New Revision: 225883
URL: http://svn.freebsd.org/changeset/base/225883
Log:
Fix a corner case in the HAL debugging changes, where ah was NULL.
Although I tried to fix this earlier by introducing HALDEBUG_G(), it
turns out there seem to be other cases where the pointer value is still
NULL.
* Fix DO_HALDEBUG() and the HALDEBUG macro to check whether ah is NULL
before deferencing it
* Remove HALDEBUG_G() as it's no longer needed
This is hopefully a merge candidate for 9.0-RELEASE as enabling
debugging at startup could result in a kernel panic.
