Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for Linux 4.1. Most
noteworthy:
- Add more Octeon-optimized crypto functions
- Octeon crypto preemption and locking fixes
- Little endian support for Octeon
- Use correct CSR to soft reset Octeons
- Support LEDs on the Octeon-based DSR-1000N
- Fix PCI interrupt mapping for the Octeon-based DSR-1000N
- Mark prom_free_prom_memory() as __init for a number of systems
- Support for Imagination's Pistachio SOC. This includes arch and
CLK bits. I'd like to merge pinctrl bits later
- Improve parallelism of csum_partial for certain pipelines
- Organize DTB files in subdirs like other architectures
- Implement read_sched_clock for all MIPS platforms other than
Octeon
- Massive series of 38 fixes and cleanups for the FPU emulator /
kernel
- Further FPU remulator work to support new features. This sits on a
separate branch which also has been pulled into the 4.1 KVM branch
- Clean up and fixes for the SEAD3 eval board; remove unused file
- Various updates for Netlogic platforms
- A number of small updates for Loongson 3 platforms
- Increase the memory limit for ATH79 platforms to 256MB
- A fair number of fixes and updates for BCM47xx platforms
- Finish the implementation of XPA support
- MIPS FDC support. No, not floppy controller but Fast Debug Channel :)
- Detect the R16000 used in SGI legacy platforms
- Fix Kconfig dependencies for the SSB bus support"
