Mike Rapoport 1e8ffd50fd openrisc: simplify pte_alloc_one_kernel() 
The pte_alloc_one_kernel() function allocates a page using
__get_free_page(GFP_KERNEL) when mm initialization is complete and
memblock_phys_alloc() on the earlier stages.  The physical address of
the page allocated with memblock_phys_alloc() is converted to the
virtual address and in the both cases the allocated page is cleared
using clear_page().

The code is simplified by replacing __get_free_page() with
get_zeroed_page() and by replacing memblock_phys_alloc() with
memblock_alloc().

README 

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.
