0d20299dbb Merge tag 'drm-intel-fixes-2013-06-24' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes
One remaining regression fix for i915. I've left it in -fixes for more
than a week since it's in tricky code, and it took us a few kernel
releases to notice the regression at all. The fence leak is especially
annoying on gen2/3 and will kill userspace there quickly. For extra
paranoia we've added a WARN in -next to catch this, things seem to be
solid now.

bb69ee27b9 [media] Fix build when drivers are builtin and frontend modules
There are a large number of reports that the media build is

the needed frontends are compiled as module.

This is happening because a builtin module can't use directly a symbol
found on a module. By enabling CONFIG_MEDIA_ATTACH, the configuration
becomes valid, as dvb_attach() macro loads the module if needed, making
the symbol available to the builtin module.

While this bug started to appear after the patches that use IS_DEFINED
macro (like changeset 7b34be71db), this
bug is a way ancient than that.

The thing is that, before the IS_DEFINED() patches, the logic used to be:

       && defined(MODULE))
struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
					u8 i2c_addr,
					struct i2c_adapter *i2c);
static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
					u8 i2c_addr,
					struct i2c_adapter *i2c)
{
	printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__);
	return NULL;
}

The above code, with the .config file used, was evoluting to FALSE
(instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'),
and were adding the static inline code at saa7134-dvb, instead
of the external call. So, while it weren't producing any compilation
error, the code weren't working either.

So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just
enable it, if MODULES is defined.

8b6fd65264 irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN case
Commit c011470 (irqchip: gic: Perform the gic_secondary_init() call via
CPU notifier) moves gic_secondary_init() that used to be called in
.smp_secondary_init hook into a notifier call.  But it changes the
system behavior a little bit.  Before the commit, gic_cpu_init()
is called not only when kernel brings up the secondary cores but also
when system resuming procedure hot-plugs the cores back to kernel.
While after the commit, the function will not be called in the latter
case, where the 'action' will not be CPU_STARTING but
CPU_STARTING_FROZEN.  This behavior difference at least causes the
following suspend/resume regression on imx6q.

b52e0a7c4e x86: Fix trigger_all_cpu_backtrace() implementation
The following change fixes the x86 implementation of
trigger_all_cpu_backtrace(), which was previously (accidentally,
as far as I can tell) disabled to always return false as on
architectures that do not implement this function.

trigger_all_cpu_backtrace(), as defined in include/linux/nmi.h,
should call arch_trigger_all_cpu_backtrace() if available, or
return false if the underlying arch doesn't implement this
function.

x86 did provide a suitable arch_trigger_all_cpu_backtrace()
implementation, but it wasn't actually being used because it was
declared in asm/nmi.h, which linux/nmi.h doesn't include. Also,
linux/nmi.h couldn't easily be fixed by including asm/nmi.h,
because that file is not available on all architectures.

I am proposing to fix this by moving the x86 definition of
arch_trigger_all_cpu_backtrace() to asm/irq.h.

Tested via: echo l > /proc/sysrq-trigger

Before the change, this uses a fallback implementation which
shows backtraces on active CPUs (using
smp_call_function_interrupt() )

After the change, this shows NMI backtraces on all CPUs

instead, it should use:

Book3E uses the hugepd at PMD level and don't encode pte directly
at the pmd level. So it will find the lower bits of pmd set
and the pmd_bad check throws error. Infact the current code
will never take the free_hugepd_range call at all because it will
clear the pmd if it find a hugepd pointer. Fix this by clearing
bad pmd only if it is not a hugepd pointer.

b9e95fc65e ACPI / LPSS: Power up LPSS devices during enumeration
Commit 7cd8407 (ACPI / PM: Do not execute _PS0 for devices without
_PSC during initialization) introduced a regression on some systems
with Intel Lynxpoint Low-Power Subsystem (LPSS) where some devices
need to be powered up during initialization, but their device objects
in the ACPI namespace have _PS0 and _PS3 only (without _PSC or power
resources).

To work around this problem, make the ACPI LPSS driver power up
devices it knows about by using a new helper function
acpi_device_fix_up_power() that does all of the necessary
sanity checks and calls acpi_dev_pm_explicit_set() to put the
device into D0.

Commit 781d737 (ACPI: Drop power resources driver) introduced a
bug in the power resources initialization error code path causing
a NULL pointer to be referenced in acpi_release_power_resource()
if there's an error triggering a jump to the 'err' label in
acpi_add_power_resource().  This happens because the list_node
field of struct acpi_power_resource has not been initialized yet
at this point and doing a list_del() on it is a bad idea.

To prevent this problem from occuring, initialize the list_node
field of struct acpi_power_resource upfront.

8112006f41 ACPI / dock: Take ACPI scan lock in write_undock()
Since commit 3757b94 (ACPI / hotplug: Fix concurrency issues and
memory leaks) acpi_bus_scan() and acpi_bus_trim() must always be
called under acpi_scan_lock, but currently the following scenario
violating that requirement is possible:

 write_undock()
  handle_eject_request()
   hotplug_dock_devices()
    dock_remove_acpi_device()
     acpi_bus_trim()

Fix that by making write_undock() acquire acpi_scan_lock before
calling handle_eject_request() as appropriate (begin_undock() is
under the lock too in analogy with acpi_dock_deferred_cb()).

