5dd0b16cda("mm/vmstat: Make NR_TLB_REMOTE_FLUSH_RECEIVED available even on UP") made the availability of the NR_TLB_REMOTE_FLUSH* counters inside the kernel unconditional to reduce #ifdef soup, but (either to avoid showing dummy zero counters to userspace, or because that code was missed) didn't update the vmstat_array, meaning that all following counters would be shown with incorrect values. This only affects kernel builds with CONFIG_VM_EVENT_COUNTERS=y && CONFIG_DEBUG_TLBFLUSH=y && CONFIG_SMP=n.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
