Revert "KVM: SVM: fix trashing of MSR_TSC_AUX"
This reverts commit 9770404a. The reverted patch is not needed as only userspace uses RDTSCP and MSR_TSC_AUX is in host_save_user_msrs[] and therefore properly saved in svm_vcpu_load() and restored in svm_vcpu_put() before every switch to userspace. The reverted patch did not allow the kernel to use RDTSCP in the future, because of missed trashing in svm_set_msr() and 64-bit ifdef. This reverts commit 2b23c3a6. 2b23c3a6 ("KVM: SVM: do not set MSR_TSC_AUX on 32-bit builds") is a build fix for 9770404a and reverting them separately would only break more bisections.
