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.

2013-06-20irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN caseShawn Guo
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. $ echo mem > /sys/power/state PM: Syncing filesystems ... done.

2013-06-20x86: Fix trigger_all_cpu_backtrace() implementationMichel Lespinasse
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: Michel 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.com Signed-off-by: Ingo 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.

2013-06-20[media] s5p makefiles: don't override other selections on obj-[ym]Mauro Carvalho Chehab
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: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-06-20powerpc: Fix bad pmd error with book3E configAneesh Kumar K.V
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.
