| H A D | tsc.c | diff 246212 Fri Feb 01 14:49:25 MST 2013 kib The change to reduce default smp_tsc_shift caused tsc shift to become zero on slower machines, which make the fenced get_timecount methods not used despite needed. Remove the (shift > 0) condition when selecting the get_timecount() implementation. Rename smp_tsc_shift to tsc_shift, and apply it for the UP case too. Allow shift to reach value of 31 instead of 30, as it was previously (should be nop). Reorganize the tc quality calculation to remove the conditionally compiled block. Rename test_smp_tsc() to test_tsc() and provide separate versions for SMP and UP builds. The check for virtialized hardware is more natural to perform in the smp version of the test_tsc(), since it is only done for smp case.
