1837 Loongson 2F03 and later have fixed these issues and no workarounds
1838 are needed. The workarounds have no significant side effect on them

2230 a value of 11 means that the largest free memory block is 2^10 pages.

2969 Beware that there is very little in terms of protection against
2970 this option being confused by leftover garbage in memory that might
2971 look like a DTB header after a reboot if no actual DTB is appended
2972 to vmlinux.bin. Do not leave this option active in a production kernel

3084 bus while maintaining backward compatibility with cards made for
