bpf

perform a command on an extended BPF map or program

sys_bpf(int cmd, union bpf_attr *attr, unsigned int size, struct bpf_common_attr *attr_common, unsigned int size_common)

register	value
`x8`	280, the syscall number
`x0`	int cmd
`x1`	union bpf_attr *attr
`x2`	unsigned int size
`x3`	struct bpf_common_attr *attr_common
`x4`	unsigned int size_common
`x0`	the return value

Then run svc #0 to enter the kernel.

Same syscall on other architectures
