Maciej S. Szmigiero f5756029ee KVM: x86: Use nr_memslot_pages to avoid traversing the memslots array ... 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.
