So we can use the context switch callback to flush LBR stack. This patch adds code that uses the flush branch callback to flush the LBR stack when task is being scheduled in. The callback is enabled only when there are events use the LBR hardware. This patch also removes all old flush branch stack code.

To enable this feature, bits (JCC, NEAR_IND_JMP, NEAR_REL_JMP, FAR_BRANCH, EN_CALLSTACK) in LBR_SELECT must be set to 1, bits (NEAR_REL_CALL, NEAR-IND_CALL, NEAR_RET) must be cleared. Due to a hardware bug of Haswell, this feature doesn't work well with FREEZE_LBRS_ON_PMI. When the call stack feature is enabled, the LBR stack will capture unfiltered call data normally, but as return instructions are executed, the last captured branch record is flushed from the on-chip registers in a last-in first-out (LIFO) manner. Thus, branch information relative to leaf functions will not be captured, while preserving the call stack information of the main line execution path. This patch defines a separate lbr_sel map for Haswell. The map contains a new entry for the call stack feature.

The solution is saving/restoring the LBR stack to/from task's perf event context. The LBR stack is saved/restored only when there are events that use the LBR call stack. If no event uses LBR call stack, the LBR stack is reset when task is scheduled in.

ARM relies on the standard implementation of pci_resource_to_user() which actually is an identity map and exports to user space PCI memory resources as they are stored in PCI devices resources structures, which represent CPU physical addresses (fixed-up using BUS to CPU address conversions) not PCI bus addresses. Therefore, on ARM platforms where the mapping between CPU and BUS address is not a 1:1 the current pci_mmap_page_range() implementation is erroneous, in that an additional shift is applied to an already fixed-up offset passed from userspace. Hence, this patch removes the mem_offset from the pgoff calculation since the offset as passed from user space already represents the CPU physical address corresponding to the resource to be mapped, ie no additional offset should be applied.

At that time, the irq domains for the interrupt controllers referenced by its interrupts-extended property cannot be found yet: irq: no irq domain found for /interrupt-controller@e61c0000 ! Nevertheless, the core OF probing code ignores this failure, besides a debug message that's not normally printed: not all legacy IRQ resources mapped for pfc and continues initialization of the device. Then, the sh-pfc driver cannot find any IRQ resources, and thinks no interrupts are available, causing gpio-keys to fail later: gpio-keys keyboard: Unable to claim irq 0; error -22 gpio-keys: probe of keyboard failed with error -22 Move the pin function controller node after the interrupt controller nodes it references to work around the bug in the core OF probing code.
