Hi Michael,

After merging the vhost tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from arch/powerpc/include/asm/uaccess.h:12:0,
                 from arch/powerpc/lib/checksum_wrappers_64.c:24:
include/asm-generic/uaccess.h: In function 'might_fault':
include/asm-generic/uaccess.h:36:2: error: implicit declaration of function 'segment_eq' [-Werror=implicit-function-declaration]
  if (_might_fault())
  ^
include/asm-generic/uaccess.h:36:2: error: implicit declaration of function 'get_fs' [-Werror=implicit-function-declaration]
include/asm-generic/uaccess.h:29:47: error: 'KERNEL_DS' undeclared (first use in this function)
 #define _might_fault() (!segment_eq(get_fs(), KERNEL_DS) && !in_atomic())
                                               ^
include/asm-generic/uaccess.h:36:6: note: in expansion of macro '_might_fault'
  if (_might_fault())
      ^

and many, many more.

Caused by commit d198a8acf543 ("kernel: might_fault does not imply
might_sleep").

I have used the version of the vhost tree from next-20130521 for today.

It was unexpected that such patches would turn up in the "vhost" tree ...
