Linus Torvalds 1205b62390 Included in this update: 
- Florian Fainelli noticed that userspace segfaults caused by the lack
   of kernel-userspace helpers was hard to diagnose; we now issue a
   warning when userspace tries to use the helpers but the kernel has
   them disabled.
 
 - Ben Dooks wants compatibility for the old ATAG serial number with DT
   systems.
 
 - Some cleanup of assembly by Nicolas Pitre.
 
 - User accessors optimisation from Vincent Whitchurch.
 
 - More robust kdump on SMP systems from Yufen Wang.
 
 - Sebastian Andrzej Siewior noticed problems with the SMP "boot_lock"
   on RT kernels, and so we convert the Versatile series of platforms
   to use a raw spinlock instead, consolidating the Versatile
   implementation.  We entirely remove the boot_lock on OMAP systems,
   where it's unnecessary.  Further patches for other systems will be
   submitted for the following merge window.
 
 - Start switching old StrongARM-11x0 systems to use gpiolib rather
   than their private GPIO implementation - mostly PCMCIA bits.
 
 - ARM Kconfig cleanups.
 
 - Cleanup a mostly harmless mistake in the recent Spectre patch in 4.20
   (which had the effect that data that can be placed into the init
   sections was incorrectly always placed in the rodata section.)

menuconfig PCCARD
tristate "PCCard (PCMCIA/CardBus) support"
depends on !UML
---help---
Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
computer. These are credit-card size devices such as network cards,
modems or hard drives often used with laptops computers. There are
actually two varieties of these cards: 16 bit PCMCIA and 32 bit
CardBus cards.
To compile this driver as modules, choose M here: the
module will be called pcmcia_core.
if PCCARD
config PCMCIA
tristate "16-bit PCMCIA support"
select CRC32
default y
---help---
This option enables support for 16-bit PCMCIA cards. Most older
PC-cards are such 16-bit PCMCIA cards, so unless you know you're
only using 32-bit CardBus cards, say Y or M here.
To use 16-bit PCMCIA cards, you will need supporting software in
most cases. (see the file <file:Documentation/Changes> for
location and details).
To compile this driver as modules, choose M here: the
module will be called pcmcia.
If unsure, say Y.
config PCMCIA_LOAD_CIS
bool "Load CIS updates from userspace"
depends on PCMCIA
select FW_LOADER
default y
help
Some PCMCIA cards require an updated Card Information Structure (CIS)
to be loaded from userspace to work correctly. If you say Y here,
and your userspace is arranged correctly, this will be loaded
automatically using the in-kernel firmware loader and the hotplug
subsystem, instead of relying on cardmgr from pcmcia-cs to do so.
If unsure, say Y.
config CARDBUS
bool "32-bit CardBus support"
depends on PCI
default y
---help---
CardBus is a bus mastering architecture for PC-cards, which allows
for 32 bit PC-cards (the original PCMCIA standard specifies only
a 16 bit wide bus). Many newer PC-cards are actually CardBus cards.
To use 32 bit PC-cards, you also need a CardBus compatible host
bridge. Virtually all modern PCMCIA bridges do this, and most of
them are "yenta-compatible", so say Y or M there, too.
If unsure, say Y.

select PCCARD_NONSTATIC if PCMCIA != n
---help---
This option enables support for CardBus host bridges. Virtually
all modern PCMCIA bridges are CardBus compatible. A "bridge" is
the hardware inside your computer that PCMCIA cards are plugged
into.
To compile this driver as modules, choose M here: the
module will be called yenta_socket.
If unsure, say Y.

chip.

tristate "i82365 compatible bridge support"
depends on PCMCIA && ISA
select PCCARD_NONSTATIC
help
Say Y here to include support for ISA-bus PCMCIA host bridges that
are register compatible with the Intel i82365. These are found on
older laptops and ISA-bus card readers for desktop systems. A
"bridge" is the hardware inside your computer that PCMCIA cards are
plugged into. If unsure, say N.
config TCIC
tristate "Databook TCIC host bridge support"
depends on PCMCIA && ISA
select PCCARD_NONSTATIC
help
Say Y here to include support for the Databook TCIC family of PCMCIA
host bridges. These are only found on a handful of old systems.
"Bridge" is the name used for the hardware inside your computer that
PCMCIA cards are plugged into. If unsure, say N.

Say Y here to enable debugging for the SoC PCMCIA layer.
You will need to choose the debugging level either via the
kernel command line, or module options depending whether
you build the drivers as modules.
The kernel command line options are:
sa11xx_core.pc_debug=N
pxa2xx_core.pc_debug=N
The module option is called pc_debug=N
In all the above examples, N is the debugging verbosity
level.
