Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This is an unusually large pull request for MIPS - in parts because
lots of patches missed the 3.18 deadline but primarily because some
folks opened the flood gates.
- Retire the MIPS-specific phys_t with the generic phys_addr_t.
- Improvments for the backtrace code used by oprofile.
- Better backtraces on SMP systems.
- Cleanups for the Octeon platform code.
- Cleanups and fixes for the Loongson platform code.
- Cleanups and fixes to the firmware library.
- Switch ATH79 platform to use the firmware library.
- Grand overhault to the SEAD3 and Malta interrupt code.
- Move the GIC interrupt code to drivers/irqchip
- Lots of GIC cleanups and updates to the GIC code to use modern IRQ
infrastructures and features of the kernel.
- OF documentation updates for the GIC bindings
- Move GIC clocksource driver to drivers/clocksource
- Merge GIC clocksource driver with clockevent driver.
- Further updates to bring the GIC clocksource driver up to date.
- R3000 TLB code cleanups
- Improvments to the Loongson 3 platform code.
- Convert pr_warning to pr_warn.
- Merge a bunch of small lantiq and ralink fixes that have been
staged/lingering inside the openwrt tree for a while.
- Update archhelp for IP22/IP32
- Fix a number of issues for Loongson 1B.
- New clocksource and clockevent driver for Loongson 1B.
- Further work on clk handling for Loongson 1B.
- Platform work for Broadcom BMIPS.
- Error handling cleanups for TurboChannel.
- Fixes and optimization to the microMIPS support.
- Option to disable the FTLB.
- Dump more relevant information on machine check exception
- Change binfmt to allow arch to examine PT_*PROC headers
- Support for new style FPU register model in O32
- VDSO randomization.
- BCM47xx cleanups
- BCM47xx reimplement the way the kernel accesses NVRAM information.
- Random cleanups
- Add support for ATH25 platforms
- Remove pointless locking code in some PCI platforms.
- Some improvments to EVA support
- Minor Alchemy cleanup"
