Subject: MIPS: Fix 64k page support for 32 bit kernels.

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.
