Pull ARM updates from Russell King:
"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)"

Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

CardBus cards.

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.
