their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
Probably a bug. I use a temporary variable. I have not tested this
change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
Probably a bug. Use a local pci_attach_args. I have not tested
this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
caller's pci_attach_args. Probably a bug. Make a local copy of the
caller's pci_attach_args and modify the copy. I have not tested
this change.

While I'm here, make pci_mapreg_submap() static.

Adapt to <spr.h> breakup.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.

Instead of mapping whole RAM with reserved TLB entries, map just enough
to ensure trap code will work (that is 0 upto ${endkernel}) and leave the
rest to pmap_tlbmiss(). Mapping whole physmem into the kernel wired way
too many TLB entries, see

http://mail-index.netbsd.org/port-powerpc/2006/10/27/0000.html

for performance analysis. While there, be a bit more descriptive in
pmap_tlbmiss() comment and use macro instead of numeric constant.

OK by Simon Burge

* convert ibm4xx-based evbppc from reserved-TLB entry allocation to recently
introduced ppc4xx_tlb_reserve() API.
* ibm405gp UART0 used to be linear mapped. The VA happens to be inside kernel
segment, giving us the possibility of multiple VA matches in the TLB. This
is considered "programming error" by 405 core and results in "undefined
behaviour". We now avoid mapping peripherals in kernel segment.
* Some boards used to map hardwired RAM size. We now use the real size as
passed in by boot firmware.

Tidy up a little.

Replace the traditional buffer memory management -- based on fixed per buffer
virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.

This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms. Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.

On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.

Do not rely on an address from one particular firmware version.

Nuke ci_curpm and curpm. Nuke pcb_pmreal. Those were use for spill stacks
and those no longer exist. for few uses that need CURPM, use CURPCB/PCB_PM

Walnut evaluation board, which up until now lived in arch/walnut.

arch/walnut will go away soon, once all the remaining walnut-isms
in the tree have been dealt with.

Fix various typos in comments.

Change todr_chip_handle::cookie -> todr_chip_handle::todr_dev, and
make it a device_t. Upcoming functional changes will require the
device_t associated with a TODR device.

Change todr_chip_handle::bus_cookie -> todr_chip_handle::todr_devaux.
Nothing was using the old field, but I decided to keep it around just
in cause something needs it in the future.

And with these largely mechanical yet semantically meaningful changes,
thus spake the Oracle: "Welcome to NetBSD 11.99.2."

use the inline bcdtobin and bintobcd directly instead through a macro.

branches: 1.9.12;
#include <sys/bus.h> instead of <machine/bus.h>.

- convert to use device_t, cfattach_t, CFATTACH_DECL_NEW etc.
- in dsrtcattach() use struct clock_ymdhms instead of rtc in DEBUG code block,
and move that block down after sc_todr.cookie is initialized so dsrtc_read() works.

Merge thorpej-cfargs2.

branches: 1.14.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

branches: 1.13.68;
#include <sys/bus.h> instead of <machine/bus.h>.

in pbus_attach() make locs[] and pass to config_found_sm_loc()
to avoid triggering KASSERT in config_stdsubmatch().

More device_t, cfdata, CFATTACH_DECL_NEW cleanup.

branches: 1.10.88; 1.10.98;
Use config_stdsubmatch() instead of a local submatch function.

convert remaining autoconf bus "submatch" functions to use the new

serve any purpose
(untested, sorry)

Need to rename dsrtc to ds1743rtc here too.
