Pull Xtensa updates from Chris Zankel: "Xtensa improvements for 4.6: - control whether perf IRQ is treated as NMI from Kconfig - implement ioremap for regions outside KIO segment - fix ISS serial port behaviour when EOF is reached - fix preemption in {clear,copy}_user_highpage - fix endianness issues for XTFPGA devices, big-endian cores are now fully functional - clean up debug infrastructure and add support for hardware breakpoints and watchpoints - add processor configurations for Three Core HiFi-2 MX and HiFi3 cpus" * tag 'xtensa-next-20160320' of git://github.com/czankel/xtensa-linux: xtensa: add test_kc705_hifi variant xtensa: add Three Core HiFi-2 MX Variant. xtensa: support hardware breakpoints/watchpoints xtensa: use context structure for debug exceptions xtensa: remove remaining non-functional KGDB bits xtensa: clear all DBREAKC registers on start xtensa: xtfpga: fix earlycon endianness xtensa: xtfpga: fix i2c controller register width and endianness xtensa: xtfpga: fix ethernet controller endianness xtensa: xtfpga: fix serial port register width and endianness xtensa: define CONFIG_CPU_{BIG,LITTLE}_ENDIAN xtensa: fix preemption in {clear,copy}_user_highpage xtensa: ISS: don't hang if stdin EOF is reached xtensa: support ioremap for memory outside KIO region xtensa: use XTENSA_INT_LEVEL macro in asm/timex.h xtensa: make fake NMI configurable
