Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined (which is the case for PA-RISC), __kunmap_local() calls kunmap_flush_on_unmap(), which may call the parisc flush functions with a non-page-aligned address and thus the page might not be fully flushed. This patch ensures that flush_kernel_dcache_page_asm() and flush_kernel_dcache_page_asm() will always operate on page-aligned addresses.

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.
