tools/perf: Add basic support for LoongArch (2023-05-01 17:19:59 +0800)
----------------------------------------------------------------
LoongArch changes for v6.4
1, Better backtraces for humanization;
2, Relay BCE exceptions to userland as SIGSEGV;
3, Provide kernel fpu functions;
4, Optimize memory ops (memset/memcpy/memmove);
5, Optimize checksum and crc32(c) calculation;
6, Add ARCH_HAS_FORTIFY_SOURCE selection;
7, Add function error injection support;
8, Add ftrace with direct call support;
9, Add basic perf tools support.
Note: There are merge conflicts in these files but can be simply fixed
by adjusting context around "static struct ftrace_ops direct":
samples/ftrace/ftrace-direct-modify.c
samples/ftrace/ftrace-direct-too.c
samples/ftrace/ftrace-direct.c
