4.4-stable review patch.  If anyone has any objections, please let me know.


From: Arnd Bergmann <a...@arndb.de>

commit 553bbc11aa6c1f9e0f529a06aeeca15fbe4a3985 upstream.

The latest binutils are warning about a .fill directive with an explicit
value in a .bss section:

  arch/x86/kernel/head_32.S: Assembler messages:
  arch/x86/kernel/head_32.S:677: Warning: ignoring fill value in section 
  arch/x86/kernel/head_32.S:679: Warning: ignoring fill value in section 

This comes from the 'ENTRY()' macro padding the space between the symbols
with 'nop' via:

  .align 4,0x90

Open-coding the .globl directive without the padding avoids that warning,
as all the symbols are already page aligned.
