The patch titled
htirq: tidy up the htirq code
has been removed from the -mm tree. Its filename is
htirq-tidy-up-the-htirq-code.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: htirq: tidy up the htirq code
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
This moves the declarations for the architecture helpers into
include/linux/htirq.h from the generic include/linux/pci.h. Hopefully this
will make this distinction clearer.
htirq.h is included where it is needed.
The dependency on the msi code is fixed and removed.
The Makefile is tidied up.
