linux-next: build failure after merge of the akpm-current tree

[Stephen Rothwell]

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

sound/pcmcia/pdaudiocf/pdaudiocf.o: warning: objtool: .text: unexpected end of section
arch/x86/ras/mce_amd_inj.o: warning: objtool: inj_readme_read() falls through to next function extcpu_fops_open()
sound/sound_core.o: warning: objtool: register_sound_special_device() falls through to next function register_sound_special()

and many more like those. Also:

Caused by commit

  088a5ecf7581 ("include/linux/string.h: add the option of fortified string.h functions")

We really need to fix all the known problems it detects *before*
merging this commit ...

I have reverted it for today.
