powerpc/mm: Fix section mismatch warning

[linux-2.6-block.git] / Documentation / watchdog / watchdog-parameters.txt

This file provides information on the module parameters of many of
the Linux watchdog drivers.  Watchdog driver parameter specs should
be listed here unless the driver has its own driver-specific information
file.


See Documentation/admin-guide/kernel-parameters.rst for information on
providing kernel parameters for builtin drivers versus loadable
modules.
