[Xen-devel] [PATCH v3 3/3] xc_cpuid_x86.c: Remove conditional for SYSCALL masking

[Zhuo Song <alfred.z.song@xxxxxxxxx>]

vmx_cpuid_intercept() has covered it when vmexit and original is_64bit
or is_pae could not cover whether guest OS is really in long mode or not.
Here to leave it to vmexit handler to do the real work.
