The following commit has been merged into the x86/apic branch of tip: Commit-ID: 8fd2ac6c0d74f59897eeb83de72aeb3278a54ae8 Gitweb: https://git.kernel.org/tip/8fd2ac6c0d74f59897eeb83de72aeb3278a54ae8 Author: Thomas Gleixner <tglx@linutronix.de> AuthorDate: Tue, 08 Aug 2023 15:03:49 -07:00 Committer: Dave Hansen <dave.hansen@linux.intel.com> CommitterDate: Wed, 09 Aug 2023 08:10:11 -07:00 x86/xen/pv: Pretend that it found SMP configuration Unlike all other SMP configuration "parsers" XEN/PV does not set smp_found_config which is inconsistent and prevents doing proper decision logic based on this flag. Make XEN/PV pretend that it found SMP configuration.
