This is kind of similar to the ARM bug fixed in 98ed805c3.
I wonder if we ought to have a per-CPU #define for "largest
possible page alignment for this architecture" as well as
"smallest possible" (the latter being TARGET_PAGE_MASK).

This patch is a reasonable enough way to fix things though,
so I'm not objecting to it.

Aside: given the repetitive nature of the context hunks
observable in this patch, it looks like it ought to be
possible to abstract out some of the initrd/kernel load
code from all those boards...
