	  This is the processor type of your CPU.  This information is

	depends on PA8X00
	help
	  If you configure the kernel to include many drivers built-in instead
	  as modules, the kernel executable may become too big, so that the
	  linker will not be able to resolve some long branches and fails to link
	  your vmlinux kernel. In that case enabling this option will help you
	  to overcome this limit by using the -mlong-calls compiler option.

	  Usually you want to say N here, unless you e.g. want to build
	  a kernel which includes all necessary drivers built-in and which can
	  be used for TFTP booting without the need to have an initrd ramdisk.

	  Enabling this option will probably slow down your kernel.

	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.

	  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.

	help
	  Say Y if you want to build the parisc kernel as a kind of
	  self-extracting executable.

	  If you say N here, the kernel will be compressed with gzip
	  which can be loaded by the palo bootloader directly too.

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

config SMP
	bool "Symmetric multi-processing support"
	help
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more
	  than one CPU, say Y.

	  If you say N here, the kernel will run on uni- and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine.
	  On a uniprocessor machine, the kernel will run faster if you say N.

	  See also <file:Documentation/admin-guide/lockup-watchdogs.rst> and the SMP-HOWTO
	  available at <https://www.tldp.org/docs.html#howto>.

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

	  Multi-core scheduler support improves the CPU scheduler's decision

	  increased overhead in some places. If unsure say N here.

config IRQSTACKS
	bool "Use separate kernel stacks when processing interrupts"

	help
	  If you say Y here the kernel will use separate kernel stacks
	  for handling hard and soft interrupts.  This can help avoid
	  overflowing the process kernel stacks.

	  for kernel and initramfs as opposed to list of segments as
	  accepted by previous system call.
