1358 Loongson 2F03 and later have fixed these issues and no workarounds

1925 a system with only one CPU, like most personal computers, say N. If
1926 you have a system with more than one CPU, say Y.
1927
1928 If you say N here, the kernel will run on single and multiprocessor
1929 machines, but will use only one CPU of a multiprocessor machine. If
1930 you say Y here, the kernel will run on many, but not all,

1932 will run faster if you say N here.
