I've updated four previous patches (previously against pre7) that try to
comment and document how the VM in 2.4.19pre8 works. I've posted them
before on the list so I'm just going to include URL's this time. They are
2.4.19pre8_documentation_numa
http://www.csn.ul.ie/~mel/projects/vm/patches/2.4.19pre8_documentation_numa
Extends the Documentation/vm/numa file to try and describe NUMA and
related data structures a bit better
2.4.19pre8_page_alloc_commentry
http://www.csn.ul.ie/~mel/projects/vm/patches/2.4.19pre8_page_alloc_commentry
This extends the documentation on page_alloc.c to describe how the buddy
allocator works
2.4.19pre8_slab_commentry
http://www.csn.ul.ie/~mel/projects/vm/patches/2.4.19pre8_slab_commentry
Extends the commentry on the slab allocator slightly
2.4.19pre8_vmalloc_commentry
http://www.csn.ul.ie/~mel/projects/vm/patches/2.4.19pre8_vmalloc_commentry
Documents how vmalloc works
If there is no complaints, I'll see what I can do about getting them
integrated into the main branch. Thanks to all those who provided feedback
with them

One way to describe the bit toggling behavior is saying that each page
has a "virtual bit", the bit present in the bitmap is the xor of the
"virtual bits" of the two buddies, and the buddy's bit is recovered by
xor'ing with the bit of the page we're examining, which is known from
the entry point.
Cheers,
Bill
