97958cafc8 - Rename ds1672 and ds133x devices to "ds1672_rtc" and "ds133x_rtc"
respectivly. This will allow one to have a kernel with both devices
  present and use it for multiple boards with different types of RTC
  sitting on a bus.

9725389e1e Don't conditionally define CACHE_LINE_SHIFT, as we anticipate sizing
a fair number of static data structures, making this an unlikely
option to try to change without also changing source code. [1]

Change default cache line size on ia64, sparc64, and sun4v to 128
bytes, as this was what rtld-elf was already using on those
platforms. [2]

a93fa8f2bb For each architecture, define CACHE_LINE_SHIFT and a derived
CACHE_LINE_SIZE constant.  These constants are intended to
over-estimate the cache line size, and be used at compile-time
when a run-time tuning alternative isn't appropriate or
available.

Defaults for all architectures are 64 bytes, except powerpc
where it is 128 bytes (used on G5 systems).

cd899aad76 Fix KBI breakage by r190520 which affects older linux.ko binaries:
1) Move the new field (brand_note) to the end of the Brandinfo structure.
2) Add a new flag BI_BRAND_NOTE that indicates that the brand_note pointer
   is valid.
3) Use the brand_note field if the flag BI_BRAND_NOTE is set and as old
   modules won't have the flag set, so the new field brand_note would be
   ignored.

beb3c3a9c5 Retire VM_PROT_READ_IS_EXEC. It was intended to be a micro-optimization,
but I see no benefit from it today.

VM_PROT_READ_IS_EXEC was only intended for use on processors that do not
distinguish between read and execute permission.  On an mmap(2) or
mprotect(2), it automatically added execute permission if the caller
specified permissions included read permission.  The hope was that this
would reduce the number of vm map entries needed to implement an address
space because there would be fewer neighboring vm map entries that differed
only in the presence or absence of VM_PROT_EXECUTE.  (See vm/vm_mmap.c
revision 1.56.)

Today, I don't see any real applications that benefit from
VM_PROT_READ_IS_EXEC.  In any case, vm map entries are now organized
as a self-adjusting binary search tree instead of an ordered list.  So,
the need for coalescing vm map entries is not as great as it once was.

339ccfb391 Hoist 802.11 encapsulation up into net80211:
o call ieee80211_encap in ieee80211_start so frames passed down to drivers
  are already encapsulated
o remove ieee80211_encap calls in drivers
o fixup wi so it recreates the 802.3 head it requires from the 802.11
  header contents
o move fast-frame aggregation from ath to net80211 (conditional on
  IEEE80211_SUPPORT_SUPERG):
  - aggregation is now done in ieee80211_start; it is enabled when the
    packets/sec exceeds ieee80211_ffppsmin (net.wlan.ffppsmin) and frames
    are held on a staging queue according to ieee80211_ffagemax
    (net.wlan.ffagemax) to wait for a frame to combine with
  - drivers must call back to age/flush the staging queue (ath does this
    on tx done, at swba, and on rx according to the state of the tx queues
    and/or the contents of the staging queue)
  - remove fast-frame-related data structures from ath
  - add ieee80211_ff_node_init and ieee80211_ff_node_cleanup to handle
    per-node fast-frames state (we reuse 11n tx ampdu state)
o change ieee80211_encap calling convention to include an explicit vap
  so frames coming through a WDS vap are recognized w/o setting M_WDS

With these changes any device able to tx/rx 3Kbyte+ frames can use fast-frames.

o encode need for A4 bus space tag hackery according to the memory

o encode the correct memory window instead of carving up all of i/o
  space, potentially with a larger window than a device should have;
  this likely should be handled in the drivers by using a proper bus
  alloc call but since some drivers depend on the bus support to figure
  this out we cannot simply mod them

  isn't ready yet)

74aed9855d Add support for the FPA floating-point format on ARM. The
FPA floating-point format is identical to the VFP format,
but is always stored in big-endian.
Introduce _IEEE_WORD_ORDER to describe the byte-order of
the FP representation.

67bda09e9b Merge support for Gateworks Cambria boards:
o add support for IXP435 cpu's (e.g. 64 irq's)
o add support for Cambria-specific devices: npe, led's (front panel and
  octal latch), ehci, mcu, ide cf
o redo memory mapping for xscale/ixp4xx boards: previously memory
  was assumed aliased to 0x10000000 but this appears to be true only
  for ixp425 systems and breaks operation on others; rework so memory
  is assumed to start at 0
o rework NPE configuration support to use NPE id's instead of port #'s;
  these changes also rename the associated MAC's to follow the NPE's
  they are attached to
o update npe firmware to latest rev (same license) and update default fw
  imageid's to match; in particular this adds NPE-A and crypto support
o re-style NPE fw handling code and add a console msg identifying the
  attributes of the loaded fw
o fix numerous problems with handling failures during npe setup
o fix npe rx q setup; need to spin waiting for mailbox responses during
  early boot stages as qmgr interrupts are not delivered; this fixes
  the problem where all 8 traffic classifications were not tied to the
  rx q (and eliminates the console msg "remember to fix rx q setup")
o add DELAY to npe MII wait logic for IXP435
o strip down builtin phys->virt address translation table in resource
  handling to just those resources that require it and add a console msg
  to alert people when this (kludge) table needs to be extended
o purge a bunch of dead netbsd-ism's
o cleanup avila led driver
o add Cambria support to boot2 and rework code for better multi-board support

