

f2eeb19063 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.

f83fbaf22d Introduce a new option, KVA_SPACE, which can be used to reconfigure
the size of the kernel virtual address space relatively painlessly.
Userland will adapt via the exported kernbase symbol.  Increasing
this causes the user part of address space to reduce.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

268bdb43f9 Optionize UPAGES for the i386. As part of this I split some of the low
level implementation stuff out of machine/globaldata.h to avoid exposing
UPAGES to lots more places.  The end result is that we can double
the kernel stack size with 'options UPAGES=4' etc.

This is mainly being done for the benefit of a MFC to RELENG_4 at some
point.  -current doesn't really need this so much since each interrupt
runs on its own kstack.

2398f0cd1d Hints overhaul:
- Replace some very poorly thought out API hacks that should have been
  fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
  inconvenient temporary ioconf table from config().  We already had a
  fallback to using strings before malloc/vm was running anyway.

65cbb03cfe Added new options CPU_PPRO2CELERON and CPU_L2_LATENCY to support
Socket 8 to 370 converters.  When (1) CPU_PPRO2CELERON option is
defined, (2) Intel CPU is found and (3) CPU ID is 0x66?, L2 cache is
enabled through MSR 0x11e.  The L2 cache latency value can be
specified by CPU_L2_LATENCY option.  Default value of L2 cache latency
is 5.

These options are useful if you use Socket 8 to Socket 370 converter
(e.g. Power Leap's PL-Pro/II.)  Most PentiumPro BIOSs don't enable L2
cache of Mendocino Celeron CPUs because they don't know Celeron CPUs.
These options are needles if you use a Coppermine (FCPGA) Celeron or
PentiumIII, becuase the L2 cache enable bit is hard wired and L2 cache
is always enabled.

80060e8897 Connect the ISA and PCI compatability shims to an option. In this case
it's options COMPAT_OLDISA and COMPAT_OLDPCI.  This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support.  I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.
