A few minor MIPS fixes:
- Provide struct pt_regs * from get_irq_regs() to kgdb_nmicallback() when handling an IPI triggered by kgdb_roundup_cpus(), matching the behavior of other architectures & resolving kgdb issues for SMP systems. - Defer a pointer dereference until after a NULL check in the irq_shutdown callback for SGI IP27 HUB interrupts. - A defconfig update for the MSCC Ocelot to enable some necessary drivers. -----BEGIN PGP SIGNATURE----- iIsEABYIADMWIQRgLjeFAZEXQzy86/s+p5+stXUA3QUCXK0n2BUccGF1bC5idXJ0 b25AbWlwcy5jb20ACgkQPqefrLV1AN3rCAD/QLvPpE1YhmJ4Gd6MOEM2HHC15HHR U0ROHAEO3+ZwZf4A/3aBKZMtEKrLJnxG+MEqhuDMtIu//J6kGSpOpMZ5y7YJ =zRUT -----END PGP SIGNATURE----- Merge tag 'mips_fixes_5.1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux Pull MIPS fixes from Paul Burton: "A few minor MIPS fixes: - Provide struct pt_regs * from get_irq_regs() to kgdb_nmicallback() when handling an IPI triggered by kgdb_roundup_cpus(), matching the behavior of other architectures & resolving kgdb issues for SMP systems. - Defer a pointer dereference until after a NULL check in the irq_shutdown callback for SGI IP27 HUB interrupts. - A defconfig update for the MSCC Ocelot to enable some necessary drivers" * tag 'mips_fixes_5.1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: generic: Add switchdev, pinctrl and fit to ocelot_defconfig MIPS: SGI-IP27: Fix use of unchecked pointer in shutdown_bridge_irq MIPS: KGDB: fix kgdb support for SMP platforms.
