2017-03-02sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar1-0/+1
<linux/sched/task_stack.h> We are going to split <linux/sched/task_stack.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/task_stack.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

2017-01-30mtd: nand: fsmc: remove stale non-DT probe pathLinus Walleij2-21/+133
The FSMC driver has an execution path and a header file in <linux/mtd/fsmc.h> that serves to support passing in platform data through board files, albeit no upstream users of this mechanism exist. The header file also contains function headers for functions that do not exist in the kernel. Delete this and move the platform data struct, parsing and handling into the driver, assume we are using OF and make the driver depend on OF, remove the ifdefs making that optional.

Semantics of NR_IRQS is different on machines with SPARSE_IRQ option disabled or enabled, in the latter case IRQs are allocated starting at least from the value specified by NR_IRQS and going upwards, so the check of (irq >= NR_IRQ) to decide about an error code returned by platform_get_irq() is completely invalid, don't attempt to overrule irq subsystem in the driver.
