Introduce watchdog driver for a various range of Mellanox Ethernet and
Infiniband switch systems.

Watchdog driver for Mellanox watchdog devices, implemented in
programmable logic device.

Main and auxiliary watchdog devices can exist on the same system.
There are several actions that can be defined in the watchdog:
system reset, start fans on full speed and increase a counter.
The last 2 actions are performed without a system reset.
Actions without reset are provided for auxiliary watchdog devices,
which is optional.
Access to HW registers is performed through generic
regmap interface.

There are 2 types of HW watchdog implementations.
Type 1: actual HW timeout can be defined as power of 2 msec.
e.g. timeout 20 sec will be rounded up to 32768 msec.;
maximum timeout period is 32 sec (32768 msec.);
get time-left isn't supported
Type 2: actual HW timeout is defined in sec. and it's the same as
user-defined timeout;
maximum timeout is 255 sec;
get time-left is supported;

Watchdog driver is probed from the common mlx_platform driver.

   - Fix the swapped outb() parameters in the KASLR code

   - Fix the entry stack handling for XEN PV to respect that XEN PV
     systems enter the function already on the current thread stack and
     not on the trampoline.

   - Fix kexec load failure caused by using a stale value when the
     kexec_buf structure is reused for subsequent allocations.

Johannes Berg says:

====================
Just a few small fixes:
 * avoid trying to operate TDLS when not connection,
   this is not valid and led to issues
 * count TTL-dropped frames in mesh better
 * deal with new WiGig channels in regulatory code
 * remove a WARN_ON() that can trigger due to benign
   races during device/driver registration
 * fix nested netlink policy maxattrs (syzkaller)
 * fix hwsim n_limits (syzkaller)
 * propagate __aligned(2) to a surrounding struct
 * return proper error in virt_wifi error path
