From: Tony Luck <tony.luck@xxxxxxxxx> [ Upstream commit 2eda374e883ad297bd9fe575a16c1dc850346075 ] New CPU #defines encode vendor and family as well as model.

Now pr_info("Incomplete global flushes, disabling PCID") is back in dmesg. I also tested on a Meteor Lake system, which is not affected by the INVLPG issue. The message in question is not there before and after the backport, as expected. This backport fixes the last remaining caller of x86_match_cpu() that does not use the family of X86_MATCH_*() macros. Thomas Lindroth intially reported the regression in https://lore.kernel.org/all/eb709d67-2a8d-412f-905d-f3777d897bfa@xxxxxxxxx/ Maybe Tony and/or the x86 maintainers can ack this backport? --- arch/x86/mm/init.c | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/arch/x86/mm/init.c b/arch/x86/mm/init.c index 679893ea5e68..6215dfa23578 100644 --- a/arch/x86/mm/init.c +++ b/arch/x86/mm/init.c @@ -261,21 +261,17 @@ static void __init probe_page_size_mask(void) } } -#define INTEL_MATCH(_model) { .vendor = X86_VENDOR_INTEL, \ - .family = 6, \ - .model = _model, \ - } /* * INVLPG may not properly flush Global entries * on these CPUs when PCIDs are enabled. */ static const struct x86_cpu_id invlpg_miss_ids[] = { - INTEL_MATCH(INTEL_FAM6_ALDERLAKE ), - INTEL_MATCH(INTEL_FAM6_ALDERLAKE_L ), - INTEL_MATCH(INTEL_FAM6_ATOM_GRACEMONT ), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE ), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE_P), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE_S), + X86_MATCH_INTEL_FAM6_MODEL(ALDERLAKE, 0), + X86_MATCH_INTEL_FAM6_MODEL(ALDERLAKE_L, 0), + X86_MATCH_INTEL_FAM6_MODEL(ATOM_GRACEMONT, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE_P, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE_S, 0), {} }; -- 2.34.1
