# Commit ff22a91b4c45f9310d0ec0d7ee070d84a373dd87 # Date 2019-09-25 15:53:35 +0200 # Author Jan Beulich <jbeulich@suse.com> # Committer Jan Beulich <jbeulich@suse.com> ACPI/cpuidle: bump maximum number of power states we support Commit 4c6cd64519 ("mwait_idle: Skylake Client Support") added a table with 8 entries, which - together with C0 - rendered the current limit too low. It should have been accompanied by an increase of the constant; do this now. Don't bump by too much though, as there are a number of on- stack arrays which are dimensioned by this constant.
