There is no point in recalculating from scratch the total number of pages in all memslots each time a memslot is created or deleted. Use KVM's cached nr_memslot_pages to compute the default max number of MMU pages. Note that even with nr_memslot_pages capped at ULONG_MAX we can't safely multiply it by KVM_PERMILLE_MMU_PAGES (20) since this operation can possibly overflow an unsigned long variable. Write this "* 20 / 1000" operation as "/ 50" instead to avoid such overflow. Signed-off-by: Maciej S.

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.