204ebc0aa3 ACPI / resources: call acpi_get_override_irq() only for legacy IRQ resources
acpi_get_override_irq() was added because there was a problem with
buggy BIOSes passing wrong IRQ() resource for the RTC IRQ.  The
commit that added the workaround was 61fd47e0c8 (ACPI: fix two
IRQ8 issues in IOAPIC mode).

With ACPI 5 enumerated devices there are typically one or more
extended IRQ resources per device (and these IRQs can be shared).
However, the acpi_get_override_irq() workaround forces all IRQs in
range 0 - 15 (the legacy ISA IRQs) to be edge triggered, active high
as can be seen from the dmesg below:

	ACPI: IRQ 6 override to edge, high
	ACPI: IRQ 7 override to edge, high
	ACPI: IRQ 7 override to edge, high
	ACPI: IRQ 13 override to edge, high

Also /proc/interrupts for the I2C controllers (INT33C2 and INT33C3) shows
the same thing:

	7:          4          0          0          0   IO-APIC-edge INT33C2:00, INT33C3:00

The _CSR method for INT33C2 (and INT33C3) device returns following
resource:

	Interrupt (ResourceConsumer, Level, ActiveLow, Shared,,, )
	{
		0x00000007,
	}

which states that this is supposed to be level triggered, active low,
shared IRQ instead.

Fix this by making sure that acpi_get_override_irq() gets only called
when we are dealing with legacy IRQ() or IRQNoFlags() descriptors.

While we are there, correct pr_warning() to print the right triggering
value.

This change turns out to be necessary to make DMA work correctly on
systems based on the Intel Lynxpoint PCH (Platform Controller Hub).

949785996e x86: Fix section mismatch on load_ucode_ap
We are in the process of removing all the __cpuinit annotations.
While working on making that change, an existing problem was
made evident:

  WARNING: arch/x86/kernel/built-in.o(.text+0x198f2): Section mismatch
  in reference from the function cpu_init() to the function
  .init.text:load_ucode_ap()   The function cpu_init() references
  the function __init load_ucode_ap().  This is often because cpu_init
  lacks a __init annotation or the annotation of load_ucode_ap is wrong.

This now appears because in my working tree, cpu_init() is no longer
tagged as __cpuinit, and so the audit picks up the mismatch.  The 2nd
hypothesis from the audit is the correct one, as there was an incorrect
__init tag on the prototype in the header (but __cpuinit was used on
the function itself.)

The audit is telling us that the prototype's __init annotation took
effect and the function did land in the .init.text section.  Checking
with objdump on a mainline tree that still has __cpuinit shows that
the __cpuinit on the function takes precedence over the __init on the
prototype, but that won't be true once we make __cpuinit a no-op.

Even though we are removing __cpuinit, we temporarily align both
the function and the prototype on __cpuinit so that the changeset
can be applied to stable trees  if desired.

c0691143df mn10300: Fix include dependency in irqflags.h et al.
We need to pick up the definition of raw_smp_processor_id() from
asm/smp.h.  For the !SMP case, we need to supply a definition of
raw_smp_processor_id().

Because of the include dependencies we cannot use smp_call_func_t in
asm/smp.h, but we do need linux/thread_info.h

418a133b71 metag: fix mm/hugetlb.c build breakage
Commit 106c992a5e ("mm/hugetlb: add more arch-defined huge_pte
functions") added an include of <asm-generic/hugetlb.h> to each
architecture's <asm/hugetlb.h> (except s390).  Unfortunately metag was
missed which resulted in build errors when hugetlbfs is enabled (see
below).

Add the include for metag too to fix the build errors:

  mm/hugetlb.c In function 'make_huge_pte':
  mm/hugetlb.c +2250 : error: implicit declaration of function 'huge_pte_mkwrite'
  mm/hugetlb.c +2250 : error: implicit declaration of function 'huge_pte_mkdirty'
  ...

 "The larger changes this time are

   - "ARM: 7755/1: handle user space mapped pages in flush_kernel_dcache_page"
     which fixes more data corruption problems with O_DIRECT

   - "ARM: 7759/1: decouple CPU offlining from reboot/shutdown" which
     gets us back to working shutdown/reboot on SMP platforms

   - "ARM: 7752/1: errata: LoUIS bit field in CLIDR register is incorrect"
     which fixes a shutdown regression found in v3.10 on Versatile
     Express platforms.

  The remainder are the quite small, maybe one or two line changes"

722a860ecb [media] exynos4-is: Fix FIMC-IS clocks initialization
The ISP clock register content is not preserved over the ISP power domain
off/on cycle. Instead of setting the clock frequencies once at probe time
the clock rates set up is moved to the runtime_resume handler, which is
invoked after the related power domain is already enabled, ensuring the
clocks are properly configured when the device is actively used.
This fixes the FIMC-IS malfunctions and STREAM ON timeout errors accuring
on some boards:
[ 59.860000] fimc_is_general_irq_handler:583 ISR_NDONE: 5: 0x800003e8, IS_ERROR_UNKNOWN
[ 59.860000] fimc_is_general_irq_handler:586 IS_ERROR_TIME_OUT
