#     Merge tag 'kgdb-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux
#     
#     Pull kgdb updates from Daniel Thompson:
#      "Another fairly small set of changes of changes this cycle. The most
#       significant functional change is a fix to better manage the flags when
#       allocating memory.
#     
#       Additionally there is the removal of some unused code (which is
#       slightly more dramatic than it sounds given it means there are now no
#       tasklets in kgdb) together with a tidy up of the debug prints and some
#       spelling corrections for the documentation"
#     
#     * tag 'kgdb-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
#       kgdb: Remove kgdb_schedule_breakpoint()
#       kdb: Make memory allocations more robust
#       kdb: kdb_support: Fix debugging information problem
#       kernel: debug: fix typo issue
#       kgdb: rectify kernel-doc for kgdb_unregister_io_module()
