7477838f2e ARM: SoC defconfig updates for 3.16
A number of defconfig updates for 3.16. We have quite a few of these as
 new SoCs and drivers get supported, and we've started collecting them
 in one shared branch.
 
 We started halfway through the merge window so there'll be some small
 conflicts with other branches on nearby changes, but nothing major. Next
 cycle should be smoother.

c67d9ce166 ARM: SoC board support updates for 3.16
The bulk of this branch is updates for Renesas Shmobile. They are still
 doing some enablement for classic boards first, and then come up with DT
 bindings when they've had a chance to learn more about the hardware. Not
 necessarily a bad way to go about it, and they're looking at moving some
 of the temporary board code resulting from it to drivers/staging instead
 to avoid the churn here.
 
 As a result of the shmobile clock cleanups, we end up merging quite a
 bit of SH code here as well. We ended up merging it here instead of in
 the cleanup branch due to the other board changes depending on it.

825f4e0271 ARM: SoC updates for 3.16 (part 1)
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

a3530e8fe9 x86/efi: Do not export efi runtime map in case old map
For ioremapped efi memory aka old_map the virt addresses are not persistant
across kexec reboot. kexec-tools will read the runtime maps from sysfs then
pass them to 2nd kernel and assuming kexec efi boot is ok. This will cause
kexec boot failure.

To address this issue do not export runtime maps in case efi old_map so
userspace can use no efi boot instead.

ca8f0b0a54 ARM: ensure C page table setup code follows assembly code
Fix a long standing bug where, for ARMv6+, we don't fully ensure that
the C code sets the same cache policy as the assembly code.  This was
introduced partially by commit 11179d8ca28d ([ARM] 4497/1: Only allow
safe cache configurations on ARMv6 and later) and also by adding SMP
support.

This patch sets the default cache policy based on the flags used by the
assembly code, and then ensures that when a cache policy command line
argument is used, we verify that on ARMv6, it matches the initial setup.

3480593131 net: filter: get rid of BPF_S_* enum
This patch finally allows us to get rid of the BPF_S_* enum.
Currently, the code performs unnecessary encode and decode
workarounds in seccomp and filter migration itself when a filter
is being attached in order to overcome BPF_S_* encoding which
is not used anymore by the new interpreter resp. JIT compilers.

Keeping it around would mean that also in future we would need
to extend and maintain this enum and related encoders/decoders.
We can get rid of all that and save us these operations during
filter attaching. Naturally, also JIT compilers need to be updated
by this.

Before JIT conversion is being done, each compiler checks if A
is being loaded at startup to obtain information if it needs to
emit instructions to clear A first. Since BPF extensions are a
subset of BPF_LD | BPF_{W,H,B} | BPF_ABS variants, case statements
for extensions can be removed at that point. To ease and minimalize
code changes in the classic JITs, we have introduced bpf_anc_helper().

Tested with test_bpf on x86_64 (JIT, int), s390x (JIT, int),
arm (JIT, int), i368 (int), ppc64 (JIT, int); for sparc we
unfortunately didn't have access, but changes are analogous to
the rest.

Joint work with Alexei Starovoitov.

1c8c3cf0b5 ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type
Due to a design incompatibility between the PCIe Marvell controller
and the Cortex-A9, stressing PCIe devices with a lot of traffic
quickly causes a deadlock.

One part of the workaround for this is to have all PCIe regions mapped
as strongly-ordered (MT_UNCACHED) instead of the default
MT_DEVICE. While the arch_ioremap_caller() mechanism allows
sub-architecture code to override ioremap(), used to map PCIe memory
regions, there isn't such a mechanism to override the behavior of
pci_ioremap_io().

This commit adds the arch_pci_ioremap_mem_type variable, initialized
to MT_DEVICE by default, and that sub-architecture code can
override. We have chosen to expose a single variable rather than
offering the possibility of overriding the entire pci_ioremap_io(),
because implementing pci_ioremap_io() requires calling functions
(get_mem_type()) that are private to the arch/arm/mm/ code.

c191920f73 x86/vdso, build: Make LE access macros clearer, host-safe
Make it a little clearer what the littleendian access macros in
vdso2c.[ch] actually do.  This way they can probably also be moved to
a central location (e.g. tools/include) for the benefit of other host
tools.

We should avoid implementation namespace symbols when writing code
that is compiling for the compiler host, so avoid names starting with
double underscore or underscore-capital.

add4eed0a2 x86/vdso, build: Fix cross-compilation from big-endian architectures

little-endian.  Hopefully I put it everywhere it needs to go and got
all the cases needed for everyone's linux/elf.h.

There is very little and maybe practically nothing we can do to recover
from a system where at least one core has reached a timeout during the
whole monarch cores gathering. So panic when that happens.
