cxl: Add new header for call backs and structs This new header adds callbacks and structs needed by the rest of the kernel to hook into the cxl infrastructure. This adds the cxl_ctx_in_use() function for use in the mm code to see if 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. cxl_ctx_get/put/in_use are static inlined here as they are called in tlbie which we want to be fast (mpe's suggestion). Empty functions are provided when CONFIG_CXL_BASE is not enabled.

cxl: Move include file cxl.h -> cxl-base.h This moves the current include file from cxl.h -> cxl-base.h. This current include file is used only to pass information between the base driver that needs to be built into the kernel and the cxl module. This is to make way for a new include/misc/cxl.h which will contain just the kernel API for other driver to use Signed-off-by: Michael Neuling <mikey@neuling.org> Acked-by: Ian Munsie <imunsie@au1.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
