      tracing: Fix synthetic event to allow semicolon at end · a360d9e4
      Masami Hiramatsu authored
      Fix synthetic event to allow independent semicolon at end.
      
      The synthetic_events interface accepts a semicolon after the
      last word if there is no space.
      
       # echo "myevent u64 var;" >> synthetic_events
      
      But if there is a space, it returns an error.
      
       # echo "myevent u64 var ;" > synthetic_events
       sh: write error: Invalid argument
      
      This behavior is difficult for users to understand. Let's
      allow the last independent semicolon too.

      tracing: Fix synthetic event to accept unsigned modifier · 282447ba
      Masami Hiramatsu authored
      Fix synthetic event to accept unsigned modifier for its field type
      correctly.
      
      Currently, synthetic_events interface returns error for "unsigned"
      modifiers as below;
      
       # echo "myevent unsigned long var" >> synthetic_events
       sh: write error: Invalid argument
      
      This is because argv_split() breaks "unsigned long" into "unsigned"
      and "long", but parse_synth_field() doesn't expected it.
      
      With this fix, synthetic_events can handle the "unsigned long"
      correctly like as below;
      
       # echo "myevent unsigned long var" >> synthetic_events
       # cat synthetic_events
       myevent	unsigned long var

      arm64: KVM: Guests can skip __install_bp_hardening_cb()s HYP work · 4debef55
      James Morse authored
      enable_smccc_arch_workaround_1() passes NULL as the hyp_vecs start and
      end if the HVC conduit is in use, and ARM_SMCCC_ARCH_WORKAROUND_1 is
      detected.
      
      If the guest kernel happened to be built with KVM_INDIRECT_VECTORS,
      we go on to allocate a slot, memcpy() the empty workaround in and
      do the appropriate cache maintenance.
      
      This works as we always tell memcpy() the range is 0, so it never
      accesses the NULL src pointer, but we still do the cache maintenance.
      
      If hyp_vecs_start is NULL we know we're a guest, just update the fn
      like the !KVM_INDIRECT_VECTORS version.

      The calculated ideal rate can easily overflow an unsigned long, thus
      making the best div selection buggy as soon as no ideal match is found
