2007-07-12dm: use kmem_cache macroAlasdair G Kergon
Use new KMEM_CACHE() macro and make the newly-exposed structure names more meaningful. Also remove some superfluous casts and inlines (let a modern compiler be the judge).

2007-07-12Video mode probing support for the new x86 setup codeH. Peter Anvin
Video mode probing for the new x86 setup code. This code breaks down different drivers into modules. This code deliberately drops support for a lot of the vendor-specific mode probing present in the assembly version, since a lot of those probes have been found to be stale in current versions of those chips -- frequently, support for those modes have been dropped from recent video BIOSes due to space constraints, but the video BIOS signatures are still the same.

2007-07-12Use a new CPU feature word to cover features that are spread aroundVenki Pallipadi
Some Intel features are spread around in different CPUID leafs like 0x5, 0x6 and 0xA. Make this feature detection code common across i386 and x86_64.
