2eeafe13a6 Introduce a new function, pmap_wb_page(), which check all userland mappings for 
a given page and, if the pmap is the current pmap, write back the associated
cache line.
Use pmap_wb_page in pmap_qenter() instead of inconditionally
write back/invalidating the data cache.

5974e5c71c Refactor the bus_dma header files so that the interface is described in 
sys/bus_dma.h instead of being copied in every single arch.  This slightly
reorders a flag that was specific to AXP and thus changes the ABI there.
The interface still relies on bus_space definitions found in <machine/bus.h>
so it cannot be included on its own yet, but that will be fixed at a later
date.  Add an MD <machine/bus_dma.h> for ever arch for consistency and to
allow for future MD augmentation of the API.  sparc64 makes heavy use of
this right now due to its different bus_dma implemenation.

da53588551 Make sure ARM_TP_ADDRESS is accessible right now by calling pmap_fault_fixup,

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central 
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

f4c01f1508 Instead of using sysarch() to store-retrieve the tp, add a magic address, 
ARM_TP_ADDRESS, where the tp will be stored. On CPUs that support it, a cache
line will be allocated and locked for this address, so that it will never go
to RAM. On CPUs that does not, a page is allocated for it (it will be a bit
slower, and is wrong for SMP, but should be fine for UP).
The tp is still stored in the mdthread struct, and at each context switch,
ARM_TP_ADDRESS gets updated.

e1e6b9d3c6 - The IQ80321 has a jumper which changes the PCI device id from 4 to 8 for the 
GigE controller, so handle this.
- Use the outbound window 0 if the PCI mem requested is in its range, instead
of inconditionally use the outbound window 1.
This should be enough to get FreeBSD/arm to work on the IQ80321 board as well.

85f5b24573 In the common case, pmap_enter_quick() completes without sleeping. 
In such cases, the busying of the page and the unlocking of the
containing object by vm_map_pmap_enter() and vm_fault_prefault() is
unnecessary overhead.  To eliminate this overhead, this change
modifies pmap_enter_quick() so that it expects the object to be locked
on entry and it assumes the responsibility for busying the page and
unlocking the object if it must sleep.  Note: alpha, amd64, i386 and
ia64 are the only implementations optimized by this change; arm,
powerpc, and sparc64 still conservatively busy the page and unlock the
object within every pmap_enter_quick() call.

Additionally, this change is the first case where we synchronize
access to the page's PG_BUSY flag and busy field using the containing
object's lock rather than the global page queues lock.  (Modifications
to the page's PG_BUSY flag and busy field have asserted both locks for
several weeks, enabling an incremental transition.)

90f794aaaf If we're still running at the physical address, jump to the virtual address 
instead before calling initarm().
This removes the need to map virtual == physical in initarm().

d39d4a6e64 - Change the ddb paging "support" to use a variable (db_lines_per_page) to 
control the number of lines per page rather than a constant.  The variable
  can be examined and changed in ddb as '$lines'.  Setting the variable to
  0 will effectively turn off paging.
- Change db_putchar() to force out pending whitespace before outputting
  newlines and carriage returns so that one can rub out content on the
  current line via '\r     \r' type strings.
- Change the simple pager to rub out the --More-- prompt explicitly when
  the routine exits.
- Add some aliases to the simple pager to make it more compatible with
  more(1): 'e' and 'j' do a single line.  'd' does half a page, and
  'f' does a full page.

6052fa47a9 Import partial support for the IQ31244 eval board (i80321 CPU). IQ80321 might 
work out of the box too, but I have no hardware to test.
It works well enough to go multiuser. Network works, SATA does not, as I have
no drive to test.
Thanks to Intel for sending such a board.
