  "message": "target-i386: add RDTSCP support\n\nRDTSCP reads the time stamp counter and atomically also the content\nof a 32-bit MSR, which can be freely set by the OS. This allows CPU\nlocal data to be queried by userspace.\nLinux uses this to allow a fast implementation of the getcpu()\nsyscall, which uses the vsyscall page to avoid a context switch.\nAMD CPUs since K8RevF and Intel CPUs since Nehalem support this\ninstruction.\nRDTSCP is guarded by the RDTSCP CPUID bit (Fn8000_0001:EDX[27]).\n\nSigned-off-by: Andre Przywara \u003candre.przywara@amd.com\u003e\nSigned-off-by: Aurelien Jarno \u003caurelien@aurel32.net\u003e\n",
