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 7b34be71), 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.

Commit c0114709 (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. $ echo mem > /sys/power/state PM: Syncing filesystems ... done.

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 Signed-off-by: NMichel Lespinasse <walken@google.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: http://lkml.kernel.org/r/1370518875-1346-1-git-send-email-walken@google.comSigned-off-by: NIngo Molnar <mingo@kernel.org>

With this change, we no longer lose the innermost entry in the user-mode part of the call chain. See also the x86 port, which includes the ip, and the corresponding change in arch/arm.

The $obj-m/$obj-y vars should be adding new modules to build, not overriding it. So, it should never use $obj-y := foo.o instead, it should use: $obj-y += foo.o Failing to do that is very bad, as it will suppress needed modules. Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

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.

Commit 7cd8407d (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 781d737c (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.
