#       "Sparc fixes:
#     
#        The main bit here is fixing how fallback system calls are handled in
#        the sparc vDSO.
#     
#        Unfortunately, I fat fingered the commit and some perf debugging
#        hacks slipped into the vDSO fix, which I revert in the very next
#        commit."
