Move function prototypes to asm/signal.h to detect trivial errors and
add some __user tags to get rid of sparse warnings.  Generated code
should not be changed.

From 8145095cd8fd466980ea6401f26a52e462275222 Mon Sep 17 00:00:00 2001
From: Ralf Baechle <ralf@linux-mips.org>
Date: Wed, 22 Feb 2006 23:06:55 +0000
Subject: [MIPS] Remove CONFIG_BUILD_ELF64.

This option is no longer usable with supported compilers.  It will be
replaced by usage of -msym32 in a separate patch.

Subject: [MIPS] sys_mmap2 offset argument should always be shifted 12, not
 PAGE_SHIFT.

This patch adjusts the offset argument passed into sys_mmap2 to be
always shifted 12, even when the native page size isn't 4K.  This is
what all existing userspace libraries expect.

Subject: [PATCH] more for_each_cpu() conversions

When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all.  The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().

This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
few instances of this bug, if any.  But the patch converts lots of open-coded
test to use the preferred helper macros.
