The addresses and sizes passed to vm_userspace_mem_region_add() and madvise() should be aligned to host page size, which can be 64KB on aarch64. So it's wrong by passing additional fixed 4KB memory area to various tests. Fix it by passing additional fixed 64KB memory area to various tests. We also add checks to ensure that none of host/guest page size exceeds 64KB. MEM_TEST_MOVE_SIZE is fixed up to 192KB either. With this, the following command works fine on 64KB-page-size-host and 4KB-page-size-guest. # ./memslot_perf_test -v -s 512 Signed-off-by: Gavin Shan <gshan@redhat.com> Reviewed-by: Maciej S.

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.
