Current code check boot service region with kernel text region by:
start+size = __pa_symbol(_text)
The end of the above region should be start + size - 1 instead.
I see this problem in ovmf + Fedora 19 grub boot:
text start: 100 md start: 80 md size: 80

We checked pfmemalloc by slab unit, not page unit. You can see this
in is_slab_pfmemalloc(). So other pages don't need to be set/cleared
pfmemalloc.
And, therefore we should check pfmemalloc in page flag of first page,
but current implementation don't do that. virt_to_head_page(obj) just
return
Now, bufctl is not proper name to this array.
So change it.

Now, there are a few field in struct slab, so we can overload these
over struct page. This will save some memory and reduce cache footprint.
After this change, slabp_cache and slab_size no longer related to
a struct slab, so rename them as freelist_cache and freelist_size.
These changes are just
We can get cachep using page in struct slab_rcu, so remove it.

With build-time size checking, we can overload the RCU head over the LRU
of struct page to free pages of a slab in rcu context. This really help to
implement to overload the struct slab over the struct page and this
eventually reduce memory usage and cache footprint of the SLAB.
