Takashi Iwai 7639a06c23 ALSA: hda - Move a part of hda_codec stuff into hdac_device
Now some codes and functionalities of hda_codec struct are moved to
hdac_device struct.  A few basic attributes like the codec address,
vendor ID number, FG numbers, etc are moved to hdac_device, and they
are accessed like codec->core.addr.  The basic verb exec functions are
moved, too.

Takashi Iwai d068ebc25e ALSA: hda - Move some codes up to hdac_bus struct
A few basic codes for communicating over HD-audio bus are moved to
struct hdac_bus now.  It has only command and get_response ops in
addition to the unsolicited event handling.

Note that the codec-side tracing support is disabled temporarily
during this transition due to the code shuffling.  It will be
re-enabled later once when all pieces are settled down.

Takashi Iwai e3d280fc6d ALSA: hda - Make snd_hda_bus_type public
Define the common hd-audio driver and device types to bind over
snd_hda_bus_type publicly.  This allows to implement other type of
device and driver code over hd-audio bus.

Now both struct hda_codec and struct hda_codec_driver inherit these
new struct hdac_device and struct hdac_driver, respectively.

The bus registration is done in subsys_initcall() to assure it
before any other driver registrations.

Christophe Vu-Brugier 9bc6548f37 target: do not reject FUA CDBs when write cache is enabled but emulate_write_cache is 0
A check that rejects a CDB with FUA bit set if no write cache is
emulated was added by the following commit:

  fde9f50 target: Add sanity checks for DPO/FUA bit usage

The condition is as follows:

  if (!dev->dev_attrib.emulate_fua_write ||
      !dev->dev_attrib.emulate_write_cache)

However, this check is wrong if the backend device supports WCE but
"emulate_write_cache" is disabled.

This patch uses se_dev_check_wce() (previously named
spc_check_dev_wce) to invoke transport->get_write_cache() if the
device has a write cache or check the "emulate_write_cache" attribute
otherwise.

Petr Mladek 8cb2c2dc47 livepatch: Fix subtle race with coming and going modules
There is a notifier that handles live patches for coming and going modules.
It takes klp_mutex lock to avoid races with coming and going patches but
it does not keep the lock all the time. Therefore the following races are
possible:

  1. The notifier is called sometime in STATE_MODULE_COMING. The module
     is visible by find_module() in this state all the time. It means that
     new patch can be registered and enabled even before the notifier is
     called. It might create wrong order of stacked patches, see below
     for an example.

   2. New patch could still see the module in the GOING state even after
      the notifier has been called. It will try to initialize the related
      object structures but the module could disappear at any time. There
      will stay mess in the structures. It might even cause an invalid
      memory access.

This patch solves the problem by adding a boolean variable into struct module.
The value is true after the coming and before the going handler is called.
New patches need to be applied when the value is true and they need to ignore
the module when the value is false.

Note that we need to know state of all modules on the system. The races are
related to new patches. Therefore we do not know what modules will get
patched.

Also note that we could not simply ignore going modules. The code from the
module could be called even in the GOING state until mod->exit() finishes.
If we start supporting patches with semantic changes between function
calls, we need to apply new patches to any still usable code.
See below for an example.

Finally note that the patch solves only the situation when a new patch is
registered. There are no such problems when the patch is being removed.
It does not matter who disable the patch first, whether the normal
disable_patch() or the module notifier. There is nothing to do
once the patch is disabled.

Alternative solutions:
======================

+ reject new patches when a patched module is coming or going; this is ugly

+ wait with adding new patch until the module leaves the COMING and GOING
  states; this might be dangerous and complicated; we would need to release
  kgr_lock in the middle of the patch registration to avoid a deadlock
  with the coming and going handlers; also we might need a waitqueue for
  each module which seems to be even bigger overhead than the boolean

+ stop modules from entering COMING and GOING states; wait until modules
  leave these states when they are already there; looks complicated; we would
  need to ignore the module that asked to stop the others to avoid a deadlock;
  also it is unclear what to do when two modules asked to stop others and
  both are in COMING state (situation when two new patches are applied)

+ always register/enable new patches and fix up the potential mess (registered
  patches order) in klp_module_init(); this is nasty and prone to regressions
  in the future development

+ add another MODULE_STATE where the kallsyms are visible but the module is not
  used yet; this looks too complex; the module states are checked on "many"
  locations

Example of patch stacking breakage:
===================================

The notifier could _not_ _simply_ ignore already initialized module objects.
For example, let's have three patches (P1, P2, P3) for functions a() and b()
where a() is from vmcore and b() is from a module M. Something like:

	a()	b()
P1	a1()	b1()
P2	a2()	b2()
P3	a3()	b3(3)

If you load the module M after all patches are registered and enabled.
The ftrace ops for function a() and b() has listed the functions in this
order:

	ops_a->func_stack -> list(a3,a2,a1)
	ops_b->func_stack -> list(b3,b2,b1)

, so the pointer to b3() is the first and will be used.

