[dama219]

Hi,
My PC env is Ubuntu 18.04 and the pahole version is v1.21.
The linux kernel source code version is 5.10.120. When I compiled an kernel image for ARM64 , I found that there is no percpu DATASEC in the btf information of vmlinux.

I debugged the source code of pahole and made the following modifications：

After applying the above modification, vmlinux has percpu DATASEC.
