1772 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1773 benefit is to increase physical addressing equal to or greater
1774 than 40 bits. Note that this has the side effect of turning on
1775 64-bit addressing which in turn makes the PTEs 64-bit in size.

1791 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which

1793 unexpectedly. For more information please refer to the gas
1794 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1795
1796 Loongson 2F03 and later have fixed these issues and no workarounds
1797 are needed. The workarounds have no significant side effect on them
1798 but may decrease the performance of the system so this option should
1799 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1800 systems.

2936 Beware that there is very little in terms of protection against
2937 this option being confused by leftover garbage in memory that might
2938 look like a DTB header after a reboot if no actual DTB is appended

3051 The EISA bus provided some of the features of the IBM MicroChannel
3052 bus while maintaining backward compatibility with cards made for
3053 the older ISA bus. The EISA bus saw limited use between 1988 and
3054 1995 when it was made obsolete by the PCI bus.
