I also kept the ALDERLAKE_N name instead of ATOM_GRACEMONT. Both refer to the same CPU model. ] Signed-off-by: Ricardo Neri ricardo.neri-calderon@linux.intel.com --- I tested this backport on an Alder Lake system. Now pr_info("Incomplete global flushes, disabling PCID") is back in dmesg. I also tested on a Meteor Lake system, which unaffected by the INVLPG issue. The message in question is not there before and after the backport, as expected. --- arch/x86/mm/init.c | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-)
