Subject: [PATCH 3/3] perf tools: Generate mips syscalls_n64.c syscall table
Grab a copy of arch/mips/kernel/syscalls/syscall_n64.tbl and use it to
generate tools/perf/arch/mips/include/generated/asm/syscalls_n64.c file,
this is similar with commit 1b700c997500 ("perf tools: Build syscall table
.c header from kernel's syscall_64.tbl")
