1828 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1830 Loongson 2F03 and later have fixed these issues and no workarounds
1831 are needed. The workarounds have no significant side effect on them
1832 but may decrease the performance of the system so this option should
1833 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1834 systems.

2155 memory. Default is 40 bits or less, depending on the CPU.
2156 For page sizes 16k and above, this option results in a small

2158 level of page tables is added which imposes both a memory
