Matthew Auld	9e97874148	drm/xe/userptr: replace xe_hmm with gpusvm ... Goal here is cut over to gpusvm and remove xe_hmm, relying instead on common code. The core facilities we need are get_pages(), unmap_pages() and free_pages() for a given useptr range, plus a vm level notifier lock, which is now provided by gpusvm. v2: - Reuse the same SVM vm struct we use for full SVM, that way we can use the same lock (Matt B & Himal) v3: - Re-use svm_init/fini for userptr. v4: - Allow building xe without userptr if we are missing DRM_GPUSVM config. (Matt B) - Always make .read_only match xe_vma_read_only() for the ctx. (Dafna) v5: - Fix missing conversion with CONFIG_DRM_XE_USERPTR_INVAL_INJECT v6: - Convert the new user in xe_vm_madise.

Matthew Auld	dd25b995a2	drm/xe/vm: split userptr bits into separate file ... This will simplify compiling out the bits that depend on DRM_GPUSVM in a later patch. Without this we end up littering the code with ifdef checks, plus it becomes hard to be sure that something won't blow at runtime due to something not being initialised, even though it passed the build. Should be no functional change here.
