[PATCH] Make page allocator aware of requests for zeroed memory
Thisintroduces __GFP_ZERO as an additional gfp_mask element to allow to
request zeroed pages from the page allocator:
- Modifies the page allocator so that it zeroes memory if __GFP_ZERO is
set
- Replace all page zeroing after allocating pages by prior allocations with
allocations using __GFP_ZERO
