| | | | | | | | e2fcf261076b ("interrupt: Fix saving irq/ipl when linux drivers are disabled") changed the stack layout for interrupt handlers, but missed updating kdb_kintr's code that tries to mangle it. This restores the control-alt-d shortcut.

* copyinmsg: Set msgh_size inside copyinmsg rather than the callerSamuel Thibault2022-08-281-2/+4
