#     Merge tag 'mips_fixes_5.1_1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
#     
#     Pull MIPS fixes from Paul Burton:
#      "A small batch of MIPS fixes for 5.1:
#     
#        - An interrupt masking fix for Loongson-based Lemote 2F systems
#          (fixing a regression from v3.19)
#     
#        - A relocation fix for configurations in which the devicetree is
#          stored in an ELF section (fixing a regression from v4.7)
#     
#        - Fix jump labels for MIPSr6 kernels where they previously could
#          inadvertently place a control transfer instruction in a forbidden
#          slot & take unexpected exceptions (fixing MIPSr6 support added in
#          v4.0)
#     
#        - Extend an existing USB power workaround for the Netgear WNDR3400 to
#          v2 boards in addition to the v3 ones that already used it
#     
#        - Remove the custom MIPS32 definition of __kernel_fsid_t to make it
#          consistent with MIPS64 & every other architecture, in particular
#          resolving issues for code which tries to print the val field whose
#          type previously differed (though had identical memory layout)"
#
