#     Merge tag 'mips_fixes_5.0_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
#     
#     Pull MIPS fixes from Paul Burton:
#     
#      - Fix IPI handling for Lantiq SoCs, which was broken by changes made
#        back in v4.12.
#     
#      - Enable OF/DT serial support in ath79_defconfig to give us working
#        serial by default.
#     
#      - Fix 64b builds for the Jazz platform.
#     
#      - Set up a struct device for the BCM47xx SoC to allow BCM47xx drivers
#        to perform DMA again following the major DMA mapping changes made in
#        v4.19.
#     
#      - Disable MSI on Cavium Octeon systems when the pcie_disable command
#        line parameter introduced in v3.3 is used, in order to avoid
#        inadvetently accessing PCIe controller registers despite the command
#        line.
#     
#      - Fix a build failure for Cavium Octeon kernels with kexec enabled,
#        introduced in v4.20.
#     
#      - Fix a regression in the behaviour of semctl/shmctl/msgctl IPC
#        syscalls for kernels including n32 support but not o32 support caused
#        by some cleanup in v3.19.
