New arch support: RISC-V 32-bit and 64-bit, tested on v4.15+ kernels (i.e., since the first Linux version supporting RISC-V).
Improvements:
- Improve dummy syscall implementation detection: try to first match known "ni_syscall" code.
- Improve error messages and debug/info logs, pretty printing command-line arguments and executed commands instead of dumping their tuple/list representation.
- mips: implement simple arch-specific dummy syscall detection.
- arm64: remove "arm64_" arch-specific prefix from syscall names.
Bug fixes:
- mips: new dummy syscall detection now correctly identifies some dummy syscalls that were previously missed (notably
cachestat).
Internal changes:
- Archs can now specify multiple kernel Makefile config targets to run one after the other as a "base" config.
