This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic
implementation of find_*_bit_le() in lib/find_next_bit.c or not.
For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which
enable CONFIG_GENERIC_FIND_NEXT_BIT.
But m68knommu wants to define own faster find_next_zero_bit_le() and
continues using generic find_next_{,zero_}bit().
(CONFIG_GENERIC_FIND_NEXT_BIT and !CONFIG_GENERIC_FIND_BIT_LE)

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.

This lets you select the page size of the kernel. For best
|
|
performance, a page size of 16KB is recommended. For best

|
compatibility with 32bit applications, a page size of 4KB should be
|

selected (the vast majority of 32bit binaries work perfectly fine
|
|
with a larger page size).

4KB For best 32bit compatibility
|

16KB For best performance
|

64KB For best performance, might give more overhead.

If you don't know what to do, choose 4KB.

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.
