Merge tag 'kgdb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux
Pull kgdb updates from Daniel Thompson: "By far the biggest change in this cycle are the changes that allow much earlier debug of systems that are hooked up via UART by taking advantage of the earlycon framework to implement the kgdb I/O hooks before handing over to the regular polling I/O drivers once they are available. When discussing Doug's work we also found and fixed an broken raw_smp_processor_id() sequence in in_dbg_master(). Also included are a collection of much smaller fixes and tweaks: a couple of tweaks to ged rid of doc gen or coccicheck warnings, future proof some internal calculations that made implicit power-of-2 assumptions and eliminate some rather weird handling of magic environment variables in kdb" * tag 'kgdb-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux: kdb: Remove the misfeature 'KDBFLAGS' kdb: Cleanup math with KDB_CMD_HISTORY_COUNT serial: amba-pl011: Support kgdboc_earlycon serial: 8250_early: Support kgdboc_earlycon serial: qcom_geni_serial: Support kgdboc_earlycon serial: kgdboc: Allow earlycon initialization to be deferred Documentation: kgdboc: Document new kgdboc_earlycon parameter kgdb: Don't call the deinit under spinlock kgdboc: Disable all the early code when kgdboc is a module kgdboc: Add kgdboc_earlycon to support early kgdb using boot consoles kgdboc: Remove useless #ifdef CONFIG_KGDB_SERIAL_CONSOLE in kgdboc kgdb: Prevent infinite recursive entries to the debugger kgdb: Delay "kgdbwait" to dbg_late_init() by default kgdboc: Use a platform device to handle tty drivers showing up late Revert "kgdboc: disable the console lock when in kgdb" kgdb: Disable WARN_CONSOLE_UNLOCKED for all kgdb kgdb: Return true in kgdb_nmi_poll_knock() kgdb: Drop malformed kernel doc comment kgdb: Fix spurious true from in_dbg_master()
