Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.

ARM: rwsem: use asm-generic rwsem implementation2016-09-13T11:23:08+00:00Will Deaconwill.deacon@arm.com2014-02-17T14:13:28+00:00urn:sha1:57be265a1b3034673e481d00e27b72c93b073d13
asm-generic offers an atomic-add based rwsem implementation, which
can avoid the need for heavier, spinlock-based synchronisation on the
fast path.
This patch makes use of the optimised implementation for ARM CPUs.

FROMLIST: arm: mm: support ARCH_MMAP_RND_BITS.2016-09-10T14:51:12+00:00dcashmandcashman@google.com2015-12-29T23:07:17+00:00urn:sha1:53d1ed7798ca6200040c0052121efbafe1874594
(cherry picked from commit https://lkml.org/lkml/2015/12/21/341)
arm: arch_mmap_rnd() uses a hard-code value of 8 to generate the
random offset for the mmap base address. This value represents a
compromise between increased ASLR effectiveness and avoiding
address-space fragmentation. Replace it with a Kconfig option, which
is sensibly bounded, so that platform developers may choose where to
place this compromise. Keep 8 as the minimum acceptable value.
