powerpc/cell: Make spu_flush_all_slbs() generic

2014-10-08T09:15:37Z

This moves spu_flush_all_slbs() into a generic call copro_flush_all_slbs(). This will be useful when we add cxl which also needs a similar SLB flush call. Signed-off-by: Ian Munsie Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman

powerpc/cell: Move data segment faulting code out of cell platform

2014-10-08T09:14:55Z

__spu_trap_data_seg() currently contains code to determine the VSID and ESID required for a particular EA and mm struct. This code is generically useful for other co-processors. This moves the code of the cell platform so it can be used by other powerpc code. It also adds 1TB segment handling which Cell didn't support. The new function is called copro_calculate_slb(). This also moves the internal struct spu_slb to a generic struct copro_slb which is now used in the Cell and copro code. We use this new struct instead of passing around esid and vsid parameters.

powerpc/cell: Move spu_handle_mm_fault() out of cell platform

2014-10-08T09:14:54Z

Currently spu_handle_mm_fault() is in the cell platform. This code is generically useful for other non-cell co-processors on powerpc. This patch moves this function out of the cell platform into arch/powerpc/mm so that others may use it. Signed-off-by: Ian Munsie Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman
