Merge tag 'mips_fixes_5.1_1' into mips-next

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).

Merged into mips-next to gain the MIPSr6 jump label fix before enabling
jump labels by default for generic kernel builds.
