[fix targetting -stable only, no upstream commit required]
In the bad old days, our compat syscall table was a linear array
defined in assembly code using a series of .quad directives generated
from a preprocessed header file.
When I added compat support for memfd_create and getrandom in commit
a97a42c47608 ("arm64: compat: wire up memfd_create and getrandom
syscalls for aarch32"), I forgot to pad the gap where seccomp was due
to go, and so the new syscalls actually ended up being off-by-one in the
table for v3.17 and v3.18 (in 3.19 seccomp was added and in v4.0 we
moved the table construction into C).
This patch is intended for -stable trees based on v3.17 or v3.18.
