ee8ecea34b MFp4: 
- Try hard to calculate a safe sp, so that the stack doesn't get smashed
while uncompressing or relocating the kernel.
- Bring in code needed to calculate the cacheline size etc, needed for
arm9_idcache_wbinv_all.

9464ffd0a4 MFp4: Increase the L1 pagetable needed for the kernel from 8 to 22, to be 
able to boot fat kernels.

fd5cb69756 Remove pmap_pagedaemon_waken and update pmap_get_pv_entry() to match the 
current interface with the machine-independent layer.  Without this change,
the page daemon would only have been awakened the first time that the
number of pv entries went above the high water mark, not each time.

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
