Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.There also seems to be noone willing to bring this port back into a usable
state.This patch therefore removes the v850 port.
If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.Signed-off-by: Adrian Bunk

The inline assembly in drivers/watchdog/hpwdt.c was incredibly broken,
and included all the function prologue and epilogue stuff, even though
it was itself then inside a C function where the compiler would add its
own prologue and epilogue on top of it all.This then just _happened_ to work if you had exactly the right compiler
version and exactly the right compiler flags, so that gcc just happened
to not create any prologue at all (the gcc-generated epilogue wouldn't
matter, since it would never be reached).But the more proper way to fix it is to simply not do this. Move the
inline asm to the top level, with no surrounding function at all (the
better alternative would be to remove the prologue and make it actually
use proper description of the arguments to the inline asm, but that's a
bigger change than the one I'm willing to make right now).Tested-by: S.Çağlar Onur

On Book-E SMP systems each core has its own private watchdog. If only one
watchdog is enabled, when the core that doesn't enable the watchdog is hung,
system can't reset because no watchdog is running on it. That's bad. It
means we must enable watchdogs on both cores.We can use smp_call_function() to send appropriate messages to all the other
cores to enable and update the watchdog.Signed-off-by: Chen Gong

I noticed this while testing the latest code. I'm not sure if it is required,
but the normal (or LSB) timeout value is set to zero, so the MSB should
be as well to stay consistent.If the chip revision is >= 8, set MSB of the 16-bit timeout value to zero
when disabling the watchdog in it8712f_wdt_disable().Signed-off-by: Andrew Paprocki

This patch corrects an error in the driver it8712f_wdt. You cannot set
the 16-bit WDT_TIMEOUT access as a 16-bit outw, because the byte
ordering will be wrong. So just do the high 8 bits as a separate
access.Signed-off-by: Oliver Schuster

On my HP DL380 G5 system running a 64-bit kernel, loading the hpwdt
driver causes a crash because the driver attempts to ioremap an
invalid physical address. This is because the driver has an incorrect
definition of the SMBIOS table entry point structure: the table
address is only a 32-bit quantity, and making it a u64 means that the
high-order 32 bits end up containing garbage.Correcting the structure definition fixes the driver so that it loads
without any problems on my system.Signed-off-by: Roland Dreier

Hp is providing a Hardware WatchDog Timer driver that will only work with the
specific HW Timer located in the HP ProLiant iLO 2 ASIC. The iLO 2 HW Timer
will generate a Non-maskable Interrupt (NMI) 9 seconds before physically
resetting the server, by removing power, so that the event can be logged to
the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory
(NVRAM). The logging of the event is performed using the HP ProLiant ROM via
an Industry Standard access known as a BIOS Service Directory Entry.Signed-off-by: Thomas Mingarelli
