1805 64-bit addressing which in turn makes the PTEs 64-bit in size.

1823 unexpectedly. For more information please refer to the gas
1824 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1825
1826 Loongson 2F03 and later have fixed these issues and no workarounds
1827 are needed. The workarounds have no significant side effect on them
1828 but may decrease the performance of the system so this option should
1829 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1830 systems.

2143 memory. Default is 40 bits or less, depending on the CPU.
2144 For page sizes 16k and above, this option results in a small
