From 6104f472a5ea287fbdcf4644e74867dfd905a018 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Mon, 10 Dec 2012 10:33:26 -0700 Subject: [PATCH] KVM: struct kvm_memory_slot.flags -> u32 struct kvm_userspace_memory_region.flags is a u32 with a comment that bits 0 ~ 15 are visible to userspace and the other bits are reserved for kvm internal use. KVM_MEMSLOT_INVALID is the only internal use flag and it has a comment that bits 16 ~ 31 are internally used and the other bits are visible to userspace. Therefore, let's define this as a u32 so we don't waste bytes on LP64 systems. Move to the end of the struct for alignment.
