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)"
