- Adding prefaulting of fs0 to avoid page fault deadlocks.
- Fixed a bug that a vmo page_cache equivalence would simply drop a link to
an original vmo, even if the vmo could have more pages outside the page cache,
or if the vmo was not a shadow vmo.
- Fixed a bug with page allocator where recursion would corrupt global variables.
- Now going to fix or re-write a simpler page allocator that works.
When allocating a new area, the alignment calculation of new area
structure was wrong. Hopefully this is now fixed. The original function
with bad alignment was preserved.
When freeing a new area and merging it with adjacent areas, pointer
to previous area was mistakenly used instead of pointer to next.
modified: tasks/libmem/kmalloc/kmalloc.c
Previously python hex() would put an extra 'L' after printing out the
value and this would be trimmed in readelf.py. Now it doesn't seem to
do that so the lsd of the number was trimmed. This patch fixes that.
