The following commit has been merged into the x86/cpu branch of tip: Commit-ID: 182ecfaf757de234a5262f51c0e699bec7258a67 Gitweb: https://git.kernel.org/tip/182ecfaf757de234a5262f51c0e699bec7258a67 Author: Tony Luck <tony.luck@xxxxxxxxx> AuthorDate: Mon, 31 Jan 2022 15:01:10 -08:00 Committer: Borislav Petkov <bp@xxxxxxx> CommitterDate: Tue, 01 Feb 2022 16:35:21 +01:00 topology/sysfs: Add format parameter to macro defining "show" functions for proc All the simple (non-mask and non-list files in /sys/devices/system/cpu/cpu0/topology/ are currently printed as decimal integers. Refactor the macro that generates the "show" functions to take a format parameter to allow future files to display in other formats. No functional change.
