From b232c7857aa36d144205134c725114541630b1c2 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Tue, 6 Oct 2015 14:30:57 +1100 Subject: kvm-all: Align to qemu_real_host_page_size in kvm_set_phys_mem As the comment in kvm_set_phys_mem() says, KVM works in page size chunks. However it uses hardcoded TARGET_PAGE_SIZE which is 4K on most platforms while actual host may use different page size, for example, PPC64 hosts use 64K system pages. This replaces static TARGET_PAGE_SIZE with run-time calculated qemu_real_host_page_size.
