88 The Extended Industry Standard Architecture (EISA) bus was
89 developed as an open alternative to the IBM MicroChannel bus.

91 The EISA bus provided some of the features of the IBM MicroChannel
92 bus while maintaining backward compatibility with cards made for
93 the older ISA bus. The EISA bus saw limited use between 1988 and
94 1995 when it was made obsolete by the PCI bus.

1310 Under some condition the effect of cache sync operation on

1312 This means that the store buffer is always asked to drain and

1314 is to replace the normal offset of cache sync operation (0x730)
1315 by another offset targeting an unmapped PL310 register 0x740.

1317 drain and waiting for all buffers empty.

1358 affecting Cortex-A9 MPCore with two or more processors (all
1359 current revisions). Under certain timing circumstances, a data
1360 cache line maintenance operation by MVA targeting an Inner
1361 Shareable memory region may fail to proceed up to either the
1362 Point of Coherency or to the Point of Unification of the

1601 This is a problem, because there's no guarantee the final
1602 destination of the symbol, or any candidate locations for a

1604 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1605 relocation in modules at all, and it makes little sense to add
1606 support.

2112 Compile in support for changing the PLL frequency from the
2113 S3C24XX series CPUfreq driver. The PLL takes time to settle
2114 after a frequency change, so by default it is not enabled.
2115
2116 This also means that the PLL tables for the selected CPU(s) will
2117 be built which may increase the size of the kernel image.

2151 Say Y to include the NWFPE floating point emulator in the kernel.
2152 This is necessary to run most binaries. Linux does not currently
2153 support floating point hardware so you need to say Y here even if
2154 your machine has an FPA or floating point co-processor podule.
2155
2156 You may say N here if you are going to load the Acorn FPEmulator
2157 early in the bootup.

2163 Say Y to include 80-bit support in the kernel floating-point
2164 emulator. Otherwise, only 32 and 64-bit support is compiled in.
2165 Note that gcc does not generate 80-bit operations by default,
2166 so in most cases this option only enlarges the size of the
2167 floating point emulator without any good reason.

2175 Say Y here to include the FAST floating point emulator in the kernel.
2176 This is an experimental much faster emulator which now also has full
2177 precision for the mantissa. It does not support any exceptions.
2178 It is very simple, and approximately 3-6 times faster than NWFPE.
2179
2180 It should be sufficient for most programs. It may be not suitable
2181 for scientific calculations, but you have to check this for yourself.
2182 If you do not feel you need a faster FP emulation you should better
2183 choose NWFPE.
