Hi all,
Today's linux-next build (x86_64 allmodconfig) failed like this:
x86_64-unknown-linux-gnu-objcopy: unrecognized option `--globalize-symbol'
Introduced by commit 46483cdbb5dc06d84d9572bac1b90f6744c7fc95 ("ftrace:
create __mcount_loc section").
The currently documented minimum requirements for binutils is 2.12.
$ x86_64-unknown-linux-gnu-objcopy --version
GNU objcopy 2.16.1
For now I have reverted commit c2ffd56692cc4b762c175fad69b70a4ec0dfca3f
("ftrace: enable using mcount recording on x86") since that is the least
intrusive thing to do and the above change depends on
CONFIG_FTRACE_MCOUNT_RECORD.

Cheers,

OK, I can test to see if objdump is >= version 2.18 and if it is not, I can simply not mark those functions. The current mcount for MCOUNT_RECORD is simply a "ret".

If the kernel is being compiled on a system with a lower version of objcopy, then we can not use the globalize / localize trick to link to symbols pointing to local functions. This patch tests the version of objcopy and will only use the trick if the version is greater than or equal to 2.17. Otherwise, if an object has only local functions within a section, it will give a nice warning and recommend the user to upgrade their objcopy. Leaving the symbols unrecorded is not that big of a deal, since the mcount record method changes the actual mcount code to be a simple "ret" without recording registers or anything.

Hmm, Well we don't need the warning, although it would be nice to give. There seems to be a lot of hacking to get a warning for this.
