5445166384 EDAC: Fix EDAC Kconfig menu
After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering
the "Device Drivers" toplevel menu in menuconfig, the suboptions behind
EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig
bool which was defined after the menu definition.

When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.

Drop a useless menuconfig comment while at it.

311bd84247 EDAC: Fix kernel panic on module unloading
This patch fixes use-after-free and double-free bugs in
edac_mc_sysfs_exit(). mci_pdev has single reference and put_device()
calls mc_attr_release() which calls kfree(). The following
device_del() works with already released memory. An another kfree() in
edac_mc_sysfs_exit() releses the same memory again. Great.

d1f9809ed1 drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks
vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI
configuration space is not restored correctly, resulting in MSI not working after switch.

Only useful item in dmesg is:

[   33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3

I did some testing, dumping the difference in ms between first succesful switch
from D3 to D0, and it seems that there is slightly more than 20 ms difference when
the device is re-enabled through vga-switcheroo.

So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working
on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

28998afa13 drm/exynos: fimd: modify condition in fimd resume
If fimd is runtime suspended (by DPMS OFF), fimd_suspend does not
call fimd_activate(false) and just returns. Similarily the check in
fimd_resume should not resume if previously runtime_suspended.
Instead the existing check does the opposite. So if fimd was not
runtime suspended, suspend will turn off fimd but resume will not turn
it on.  This patch fixes this issue by reversing the condition.

dab9206445 dma: mv_xor: fix error handling for clocks
When a channel fails to initialize, we release all ressources,
including clocks. However, a XOR unit is not necessarily associated to
a clock (some variants of Marvell SoCs have a clock for XOR units,
some don't), so we shouldn't unconditionally be releasing the clock.

Instead, just like we do in the mv_xor_remove() function, we should
check if one clock was found before releasing it.

ab6e439fd0 dma: mv_xor: fix error handling of mv_xor_channel_add()
When mv_xor_channel_add() fails for one XOR channel, we jump to the
err_channel_add label to clean up all previous channels that had been
initialized correctly. Unfortunately, while handling this error
condition, we were disposing the IRQ mapping before calling
mv_xor_channel_remove() (which does the free_irq()), which is
incorrect.

Instead, do things properly in the reverse order of the
initialization: first remove the XOR channel (so that free_irq() is
done), and then dispose the IRQ mapping.

This avoids ugly warnings when for some reason one of the XOR channel
fails to initialize.

2013-01-06 00:36:17 +01:00
Rafael J. Wysocki
9f6d8f6ab2 PM: Move disabling/enabling runtime PM to late suspend/early resume
Currently, the PM core disables runtime PM for all devices right
after executing subsystem/driver .suspend() callbacks for them
and re-enables it right before executing subsystem/driver .resume()
callbacks for them.  This may lead to problems when there are
two devices such that the .suspend() callback executed for one of
them depends on runtime PM working for the other.  In that case,
if runtime PM has already been disabled for the second device,
the first one's .suspend() won't work correctly (and analogously
for resume).

To make those issues go away, make the PM core disable runtime PM
for devices right before executing subsystem/driver .suspend_late()
callbacks for them and enable runtime PM for them right after
executing subsystem/driver .resume_early() callbacks for them.  This
way the potential conflitcs between .suspend_late()/.resume_early()
and their runtime PM counterparts are still prevented from happening,
but the subtle ordering issues related to disabling/enabling runtime
PM for devices during system suspend/resume are much easier to avoid.

87acdde56d drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c
devm_* APIs are device managed and get freed automatically when the

This patch fixes incorrect interrupt induced by m2m operation.
the m2m operation calls s/w reset every frame but there is the case that
the interrupt to m2m operation occures after s/w reset sometimes.
So this patch makes dma and capture operations stop at s/w reset
to avoid incorrect interrupt.

This patch fixes the issue that when buffer allocation is requested
without iommu, the allocation is failed.

