Subject: [PATCH 4.9 029/151] KVM/x86: Fix invvpid and invept register operand size in 64-bit mode

From: Uros Bizjak <ubizjak@...il.com>

[ Upstream commit 5ebb272b2ea7e02911a03a893f8d922d49f9bb4a ]

Register operand size of invvpid and invept instruction in 64-bit mode
has always 64 bits. Adjust inline function argument type to reflect
correct size.
