Sorry for replying to old messages but the bug has appeared again in a 
separate case the bug seems to be introduced in
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=d3e52e120b68bf19552743fbc078e0a759f48cb7

The test code is as follows
```
.syntax unified 

.global bug; 

.align 4 

bug: 

         adr     r3, bug 

.size bug, .-bug 

.type bug 2; // This changes offset from 4 to 3 in 
include/linux/linkage.h:ENDPROC
//arm-linux-gnueabi-as  -march=armv7-m -c -o bug.o bug.S && 
arm-linux-gnueabi-objdump --disassemble=bug bug.o
```
Releases >2.37 have this issue and causes some arm platforms in u-boot 
at /arch/arm/lib/relocate.S:81	adr	r3, relocate_code

I'm wondering if there should be a mitigation for this till binutils is 
patched.

Thanks,
Jesse
