Adjust _all_ cinclude of *.local files

- Ensure always at end
- Use tab rather than spaces
- Add consistent comment
"Pull in optional local configuration - always at end"

The only functional change is that a local file which tried to
override an existing setting (eg with "no foo") would have failed
in some cases before, but now will work

Ensure GENERIC.local is always at the end of GENERIC

Where a GENERIC config had an existing inclusion of GENERIC.local,
ensure it is always at the end of the file, with a consistent
comment:

# Pull in optional local configuration
cinclude "arch/landisk/conf/GENERIC.local"

This allows GENERIC.local to correctly override all options

(This pass does not affect any GENERIC which did not already have
an include of GENERIC.local)

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel

- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

Driver for the I2C bus used for RAM serial presence detection. This
I2C interface is implemented by bit-banging a couple of GPIO pins on
the Sequoia core logic used in the Shark.

Heavy lifting by Julian Coleman, and minor tweaks and a different
autoconfiguration scheme by me.

- Introduce sequoiaLock() / sequoiaUnlock() functions that hide away
the details of what's going on (disable / restore interrupts), and
use it consistently.
- Give "sequoia" a device_t in the system device tree, matching on
the Shark's /vlbus/isa node, acting a subclass of ofisa (an "ofisa"
will be attached to "sequoia"). This allows us to attach other logical
device nodes to the "sequoia".

Garbage-collect the old Shark-specific "pccons" stuff. Shark has
been wscons for some time now.

"ofisa" carried an "ofbus" interface attribute in addition to its own
in order to attach an "ofrtc" instance. This worked prior to the
autconfiguration system enforcing non-ambiguous interface attribute
specificaitons due to how the attach args for ofisa were structured.

But it no longer works, and is a big dodgy barring a formalized "subclassing"
facility for interface atributes in config(5).

So, stop using "ofrtc" on Shark, and replace it with an ofisa driver for
the mc146818 real time clock hardware, and remove "ofbus" from "ofisa".

We actually have a big problem: the fileassocs are never deleted.
Therefore, if a user generates a lot of buggy binaries and launches them
all, the kernel will allocate memory again again and again for all these
entries and will never free them (unless the files are deleted from the
disk). Which means that a user can too easily put the kernel under memory
pressure.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART

as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr

UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is

the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Some ARM32_PMAP_NEW-related cleanup:
* Define a new "MMU type", ARM_MMU_SA1. While the SA-1's MMU is basically
compatible with the generic, the SA-1 cache does not have a write-through
mode, and it is useful to know have an indication of this.
* Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at
compile time. We evaluate it like so:
- If SA-1-style MMU is the only type configured -> 1
- If SA-1-style MMU is not configured -> 0
- Otherwise, defer to a run-time variable.
If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time
check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly
code can include the necessary run-time support. PMAP_INCLUDE_PTE_SYNC
largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve
included with the original new pmap.
* In the new pmap, make pmap_pte_init_generic() check to see if the CPU
has a write-back cache. If so, init the PT cache mode to C=1,B=0 to get
write-through mode. Otherwise, init the PT cache mode to C=1,B=1.
* Add a new pmap_pte_init_arm8(). Old pmap, same as generic. New pmap,
sets page table cacheability to 0 (ARM8 has a write-back cache, but
flushing it is quite expensive).
* In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to
C=1,B=0, since the write-back check in generic gets it wrong for ARM9,
since we use write-through mode all the time on ARM9 right now. (What
this really tells me is that the test for write-through cache is less
than perfect, but we can fix that later.)
* Add a new pmap_pte_init_sa1(). Old pmap, same as generic. New pmap,
does generic initialization, then resets page table cache mode to
C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.

Heavy lifting by Julian Coleman, and minor tweaks and a different

- Introduce sequoiaLock() / sequoiaUnlock() functions that hide away
the details of what's going on (disable / restore interrupts), and
use it consistently.
- Give "sequoia" a device_t in the system device tree, matching on
the Shark's /vlbus/isa node, acting a subclass of ofisa (an "ofisa"
will be attached to "sequoia"). This allows us to attach other logical
device nodes to the "sequoia".

Garbage-collect the old Shark-specific "pccons" stuff. Shark has
been wscons for some time now.

"ofisa" carried an "ofbus" interface attribute in addition to its own
in order to attach an "ofrtc" instance. This worked prior to the
autconfiguration system enforcing non-ambiguous interface attribute
specificaitons due to how the attach args for ofisa were structured.

But it no longer works, and is a big dodgy barring a formalized "subclassing"
facility for interface atributes in config(5).

So, stop using "ofrtc" on Shark, and replace it with an ofisa driver for
the mc146818 real time clock hardware, and remove "ofbus" from "ofisa".

