config PA7000

	---help---
	  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.

	help
	  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.

config PARISC_PAGE_SIZE_4KB
	bool "4KB"
	help
	  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.

config SMP

	select USE_GENERIC_SMP_HELPERS
	---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.

	  See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
	  available at <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.
