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