A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

and later HP3000 series). The PA-RISC Linux project home page is

This is the processor type of your CPU. This information is
|
|
used for optimizing purposes. In order to compile a kernel
|
|
that can run on all 32-bit PA CPUs (albeit not optimally fast),
|
|
you can specify "PA7000" here.
|
|
|
|
Specifying "PA8000" here will allow you to select a 64-bit kernel
|
|
which is required on some machines.

Enable this if you want to support 64bit kernel on PA-RISC platform.
|
|
|
|
At the moment, only people willing to use more than 2GB of RAM,
|
|
or having a 64bit-only capable PA-RISC machine should say Y here.
|
|
|
|
Since there is no 64bit userland on PA-RISC, there is no point to
|
|
enable this option otherwise. The 64bit kernel is significantly bigger
|
|
and slower than the 32bit one.

---help---
|

This enables support for systems with more than one CPU. If you have
|
|
a system with only one CPU, like most personal computers, say N. If
|
|
you have a system with more than one CPU, say Y.
|
|
|
|
If you say N here, the kernel will run on single and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If
|
|
you say Y here, the kernel will run on many, but not all,
|
|
singleprocessor machines. On a singleprocessor machine, the kernel
|
|
will run faster if you say N here.