We actually have a big problem: the fileassocs are never deleted.
Therefore, if a user generates a lot of buggy binaries and launches them
all, the kernel will allocate memory again again and again for all these
entries and will never free them (unless the files are deleted from the
disk). Which means that a user can too easily put the kernel under memory
pressure.

Remove KMEMSTATS.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

This branch was a major cleanup and rototill of many of the various OEA

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.

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable

Some ARM32_PMAP_NEW-related cleanup:
* Define a new "MMU type", ARM_MMU_SA1. While the SA-1's MMU is basically
compatible with the generic, the SA-1 cache does not have a write-through
mode, and it is useful to know have an indication of this.
* Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at
compile time. We evaluate it like so:
- If SA-1-style MMU is the only type configured -> 1
- If SA-1-style MMU is not configured -> 0
- Otherwise, defer to a run-time variable.
If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time
check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly
code can include the necessary run-time support. PMAP_INCLUDE_PTE_SYNC
largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve
included with the original new pmap.
* In the new pmap, make pmap_pte_init_generic() check to see if the CPU
has a write-back cache. If so, init the PT cache mode to C=1,B=0 to get
write-through mode. Otherwise, init the PT cache mode to C=1,B=1.
* Add a new pmap_pte_init_arm8(). Old pmap, same as generic. New pmap,
sets page table cacheability to 0 (ARM8 has a write-back cache, but
flushing it is quite expensive).
* In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to
C=1,B=0, since the write-back check in generic gets it wrong for ARM9,
since we use write-through mode all the time on ARM9 right now. (What
this really tells me is that the test for write-through cache is less
than perfect, but we can fix that later.)
* Add a new pmap_pte_init_sa1(). Old pmap, same as generic. New pmap,
does generic initialization, then resets page table cache mode to
C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.

Driver for the I2C bus used for RAM serial presence detection. This
I2C interface is implemented by bit-banging a couple of GPIO pins on
the Sequoia core logic used in the Shark.

Heavy lifting by Julian Coleman, and minor tweaks and a different
autoconfiguration scheme by me.

- Introduce sequoiaLock() / sequoiaUnlock() functions that hide away
the details of what's going on (disable / restore interrupts), and
use it consistently.
- Give "sequoia" a device_t in the system device tree, matching on
the Shark's /vlbus/isa node, acting a subclass of ofisa (an "ofisa"
will be attached to "sequoia"). This allows us to attach other logical
device nodes to the "sequoia".

Garbage-collect the old Shark-specific "pccons" stuff. Shark has
been wscons for some time now.

"ofisa" carried an "ofbus" interface attribute in addition to its own
in order to attach an "ofrtc" instance. This worked prior to the
autconfiguration system enforcing non-ambiguous interface attribute
specificaitons due to how the attach args for ofisa were structured.

But it no longer works, and is a big dodgy barring a formalized "subclassing"
facility for interface atributes in config(5).

So, stop using "ofrtc" on Shark, and replace it with an ofisa driver for
the mc146818 real time clock hardware, and remove "ofbus" from "ofisa".

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
clusters.

Remove GENERIC.local from the repository

Make all the kernels that currently include their corresponding GENERIC.local
file use the cinclude directive instead of include. This way config(1) will
not complain if the file cannot be found.

After doing this, remove the GENERIC.local files from the repository so that
the user will not see modified files during updates, and local changes to
them cannot end up in the repository by mistake.

Discussed in tech-kern@ earlier this month. No strong objections.

branches: 1.77.2; 1.77.6;
Support a GENERIC.local file.

Remove arm support for IPKDB.

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.

Move 'options FONT_VT220L8x16' to a common place for all kernels so that

Force vga(4) to override the font built into the VGA ROM by one that

adjust comments for the new location of wskbdmap_mfii.c,
addresses PR kern/33290 by henry nelson

Remove the getwschar and putwschar accessops from wsdisplay drivers as
requested by uwe@. These were wrong because they were receiving an
emulcookie yet they were accessops (thus having to receive an accesscookie).
Instead, just handle the WSDISPLAYIO_{GET,PUT}WSCHAR ioctls from the
driver's ioctl accessop.

As this reduces the amount of code needed to handle these operations to
two small functions in each driver, remove the WSDISPLAY_CHARFUNCS kernel
option.

Reviewed by, at least, uwe@ and macallan@. No objections in tech-kern@.

Add stf to all kernel configs which have INET6 and gif, except the INSTALL

XXX: This option should be mentioned in options(4).

turn off DEBUG and DIAGNOSTIC in GENERIC kernels so that they
are compatible with the LKMs that are part of the release.

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).

Enable ptyfs by default on the non-install and non small/tiny/ramdisk kernels
