The quilt patch titled
     Subject: kselftests: mm: fix wrong __NR_userfaultfd value
has been removed from the -mm tree.  Its filename was

__NR_userfaultfd (__X32_SYSCALL_BIT + 323)
arch/arm/include/generated/uapi/asm/unistd-eabi.h:347:#define
__NR_userfaultfd (__NR_SYSCALL_BASE + 388)
arch/arm/include/generated/uapi/asm/unistd-oabi.h:359:#define
__NR_userfaultfd (__NR_SYSCALL_BASE + 388)
include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultfd 282

The number is dependent on the architecture. The above data shows that:
x86	374
x86_64	323

The value of __NR_userfaultfd was changed to 282 when asm-generic/unistd.h
was included.  It makes the test to fail every time as the correct number
of this syscall on x86_64 is 323.  Fix the header to asm/unistd.h.
