#     Merge tag 'trace-v5.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing and bootconfig updates:
#      "Fixes and changes to bootconfig before it goes live in a release.
#     
#       Change in API of bootconfig (before it comes live in a release):
#       - Have a magic value "BOOTCONFIG" in initrd to know a bootconfig
#         exists
#       - Set CONFIG_BOOT_CONFIG to 'n' by default
#       - Show error if "bootconfig" on cmdline but not compiled in
#       - Prevent redefining the same value
#       - Have a way to append values
#       - Added a SELECT BLK_DEV_INITRD to fix a build failure
#     
#       Synthetic event fixes:
#       - Switch to raw_smp_processor_id() for recording CPU value in preempt
#         section. (No care for what the value actually is)
#       - Fix samples always recording u64 values
#       - Fix endianess
#       - Check number of values matches number of fields
#       - Fix a printing bug
#     
#       Fix of trace_printk() breaking postponed start up tests
#     
#       Make a function static that is only used in a single file"
#
