commit 7bbcbd3d1c upstream.
The recent cpu_entry_area changes fail to compile on 32-bit when BIGSMP=y
and NR_CPUS=512, because the fixmap area becomes too big.
Limit the number of CPUs with BIGSMP to 64, which is already way to big for
32-bit, but it's at least a working limitation.
We performed a quick survey of 32-bit-only machines that might be affected
by this change negatively, but found none.
