Raising math exception from fpu_save causes machine reboots.
Also, this fwait would cause incorrect results, as pending exceptions

configuration of devices logically attached to the ISA bus:
* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.
is what Solaris8 calls it
implement SVR4_TRAP_GETHRESTIME, though obviously only with microsecond accuracy
now clock_gettime(CLOCK_REALTIME, tp) works on Solaris8/i386
of a range which is protected by spl/splx. Originally proposed by
YAMAMOTO Takashi (yamt@netbsd.org) on tech-kern. This change mirrors
the one done by Bill Sommerfeld on the i386 mp branch.
Notes:
- I added bsd.obj.mk and made it work with objdirs.
- I added an entry point to the linker to fix a warning.
- I made the backup of biostramp.inc silent.
- I added missing clean targets.
This needs to be tested further.
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

These changes will allow platforms like x86 (XMM) and PowerPC
(AltiVec) to export extended register sets in a sane manner.
* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
/proc/N/xmmregs in procfs.
* need to specify DMA channel for DMACMD_SET_IO
* the upper byte of port was masked incorrectly
also update comment in _mca_bus_dmamap_sync() to current reality
* add flag to explicitly specify if the DMA should be done as 16bit or 8bit
* add flag to specify the DMA should happen via I/O port
* add new function mca_dma_set_ioport(), to set I/O port to be used for the
DMA operation

to get the buffer bouncing for >16MB RAM machines. The MCA DMA

Export mca_dmamap_create(), which returns map suitable for further DMA

Use symbolic names for DMA controller commands - I've finally got
info what they mean from Tymm Twillman's Linux include/asm/mca_dma.h.
No more magic constants! Also fix bug in the way DMA counter has been
setup - for 16bit DMA, it's necessary to tell the controller _half_
the byte count. This was wrong in the former code.
Don't make clean and cleandir depend on the lib subdir.
Just check for it's existance before running the submake.
This makes it possible to run a make build (which runs

that anyone installs over HIPPI either. On the other hand, lots of people
would like to be able to install over their wireless networks or with their
Tigon Gig-E cards: so, let's synchronize this file's contents with the
modern world (at least a little bit).
Note that we really need to decide whether, as they used to be, the INSTALL
config files will be GENERIC with some lines *deleted* or whether they will
be GENERIC with some lines commented out. Using both styles is bad, but I
haven't fixed it in this commit.

Thanks to MOCHIDA Shuji for initial investigation on the issue, that helped
to find the bug a lot.
Make sure the CPUCLASS_686 entry has really 17 (i.e. 16 + default)
name entries as it's supposed to, so that code won't crash when
run on Intel CPUCLASS_686 processor which doesn't have name entry
in the table.

XXX Note that the new sigcontext uses the new sigset_t instead of old
int sc_mask. The new FreeBSD sigcontext doesn't contain any backward
compatibility sc_mask, so basically old FreeBSD application making
use of sigcontext are hosed. This can't be fixed in NetBSD compat code.
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.
Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
amount of kvm used for buffers was set at 70%, some 188M. Then
the total amount of kvm became 1G, and the amount for buffers
thus became some 716M. This is really too much, and some
device drivers want to map quite a bit of kvm these days.
So, cap it at 384M, which gives each buffer a little over 8k (the
default FFS blocksize) physical in an 1G physram configuration.
-remove the check for i810's internal graphics completely: we'll attach
AGP whether in GFX or AGP mode anyway, and the SMRAM register test
was of questionable value (should have masked with 0xc0, but even then
the builtin graphics appeared enabled although I used an external
PCI card)
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.
device (rather, the device that carries that attribute) also
carry one or more attributes indicating which type of controller
it might be.
This will allow systems that might have AGP, but would never have
e.g. an Intel PCI-Host bridge, to trim out code that won't be used.
This prevents attaching multiple [E]ISA buses, which we don't support
(Is there any such thing to support? I'm skeptical) and avoids the
"panic: isaattach: ISA bus already seen" that occurs on some laptops
with docking stations and EISA boxes. Since there is only one [E]ISA bus,
logically, the ISA device probe will still find devices on the
docking station.
This does not address the problem of inserting or removing the docking station
at runtime.

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.

This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!
C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart. Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so. It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have. The DES CBC code
doesn't have this problem.
Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.
in the ARMADA config. On the M700 at least, the SMBus host controller lies
it 0x4000 (the beginning of the range allocated by default to rbus), and
stomping all over it causes bad things to happen.
