mainline inclusion from mainline-v6.3-rc1 commit 65248a9a category: bugfix bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I7H29Y CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=65248a9a9ee1ea2e6aad8f35253ffd9096ab81b7 Intel-SIG: commit 65248a9a perf/x86/uncore: Add a quirk for UPI on SPR Backport SPR MCC UPI uncore discovery warning fixes to OLK-5.10. ------------------------------------- The discovery table of UPI on some SPR variants, e.g., MCC, is broken. The third UPI table may includes a wrong address which points to a non-exists device. The bug impacts both UPI and M3UPI uncore PMON. Use a pre-defined UPI and M3UPI table to replace the broken table. Different BIOS may populate a device into a different domain or a different BUS. The accurate location can only be retrieved at load time. Add spr_update_device_location() to update the location of the UPI and M3UPI in the pre-defined table.
