83 The Extended Industry Standard Architecture (EISA) bus was
84 developed as an open alternative to the IBM MicroChannel bus.
85
86 The EISA bus provided some of the features of the IBM MicroChannel
87 bus while maintaining backward compatibility with cards made for
88 the older ISA bus. The EISA bus saw limited use between 1988 and
89 1995 when it was made obsolete by the PCI bus.

1108 be incorrectly associated with a different cache line. This false

1217 Under some condition the effect of cache sync operation on

1219 This means that the store buffer is always asked to drain and

1221 is to replace the normal offset of cache sync operation (0x730)
1222 by another offset targeting an unmapped PL310 register 0x740.

1446 help
1447 Various binutils versions can resolve Thumb-2 branches to
1448 locally-defined, preemptible global symbols as short-range "b.n"
1449 branch instructions.
1450
1451 This is a problem, because there's no guarantee the final
1452 destination of the symbol, or any candidate locations for a
1453 trampoline, are within range of the branch. For this reason, the
1454 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1455 relocation in modules at all, and it makes little sense to add
1456 support.
1457
1458 The symptom is that the kernel fails with an "unsupported
1459 relocation" error when loading some modules.
1460
1461 Until fixed tools are available, passing
1462 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1463 code which hits this problem, at the cost of a bit of extra runtime
1464 stack usage in some cases.
1465
1466 The problem is described in more detail at:
1467 https://bugs.launchpad.net/binutils-linaro/+bug/725126

1469 Only Thumb-2 kernels are affected.

1930 Say Y to include the NWFPE floating point emulator in the kernel.
1931 This is necessary to run most binaries. Linux does not currently
1932 support floating point hardware so you need to say Y here even if
1933 your machine has an FPA or floating point co-processor podule.

1936 early in the bootup.

1944 Note that gcc does not generate 80-bit operations by default,
1945 so in most cases this option only enlarges the size of the
1946 floating point emulator without any good reason.

1954 Say Y here to include the FAST floating point emulator in the kernel.
1955 This is an experimental much faster emulator which now also has full
1956 precision for the mantissa. It does not support any exceptions.
1957 It is very simple, and approximately 3-6 times faster than NWFPE.
1958
1959 It should be sufficient for most programs. It may be not suitable
1960 for scientific calculations, but you have to check this for yourself.
1961 If you do not feel you need a faster FP emulation you should better
1962 choose NWFPE.
