From: Zhang Xiantao <[EMAIL PROTECTED]> Date: Sat, 8 Dec 2007 10:38:04 +0800 Subject: [PATCH] kvm: qemu : Changing memory align size to TARGET_PAGE_SIZE.
Since other cpus may use big page size, allocated memory must
bed aligned with host page size. Otherwise, it will block userspace
memory allocatoin mechanism.
