Build failures in v3.10-stable-queue, v3.14-stable-queue

[Guenter Roeck <linux@roeck-us.net>]

arm64 (v3.10):

arch/arm64/mm/mmu.c: In function ‘paging_init’:
arch/arm64/mm/mmu.c:352:11: error: macro "dsb" passed 1 arguments, but takes just 0
   dsb(ishst);

Culprit is 'arm64: mm: ensure that the zero page is visible to the page table walker'.
dsb() doesn't have an argument in v3.10. Copying Will Deacon for advice.

arm64, i386, m68k, mips, powerpc, sparc, xtensa (v3.14):

drivers/net/vxlan.c: In function ‘vxlan_newlink’:
include/net/vxlan.h:30:28: error: ‘VXLAN_F_UDP_ZERO_CSUM6_RX’ undeclared (first use in this function)
  #define VXLAN_F_RCV_FLAGS  VXLAN_F_UDP_ZERO_CSUM6_RX

Culprit is 'vxlan: fix test which detect duplicate vxlan iface'. VXLAN_F_UDP_ZERO_CSUM6_RX
does not exist in v3.14. Copying Nicolas Dichtel for advice.

mn10300 (v3.10, v3.14):

kernel/uid16.c:19:1: error: unknown type name 'old_uid_t'
kernel/uid16.c:19:1: error: unknown type name 'old_gid_t'
ipc/util.c:609:2: error: 'old_uid_t' undeclared

and other similar errors. Requires c86576ea114a ("mn10300: Select CONFIG_HAVE_UID16
to fix build failure"). Results in minor easy to resolve conflict in v3.10.y (I didn't
check v3.14.y). Let me know if you need a backport.

---
openrisc (v3.10, v3.14):

fs/stat.c:230:2: error: 'old_uid_t' undeclared

and many others.

Requires 04ea1e91f856 ("openrisc: fix CONFIG_UID16 setting").
