2012-06-16sh/PCI: move fixup hooks from __init to __devinitSebastian Andrzej Siewior1-1/+1
The fixups are executed once the pci-device is found which is during boot process so __init seems fine as long as the platform does not support hotplug. However it is possible to remove the PCI bus at run time and have it rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call the fixups again.

2012-06-14sh64: Fix up section mismatch warnings.Paul Mundt1-1/+1
WARNING: vmlinux.o(.cpuinit.text+0x280): Section mismatch in reference from the function cpu_probe() to the function .init.text:sh64_tlb_init() The function __cpuinit cpu_probe() references a function __init sh64_tlb_init(). If sh64_tlb_init is only used by cpu_probe then annotate sh64_tlb_init with a matching annotation. sh64_tlb_init() simply needs to be __cpuinit annotated, so fix that up.

2012-06-01new helper: signal_delivered()Al Viro2-4/+2
Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).
