linux-next: build failure after merge of the vfs tree

[Stephen Rothwell]

Hi all,

After merging the vfs tree, today's linux-next build (x86_64 allnoconfig)
failed like this:

arch/x86/include/asm/barrier.h: Assembler messages:
arch/x86/include/asm/barrier.h:41: Error: operand type mismatch for `cmp'
arch/x86/include/asm/barrier.h:41: Error: operand type mismatch for `cmp'

and many more ...

Caused by commit

  e33ea6e5ba6a ("x86/uaccess: Use pointer masking to limit uaccess speculation")

I am not exactly sure why (but reverting it fixes the build).

I have reverted that commit for today.
