powerpc: declare unmodified attribute_group usages const Inspired by (bd75b4ef4977: Constify static attribute_group structs), accepted by linux-next, reported: https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20220210202805.7750-4-rikard.falkeborn@gmail.com/ Nearly all singletons of type struct attribute_group are never modified, and so are candidates for being const. Declare them as const.

arch: powerpc: Stop building and using oprofile 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. This commits stops building oprofile for powerpc and removes any reference to it from directories in arch/powerpc/ apart from arch/powerpc/oprofile, which will be removed in the next commit (this is broken into two commits as the size of the commit became very big, ~5k lines). Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't removed as it was also used by other parts of the code.

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

cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystem This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.

powerpc: Move include files to arch/powerpc/include/asm from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
