[Xen-devel] [PATCH Altp2m cleanup v5 0/3] Cleaning up altp2m code

[Paul Lai <paul.c.lai@xxxxxxxxx>]

Altp2m cleanup work

The altp2m clean work is motivated by the following URLs:
   https://lists.xenproject.org/archives/html/xen-devel/2015-07/msg04323.html
   https://lists.xenproject.org/archives/html/xen-devel/2015-07/msg04454.html
   https://lists.xenproject.org/archives/html/xen-devel/2015-07/msg04530.html

Most of the work has been:
Lots of white space, indentation, and other coding style preference
corrections.
Lots of moving altp2m functions to the altp2m file.
Lots of moving ept functions to the ept file.
Lots of function return type corrections (and checking).
Better sanity checking of values before processing in do_altp2m_op().
Just using 'return' after a if() clause instead of using a goto
if the block is can be a one liner.

Most importantly here, we help submit Ravi Sahita's dynamically allocated
altp2m domain for struct p2m.  Also, Ravi introduces set_altp2m_active()
and altp2m_active() APIs for better readability and maintainability.

Along the way, some dependencies have broken and we've waited for them
to be fixed.  Most recently the gfn() which caused a hang of the whole system.
The gfn fixes are currently in staging. We've have verified against the
staging branch that this series of patches functions as expected.
