Yes, I would say you're right. Trimming the mapping to _end only leaves
the space under the kernel avaliable for allocating pagetable from e820
space. In this case we've got DEBUG_PAGEALLOC enabled, which inhibits
the use of PSE, and BIOS corruption checking on, which eats a chunk of
low memory. In combination, there's only 0x8f000 bytes free below the
kernel, and it needs 0xe1000 to allocate for pagetables.
Reverting 2bd2753ff46346543ab92e80df9d96366e21baa5 fixes the problem for
me, though it does result in a kernel with a 73MB BSS...
