After commit 9854e7ad35fe ("perf arm64: Simplify mksyscalltbl"), in the generated syscall table file syscalls.c, there exist some __NR3264_ prefixed syscall numbers such as [__NR3264_ftruncate], it looks like not so good, just do some small filter operations to handle __NR3264_ prefixed syscall number as a digital number.
Without this patch:
[__NR3264_ftruncate] = "ftruncate",
With this patch:
[46] = "ftruncate",
