Two files that get included when building the multi_v7_defconfig target
fail to build when selecting THUMB2_KERNEL for this configuration.
In both cases, we can just build the file as ARM code, as none of its
symbols are exported to modules, so there are no interworking concerns.
In the iwmmxt.S case, add ENDPROC() declarations so the symbols are
annotated as functions, resulting in the linker to emit the appropriate
mode switches.

If the kernel is running in hypervisor mode or monitor mode we'll
print UK6_32 or UK10_32 if we call into __show_regs(). Let's
update these strings to indicate the new modes that didn't exist
when this code was written.

L1_CACHE_BYTES could be larger than real L1 cache line size.
In that case, flush_pfn_alias() would omit to flush last bytes
as much as L1_CACHE_BYTES - real cache line size.
So fix end address to "to + PAGE_SIZE - 1". The bottom bits of the address
is LINELEN. that is ignored by mcrr.

Modern ARMv7-A/R cores optionally implement below new
hardware feature:
- PXN:
Privileged execute-never(PXN) is a security feature. PXN bit
determines whether the processor can execute software from
the region. This is effective solution against ret2usr attack.
On an implementation that does not include the LPAE, PXN is
optionally supported.
This patch set PXN bit on user page table for preventing
user code execution with privilege mode.

If somebody causes an unexpected bad IRQ, this even will be unnoticed in
both dmesg and system logs. If the "bad" IRQ is stuck, the device will
just hang silently w/o reporting anything. Compare this to the generic
behaviour (from include/asm-generic/hardirq.h) which prints a message
with critical level. So to help everybody, include the same message into
ARM-specific ack_bad_irq().

Use gpio-charger driver instead of pda-power: it automatically cares
about used gpio and since collie does not differentiate between usb and
ac chargers, pda-power is an overkill for it.
As a bonus this allows us to remove gpio_to_irq calls from machine init
call - it is fragile. These gpio_to_irq calls will fail if gpios are
registered later, via device driver mechanisms.

The subarchitecture field in the fpsid register is 7 bits wide on
ARM CPUs using the CPUID identification scheme, spanning bits 22
to 16. The topmost bit is used to designate that the
subarchitecture designer is not ARM when it is set to 1. On
non-CPUID scheme CPUs the subarchitecture field is only 4 bits
wide and the higher bits are used to indicate no double precision
support (bit 20) and the FTSMX/FLDMX format (bits 21-22).
The VFP support code only looks at bits 19-16 to determine the
VFP version. On Qualcomm's processors (Krait and Scorpion) we
should see that we have HWCAP_VFPv3 but we don't because bit 22
is set to 1 to indicate that the subarchitecture is not
implemented by ARM and the rest of the bits are left as 0 because
this is the first subarchitecture that Qualcomm has designed.
Unfortunately we can't just widen the FPSID subarchitecture
bitmask to consider all the bits on a CPUID scheme because there
may be CPUs without the CPUID scheme that have VFP without double
precision support and then the version would be a very wrong and
large number. Instead, update the version detection logic to
consider if the CPU is using the CPUID scheme.
If the CPU is using CPUID scheme, use the MVFR registers to
determine what version of VFP is supported. We already do this
for VFPv4, so do something similar for VFPv3 and look for single
or double precision support in MVFR0. Otherwise fall back to
using FPSID to detect VFP support on non-CPUID scheme CPUs. We
know that VFPv3 is only present in CPUs that have support for the
CPUID scheme so this should be equivalent.

Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...
For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.
The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

Pull more perf updates from Ingo Molnar:
"A second (and last) round of late coming fixes and changes, almost all
of them in perf tooling:
User visible tooling changes:
- Add period data column and make it default in 'perf script' (Jiri
Olsa)
- Add a visual cue for toggle zeroing of samples in 'perf top'
(Taeung Song)
- Improve callchains when using libunwind (Namhyung Kim)
Tooling fixes and infrastructure changes:
- Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
- Fix off-by-one bugs in map->end handling (Stephane Eranian)
- Fix off-by-one bug in maps__find(), also related to map->end
handling (Namhyung Kim)
- Make struct symbol->end be the first addr after the symbol range,
to make it match the convention used for struct map->end. (Arnaldo
Carvalho de Melo)
- Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
live' (Jiri Olsa)
- Fix python test build by moving callchain_param to an object linked
into the python binding (Jiri Olsa)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- Do not include a struct hists per perf_evsel, untangling the
histogram code from perf_evsel, to pave the way for exporting a
minimalistic tools/lib/api/perf/ library usable by tools/perf and
initially by the rasd daemon being developed by Borislav Petkov,
Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo)
- Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
thread maps mean syswide monitoring, reducing the boilerplate for
tools that only want system wide mode. (Arnaldo Carvalho de Melo)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)
and other misc fixes"

Pull sparc fixes from David Miller:
"Here we have two bug fixes:
1) The current thread's fault_code is not setup properly upon entry to
do_sparc64_fault() in some paths, leading to spurious SIGBUS.
2) Don't use a zero length array at the end of thread_info on sparc64,
otherwise end_of_stack() isn't right"
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Do not define thread fpregs save area as zero-length array.
sparc64: Fix corrupted thread fault code.

Pull networking fixes from David Miller:
"A quick batch of bug fixes:
1) Fix build with IPV6 disabled, from Eric Dumazet.
2) Several more cases of caching SKB data pointers across calls to
pskb_may_pull(), thus referencing potentially free'd memory. From
Li RongQing.
3) DSA phy code tests operation presence improperly, instead of going:
if (x->ops->foo)
r = x->ops->foo(args);
it was going:
if (x->ops->foo(args))
r = x->ops->foo(args);
Fix from Andew Lunn"

Net: DSA: Fix checking for get_phy_flags function
