The documentation for efi=old_map in Documentation/admin-guide/kernel-parameters.txt was recently touched and differs between linux-next and the mainline tree. I will send a separate patch to fix the documentation when this gets accepted. The UV1 platform has been out of support for a number of years, has not had a BIOS update for at least 5 years, and we have not had access to hardware to test changes on for a while now, either. Removing the UV1 platform will improve the clarity of the changes we would like to make for our forthcoming UV5 Sapphire Rapids platform, making them easier to review. And removing the UV1 platform allows this patch set to also remove the efi=old_map boot option, which seems to be a natural progression from commit 1f299fad1e312947c974 ("efi/x86: Limit EFI old memory map to SGI UV machines") Changes for v2: - Diffstats regenerated so they should be accurate now. - Removed unused variable timeout_base_ns in tlb_uv.c found by lkp@intel.com - added x86 subsystem to subject line.
