The current size of vDSO code mapping is hardcoded to PAGE_SIZE. This cannot work for 4KB page size after commit18efd0b10e("LoongArch: vDSO: Wire up getrandom() vDSO implementation") because the code size increases to 8KB. Thus set the code mapping size to its real size, i.e. PAGE_ALIGN(vdso_end - vdso_start).

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.
