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

Hi all,
This is yesterday's patch set updated to apply cleanly (and hopefully
work) on top of 2.6.25-git13. Basically the only change since yesterday
is the sync with the rtc subsystem updates, which converted 3 drivers
(rtc-x1205, rtc-pcf8563 and rtc-isl1208).
The plan is to send this to Linus
Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.

Update most new-style i2c drivers to use standard module aliasing

There's an external PCI device connected to it

Therefore my dts entry for this device looks like :

mpc52xx_uart_int and __uart_put_char both try to acquire the
