Subject: [PATCH v2 resend 2/2] xc_cpuid_x86.c: Remove limit for RDTSCP
Date: Tue, 9 Sep 2014 15:55:49 +0800 [thread overview]
Message-ID: <1410249349-21652-2-git-send-email-alfred.z.song@gmail.com> (raw)
Since RDTSCP could be used for both 64-bit and 32-bit architectures,
we do not need the tying to 64-bit in intel_xc_cpuid_policy().
