+	  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.

+	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.

+	  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.

+	default y
+	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.

+	  Support PARISC cpu topology definition.
+
+config SCHED_MC
+	bool "Multi-core scheduler support"
+	depends on PARISC_CPU_TOPOLOGY && PA8X00
+	help
+	  Multi-core scheduler support improves the CPU scheduler's decision
+	  making when dealing with multi-core CPU chips at a cost of slightly
+	  increased overhead in some places. If unsure say N here.
+
+config IRQSTACKS
+	bool "Use separate kernel stacks when processing interrupts"
+	default y
+	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.
+
+config TLB_PTLOCK
+	bool "Use page table locks in TLB fault handler"
+	depends on SMP
+	default n
+	help
+	  Select this option to enable page table locking in the TLB
+	  fault handler. This ensures that page table entries are
+	  updated consistently on SMP machines at the expense of some
+	  loss in performance.

+	help
+	  kexec is a system call that implements the ability to shutdown your
+	  current kernel, and to start another kernel.  It is like a reboot
+	  but it is independent of the system firmware.   And like a reboot
+	  you can start any kernel with it, not just Linux.
+
+	  It is an ongoing process to be certain the hardware in a machine
+	  shutdown, so do not be surprised if this code does not
+	  initially work for you.
+
+config KEXEC_FILE
+	bool "kexec file based system call"
+	select KEXEC_CORE
+	select KEXEC_ELF
+	help
+	  This enables the kexec_file_load() System call. This is
+	  file based and takes file descriptors as system call argument
+	  for kernel and initramfs as opposed to list of segments as
+	  accepted by previous system call.
