Merge tag 'mips_fixes_4.16_2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips
Pull MIPS fixes from James Hogan: "A few fixes for outstanding MIPS issues: - an __init section mismatch warning when brcmstb_pm is enabled - a regression handling multiple mem=X@Y arguments (4.11) - a USB Kconfig select warning, and related sparc cleanup (4.16)" * tag 'mips_fixes_4.16_2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips: sparc,leon: Select USB_UHCI_BIG_ENDIAN_{MMIO,DESC} usb: Move USB_UHCI_BIG_ENDIAN_* out of USB_SUPPORT MIPS: Fix incorrect mem=X@Y handling MIPS: BMIPS: Fix section mismatch warning
