59 The Extended Industry Standard Architecture (EISA) bus was

62 The EISA bus provided some of the features of the IBM MicroChannel
63 bus while maintaining backward compatibility with cards made for
64 the older ISA bus. The EISA bus saw limited use between 1988 and
65 1995 when it was made obsolete by the PCI bus.

882 This option enables the workaround for the 430973 Cortex-A8
883 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
884 interworking branch is replaced with another code sequence at the

886 to physical address re-mapping, Cortex-A8 does not recover from the

888 executing the new code sequence in the incorrect ARM or Thumb state.
889 The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
890 and also flushes the branch target cache at every context switch.
891 Note that setting specific bits in the ACTLR register may not be
892 available in non-secure mode.

1334 kexec is a system call that implements the ability to shutdown your
1335 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001336 but it is independent of the system firmware. And like a reboot
Richard Purdiec587e4a2007-02-06 21:29:00 +01001337 you can start any kernel with it, not just Linux.
1338
1339 It is an ongoing process to be certain the hardware in a machine
1340 is properly shutdown, so do not be surprised if this code does not
1341 initially work for you. It may help to enable device hotplugging
1342 support.
