Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed.  Default cortex to pmap_needs_fixup = 1.  But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.

Use cpu_* prefix to call cpu_* functions (setttb() -> cpu_setttb()); no
functional changes.

Garbage collect an unused global, vm_offset_t pagetables_start.

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Kill proc0paddr.  Use lwp0.l_addr instead.

Remove all declarations of physmem from sys/arch.  Add an include of
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)

Allow IQ80321-derived systems to provide an m.d. reboot routine.
Use this on the IQ31244 to force a watchdog reset from the M41ST84
if it's been attached.  The generic reset doesn't fully reset the
system whereas the RTC watchdog reset does.

Update haad-dm branch to haad-dm-base2.

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.

__KERNEL_RCSID()

Use the new pmap_devmap facility in the on-board device mapping code.

Replace the ad-hoc "section mapping table" for static device mappings
with a more generic "devmap" structure that can also handle mappings
made with large and small pages.  Add new pmap routines to enter these
mappings during bootstrap (and "remember" the devmap), and routines to
look up the static mappings once the kernel is running.

Also pass a type argument to comcnattach() and com_kgdb_attach().
comspeed() (and thus cominit()) may need this information.

Move KERNEL_VM_SIZE into the C files where its used.

Move KERNEL_VM_BASE inside where it is used (it won't be there for long).

Decrease the verbosity level unless VERBOSE_INIT_ARM is defiend.

Don't expose KERNEL_TEXT_BASE outside of board-specific code.  This gives
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

Reduce differences between ARM32_NEW_VM_LAYOUT and not; always pass
the start and end of the kernel managed virtual address space to
pmap_bootstrap() in the new pmap.

Remove old pmap support for platforms which have fully switched over.

Eliminate PTE_BASE and the PT-PT completely in the ARM32_PMAP_NEW case.
Also in the ARM32_PMAP_NEW case, reclaim the USPACE-bytes of wasted space
at the top of the user address that hasn't been needed for a very very
long time.

Bump kernel PTs to 4 (the max we can really have with the old VM
layout) to accomodate large ramdisks.  Set boothowto if BOOTHOWTO
is defined.

Attach com to kgdb if both KGDB and com are defined.

Call ksyms_init() instead of ddb_init() in case of
	NKSYMS || defined(DDB) || defined(LKM)

Use high vectors on IQ80321 and IQ80310.

Don't use ARM32_NEW_VM_LAYOUT or initarm_common() for now. It's not
quite ready for prime-time on evbarm.

Add support for ARM32_PMAP_NEW and ARM32_NEW_VM_LAYOUT to the iq80321 port.

Use PAGE_SIZE rather than NBPG.

Revert pull-up of revision 1.10 (requested by rearnsha in ticket #1170):
  Revert cached memory access to L1 tables, this causes instability
  on the release branch.

  Do cached memory access to L1 tables, making sure to
  write-back the cache after any L1 table modifications.

Enable caching on kernel and user page tables.  This saves having
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

Do cached memory access to L1 tables, making sure to write-back the
cache after any L1 table modifications.

Partial (ARM only) sync with trunk -- significant performance improvements
for XScale-based systems.

Compile properly without DIAGNOSTIC defined.

Move the calls to uvm_page_physload() out of pmap_bootstrap() and
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical.  Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

Move the uvm_setpagesize() call to platform-dependent code in preparation
for other changes to pmap_bootstrap().

* Add the ability to display .'s on the 7seg display.
* Display . . when halted.

* Move the code that cleans the XScale mini-data cache into its
  own function.
* Add a new function which sets up the mini-data cache clean area
  properly.

* Rewrite the 32-bit ARM pte.h based on the ARM architecture manual.
  Significant cleanup, here, including better PTE bit names.
* Add XScale PTE extensions (ECC enable, write-allocate cache mode).
* Mechanical changes everywhere else to update for new pte.h.  While
  doing this, two bugs (as a result of typos) were fixed in

	arm/arm32/bus_dma.c
	evbarm/integrator/int_bus_dma.c

Clean up handling of the vector page on 32-bit ARM systems:
* Don't refer to VA 0, instead refer to a new variable: vector_page
* Delete the old zero_page_*() functions, replacing them with a new
  one: vector_page_setprot().
* When manipulating vector page mappings in user pmaps, only do so if
  the vector page is below KERNEL_BASE (if it's above KERNEL_BASE, the
  vector page is mapped by the kernel pmap).
* Add a new function, arm32_vector_init(), which takes the virtual
  address of the vector page (which MUST be valid when the function
  is called) and a bitmask of vectors the kernel is going to take
  over, and performs all vector page initialization, including setting
  the V bit in the CPU Control register ("relocate vectors to high
  address"), if necessary.

Fix resetting the board at reboot.

Support for the Intel IQ80321 eval board for the i80321 I/O Processor.
