4.4-stable review patch. If anyone has any objections, please let me know.

From: Ralf Baechle <ralf@linux-mips.org>
commit d7de413475f443957a0c1d256e405d19b3a2cb22 upstream.
TASK_SIZE was defined as 0x7fff8000UL which for 64k pages is not a multiple of the page size. Somewhere further down the math fails such that executing an ELF binary fails.
