	  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.

config MLONGCALLS
	bool "Enable the -mlong-calls compiler option for big kernels"
	def_bool y if (!MODULES)
	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.

config 64BIT
	bool "64-bit kernel"
	depends on PA8X00
	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
	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. If
	  you say Y here, the kernel will run on many, but not all,
	  uniprocessor machines. On a uniprocessor 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.

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

	  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.

	prompt "Enable seccomp to safely compute untrusted bytecode"
	---help---
	  This kernel feature is useful for number crunching applications
	  that may need to compute untrusted bytecode during their
	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  If unsure, say Y. Only embedded should say N here.
