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

fix various typos in word `interrupt', mainly in comments.

Fix workaround for SH-3 PCMCIA bug in accordance with description
found in TECH I vol. 14 (CQ Publishing, Tokyo, 2002, in Japanese),
as well as experiment on real hardware:

Byte-access to area 6 becomes word-access (both CE1# and CE2# are
wrongly asserted), if preceding access is word-wise. Inserting a
dummy byte-access works around the problem. Area 5 is not affected.

Therefore,

(1) Insert a dummy byte-read before all byte-wise operations.

(2) Restrict the workaround to area 6 (channel 0), and rename
fixup_sh3_pcmcia_area() to fixup_sh3_pcmcia_area6() for clarity.

Also, we used to use 0xba000000 (== HD64461_PCC0_IOBASE) as target
for the dummy read. However, this can modify device states, which
breaks ep(4) at least. Thus,

(3) Use HD64461_PCC0_MEMBASE as target for the dummy read. This is
assigned to attribute memory space, and byte-read should be
harmless.

enable to power off and reset card.

cosmetic changes. (whitespace,<tab>)

When we attach a channel, set a high level to DRV control pin of the
external buffer for the PC card connected to the channel. This hack
makes pcmcia cards "being used" at the boot time (by WinCE or NetBSD)
correctly detected. A machine running with root on NFS can now be
properly rebooted.

Add option HD64461PCMCIA_REORDER_ATTACH that attaches channels in
reversed order.

When you boot with two CF cards inserted, this options makes the one
in the "memory only" slot (channel 1), which is almost always the card
with the NetBSD install, attached as wd0.

Unlike using fixed unit numbers in the kernel config, if you boot with
only a single CF card, that single card will still be wd0 regardless
of which slot it is inserted in.

http://mail-index.netbsd.org/port-hpcsh/2003/10/23/0000.html provides
a more verbose description of why this option is convenient for most
usage patterns.

In hd64461pcmcia_chip_io_map set *windowp to 0.

This driver ignores i/o window handle, but most 'at pcmcia'
attachments init their sc_io_window to -1 and then check at detach
time if it was changed from the "bad" value. Keep them happy, so that
they can correctly clean up when card is detached.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation

Simplify and make extensible the config_search() / config_found() /

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

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

Merge thorpej-cfargs2.

branches: 1.34.8;
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?).

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),

- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed

Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
