Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus: (150 commits) MIPS: PowerTV: Separate PowerTV USB support from non-USB code MIPS: strip the un-needed sections of vmlinuz MIPS: Clean up the calculation of VMLINUZ_LOAD_ADDRESS MIPS: Clean up arch/mips/boot/compressed/decompress.c MIPS: Clean up arch/mips/boot/compressed/ld.script MIPS: Unify the suffix of compressed vmlinux.bin MIPS: PowerTV: Add Gaia platform definitions. MIPS: BCM47xx: Fix nvram_getenv return value. MIPS: Octeon: Allow more than 3.75GB of memory with PCIe MIPS: Clean up notify_die() usage. MIPS: Remove unused task_struct.trap_no field. Documentation: Mention that KProbes is supported on MIPS SAMPLES: kprobe_example: Make it print something on MIPS. MIPS: kprobe: Add support. MIPS: Add instrunction format for BREAK and SYSCALL MIPS: kprobes: Define regs_return_value() MIPS: Ritually kill stupid printk. MIPS: Octeon: Disallow MSI-X interrupt and fall back to MSI interrupts. MIPS: Octeon: Support 256 MSI on PCIe MIPS: Decode core number for R2 CPUs. ...
