Subject: linux-next: build failure after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64_allmodconfig)
failed like this:

/opt/cross/gcc-4.6-nolibc/x86_64-linux/bin/x86_64-linux-objcopy:arch/x86/vdso/vdso-note-x32.o: Invalid bfd target

I appears that we need a 2.22 binutils :-(

$ /opt/cross/gcc-4.6-nolibc/x86_64-linux/bin/x86_64-linux-objcopy --version
GNU objcopy (GNU Binutils) 2.21
$ /opt/cross/gcc-4.6-nolibc/x86_64-linux/bin/x86_64-linux-objcopy --help
	.
	.
/opt/cross/gcc-4.6-nolibc/x86_64-linux/bin/x86_64-linux-objcopy: supported targets: elf64-x86-64 elf32-i386 a.out-i386-linux pei-i386 pei-x86-64 elf64-l1om elf64-little elf64-big elf32-little elf32-big srec symbolsrec verilog tekhex binary ihex

I have applied the following patch for today:
