ASoC: ac97: Support multi-platform AC'97
Currently we can only have a single platform built in with AC'97 support
due to the use of a global variable to provide the bus operations. Fix
this by making that variable a pointer and having the bus drivers set the
operations prior to registering.
This is not a particularly good or nice approach but it avoids blocking
multiplatform and a real fix involves fixing the fairly deep problems
with AC'97 support - we should be converting it to a real bus.

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
7b34be71db533f3e0cf93d53cf62d036cdb5418a), 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.

irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN case
Commit
c011470 (irqchip: gic: Perform the gic_secondary_init() call via

.smp_secondary_init hook into a notifier call. But it changes the

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

CPU_STARTING_FROZEN. This behavior difference at least causes the

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

7cd8407 (ACPI / PM: Do not execute _PS0 for devices without

need to be powered up during initialization, but their device objects

To work around this problem, make the ACPI LPSS driver power up

sanity checks and calls acpi_dev_pm_explicit_set() to put the

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
61fd47e0c8476 (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).

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.
