In order to test the preload code, it is necessary to fail GFP_ATOMIC allocations, which requires defining GFP_KERNEL and GFP_ATOMIC properly. Remove the obsolete __GFP_WAIT and copy the definitions of the __GFP flags which are used from the kernel include files. We also need the real definition of gfpflags_allow_blocking() to persuade the radix tree to actually use its preallocated nodes.
