1757 64-bit addressing which in turn makes the PTEs 64-bit in size.

1773 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which

1775 unexpectedly. For more information please refer to the gas
1776 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1777
1778 Loongson 2F03 and later have fixed these issues and no workarounds
1779 are needed. The workarounds have no significant side effect on them
1780 but may decrease the performance of the system so this option should
1781 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1782 systems.

2803 running a MIPS32 system and know that none of your userland binaries
