[Xen-devel] [PATCH] Disable watchdog in dump_registers

[Andrew Lyon <andrew.lyon@xxxxxxxxx>]

Add watchdog_disable/watchdog_enable around dump_registers to avoid trigging
watchdog if serial port output is slow.

Patch generated for xen-unstable but it will also apply to 3.4.2.

Signed-off-by: Andrew Lyon <andrew.lyon@xxxxxxxxx>
