Pull percpu fix from Dennis Zhou: "This is just a single change to fix percpu depopulation. The code relied on depopulation code written specifically for the free path and relied on vmalloc to do the tlb flush lazily. As we're modifying the backing pages during the lifetime of a chunk, we need to also flush the tlb accordingly. Guenter Roeck reported this issue in [1] on mips. I believe we just happen to be lucky given the much larger chunk sizes on x86 and consequently less churning of this memory" Link: https://lore.kernel.org/lkml/20210702191140.GA3166599@roeck-us.net/ [1] * 'for-5.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: flush tlb in pcpu_reclaim_populated() |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
