clangd reports many "unused header" warnings throughout the Xe driver. Start working to clean this up by removing unnecessary includes in our .c files and/or replacing them with explicit includes of other headers that were previously being included indirectly. By far the most common offender here was unnecessary inclusion of xe_gt.h. That likely originates from the early days of xe.ko when xe_mmio did not exist and all register accesses, including those unrelated to GTs, were done with GT functions. There's still a lot of additional #include cleanup that can be done in the headers themselves; that will come as a followup series. v2: - Squash the 79-patch series down to a single patch.