Then you might have the following scenario. Let's start with state when patches
P1 and P2 are registered and enabled but the module M is not loaded. Then ftrace
ops for b() does not exist. Then we get into the following race:

CPU0					CPU1

load_module(M)

  complete_formation()

  mod->state = MODULE_STATE_COMING;
  mutex_unlock(&module_mutex);

					klp_register_patch(P3);
					klp_enable_patch(P3);

					# STATE 1

  klp_module_notify(M)
    klp_module_notify_coming(P1);
    klp_module_notify_coming(P2);
    klp_module_notify_coming(P3);

					# STATE 2

The ftrace ops for a() and b() then looks:

  STATE1:

	ops_a->func_stack -> list(a3,a2,a1);
	ops_b->func_stack -> list(b3);

  STATE2:
	ops_a->func_stack -> list(a3,a2,a1);
	ops_b->func_stack -> list(b2,b1,b3);

therefore, b2() is used for the module but a3() is used for vmcore
because they were the last added.

Example of the race with going modules:
=======================================

CPU0					CPU1

delete_module()  #SYSCALL

   try_stop_module()
     mod->state = MODULE_STATE_GOING;

   mutex_unlock(&module_mutex);

					klp_register_patch()
					klp_enable_patch()

					#save place to switch universe

					b()     # from module that is going
					  a()   # from core (patched)

   mod->exit();

Note that the function b() can be called until we call mod->exit().

If we do not apply patch against b() because it is in MODULE_STATE_GOING,
it will call patched a() with modified semantic and things might get wrong.

Steffen Klassert says:

====================
pull request (net): ipsec 2015-03-16

1) Fix the network header offset in _decode_session6
   when multiple IPv6 extension headers are present.
   From Hajime Tazaki.

2) Fix an interfamily tunnel crash. We set outer mode
   protocol too early and may dispatch to the wrong
   address family. Move the setting of the outer mode
   protocol behind the last accessing of the inner mode
   to fix the crash.

3) Most callers of xfrm_lookup() expect that dst_orig
   is released on error. But xfrm_lookup_route() may
   need dst_orig to handle certain error cases. So
   introduce a flag that tells what should be done in
   case of error. From Huaibin Wang.

Please pull or let me know if there are problems.

Linus Torvalds 1ee89c519a The clk fixes for 4.0-rc4 comprise three themes. First are the usual
driver fixes for new regressions since v3.19. Second are fixes to the
 common clock divider type caused by recent changes to how we round clock
 rates. This affects many clock drivers that use this common code.
 Finally there are fixes for drivers that improperly compared struct clk
 pointers (drivers must not deref these pointers). While some of these
 drivers have done this for a long time, this did not cause a problem
 until we started generating unique struct clk pointers for every
 consumer. A new function, clk_is_match was introduced to get these
 drivers working again and they are fixed up to no longer deref the
 pointers themselves.

Christoffer Dall ae705930fc arm/arm64: KVM: Keep elrsr/aisr in sync with software model
There is an interesting bug in the vgic code, which manifests itself
when the KVM run loop has a signal pending or needs a vmid generation
rollover after having disabled interrupts but before actually switching
to the guest.

In this case, we flush the vgic as usual, but we sync back the vgic
state and exit to userspace before entering the guest.  The consequence
is that we will be syncing the list registers back to the software model
using the GICH_ELRSR and GICH_EISR from the last execution of the guest,
potentially overwriting a list register containing an interrupt.

This showed up during migration testing where we would capture a state
where the VM has masked the arch timer but there were no interrupts,
resulting in a hung test.

Alexey Kodanev 40fb70f3aa vxlan: fix wrong usage of VXLAN_VID_MASK
commit dfd8645ea1 wrongly assumes that VXLAN_VDI_MASK includes
eight lower order reserved bits of VNI field that are using for remote
checksum offload.

Right now, when VNI number greater then 0xffff, vxlan_udp_encap_recv()
will always return with 'bad_flag' error, reducing the usable vni range
from 0..16777215 to 0..65535. Also, it doesn't really check whether RCO
bits processed or not.

Fix it by adding new VNI mask which has all 32 bits of VNI field:
24 bits for id and 8 bits for other usage.

Current approach in handling shadow memory for modules is broken.

Shadow memory could be freed only after memory shadow corresponds it is no
longer used.  vfree() called from interrupt context could use memory its
freeing to store 'struct llist_node' in it:

    void vfree(const void *addr)
    {
    ...
        if (unlikely(in_interrupt())) {
            struct vfree_deferred *p = this_cpu_ptr(&vfree_deferred);
            if (llist_add((struct llist_node *)addr, &p->list))
                    schedule_work(&p->wq);

Later this list node used in free_work() which actually frees memory.
Currently module_memfree() called in interrupt context will free shadow
before freeing module's memory which could provoke kernel crash.

