Tejun Heo 196779b9b4 dump_stack: consolidate dump_stack() implementations and unify their behaviors
Both dump_stack() and show_stack() are currently implemented by each
architecture.  show_stack(NULL, NULL) dumps the backtrace for the
current task as does dump_stack().  On some archs, dump_stack() prints
extra information - pid, utsname and so on - in addition to the
backtrace while the two are identical on other archs.

The usages in arch-independent code of the two functions indicate
show_stack(NULL, NULL) should print out bare backtrace while
dump_stack() is used for debugging purposes when something went wrong,
so it does make sense to print additional information on the task which
triggered dump_stack().

There's no reason to require archs to implement two separate but mostly
identical functions.  It leads to unnecessary subtle information.

This patch expands the dummy fallback dump_stack() implementation in
lib/dump_stack.c such that it prints out debug information (taken from
x86) and invokes show_stack(NULL, NULL) and drops arch-specific
dump_stack() implementations in all archs except blackfin.  Blackfin's
dump_stack() does something wonky that I don't understand.

Debug information can be printed separately by calling
dump_stack_print_info() so that arch-specific dump_stack()
implementation can still emit the same debug information.  This is used
in blackfin.

This patch brings the following behavior changes.

* On some archs, an extra level in backtrace for show_stack() could be
  printed.  This is because the top frame was determined in
  dump_stack() on those archs while generic dump_stack() can't do that
  reliably.  It can be compensated by inlining dump_stack() but not
  sure whether that'd be necessary.

* Most archs didn't use to print debug info on dump_stack().  They do
  now.

An example WARN dump follows.

v2: CPU number added to the generic debug info as requested by s390
    folks and dropped the s390 specific dump_stack().  This loses %ksp
    from the debug message which the maintainers think isn't important
    enough to keep the s390-specific dump_stack() implementation.

    dump_stack_print_info() is moved to kernel/printk.c from
    lib/dump_stack.c.  Because linkage is per objecct file,
    dump_stack_print_info() living in the same lib file as generic
    dump_stack() means that archs which implement custom dump_stack()
    - at this point, only blackfin - can't use dump_stack_print_info()
    as that will bring in the generic version of dump_stack() too.  v1
    The v1 patch broke build on blackfin due to this issue.  The build
    breakage was reported by Fengguang Wu.

Gerald Schaefer 106c992a5e mm/hugetlb: add more arch-defined huge_pte functions
Commit abf09bed3c ("s390/mm: implement software dirty bits")
introduced another difference in the pte layout vs.  the pmd layout on
s390, thoroughly breaking the s390 support for hugetlbfs.  This requires
replacing some more pte_xxx functions in mm/hugetlbfs.c with a
huge_pte_xxx version.

This patch introduces those huge_pte_xxx functions and their generic
implementation in asm-generic/hugetlb.h, which will now be included on
all architectures supporting hugetlbfs apart from s390.  This change
will be a no-op for those architectures.

Al Viro d9dda78bad procfs: new helper - PDE_DATA(inode)
The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

Viresh Kumar b43a7ffbf3 cpufreq: Notify all policy->cpus in cpufreq_notify_transition()
policy->cpus contains all online cpus that have single shared clock line. And
their frequencies are always updated together.

Many SMP system's cpufreq drivers take care of this in individual drivers but
the best place for this code is in cpufreq core.

This patch modifies cpufreq_notify_transition() to notify frequency change for
all cpus in policy->cpus and hence updates all users of this API.

Sasha Levin b67bfe0d42 hlist: drop the node parameter from iterators
I'm not sure why, but the hlist for each entry iterators were conceived

        list_for_each_entry(pos, head, member)

The hlist ones were greedy and wanted an extra parameter:

        hlist_for_each_entry(tpos, pos, head, member)

Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.

Besides the semantic patch, there was some manual work required:

 - Fix up the actual hlist iterators in linux/list.h
 - Fix up the declaration of other iterators based on the hlist ones.
 - A very small amount of places were using the 'node' parameter, this
 was modified to use 'obj->member' instead.
 - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
 properly, so those had to be fixed up manually.

The semantic patch which is mostly the work of Peter Senna Tschudin is here:

Wen Congyang 24d335ca36 memory-hotplug: introduce new arch_remove_memory() for removing page table
For removing memory, we need to remove page tables.  But it depends on
architecture.  So the patch introduce arch_remove_memory() for removing
page table.  Now it only calls __remove_pages().

Note: __remove_pages() for some archtecuture is not implemented
      (I don't know how to implement it for s390).

Linus Torvalds 7ae1c76ee5 arm-soc: pin muxing for sh-mobile
This is another cleanup series, containing the move of the Renesas
 SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
 generic pinctrl subsystem, changing it over to the common interfaces in
 the process.
 
 Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
 we're merging this large branch of pinctrl conversion through arm-soc,
 even though it contains the corresponding conversions for arch/sh. Main
 reason for this is tight dependencies (that will now mostly be broken)
 between the arch/sh and mach-shmobile implementations.
 
 There will be more of this in 3.10 to do device-tree bindings, but this
 is the initial conversion.

Here is the big driver core merge for 3.9-rc1
 
 There are two major series here, both of which touch lots of drivers all
 over the kernel, and will cause you some merge conflicts:
   - add a new function called devm_ioremap_resource() to properly be
     able to check return values.
   - remove CONFIG_EXPERIMENTAL
 
 If you need me to provide a merged tree to handle these resolutions,

Linus Torvalds 460dc1eecf Sound updates for 3.9-rc1
The biggest change in this update is the unification of HD-audio codec
 parsers.  Now the HD-audio codec is parsed in a generic parser code
 which is invoked by each HD-audio codec driver.  Some background
 information is found in David Henningsson's blog entry:
   http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/
 
 Other than that, some random updates/fixes like USB-audio and a bunch
 of small AoC updates as usual.
 
 Highlights:
 
 - Unification of HD-audio parser code (aka generic parser)
 
 - Support of new Intel HD-audio controller, new IDT codecs
 
 - Fixes for HD-audio HDMI audio hotplug
 
 - Haswell HDMI audio fixup
 
 - Support of Creative CA0132 DSP code
 
 - A few fixes of HDSP driver
 
 - USB-audio fix for Roland A-PRO, M-Audio FT C600
 
 - Support PM for aloop driver (and fixes Oops)
 
 - Compress API updates for gapless playback support
 
 For ASoC part:
 
 - Support for a wider range of hardware in the compressed stream code
 
 - The ability to mute capture streams as well as playback streams while
   inactive
 
 - DT support for AK4642, FSI, Samsung I2S and WM8962
 
 - AC'97 support for Tegra
 
 - New driver for max98090, replacing the stub which was there
 
 - A new driver from Dialog
 
 Note that due to dependencies, DTification of DMA support for Samsung
 platforms (used only by the and I2S driver and SPI) is merged here as
 well.

Olof Johansson 7e5fc77931 Merge branch 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/sh-pinmux
From Simon Horman. Based on agreement between me, Paul Mundt, Linus
Walleij and Simon, we're mergning this large branch of pinctrl conversion
through arm-soc, even though it contains the corresponding conversions
for arch/sh. Main reason for this is tight dependencies (that will now
mostly be broken) between the arch/sh and mach-shmobile implementations.

There will be more of this in 3.10 to do device-tree bindings, but this is
the initial conversion.

All boards use sh_pfc_register() directly, remove the unused
sh_pfc_register_info() function.

Kuninori Morimoto a4a2992c53 ASoC: simple-card: add asoc_simple_dai for initializing
Current simple-card driver calls asoc_simple_card_dai_init()
if platform had a asoc_simple_card_dai_init pointer.
And, this initialization function works only
when platform has an applicable initial value for each dai settings.
And basically, almost all sound card requires certain initialization.
This means that almost all platform has initialization settings,
and driver do nothing if it doesn't have settings.

And additionally, current simple-card supports sysclk settings but it was
only for codec.  In order to abolish deviation between cpu and codec,
and in order to simplify processing,
this patch adds asoc_simple_dai, and removed pointless
struct asoc_simple_dai_init_info which was trigger of
calling asoc_simple_card_dai_init().

Greg Kroah-Hartman b881bc469b ARCH: drivers remove __dev* attributes.
This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

(ASoC: fsi: add SND_SOC_DAIFMT_INV_xxx support)
added clock inversion support via snd_soc_dai_set_fmt().
Thus, this patch removed SH_FSI_xxx_INV and fsi_get_info()
from fsi driver, and modified platform settings to use new style.
Then, it cleaned up meaningless settings from platform.

Linus Torvalds 787314c35f IOMMU Updates for Linux v3.8
A few new features this merge-window. The most important one is
 probably, that dma-debug now warns if a dma-handle is not checked with
 dma_mapping_error by the device driver. This requires minor changes to
 some architectures which make use of dma-debug. Most of these changes
 have the respective Acks by the Arch-Maintainers.
 Besides that there are updates to the AMD IOMMU driver for refactor the
 IOMMU-Groups support and to make sure it does not trigger a hardware
 erratum.
 The OMAP changes (for which I pulled in a branch from Tony Lindgren's
 tree) have a conflict in linux-next with the arm-soc tree. The conflict
 is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
 the arm-soc tree. It is safe to delete the file too so solve the
 conflict. Similar changes are done in the arm-soc tree in the common
 clock framework migration. A missing hunk from the patch in the IOMMU
 tree will be submitted as a seperate patch when the merge-window is
 closed.

Merge tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma

Pull Automatic NUMA Balancing bare-bones from Mel Gorman:
 "There are three implementations for NUMA balancing, this tree
  (balancenuma), numacore which has been developed in tip/master and
  autonuma which is in aa.git.

  In almost all respects balancenuma is the dumbest of the three because
  its main impact is on the VM side with no attempt to be smart about
  scheduling.  In the interest of getting the ball rolling, it would be
  desirable to see this much merged for 3.8 with the view to building
  scheduler smarts on top and adapting the VM where required for 3.9.

  The most recent set of comparisons available from different people are

    mel:    https://lkml.org/lkml/2012/12/9/108
    mingo:  https://lkml.org/lkml/2012/12/7/331
    tglx:   https://lkml.org/lkml/2012/12/10/437
    srikar: https://lkml.org/lkml/2012/12/10/397

  The results are a mixed bag.  In my own tests, balancenuma does
  reasonably well.  It's dumb as rocks and does not regress against
  mainline.  On the other hand, Ingo's tests shows that balancenuma is
  incapable of converging for this workloads driven by perf which is bad
  but is potentially explained by the lack of scheduler smarts.  Thomas'
  results show balancenuma improves on mainline but falls far short of
  numacore or autonuma.  Srikar's results indicate we all suffer on a
  large machine with imbalanced node sizes.

  My own testing showed that recent numacore results have improved
  dramatically, particularly in the last week but not universally.
  We've butted heads heavily on system CPU usage and high levels of
  migration even when it shows that overall performance is better.
  There are also cases where it regresses.  Of interest is that for
  specjbb in some configurations it will regress for lower numbers of
  warehouses and show gains for higher numbers which is not reported by
  the tool by default and sometimes missed in treports.  Recently I
  reported for numacore that the JVM was crashing with
  NullPointerExceptions but currently it's unclear what the source of
  this problem is.  Initially I thought it was in how numacore batch
  handles PTEs but I'm no longer think this is the case.  It's possible
  numacore is just able to trigger it due to higher rates of migration.

  These reports were quite late in the cycle so I/we would like to start
  with this tree as it contains much of the code we can agree on and has
  not changed significantly over the last 2-3 weeks."

 "All architectures are converted to new model.  Quite a bit of that

  A lot of ugliness and black magic is gone (-3KLoC total in this one):

   - kernel_thread()/kernel_execve()/sys_execve() redesign.

     We don't do syscalls from kernel anymore for either kernel_thread()
     or kernel_execve():

     kernel_thread() is essentially clone(2) with callback run before we
     return to userland, the callbacks either never return or do
     successful do_execve() before returning.

     kernel_execve() is a wrapper for do_execve() - it doesn't need to
     do transition to user mode anymore.

     As a result kernel_thread() and kernel_execve() are
     arch-independent now - they live in kernel/fork.c and fs/exec.c
     resp.  sys_execve() is also in fs/exec.c and it's completely
     architecture-independent.

   - daemonize() is gone, along with its parts in fs/*.c

   - struct pt_regs * is no longer passed to do_fork/copy_process/
     copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.

   - sys_fork()/sys_vfork()/sys_clone() unified; some architectures
     still need wrappers (ones with callee-saved registers not saved in
     pt_regs on syscall entry), but the main part of those suckers is in
     kernel/fork.c now."

Linus Torvalds 090f8ccba3 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
 "Lots of activity:

   211 files changed, 8328 insertions(+), 4116 deletions(-)

  most of it on the tooling side.

  Main changes:

   * ftrace enhancements and fixes from Steve Rostedt.

   * uprobes fixes, cleanups and preparation for the ARM port from Oleg
     Nesterov.

   * UAPI fixes, from David Howels - prepares the arch/x86 UAPI
     transition

   * Separate perf tests into multiple objects, one per test, from Jiri
     Olsa.

   * Make hardware event translations available in sysfs, from Jiri
     Olsa.

   * Fixes to /proc/pid/maps parsing, preparatory to supporting data
     maps, from Namhyung Kim

   * Implement ui_progress for GTK, from Namhyung Kim

   * Add framework for automated perf_event_attr tests, where tools with
     different command line options will be run from a 'perf test', via
     python glue, and the perf syscall will be intercepted to verify
     that the perf_event_attr fields set by the tool are those expected,
     from Jiri Olsa

   * Add a 'link' method for hists, so that we can have the leader with
     buckets for all the entries in all the hists.  This new method is
     now used in the default 'diff' output, making the sum of the
     'baseline' column be 100%, eliminating blind spots.

