- Find out whether you have a PCI motherboard. PCI is the name of a
- bus system, i.e. the way the CPU talks to the other stuff inside
- your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
- VESA. If you have PCI, say Y, otherwise N.
-
- The PCI-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, contains valuable
- information about which PCI hardware does work under Linux and which
- doesn't.

- * WARNING - magic here

- * Ok, this is a horrid hack below, but marginally better than the

- * hvReleaseData in C as in the #if 0 section here. However, gcc
- * refuses to believe that (u32)&x is a constant expression, so will
- * not allow the xMsNucDataOffset field to be properly initialized.
- * So, we declare hvReleaseData in inline asm instead. We use inline
- * asm, rather than a .S file, because the assembler won't generate
- * the necessary relocation for the LparMap either, unless that symbol
- * is declared in the same source file. Finally, we put the asm in a
- * dummy, attribute-used function, instead of at file scope, because
- * file scope asms don't allow contraints. We want to use the "i"
- * constraints to put sizeof() and offsetof() expressions in there,
- * because including asm/offsets.h in C code then stringifying causes