So shadow memory should be freed after module's memory.  However, such
deallocation order could race with kasan_module_alloc() in module_alloc().

Free shadow right before releasing vm area.  At this point vfree()'d
memory is not used anymore and yet not available for other allocations.
New VM_KASAN flag used to indicate that vm area has dynamically allocated
shadow memory so kasan frees shadow only if it was previously allocated.

Eric Dumazet c29390c6df xps: must clear sender_cpu before forwarding
John reported that my previous commit added a regression
on his router.

This is because sender_cpu & napi_id share a common location,
so get_xps_queue() can see garbage and perform an out of bound access.

We need to make sure sender_cpu is cleared before doing the transmit,
otherwise any NIC busy poll enabled (skb_mark_napi_id()) can trigger
this bug.

Michael Turquette 3d3801effd clk: introduce clk_is_match
Some drivers compare struct clk pointers as a means of knowing
if the two pointers reference the same clock hardware. This behavior is
dubious (drivers must not dereference struct clk), but did not cause any
regressions until the per-user struct clk patch was merged. Now the test
for matching clk's will always fail with per-user struct clk's.

clk_is_match is introduced to fix the regression and prevent drivers
from comparing the pointers manually.

Pull workqueue fix from Tejun Heo:
 "One fix patch for a subtle livelock condition which can happen on
  PREEMPT_NONE kernels involving two racing cancel_work calls.  Whoever
  comes in the second has to wait for the previous one to finish.  This
  was implemented by making the later one block for the same condition
  that the former would be (work item completion) and then loop and
  retest; unfortunately, depending on the wake up order, the later one
  could lock out the former one to finish by busy looping on the cpu.

  This is fixed by implementing explicit wait mechanism.  Work item
  might not belong anywhere at this point and there's remote possibility
  of thundering herd problem.  I originally tried to use bit_waitqueue
  but it didn't work for static work items on modules.  It's currently
  using single wait queue with filtering wake up function and exclusive
  wakeup.  If this ever becomes a problem, which is not very likely, we
  can try to figure out a way to piggy back on bit_waitqueue"

Marc Zyngier f54b97ed0b irqchip: gicv3-its: Allocate enough memory for the full range of DeviceID
The ITS table allocator is only allocating a single page per table.
This works fine for most things, but leads to silent lack of
interrupt delivery if we end-up with a device that has an ID that is
out of the range defined by a single page of memory. Even worse, depending
on the page size, behaviour changes, which is not a very good experience.

A solution is actually to allocate memory for the full range of ID that
the ITS supports. A massive waste memory wise, but at least a safe bet.

Tested on a Phytium SoC.

Peter Hurley 2bb785169e serial: core: Fix iotype userspace breakage
commit 3ffb1a8193 ("serial: core: Add big-endian iotype")
re-numbered userspace-dependent values; ioctl(TIOCSSERIAL) can
assign the port iotype (which is expected to match the selected
i/o accessors), so iotype values must not be changed.

Linus Torvalds af13e86713 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
 "Radeon, imx, msm, and i915 fixes.

  The msm, imx and i915 ones are fairly run of the mill.

  Radeon had some DP audio and posting reads for irq fixes, along with a
  fix for 32-bit kernels with new cards, we were using unsigned long to
  represent GPU side memory space, but since that changed size on 32 vs
  64 cards with lots of VRAM failed, so the change has no effect on
  x86-64, just moves to using uint64_t instead"

Linus Torvalds 39ed853a24 Power management and ACPI fixes for v4.0-rc3
- Fix ACPI resources management problems introduced by the recent
    rework of the code in question (Jiang Liu) and a build issue
    introduced by those changes (Joachim Nilsson).
 
  - Fix a recent suspend-to-idle regression on systems where entering
    idle states causes local timers to stop, prevent suspend-to-idle
    from crashing in restricted configurations (no cpuidle driver,
    cpuidle disabled etc.) and clean up the idle loop somewhat while
    at it (Rafael J Wysocki).
 
  - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
 
  - Allow the ACPI backlight driver module to be loaded if ACPI is
    disabled which helps the i915 driver in those configurations
    (stable-candidate) and change the code to help debug unusual use
    cases (Chris Wilson).
 
  - Wakeup IRQ management changes in v3.18 caused some drivers on the
    at91 platform to trigger a warning from the IRQ core related to
    an unexpected combination of interrupt action handler flags.
    However, on at91 a timer IRQ is shared with some other devices
    (including system wakeup ones) and that leads to the unusual
    combination of flags in question.  To make it possible to avoid
    the warning introduce a new interrupt action handler flag (which
    can be used by drivers to indicate the special case to the core)
    and rework the problematic at91 drivers to use it and work as
    expected during system suspend/resume.  From Boris Brezillon,
    Rafael J Wysocki and Mark Rutland.
 
  - Clean up the generic power domains subsystem's debugfs interface
    (Kevin Hilman).

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes for recent regressions (ACPI resources management,
  suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes
