This is a note to let you know that I have just added a patch titled percpu: free percpu allocation info for uniprocessor system to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.9. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 4d23024952c944405426229b187b572cdf9d6d7d Mon Sep 17 00:00:00 2001 From: Honggang Li <enjoymindful@gmail.com> Date: Tue, 12 Aug 2014 21:36:15 +0800 Subject: percpu: free percpu allocation info for uniprocessor system commit 3189eddbcafcc4d827f7f19facbeddec4424eba8 upstream. Currently, only SMP system free the percpu allocation info. Uniprocessor system should free it too. For example, one x86 UML virtual machine with 256MB memory, UML kernel wastes one page memory.
