xtensa: implement jump_label support (2018-12-20 14:44:38 -0800)
----------------------------------------------------------------
Xtensa updates for v4.21:
- 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