1e15f29540 cpufreq / governor: Fix problem with cpufreq_ondemand or cpufreq_conservative
Since commit 2aacdff entitled "cpufreq: Move common part from governors
to separate file", whenever the drivers that depend on this new file
(cpufreq_ondemand or cpufreq_conservative) are built as modules, a new
module named cpufreq_governor is created because the Makefile includes
cpufreq_governor.o twice. As drivers/cpufreq/cpufreq_governor.c contains no
MODULE directives, the resulting module has no license specified, which
results in logging of a "module license 'unspecified' taints kernel". In
addition, a number of globals are exported GPL only, and are therefore
not available. This fix establishes a new boolean configuration variable
that forces cpufreq_governor.o to be linked into the kernel whenever
either cpufreq_ondemand or cpufreq_conservative is selected.

ac34d7c8c8 cpuidle: fix lock contention in the idle path
Commit bf4d1b5 (cpuidle: support multiple drivers) introduced
locking in cpuidle_get_cpu_driver(), which is used in the
idle_call() function.

This leads to a contention problem with a large number of CPUs,
because they all try to run the idle routine at the same time.

The lock can be safely removed because of how is used the cpuidle
API.  Namely, cpuidle_register_driver() is called first, but the
cpuidle idle function is not entered before cpuidle_register_device()
is called, because the cpuidle device is not enabled then. Moreover,
cpuidle_unregister_driver(), which would reset the driver value to
NULL, is not called before cpuidle_unregister_device().

All of the cpuidle drivers use the API in the same way.

In general, a cleanup around the lock is necessary and a proper
refcounting mechanism should be used to ensure the consistency in the
API (for example, cpuidle_unregister_driver() should fail if the
driver's refcount is not 0). However, these modifications will require
some code reorganization and rewrite which will be too intrusive for
a fix.

For this reason, fix the contention problem introduced by commit
bf4d1b5 by simply removing the locking from cpuidle_get_cpu_driver(),
which restores the original behavior of that routine.

The patch copies the flags masked by IORESOURCE_BITS from a resource's
template.  This is necessary because the resource settings require proper
IORESOURCE_BITS which are not known during the definition of these resources
using the "/sys/bus/pnp/*/*/resources" interface.  (In fact, they should not
be set by the user as the resource templates define the proper settings.)

If the patch is not applied, the resource flags are not initialized properly
and obscure messages in the kernel log have been seen ("invalid flags").

This patch factors out the setting of PNP resources into one function which is

avoids duplication.  The parameters "type" and "flags" are not used at the
moment but may be used by follow-up patches.  Placeholders for these patches
can be found in the comment lines that contain the "TBD" marker.

As the code does not make any changes to the ABI, no regressions are expected.

0271f4f117 ACPI / power: Remove useless message from device registering routine
After commit 71fbad6 (PCI/ACPI: Notify PCI devices when their power
resource is turned on) made acpi_pci_bind() call
acpi_power_resource_register_device(), the debug message at the end
of the latter appears in the kernel log for every PCI device that
doesn't happen to have power resources assigned (which is the vast
majority of them).  However, this message is totally useless, because
it doesn't even say which device it is about.  Moreover, it is
misleading, because it only means that the given device has no power
resources, which isn't exceptional at all.

Remove that useless message altogether and simplify
acpi_power_resource_register_device() slightly.

2d7c22f67d leds: leds-gpio: set devm_gpio_request_one() flags param correctly
commit a99d76f leds: leds-gpio: use gpio_request_one

changed the leds-gpio driver to use gpio_request_one() instead
of gpio_request() + gpio_direction_output()

Unfortunately, it also made a semantic change that breaks the
leds-gpio driver.

The gpio_request_one() flags parameter was set to:

GPIOF_DIR_OUT | (led_dat->active_low ^ state)

Since GPIOF_DIR_OUT is 0, the final flags value will just be the
XOR'ed value of led_dat->active_low and state.

This value were used to distinguish between HIGH/LOW output initial
level and call gpio_direction_output() accordingly.

With this new semantic gpio_request_one() will take the flags value
of 1 as a configuration of input direction (GPIOF_DIR_IN) and will
call gpio_direction_input() instead of gpio_direction_output().

int gpio_request_one(unsigned gpio, unsigned long flags, const char *label)
{
..
	if (flags & GPIOF_DIR_IN)
		err = gpio_direction_input(gpio);
	else
		err = gpio_direction_output(gpio,
				(flags & GPIOF_INIT_HIGH) ? 1 : 0);
..
}

The right semantic is to evaluate led_dat->active_low ^ state and
set the output initial level explicitly.
