-    rhbz1504009: let dtrace -G -o /dev/null run, as in autoconf
-    
-    commit c245153ca193c471a8c broke the ability of dtrace to be tested in
-    autoconf "-G -o /dev/null" usage, because its output file name was too
-    simple a function of the input name, and normal users can't write to
-    /dev/null.dtrace-temp.c .  Now we back down to mkstemp, like before,
-    upon a failure of the simple concatenated name.

-Subject: [PATCH] Fix PR22551 by updating the use of timers for the 4.15
- kernel.
-
-* runtime/linux/timer_compatibility.h: New file.
-* runtime/time.c: Update timer callback function parameter type. Update
-  timer initialization.
-* runtime/transport/relay_v2.c: Ditto.
-* runtime/transport/transport.c: Ditto.
-* tapset-timers.cxx (timer_derived_probe_group::emit_module_decls):
-  Ditto. Handle old and new timer callback interface.
-* runtime/linux/runtime.h: Include timer_compatibility.h instead of timer.h.
-* tapset/linux/scsi.stp: Ditto.

-+ * Starting with the 4.15 kernel, the timer interface

-+ *   timer.expires = jiffies + STP_RELAY_TIMER_INTERVAL;

-+ * With the new code, the timer that caused the callback gets passed
-+ * to the timer callback function. The 'data' field has been removed.

-    RHBZ1566422 - fix spurious Build-id mismatch when probing reinserted kernel module
-    
-    Code for newer kernels did not clear the address of the notes-section
-    when a probed module was unloaded. This caused spurious Build-id mismatch
-    when the module was reinserted as new addresses are not computed for
-    dynamically loaded modules (see also: PR23068) and the Build-id check
-    was trying to read the notes section at the no-longer-valid old address.
-    
-    * runtime/sym.c (_stp_module_notifier): clear addresses on
-    MODULE_STATE_GOING in newer kernels (>=3.10) too.
-    * runtime/transport/symbols.c (_stp_kmodule_update_address): fix logic
-    error and clear notes section addr when reloc=NULL (aka. 'all').

-Subject: [PATCH] linux runtime: Add support for new kernel unwind fallback.
-
-In newer kernels dump_trace got replaced by a new unwind infrastructure.
-Add a new autoconf-unwind-stack-trace.c to detect whether we can use it.
-Extend the runtime/stack.c _stp_stack_print_fallback with a new pt_regs*
-argument. Update all callers and add dbug_unwind output to show which
-fallback unwinder we are selecting (or if we are just giving up).
-Rename the struct unwind_state in unwind.c and unwind.h to uw_state
-because the old name now conflicts with the one used in the kernel.

-    Make kernel DWARF unwinder work with ksalr.
-    
-    The .debug_frame loaded from disk is already relocated against the
-    expected load offset of the kernel, but the actual static (load)
-    address might be different (with kaslr). So adjust the startLoc
-    for that difference when reading any address from the unwind table.
