There is no need to use {get,put}_cpu() when we already have a spinlock to
protect against multiple processors running simultaneously.

SMP systems require per-cpu local clock event devices in order to enable
HRT support. One a BF561, we can use local core timer for this purpose.
Originally, there was one global core-timer clock event device set up for
core A.
To accomplish this feat, we need to split the gptimer0/core timer logic
so that each is a standalone clock event. There is no requirement that
we only have one clock event source anyways. Once we have this, we just
define per-cpu clock event devices for each local core timer.

The gpio label size is 16 char, but the current code uses a longer name

Attempting to use the MPU while doing XIP out of parallel flash hooked up
to the async memory bus would often result in random crashes as the MPU
slowly corrupted memory.
The fallout here is that the async banks gain MPU protection from user
space too. So any accesses have to go through the mmap() interface rather
than just using hardcoded pointers.

Sometimes a SMP system will randomly panic at boot. This is due to caches
being out of sync when one core tries to signal the other. So when one
core calls another via IPI, flush the data caches.

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".
When the callback is called for special messages, the driver creates
an uevent for the received message. The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.
udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.

The device driver must allocate memory for IUCV buffers with GFP_DMA,
because IUCV cannot address memory above 2GB (31bit addresses only).
Because the IUCV ignores the higher bits of the address, sending and
receiving IUCV data with this driver might cause memory corruptions.
