if we have to bounce a buffer, clear our anything already setup in
the map before trying again.

riastradh@ noticed that a map had two types of mbuf types, and this
seems to avoid it as seen on eqos(4) on quartz64.

add a couple more event counts for bus dma events.

ok @skrll @raistradh @jmcneill

A few bus_dmatag_subregion fixes

- return EOPNOTSUPP if min_addr isn't less than max_addr
- fix the subset check to ensure that all the ranges in the parent tag are
  within the {min,max}_addr range.  If so we can just continue to use the
  parent tag.
- when building the new ranges read the parent tag range rather than un-
  initialised memory.
- remove the max_addr != 0xffffffff check - the overflow should be handled
  by the unsigned arithmetic for arm32.
- add a KASSERT
- add comments

Resolve a couple of conflicts (result of the uimin/uimax changes)

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Pullup from HEAD:
On Cortex, speculative loads can cache lines to be populated after then they've
been invalidated for a DMA read.  So after the DMA read we have to reinvalidate
them again.  We have to both invalidates since the former prevents dirty lines
overwriting just DMAed data.

errant code being generated but I'll look at that later by comparing the diff

at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through

Add the generic arm32 bits of the new pmap, contributed by Wasabi Systems.

Some features of the new pmap are:

 - It allows L1 descriptor tables to be shared efficiently between
   multiple processes. A typical "maxusers 32" kernel, where NPROC is set
   to 532, requires 35 L1s. A "maxusers 2" kernel runs quite happily
   with just 4 L1s. This completely solves the problem of running out
   of contiguous physical memory for allocating new L1s at runtime on a
   busy system.

 - Much improved cache/TLB management "smarts". This change ripples
   out to encompass the low-level context switch code, which is also
   much smarter about when to flush the cache/TLB, and when not to.

 - Faster allocation of L2 page tables and associated metadata thanks,
   in part, to the pool_cache enhancements recently contributed to
   NetBSD by Wasabi Systems.

 - Faster VM space teardown due to accurate referenced tracking of L2
   page tables.

 - Better/faster cache-alias tracking.

The new pmap is enabled by adding options ARM32_PMAP_NEW to the kernel
config file, and making the necessary changes to the port-specific
initarm() function. Several ports have already been converted and will
be committed shortly.

Use cached physical addresses for mbufs and clusters to save having
to extract the physical address from the virtual.

On the ARM, also use the "read-only at MMU" indication to avoid a
redundant cache clean operation.

Other platforms should use these two as examples of how to use these
new pool/mbuf features to improve network performance.  Note this requires
a platform to provide a working POOL_VTOPHYS().

Part 3 in a series of simple patches contributed by Wasabi Systems
to improve network performance.

Overhaul how DMA ranges work in the ARM bus_dma implementation.

A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length.  In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

Change the way that DMA map syncs are done.  Instead of remembering
the virtual address for each DMA segment, just cache a pointer to the
original buffer/buftype used to load the DMA map, and use that.  This
lets us shrink the bus_dma_segment_t down from 12 bytes to 8, and the
cache flushing is also more efficient.

Tested on an i80321 -- changes to others are mechanical.

Remove complaint: bus_dmamap_destroy() called for map with valid
mappings bus_dma(9) states: "In the event that the DMA handle contains
a valid mapping, the mapping will be unloaded via the same mechanism
used by bus_dmamap_unload()."  And some drivers do mean to skip the
unload step.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

Overhaul bus_dmamap_sync for the ARM:
* Track which process (XXX really, vmspace) owns the mapping.  When
  we sync the map, if the mapping doesn't belong to the kernel or to
  the current process (XXX really, vmspace), then no cache fobbing
  is necessary, since the cache is Wb-Inv'd on context switch (XXX need
  to revisit this when we support FCSE).
* Be smarter about which cache operation we do when sync'ing the map:
  - PREREAD -- Invalidate D$ (XXX right now, we actually do Wb-Inv)
  - PREWRITE -- Write-back D$ (note, we do NOT invalidate here)
  - PREREAD|PREWRITE -- Wb-Inv D$

More work is needed here.  In particular, a version for CPUs
with write-through caches should be provided, to eliminate
the write-back steps (which are noops on such CPUs, but skipping
two branches would be nice).

Overhaul of the ARM cache code.  This is mostly a simplification
pass.  Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:

	icache_sync_all         Synchronize I-cache
	icache_sync_range       Synchronize I-cache range

	dcache_wbinv_all        Write-back and Invalidate D-cache
	dcache_wbinv_range      Write-back and Invalidate D-cache range
	dcache_inv_range        Invalidate D-cache range
	dcache_wb_range         Write-back D-cache range

	idcache_wbinv_all       Write-back and Invalidate D-cache,
				Invalidate I-cache
	idcache_wbinv_range     Write-back and Invalidate D-cache,
				Invalidate I-cache range

Note: This does not yet include an overhaul of the actual asm files
that implement the primitives.  Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.

Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
