Aneesh Kumar K.V a092a03fa9 powerpc/mm: Print kernel map details to dmesg
This helps in debugging. We can look at the dmesg to find out
different kernel mapping details.

On 4K config this shows

 kernel vmalloc start   = 0xc000100000000000
 kernel IO start        = 0xc000200000000000
 kernel vmemmap start   = 0xc000300000000000

On 64K config:

 kernel vmalloc start   = 0xc008000000000000
 kernel IO start        = 0xc00a000000000000
 kernel vmemmap start   = 0xc00c000000000000

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.