   * libtraceevent fixes for compiler warnings trying to make perf it
     build on some distros, like fedora 14, 32-bit, some of the warnings
     really pointed to real bugs.

   * Add a browser for 'perf script' and make it available from the
     report and annotate browsers.  It does filtering to find the
     scripts that handle events found in the perf.data file used.  From
     Feng Tang

   * perf inject changes to allow showing where a task sleeps, from
     Andrew Vagin.

   * Makefile improvements from Namhyung Kim.

   * Add --pre and --post command hooks in 'stat', from Peter Zijlstra.

   * Don't stop synthesizing threads when one vanishes, this is for the
     existing threads when we start a tool like trace.

   * Use sched:sched_stat_runtime to provide a thread summary, this
     produces the same output as the 'trace summary' subcommand of
     tglx's original "trace" tool.

   * Support interrupted syscalls in 'trace'

   * Add an event duration column and filter in 'trace'.

   * There are references to the man pages in some tools, so try to
     build Documentation when installing, warning the user if that is
     not possible, from Borislav Petkov.

   * Give user better message if precise is not supported, from David
     Ahern.

   * Try to find cross-built objdump path by using the session
     environment information in the perf.data file header, from Irina
     Tirdea, original patch and idea by Namhyung Kim.

   * Diplays more output on features check for make V=1, so that one can
     figure out what is happening by looking at gcc output, etc.  From
     Jiri Olsa.

   * Add on_exit implementation for systems without one, e.g.  Android,
     from Bernhard Rosenkraenzer.

   * Only process events for vcpus of interest, helps handling large
     number of events, from David Ahern.

   * Cross compilation fixes for Android, from Irina Tirdea.

   * Add documentation on compiling for Android, from Irina Tirdea.

   * perf diff improvements from Jiri Olsa.

   * Target (task/user/cpu/syswide) handling improvements, from Namhyung
     Kim.

   * Add support in 'trace' for tracing workload given by command line,
     from Namhyung Kim.

   * ... and much more."

Linus Torvalds 414a6750e5 USB patches for 3.8-rc1
Here's the big set of USB patches for 3.8-rc1.
 
 Lots of USB host driver cleanups in here, and a bit of a reorg of the
 EHCI driver to make it easier for the different EHCI platform drivers to
 all work together nicer, which was a reduction in overall code.  We also
 deleted some unused firmware files, and got rid of the very old
 file_storage usb gadget driver that had been broken for a long time.
 This means we ended up removing way more code than added, always a nice
 thing to see:

Linus Torvalds cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.

Peter Zijlstra cbee9f88ec mm: numa: Add fault driven placement and migration
NOTE: This patch is based on "sched, numa, mm: Add fault driven
	placement and migration policy" but as it throws away all the policy
	to just leave a basic foundation I had to drop the signed-offs-by.

This patch creates a bare-bones method for setting PTEs pte_numa in the
context of the scheduler that when faulted later will be faulted onto the
node the CPU is running on.  In itself this does nothing useful but any
placement policy will fundamentally depend on receiving hints on placement
from fault context and doing something intelligent about it.

David Sharp 8cbd9cc625 tracing,x86: Add a TSC trace_clock
In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.

Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

v2:
Move arch-specific bits out of generic code.
v3:
Rename "x86-tsc", cleanups
v7:
Generic arch bits in Kbuild.

renesas_usbhs implements ->pullup() method, switches over
 to devm_request_irq(), adds support for DMA Engine and
 got a few miscelaneous cleanups.
 
 The NCM gadget got an endianness fix and the Ethernet
 gadget a frame size fix.
 
 We're finally removing the g_file_storage gadget and
 sticking to g_mass_storage and the new tcm_usb_gadget
 gadgets since that was a huge duplicaton of effort anyway.
 
 While removing g_file_storage, we also had to fix a bunch
 of defconfigs which were still pointing to the old gadget.
 
 There's a big series getting us closer to being able to
 introduce our configfs interface. The series converts
 functions into loadable modules which will, eventually,
 be registered to the configfs interface.
 
 Other than that there's the usual typo fixes and miscelaneous
 cleanups all over the place.

arch/sh/include/uapi/asm/hw_breakpoint.h was emitted by the UAPI disintegration
script as an empty file because the parent file had no UAPI stuff in it,
despite being marked with "header-y".

Unfortunately, the patch program deletes resultant empty files when applying a
kernel patch.

So just stick a comment in there as a placeholder.

Jeff Layton 91a27b2a75 vfs: define struct filename and have getname() return it
getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.

For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.

This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.

Later, we'll add other information to the struct as it becomes
convenient.
