Philipp Stanner 1f829359c8 KVM: Harden copying of userspace-array against overflow ... kvm_main.c utilizes vmemdup_user() and array_size() to copy a userspace array. Currently, this does not check for an overflow. Use the new wrapper vmemdup_array_user() to copy the array more safely. Note, KVM explicitly checks the number of entries before duplicating the array, i.e. adding the overflow check should be a glorified nop.
