Correction: I thought -Wl,--icf=safe was the cause of the trouble, but I was
wrong. I falsely thought so because I failed to make clean before recompiling
the kernel. After a make clean I removed all custom linker flags from the
Makefile and recompiled with Gold and still got the error. I then ran another
make clean and changed my default linker to ld.bfd and recompiled and the error
disappeared.

 Bug #: 13857
   Summary: WARNING: Absolute relocations present compiling
Linux kernel using -Wl,--icf=safe
   Product: binutils
   Version: 2.22
Status: NEW
  Severity: normal
  Priority: P2
 Component: gold
AssignedTo: i...@airs.com
ReportedBy: doctorwho...@gmail.com
CC: ccout...@google.com
Classification: Unclassified


I compiled Linux kernel 3.2.9 with Gentoo and CK patches and used the Gold
linker 1.11 from binutils 2.22. I added additional linker flags to the Makefile
including -Wl,--icf=safe. After compiling, I saw the error message:

I removed -Wl,--icf=safe and recompiled and did not receive the error again.
