Subject: linux-next: build failure after merge of the blackfin tree

Hi Mike,

After merging the blackfin tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

kernel/trace/trace_syscalls.c:402: error: redefinition of 'arch_syscall_addr'
kernel/trace/trace_syscalls.c:397: note: previous definition of 'arch_syscall_addr' was here

Caused by commit d156d1881ea54ec609d92388601661c2679439bb ("ftrace: unify
arch_syscall_addr() implementations") from the blackfin tree interacting
with commit e7b8e675d9c71b868b66f62f725a948047514719 ("tracing: Unify
arch_syscall_addr() implementations") from Linus' tree.

These are slightly different versions of the same patch. but merging with the blackfin tree managed to add a second copy of the above function.  I have applied the following patch for today.
