This is a note to let you know that I have just added a patch titled powerpc: Fix dedotify for binutils >= 2.26 to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt26. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ---8<------------------------------------------------------------ From d7fc59480cc00ba316e76ed692b89b0891322e48 Mon Sep 17 00:00:00 2001 From: Andreas Schwab <schwab@linux-m68k.org> Date: Fri, 5 Feb 2016 19:50:03 +0100 Subject: powerpc: Fix dedotify for binutils >= 2.26 commit f15838e9cac8f78f0cc506529bb9d3b9fa589c1f upstream. Since binutils 2.26 BFD is doing suffix merging on STRTAB sections. But dedotify modifies the symbol names in place, which can also modify unrelated symbols with a name that matches a suffix of a dotted name. To remove the leading dot of a symbol name we can just increment the pointer into the STRTAB section instead. Backport to all stables to avoid breakage when people update their binutils - mpe.
