Hi Palmer:
The "kgdb: enable arch to support XML packet support." patch seems to
be missing in this pull request. By the way, I recently sent the v5
KGDB patch set to fix some compile warning reported by Kbuild system
and select CONFIG ARCH_OPTIONAL_KERNEL_RWX in Kconfig to enable KGDB
to insert software breakpoints. If the v5 KGDB patch set is OK for
you, could you replace it with the v5 KGDB patch set?
Thank you.
