Subject[PATCH 3.12 02/88] MIPS: Fix 64k page support for 32 bit kernels.
From: Ralf Baechle <>

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


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.
