Merge tag 'xtensa-20181228' of git://github.com/jcmvbkbc/linux-xtensa

Pull Xtensa updates from Max Filippov:

 - switch to generated syscall table

 - switch ptrace to regsets, use regsets for core dumps

 - complete tracehook implementation

 - add syscall tracepoints support

 - add jumplabels support

 - add memtest support

 - drop unused/duplicated code from entry.S, ptrace.c, coprocessor.S,
   elf.h and syscall.h

 - clean up warnings caused by WSR/RSR macros

 - clean up DTC warnings about SPI controller node names in xtfpga.dtsi

 - simplify coprocessor.S

 - get rid of explicit 'l32r' instruction usage in assembly
