Date: Wed, 22 Jun 2016 15:41:22 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Ralf Baechle <ralf@...ux-mips.org>, Joshua Henderson <joshua.henderson@...rochip.com>, James Hogan <james.hogan@...tec.com> Subject: [PATCH 4.4 60/75] MIPS: Fix 64k page support for 32 bit kernels. 4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ralf Baechle <ralf@...ux-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.
