From: Arnd Bergmann arnd@arndb.de

[ Upstream commit 0fe2795516b9e1c59b58b02bdf8658698117ec4e ]

Commit b5793b0d92c9 added support for building the nanosleep compat system call on 32-bit architectures, but missed one change in nanosleep_copyout(), which would trigger a BUG() as soon as any architecture is switched over to use it.

Use the proper config symbol to enable the code path.
