matt 7ce6450eac Add a merged <pcb.h> for arm26/arm32. 2001-09-03 19:20:27 +00:00
chris 191de4d242 Checking a whole host of pmap changes: 
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap  (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.

Also implemented a page zeroing function when the processor is idling.  Note that hpcarm may wish to disable this.

I believe this code to be stable, if anyone has any problems please shout up.

matt 24a2b394aa Make <sysarch.h> valid for all arm platforms. Adjust/remove port-specific 
includes as required.

bjh21 3622d4e282 Add <arm/endian.h> and remove the cats, dnard and netwinder versions, since 
they're all the same (a redirect to <sys/endian.h>).
 2001-06-23 12:20:27 +00:00
bjh21 80c5d7ab99 Move <arm/arm32/bus.h> to <arm/bus.h>, since it looks like it's going to be 
necessary on arm26 as well.

matt c2214aaf3c Remove includes that only include <arm/*.h>. These are now picked up 
automatically when making kernels. (to be submitted).  Next rev will
eliminate those includes that include <arm/arm32/*.h>

before declaring functions.
