Commit69896119dc("MIPS: vdso: Switch to generic storage implementation") switches to a generic vdso storage, which increases the number of data pages from 1 to 4. But there is only one page reserved, which causes segementation faults depending where the VDSO area is randomized to. To fix this use the same size of reservation and allocation of the VDSO data pages.

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 reStructuredText 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.
