Merge tag 'csky-for-linus-4.21' of git://github.com/c-sky/csky-linux
Pull arch/csky updates from Guo Ren: "Here are three main features (cpu_hotplug, basic ftrace, basic perf) and some bugfixes: Features: - Add CPU-hotplug support for SMP - Add ftrace with function trace and function graph trace - Add Perf support - Add EM_CSKY_OLD 39 - optimize kernel panic print. - remove syscall_exit_work Bugfixes: - fix abiv2 mmap(... O_SYNC) failure - fix gdb coredump error - remove vdsp implement for kernel - fix qemu failure to bootup sometimes - fix ftrace call-graph panic - fix device tree node reference leak - remove meaningless header-y - fix save hi,lo,dspcr regs in switch_stack - remove unused members in processor.h" * tag 'csky-for-linus-4.21' of git://github.com/c-sky/csky-linux: csky: Add perf support for C-SKY csky: Add EM_CSKY_OLD 39 clocksource/drivers/c-sky: fixup ftrace call-graph panic csky: ftrace call graph supported. csky: basic ftrace supported csky: remove unused members in processor.h csky: optimize kernel panic print. csky: stacktrace supported. csky: CPU-hotplug supported for SMP clocksource/drivers/c-sky: fixup qemu fail to bootup sometimes. csky: fixup save hi,lo,dspcr regs in switch_stack. csky: remove syscall_exit_work csky: fixup remove vdsp implement for kernel. csky: bugfix gdb coredump error. csky: fixup abiv2 mmap(...
