[ Upstream commit 330d8df81f3673d6fb74550bbc9bb159d81b35f7 ] Commit1a2473f0cb("kasan: improve vmalloc tests") added the vmalloc_percpu KASAN test with the assumption that __alloc_percpu always uses vmalloc internally, which is tagged by KASAN. However, __alloc_percpu might allocate memory from the first per-CPU chunk, which is not allocated via vmalloc(). As a result, the test might fail. Remove the test until proper KASAN annotation for the per-CPU allocated are added; tracked in https://bugzilla.kernel.org/show_bug.cgi?id=215019.

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.
