    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
