Yeah, looks like I screwed it up slightly in the packing of these

This also moves the internal struct spu_slb to a generic struct copro_slb which
is now used in the spu and copro code. We use this new struct instead of the
us passing around esid and vsid parameters.

From: Ian Munsie
This defines structs and magic numbers required for userspace to interact with
the kernel cxl driver via /dev/cxl/afu0.0.
It adds this header file Kbuild so it's exported when doing make
headers_installs.

This is the latest version of the cxl driver. Change log below:
v3:
- Updates based on comments from mpe, benh, aneesh and offline reviews.
- Fixed bug freeing AFU IRQs that also freed the multiplexed PSL IRQ
- Change copro_flush_all_slbs to a static inline as suggested by mpe
- Implement

We need to be careful here as the current hash_page() assumes current in a few
places.

any cxl contexts are currently in use. This is used by the tlbie() to
determine if it can do local TLB invalidations or not. This also adds get/put
calls for the cxl driver module to refcount the active cxl contexts.

Some of the MSI IRQ code in pnv_pci_ioda_msi_setup() is generically useful so
split it out.
This will be used by some of the cxl PCIe code later.

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.

This function is otherwise not included in this patch, so it should
probably be removed (as the next patch removes it anyway).
Yeah, looks like I screwed it up slightly in the packing of these
patches.
Thanks.
