290172e790 [WATCHDOG] hpwdt: Fix kdump when using hpwdt
When the "hpwdt" module is loaded (even if the /dev/watchdog device is not
opened), then kdump does not work. The panic kernel either does not start at
all or crash in various places.

The problem is that hpwdt_pretimeout is registered with register_die_notifier()
with the highest possible priority. Because it returns NOTIFY_STOP, the
crash_nmi_callback which is also registered with register_die_notifier()
is never executed. This causes the shutdown of other CPUs to fail.

Reverting the order is no option: The crash_nmi_callback executes HLT
and so never returns normally. Because of that, it must be executed as
last notifier, which currently is done.

So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

060264133b [WATCHDOG] hpwdt: set the mapped BIOS address space as executable
The address provided by the SMBIOS/DMI CRU information is mapped via
ioremap() in the virtual address space.  However, since the address is
executed (i.e.  call'd), we need to set that pages as executable.

Without that, I get following oops on a HP ProLiant DL385 G2
machine with BIOS from 05/29/2008 when I trigger crashdump:

Bugzilla #9868: On Intel motherboards with the ICH9 based I/O controllers
(Like DP35DP and DG33FB) the iTCO timer counts but it doesn't reboot the

This patch fixes the setting of the Book-E watchdog timer interval setup

On initialization the period bits have to be masked before setting

In WDIOC_SETTIMEOUT ioctl we have to use the correct mask.

7c2500f17d [WATCHDOG] ib700wdt.c - fix buffer_underflow bug
This fixes Bug 11399:
if ibwdt_set_heartbeat(int t) is called with value 30 then
the check "if ((t < 0) || (t > 30))" in ibwdt_set_heartbeat
is not going to fail because t == 30, but in the loop, the
check wd_times[i] > t is never going to be true because
none of the wd_times are greater than the value of t (i.e. 30).
So we are exiting the loop with i == -1 and therefore setting
wd_margin to -1 which is wrong.

The watchdog driver mpc8xx_wdt.c was a device interface to
arch/ppc/syslib/m8xx_wdt.c for MPC8xx hardware. Now that ARCH=ppc is
gone, this driver is of no more use. For ARCH=powerpc, MPC8xx hardware
is supported by mpc8xxx_wdt.c.
