arch: mips: Remove CONFIG_OPROFILE support The "oprofile" user-space tools don't use the kernel OPROFILE support any more, and haven't in a long time. User-space has been converted to the perf interfaces. Remove the old oprofile's architecture specific support.

MIPS: pass non-NULL dev_id on shared request_irq() Recently all usages of setup_irq() was replaced by request_irq(). request_irq() does a few sanity checks that were not done in setup_irq(), if they fail irq registration will fail. One of the check is to ensure that non-NULL dev_id is passed in the case of shared irq. This caused malta on qemu to hang. Fix it by passing handler as dev_id to all request_irq()'s that are shared. For sni, instead of passing non-NULL dev_id, remove shared irq flags.

MIPS: Replace setup_irq() by request_irq() request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot <lkp@intel.com> of which one was reported by Thomas Bogendoerfer <tsbogend@alpha.franken.de> as well. There were a few more issues including build errors, those also have been fixed.

MIPS: Fork loongson2ef from loongson64 As later model of GSx64 family processors including 2-series-soc have similar design with initial loongson3a while loongson2e/f seems less identical, we separate loongson2e/f support code out of mach-loongson64 to make our life easier. This patch contains mostly file moving works.
