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macppc/if_gm.c (superseded by gem(4))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!)

When running an N32 kernel, run it with 64-bit addresses even though the
kernel itself will only use 32-bit addresses.  There are exceptions.
bus_space_handles are now register_t instead of intptr_t.  This allows them
to contain XKPHYS addresses.  Now bus_space can use XKPHYS addresses and
not required non-KSEG1 devices to be mapped in KSEG2 thereby leaving more
KSEG2 space for the kernel to use.

The cache range routines (but not index routines) now take a register_t
instead of vaddr_t so they can too take a XKPHYS address.  This allows the
pmap to use a page's XKPHYS address to clean sync the icache thereby avoiding
massive icache invalidations.

Since "cache" instruction effects are global to all CPUs and their caches, we
can use the above to greatly simplify MP page isyncs.  If using an O32 kernel
with pages outside KSEG0, index ops still need to be performed since there
isn't an a quick way of mapping the page.

Add an optimization for UP system with non-virtually tagged caches (which are
most of them these days).

If a page needs to be have an icache_sync performed and the page has a direct
map alias (XKPHYS or KSEG0), then don't do an index op; instead do a range op
on the XKPHYS or KSEG0 address.  This results in unneeded fewer cache line
invalidations.

Make uvm_map recognize UVM_FLAG_COLORMATCH which tells uvm_map that the
'align' argument specifies the starting color of the KVA range to be returned.

When calling uvm_km_alloc with UVM_KMF_VAONLY, also specify the starting
color of the kva range returned (UMV_KMF_COLORMATCH) and pass those to
uvm_map.

In uvm_pglistalloc, make sure the pages being returned have sequentially
advancing colors (so they can be mapped in a contiguous address range).
Add a few missing UVM_FLAG_COLORMATCH flags to uvm_pagealloc calls.

Make the socket and pipe loan color-safe.

Make the mips pmap enforce strict page color (color(VA) == color(PA)).

Add support for the Extensible MIPS ("eMIPS") platform.  The
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.

eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing.  eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.

NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman.  Microsoft Corporation has
donated full copyright to The NetBSD Foundation.

Platform support for eMIPS is the first part of Microsoft's
contribution.  The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.

	sys/arch/mips/mips/cache.c: revision 1.30
Partially revert change in sys/arch/mips/mips/cache.c rev 1.27,
i.e. override mips_cache_alias_mask and mips_cache_prefer_mask
with values which match MIPS3_MAX_PCACHE_SIZE (32KB), rather than
leave them actual primary virtual indexed cache size (8KB or 16KB).
Also add comments about what the value means there.
I thought the VCE on R4000/R4400 occurred only if actual virtual alias
was detected because there was an article which mentioned that VCE
detection logic was different according to primary cache size and
it looked reasonable. But all other articles I can find later
(http://www.linux-mips.org/archives/linux-mips/1998-05/msg00084.html etc.)
claimes that VCE detection logic always verifies all 3 bits
between vaddr[14:12] and PIdx[2:0] regardless of primary cache size
(i.e. VCE could occur even if there is no actual virtual alias), and
in fact VCED still happens with the mask values adjusted for 16KB L1
but it doesn't with ones for MIPS3_MAX_PCACHE_SIZE on my R4400 news5000.

Add a workaround to handle virtual alias which may cause data corruption
on R5000/Rm52xx machines:
- Add a new global variable mips_cache_virtual_alias in mips/cache.c,
  which indicates that VIPT cache on the CPU could cause virtual alias
  and software support is required to handle it. (i.e. no VCED/VCEI)
- Add several cache flush/invalidate ops around KSEG0 access which
  might cause virtual alias if mips_cache_virtual_alias is true.
  (note checking mips_sdcache_line_size isn't valid for R5000/Rm52xx
   because only R4000/R4400 with L2 cache have VCED/VCEI)
- Remove a global variable mips_sdcache_forceinv, which is now superseded

Partially revert change in sys/arch/mips/mips/cache.c rev 1.27,
i.e. override mips_cache_alias_mask and mips_cache_prefer_mask
with values which match MIPS3_MAX_PCACHE_SIZE (32KB), rather than
leave them actual primary virtual indexed cache size (8KB or 16KB).
Also add comments about what the value means there.

I thought the VCE on R4000/R4400 occurred only if actual virtual alias
was detected because there was an article which mentioned that VCE
detection logic was different according to primary cache size and
it looked reasonable. But all other articles I can find later
(http://www.linux-mips.org/archives/linux-mips/1998-05/msg00084.html etc.)
claimes that VCE detection logic always verifies all 3 bits
between vaddr[14:12] and PIdx[2:0] regardless of primary cache size
(i.e. VCE could occur even if there is no actual virtual alias), and
in fact VCED still happens with the mask values adjusted for 16KB L1
but it doesn't with ones for MIPS3_MAX_PCACHE_SIZE on my R4400 news5000.

Add a workaround to handle virtual alias which may cause data corruption
on R5000/Rm52xx machines:
- Add a new global variable mips_cache_virtual_alias in mips/cache.c,
  which indicates that VIPT cache on the CPU could cause virtual alias
  and software support is required to handle it. (i.e. no VCED/VCEI)
- Add several cache flush/invalidate ops around KSEG0 access which
  might cause virtual alias if mips_cache_virtual_alias is true.
  (note checking mips_sdcache_line_size isn't valid for R5000/Rm52xx
   because only R4000/R4400 with L2 cache have VCED/VCEI)
- Remove a global variable mips_sdcache_forceinv, which is now superseded
  by new mips_cache_virtual_alias.

While here, also change some R4000/R4400 cache ops:
- Don't override mips_cache_alias_mask and mips_cache_prefer_mask with

Add a hint variable (mips_sdcache_forceinv, explicitly initialized to zero)
that tells pmap_zero_page() and pmap_copy_page() to unconditionally invalidate
pages for r5k-class CPUs with secondary cache.

This behavior must be explicitly enabled by setting mips_sdcache_forceinv to 1.

This is the last bit of a patch that has been kicked around since 2000 between
rafal@, tsutsui@, and myself.

cache_r10k.c rev. 1.1 is broken. Because,

	1) R10k uses VA0 to select cache ways, but in rev. 1.1, VA14
	   is used instead.
	2) R10k does not support HitWriteBack and should map HitWriteBack
	   to HitWriteBackInvalidate, but in rev. 1.1, HitWriteBack is not
	   handled properly.

So, cache_r10k.c rev. 1.1 was replaced by new implementation.

one of the data cache line size variables is changed, in order to
compute mips_dcache_align and mips_dcache_align_mask.
