ce142d9ec0 Introduce the function pmap_enter_object(). It maps a sequence of resident 
pages from the same object.  Use it in vm_map_pmap_enter() to reduce the
locking overhead of premapping objects.

4cd3385ee3 If our buffer is not aligned on the cache line size, write back/invalidate 
the first and last cache line in PREREAD, and just invalidate the cache
lines in POSTREAD, instead of write-back/invalidating in POSTREAD, which
could lead to stale data overriding what has been transfered by DMA.

ec4c4a14f5 Uncomment the call to cpu_idcache_wbinv_all() after the MMU has been 
enabled. It has been commented out for a reason I forgot but I suspect
does not apply anymore.
Technically speaking it's not required to do it, has the data and the
instruction cache have been disabled in _start(). However, it may change
in the future, so I don't want to rely on this behavior.

d5d776c16b Resurrect Skyeye support : 
Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds
workarounds for things skyeye doesn't simulate. Specifically :
- Use USART0 instead of DBGU as the console, make it not use DMA, and           manually provoke an interrupt when we're done in the transmit function.
- Skyeye maintains an internal counter for clock, but apparently there's
no way to access it, so hack the timecounter code to return a value which
is increased at every clock interrupts. This is gross, but I didn't find a
better way to implement timecounters without hacking Skyeye to get the
counter value.
- Force the write-back of PTEs once we're done writing them, even if they
are supposed to be write-through. I don't know why I have to do that.

04091343f6 Move the call to cpu_setup() before the call to vm_ksubmap_init(). 
vm_ksubmap_init() calls pmap_copy_page(), which uses the mini data cache
to do the copy, but we're running uncaching before cpu_setup().
For some reason it hasn't been a problem so far, but it is for the
PXA255.

Retire pmap_track_modified().  We no longer need it because we do not
create managed mappings within the clean submap.  To prevent regressions,
add assertions blocking the creation of managed mappings within the clean
submap.
