Subject: linux-next: manual merge of the signal tree with the modules tree

Hi Al,

Today's linux-next merge of the signal tree got a conflict in
include/asm-generic/unistd.h between commit 837718bfd28b
("CONFIG_SYMBOL_PREFIX: cleanup") from the modules tree and commit
e1b5bb6d1236 ("consolidate cond_syscall and SYSCALL_ALIAS declarations")
from the signal tree.

The latter moved the cond_syscall stuff to linkage.h, so I applied the
following patch as a merge fixup and can carry the fix as necessary (no
action is required).  I am not sure if this is completely correct or all
that is needed.
