1325 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1326 require workarounds. Without workarounds the system may hang
1327 unexpectedly. For more information please refer to the gas
1328 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1330 Loongson 2F03 and later have fixed these issues and no workarounds
1331 are needed. The workarounds have no significant side effect on them
1332 but may decrease the performance of the system so this option should
1333 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1334 systems.

2046 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
2047 previous 64-bit processors which only supported 40 bit / 1TB. If you

2052 config KEXEC

2055 help
2056 kexec is a system call that implements the ability to shutdown your
2057 current kernel, and to start another kernel. It is like a reboot
2058 but it is independent of the system firmware. And like a reboot
2059 you can start any kernel with it, not just Linux.
2061 The name comes from the similarity to the exec system call.
2063 It is an ongoing process to be certain the hardware in a machine
2064 is properly shutdown, so do not be surprised if this code does not
2065 initially work for you. It may help to enable device hotplugging
2066 support. As of this writing the exact hardware interface is
2067 strongly in flux, so no good recommendation can be made.

2073 help
2074 This kernel feature is useful for number crunching applications
2075 that may need to compute untrusted bytecode during their
2076 execution. By using pipes or other transports made available to
2077 the process as file descriptors supporting the read/write
2078 syscalls, it's possible to isolate those applications in
2079 their own address space using seccomp. Once seccomp is
2080 enabled via /proc/<pid>/seccomp, it cannot be disabled
2081 and the task is only allowed to execute a few safe syscalls
2082 defined by each seccomp mode.
2084 If unsure, say Y. Only embedded should say N here.

2136 The Extended Industry Standard Architecture (EISA) bus was

2139 The EISA bus provided some of the features of the IBM MicroChannel
2140 bus while maintaining backward compatibility with cards made for
2141 the older ISA bus. The EISA bus saw limited use between 1988 and
2142 1995 when it was made obsolete by the PCI bus.
