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 * tag 'xtensa-20181228' of git://github.com/jcmvbkbc/linux-xtensa: (25 commits) xtensa: implement jump_label support xtensa: implement syscall tracepoints xtensa: implement tracehook functions and enable HAVE_ARCH_TRACEHOOK xtensa: enable CORE_DUMP_USE_REGSET xtensa: implement TIE regset xtensa: implement task_user_regset_view xtensa: call do_syscall_trace_{enter,leave} selectively xtensa: use NO_SYSCALL instead of -1 xtensa: define syscall_get_arch() Move EM_XTENSA to uapi/linux/elf-em.h xtensa: support memtest xtensa: don't use l32r opcode directly xtensa: xtfpga.dtsi: fix dtc warnings about SPI xtensa: don't clear cpenable unconditionally on release xtensa: simplify coprocessor.S xtensa: clean up WSR*/RSR*/get_sr/set_sr xtensa: drop unused declarations from elf.h xtensa: clean up syscall.h xtensa: drop unused coprocessor helper functions xtensa: drop custom PTRACE_{PEEK,POKE}{TEXT,DATA} ...