Notes:
  1. NPE-A doesn't work and causes NPE-C to stop working; it is disabled
     in the hints
  2. USB isn't working yet; controller communicates ok but device
     discovery fails
  3. Cambria support must be configured separately from IXP425 boards;
     multi-board support is TBD

5289eda203 Do not use cached page for temporary mapping in pmap_zero_page_generic()
The physical page which we clear is accessed via additional temp kernel
mapping for the period of zeroing operation. However in systems with virtual
d-cache (most ARMs) when write-allocate feature is enabled, we can have
modified but unflushed content pertaining to this physical page still in the
d-cache due to its primary (pre-existing) mapping. In such scenario that
cached content upon flush is likely to overwrite [portions of] the physical
page we want to zero here..

This is a general problem with multiple virtual mappings covering the same
physical page with write-allocate and virtual d-cache: there is inherent
potential for corruptions of this kind, which are not easily resolved; it is
best policy that such multiple mappings be not allowed.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

virtualization work done by Marko Zec (zec@).

This is the first in a series of commits over the course

Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.

We hope to have caught at least 85-90% of what is needed

13e3657b7b Add locking to the various iicbus(4) bridge drivers:
- Just grab Giant in the ixp425_iic(4) driver since this driver uses
  a shared address/data register window pair to access the actual
  I2C registers.  None of the other ixp425 drivers lock access to these
  shared address/data registers yet and that would need to be done before
  this could use any meaningful locking.
- Add locking to the interrupt handler and 'iicbus_reset' methods of the
  at91_twi(4) driver.
- Add locking to the pcf(4) driver.  Other pcf(4) fixes include:
  - Don't needlessly zero the softc.
  - Use bus_foo rather than bus_space_foo and remove bus space tag and
    handle from softc.
- The lpbb(4) driver just grabs Giant for now.  This will be refined later
  when ppbus(4) is locked.
- As was done with smbus earlier, move the DRIVER_MODULE() lines to match
  the bus driver (either iicbus or iicbb) to the bridge driver into the
  bridge drivers.

As clearly mentioned on the mailing lists, there is a list of drivers
that have not been ported to the MPSAFE TTY layer yet. Remove them from
the kernel configuration files. This means people can now still use
these drivers if they explicitly put them in their kernel configuration
file, which is good.

People should keep in mind that after August 10, these drivers will not
work anymore. Even though owners of the hardware are capable of getting
these drivers working again, I will see if I can at least get them to a

43d7128c14 Expand kdb_alt_break a little, most commonly used with the option
ALT_BREAK_TO_DEBUGGER.  In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).

We've used variations of this at work.  The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.

The reboot request is a safer way of getting into single user than
a power cycle.  eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.

I've taken my best guess at what the !x86 and non-sio code changes
should be.

This also makes sio release its spinlock before calling KDB/DDB.

9b4a8ab7ba Now that all platforms use genclock, shuffle things around slightly
for better structure.

Much of this is related to <sys/clock.h>, which should really have
been called <sys/calendar.h>, but unless and until we need the name,
the repocopy can wait.

In general the kernel does not know about minutes, hours, days,
timezones, daylight savings time, leap-years and such.  All that
is theoretically a matter for userland only.

Parts of kernel code does however care: badly designed filesystems
store timestamps in local time and RTC chips almost universally
track time in a YY-MM-DD HH:MM:SS format, and sometimes in local
timezone instead of UTC.  For this we have <sys/clock.h>

<sys/time.h> on the other hand, deals with time_t, timeval, timespec
and so on.  These know only seconds and fractions thereof.

Move inittodr() and resettodr() prototypes to <sys/time.h>.
Retain the names as it is one of the few surviving PDP/VAX references.

Move startrtclock() to <machine/clock.h> on relevant platforms, it
is a MD call between machdep.c/clock.c.  Remove references to it
elsewhere.

Remove a lot of unnecessary <sys/clock.h> includes.

Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs.
XXX: should be kern.disable_rtc_set really, it's not MD.

