* 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus: MIPS: Octeon: Place cnmips_cu2_setup in __init memory. MIPS: Don't place cu2 notifiers in __cpuinitdata MIPS: Calculate VMLINUZ_LOAD_ADDRESS based on the length of vmlinux.bin MIPS: Alchemy: Resolve prom section mismatches MIPS: Fix syscall 64 bit number comments. MIPS: Hookup fanotify_init, fanotify_mark, and prlimit64 syscalls. MIPS: TX49xx: Rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN MIPS: N32: Fix getdents64 syscall for n32 MIPS: Remove pr_<level> uses of KERN_<level> MIPS: PNX8550: Sort out machine halt, restart and powerdown functions. MIPS: GIC: Remove dependencies from Malta files. MIPS: Kconfig: Fix and clarify kconfig help text for VSMP and SMTC. MIPS: DMA: Fix computation of DMA flags from device's coherent_dma_mask. MIPS: Audit: Fix hang in entry.S. MIPS: Document why RELOC_HIDE is there. MIPS: Octeon: Determine if helper needs to be built MIPS: Use generic atomic64 for 32-bit kernels MIPS: RM7000: Symbol should be static MIPS: kspd: Adjust confusing if indentation MIPS: Fix a typo.
