x86/vm86: Fix the misleading CONFIG_VM86 Kconfig help text
The CONFIG_VM86 Kconfig help text is actively misleading, so fix it:
- Don't mark it 'obsolete' in the text as we'll support the ABI as long as CPUs
support it.
- Qualify the part about software emulation and mention that for some apps you
want a real vm86 mode.
- Don't scare users away from the option, instead explain what it does.

x86/vm86: Block non-root vm86(old) if mmap_min_addr != 0
vm86 exposes an interesting attack surface against the entry code. Since vm86 is mostly useless anyway if mmap_min_addr != 0, just turn it off in that case. There are some reports that vbetool can work despite setting mmap_min_addr to zero. This shouldn't break that use case, as CAP_SYS_RAWIO already overrides mmap_min_addr.

x86/alternatives: Make optimize_nops() interrupt safe and synced
Richard reported the following crash:
[ 0.036000] BUG: unable to handle kernel paging request at 55501e06
[ 0.036000] IP: [<c0aae48b>] common_interrupt+0xb/0x38

[ 0.036000] [<c040a054>] apply_alternatives+0x274/0x630
Chuck decoded:

Interrupt 0x30 occurred while the alternatives code was replacing the
initial 0x90,0x90,0x90 NOPs (from the ASM_CLAC macro) with the
optimized version, 0x8d,0x76,0x00. Only the first byte has been
replaced so far, and it makes a mess out of the insn decoding."
optimize_nops() is buggy in two aspects:
- It's not disabling interrupts across the modification
- It's lacking a sync_core() call
Add both.

x86/mm/srat: Print non-volatile flag in SRAT
With the addition of NVDIMM support, a question came up as to whether NVDIMM ranges should be in the SRAT with this bit set. I think the consensus was no because the ranges are in the NFIT with proximity domain information there. ACPI is not clear on the meaning of this bit in the SRAT. If someone is setting it, we might want to ask them what they expect to happen with it. Right now this bit is only printed if all the ACPI debug information is turned on.

ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
tends to gather drivers that need SoC modification or dependencies such
that they have to (also) go in through our tree.
For this release, we have merged in part of the reset controller tree
(with handshake that the parts we have merged in will remain stable),
as well as dependencies on a few clock branches.
In general, new items here are:
- Qualcomm driver for SMM/SMD, which is how they communicate with the
coprocessors on (some) of their platforms
- Memory controller work for ARM's PL172 memory controller
- Reset drivers for various platforms
- PMU power domain support for Marvell platforms
- Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

Pull ARM SoC driver updates from Olof Johansson:
"Some releases this branch is nearly empty, others we have more stuff.
It tends to gather drivers that need SoC modification or dependencies
such that they have to (also) go in through our tree.
For this release, we have merged in part of the reset controller tree
(with handshake that the parts we have merged in will remain stable),
as well as dependencies on a few clock branches.
In general, new items here are:
- Qualcomm driver for SMM/SMD, which is how they communicate with the
coprocessors on (some) of their platforms
- memory controller work for ARM's PL172 memory controller
- reset drivers for various platforms
- PMU power domain support for Marvell platforms
- Tegra support for T132/T210 SoCs: PMC, fuse, memory controller
per-SoC support"

ARM: SoC cleanups for v4.3
A large cleanup branch this release, with a healthy 10k negative line delta.
Most of this is removal of legacy (non-DT) support of shmobile
platforms. There is also removal of two non-DT platforms on OMAP,
and the plat-samsung directory is cleaned out by moving most of the
previously shared-location-but-not-actually-shared files from there to
the appropriate mach directories instead.
There are other sets of changes in here as well:
- Rob Herring removed use of set_irq_flags under all platforms and
moved to genirq alternatives
- A series of timer API conversions to set-state interface
- ep93xx, nomadik and ux500 cleanups from Linus Walleij
- __init annotation fixes from Nicolas Pitre
+ a bunch of other changes that all add up to a nice set of cleanups

Pull NOHZ updates from Ingo Molnar:
"The main changes, mostly written by Frederic Weisbecker, include:
- Fix some jiffies based cputime assumptions. (No real harm because
the concerned code isn't used by full dynticks.)
- Simplify jiffies <-> usecs conversions. Remove dead code.
- Remove early hacks on nohz full code that avoided messing up idle
nohz internals. Now nohz integrates well full and idle and such
hack have become needless.
- Restart nohz full tick from irq exit. (A simplification and a
preparation for future optimization on scheduler kick to nohz
full)
- Code cleanups.
- Tile driver isolation enhancement on top of nohz. (Chris Metcalf)"