- Rename the intr_event 'eoi', 'disable', and 'enable' hooks to
  'post_filter', 'pre_ithread', and 'post_ithread' to be less x86-centric.
  Also, add a comment describe what the MI code expects them to do.
- On amd64, i386, and powerpc this is effectively a NOP.
- On arm, don't bother masking the interrupt unless the ithread is
  scheduled in the non-INTR_FILTER case to match what INTR_FILTER did.
  Also, don't bother unmasking the interrupt in the post_filter case if
  we never masked it.  The INTR_FILTER case had been doing this by having
  arm_unmask_irq for the post_filter (formerly 'eoi') hook.
- On ia64, stray interrupts are now masked for the non-INTR_FILTER case.
  They were already masked in the INTR_FILTER case.
- On sparc64, use the a NULL pre_ithread hook and use intr_enable_eoi() for
  both the 'post_filter' and 'post_ithread' hooks to match what the
  non-INTR_FILTER code did.
- On sun4v, retire the ithread wrapper hack by using an appropriate
  'post_ithread' hook instead (it's what 'post_ithread'/'enable' was

eaf86d1678 Add preliminary support for binding interrupts to CPUs:
- Add a new intr_event method ie_assign_cpu() that is invoked when the MI
  code wishes to bind an interrupt source to an individual CPU.  The MD
  code may reject the binding with an error.  If an assign_cpu function
  is not provided, then the kernel assumes the platform does not support
  binding interrupts to CPUs and fails all requests to do so.
- Bind ithreads to CPUs on their next execution loop once an interrupt
  event is bound to a CPU.  Only shared ithreads are bound.  We currently
  leave private ithreads for drivers using filters + ithreads in the
  INTR_FILTER case unbound.
- A new intr_event_bind() routine is used to bind an interrupt event to
  a CPU.
- Implement binding on amd64 and i386 by way of the existing pic_assign_cpu
  PIC method.
- For x86, provide a 'intr_bind(IRQ, cpu)' wrapper routine that looks up
  an interrupt source and binds its interrupt event to the specified CPU.
  MI code can currently (ab)use this by doing:

	intr_bind(rman_get_start(irq_res), cpu);

  however, I plan to add a truly MI interface (probably a bus_bind_intr(9))

6617724c5f Remove kernel support for M:N threading.
While the KSE project was quite successful in bringing threading to
FreeBSD, the M:N approach taken by the kse library was never developed
to its full potential.  Backwards compatibility will be provided via
libmap.conf for dynamically linked binaries and static binaries will
be broken.

e081d0ac19 Improve ARM_TP_ADDRESS and RAS area.
De-hardcode usage of ARM_TP_ADDRESS and RAS local storage, and move this
special purpose page to a more convenient place i.e. after the vectors high
page, more towards the end of address space. Previous location (0xe000_0000)
caused grief if KVA was to go beyond the default limit.

Note that ARM world rebuilding is required after this change since the
location of ARM_TP_ADDRESS is shared between kernel and userland.

8f2948f1c1 Bring in the nice work from Mark Tinguely on arm pmap.
The only downside is that it renames pmap_vac_me_harder() to pmap_fix_cache().
From Mark's email on -arm :
pmap_get_vac_flags(), pmap_vac_me_harder(), pmap_vac_me_kpmap(), and
pmap_vac_me_user() has been rewritten as pmap_fix_cache() to be more
efficient in the kernel map case. I also removed the reference to
the md.kro_mappings, md.krw_mappings, md.uro_mappings, and md.urw_mappings
counts.

In pmap_clearbit(), we can also skip over tests and writeback/invalidations
in the PVF_MOD and PVF_REF cases if those bits are not set in the pv_flag.
PVF_WRITE will turn caching back on and remove the PV_MOD bit.

In pmap_nuke_pv(), the vm_page_flag_clear(pg, PG_WRITEABLE) has been moved
to the pmap_fix_cache().

We can be more agressive in attempting to turn caching back on by calling
pmap_fix_cache() at times that may be appropriate to turn cache on
(a kernel mapping has been removed, a write has been removed or a read
has been removed and we know the mapping does not have multiple write
mappings to a page).

In pmap_remove_pages() the cpu_idcache_wbinv_all() is moved to happen
before the page tables are NULLed because the caches are virtually
indexed and virtually tagged.

In pmap_remove_all(), the pmap_remove_write(m) is added before the
page tables are NULLed because the caches are virtually indexed and
virtually tagged. This also removes the need for the caches fixing routine
(whichever is being used pmap_vac_me_harder() or pmap_fix_cache()) to be
called on any of these mappings.

In pmap_remove(), I simplified the cache cleaning process and removed
extra TLB removals. Basically if more than PMAP_REMOVE_CLEAN_LIST_SIZE
are removed, then just flush the entire cache.
