| 1 | When I compiled uml on x86_64, I got this warning: |
| 2 | |
| 3 | MODPOST vmlinux.o |
| 4 | WARNING: vmlinux.o (.__syscall_stub.2): unexpected non-allocatable section. |
| 5 | Did you forget to use "ax"/"aw" in a .S file? |
| 6 | Note that for example <linux/init.h> contains |
| 7 | section definitions for use in .S files. |
| 8 | |
| 9 | Because modpost checks for missing SHF_ALLOC section flag. So just |
| 10 | add it. :) |