- Add support for using several Intel PT features (CYC, MTC packets),
the relevant documentation was updated in:
tools/perf/Documentation/intel-pt.txt
briefly describing those packets, its purposes, how to configure
them in the event config terms and relevant external documentation
for further reading. (Adrian Hunter)
- Introduce support for probing at an absolute address, for user and
kernel 'perf probe's, useful when one have the symbol maps on a
developer machine but not on an embedded system. (Wang Nan)
- Add Intel BTS support, with a call-graph script to show it and PT
in use in a GUI using 'perf script' python scripting with
postgresql and Qt. (Adrian Hunter)
- Allow selecting the type of callchains per event, including
disabling callchains in all but one entry in an event list, to save
space, and also to ask for the callchains collected in one event to
be used in other events. (Kan Liang)
- Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
de Melo)
* A bunch more translate file/pathnames from pointers to strings.
* Convert numbers to strings for the 'keyctl' syscall 'option'
arg.
* Add missing 'clockid' entries.
- Introduce 'srcfile' sort key: (Andi Kleen)
# perf record -F 10000 usleep 1
# perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
<SNIP>
# Overhead Source File
26.49% copy_page_64.S
5.49% signal.c
0.51% msr.h
#
It can be combined with other fields, for instance, experiment with
'-s srcfile,symbol'.
There are some oddities in some distros and with some specific
DSOs, being investigated, so your mileage may vary.
- Support per-event 'freq' term: (Namhyung Kim)
$ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
$ perf evlist -F
cpu/instructions,freq=1234/: sample_freq=1234
cycles: sample_period=1000
$
- Deref sys_enter pointer args with contents from probe:vfs_getname,
showing pathnames instead of pointers in many syscalls in 'perf
trace'. (Arnaldo Carvalho de Melo)
- Stop collecting /proc/kallsyms in perf.data files, saving about
4.5MB on a typical x86-64 system, use the the symbol resolution
routines used in all the other tools (report, top, etc) now that we
can ask libtraceevent to use perf's symbol resolution code.
(Arnaldo Carvalho de Melo)
- Allow filtering out of perf's PID via 'perf record --exclude-perf'.
(Wang Nan)
- 'perf trace' now supports syscall groups, like strace, i.e:
$ trace -e file touch file
Will expand 'file' into multiple, file related, syscalls. More
work needed to add extra groups for other syscall groups, and also
to complement what was added for the 'file' group, included as a
proof of concept. (Arnaldo Carvalho de Melo)
- Add lock_pi stresser to 'perf bench futex', to test the kernel code
related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso)
- Let user have timestamps with per-thread recording in 'perf record'
(Adrian Hunter)
- ... and tons of other changes, see the shortlog and the Git log for
details"

regulator: Updates for v4.3
The biggest changes in the core this time around have been some
refactorings that move us towards being able to drop the list of
regulators maintained by the core and instead just use the driver model
list maintained for the class devices for regulators which will make the
code smaller and avoid some potential bugs. Otherwise another fairly
quiet release for the regulator API, highlights include:
- A new API for setting voltages based on a minimum, target, maximum
triplet.
- Support for continuous voltage ranges rather than tables of explicit
steps in the PWM regulator, requiring less explicit configuration.
- New driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
and Qualcomm RPM.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky: "The big one is support for fake NUMA, splitting a really large machine in more manageable piece improves performance in some cases, e.g. for a KVM host. The FICON Link Incident handling has been improved, this helps the operator to identify degraded or non-operational FICON connections. The save and restore of floating point and vector registers has been overhauled to allow the future use of vector registers in the kernel. A few small enhancement, magic sys-requests for the vt220 console via SCLP, some more assembler code has been converted to C, the PCI error handling is improved. And the usual cleanup and bug fixing" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (59 commits) s390/jump_label: Use %*ph to print small buffers s390/sclp_vt220: support magic sysrequests s390/ctrlchar: improve handling of magic sysrequests s390/numa: remove superfluous ARCH_WANT defines s390/3270: redraw screen on unsolicited device end s390/dcssblk: correct out of bounds array indexes s390/mm: simplify page table alloc/free code s390/pci: move debug messages to debugfs s390/nmi: initialize control register 0 earlier s390/zcrypt: use msleep() instead of mdelay() s390/hmcdrv: fix interrupt registration s390/setup: fix novx parameter s390/uaccess: remove uaccess_primary kernel parameter s390: remove unneeded sizeof(void *) comparisons s390/facilities: remove transactional-execution bits s390/numa: re-add DIE sched_domain_topology_level s390/dasd: enhance CUIR scope detection s390/dasd: fix failing path verification s390/vdso: emit a GNU hash s390/numa: make core to node mapping data dynamic ... |

USB patches for 4.3-rc1
Here's the big USB and PHY patchset for 4.3-rc1. As usual, the majority of the changes are in the USB gadget portion of the tree, lots of little changes all over the place for bugs and new hardware. Other than that, the normal mix of new hardware support and bugfixes. All have been in linux-next with no reported issues.
