Merge tag 'arc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc

Pull ARC updates from Vineet Gupta:

 - ARCv2 support for native 64-bit atomics using LLOCK/SCONDD
   instructions

 - Support for upcoming 3.0 release of HS38 cores

 - Dwarf unwindinder improvements:
   - enable unwinding of hand written assembler code using CFI
     pseudo-ops
   - switch to .eh_frame (as opposed to historic .debug_frame)
   - get rid of a bunch of adhoc band-aids in the process

 - Misc fixes:
   - perf supporting generic cache-references and cache-misses (Alexey)
   - default NODE_SHIFT (Noam Camus)
   - usage of KFLAG instruction to set IE (Yuriy)

 - Platforms:
   - Add "model" property across the DT (Alexey)
   - Enable MODULE_* in defconfigs
