Changes since 20140917:
The fsl tree still had its build failure so I used the version from
next-20140917.
The v4l-dvb tree lost its build failure.
The security tree gained a conflict against the file-locks tree.

Bisect points to commit 273299fb6380 ('Merge branch 'x86/seccomp') which
obviously doesn't help much. Suspected culprit is c90f06943e05 ('parisc: Wire up
seccomp, getrandom and memfd_create syscalls') which seems to be missing an
include file.
I've added this patch to my for-next tree:
http://git.kernel.org/cgit/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=0f18557b017b3469e1f8edf5cf34c1cba856fdbe
That doesn't solve the problem for me, most likely because
HAVE_ARCH_SECCOMP_FILTER is not set for parisc in next-20140919.
This is what seccomp.h does with it:
#ifdef CONFIG_HAVE_ARCH_SECCOMP_FILTER
static inline int secure_computing(void) { return 0; }
#else
static inline void secure_computing_strict(int this_syscall) { return; }
#endif
You don't have this flag in your tree. It was introduced in -next with
commit 'seccomp,x86,arm,mips,s390: Remove nr parameter from secure_computing'.
Thanks for the hint!
Since parisc currently only supports the strict mode, I've changed the code
to call secure_computing_strict() instead of secure_computing() with this commit in my for-next tree:
http://git.kernel.org/cgit/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=fe5c873459a973e59854bd235a7e6b3eaa8e5fe0
It now builds cleanly with the next-20140919 tree.
Thanks!
Helge
