[Xen-devel] [PATCH v2 2/3] x86/vmx: optimize vmx_read/write_guest_msr()

Replace linear scan with vmx_find_msr(). This way the time complexity of searching for required MSR reduces from linear to logarithmic. Signed-off-by: Sergey Dyasli --- v1 --> v2: - a new patch, factored out from v1 1/2 xen/arch/x86/hvm/vmx/vmcs.c | 26
