PTP: convert class code to use dev_groups

2013-07-27T01:05:17Z

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the ptp class code to use the correct field. Acked-by: Richard Cochran Signed-off-by: Greg Kroah-Hartman

build some drivers only when compile-testing

2013-06-24T23:41:32Z

Some drivers can be built on more platforms than they run on. This is a burden for users and distributors who package a kernel. They have to manually deselect some (for them useless) drivers when updating their configs via oldconfig. And yet, sometimes it is even impossible to disable the drivers without patching the kernel. Introduce a new config option COMPILE_TEST and make all those drivers to depend on the platform they run on, or on the COMPILE_TEST option. Now, when users/distributors choose COMPILE_TEST=n they will not have the drivers in their allmodconfig setups, but developers still can compile-test them with COMPILE_TEST=y. Now the drivers where we use this new option: * PTP_1588_CLOCK_PCH: The PCH EG20T is only compatible with Intel Atom processors so it should depend on x86. * FB_GEODE: Geode is 32-bit only so only enable it for X86_32. * USB_CHIPIDEA_IMX: The OF_DEVICE dependency will be met on powerpc systems -- which do not actually support the hardware via that method. * INTEL_MID_PTI: It is specific to the Penwell type of Intel Atom device. [v2] * remove EXPERT dependency [gregkh - remove chipidea portion, as it's incorrect, and also doesn't apply to my driver-core tree] Signed-off-by: Jiri Slaby Cc: Andrew Morton Cc: Linus Torvalds Cc: Jeff Mahoney Cc: Alexander Shishkin Cc: linux-usb@vger.kernel.org Cc: Florian Tobias Schandinat Cc: linux-geode@lists.infradead.org Cc: linux-fbdev@vger.kernel.org Cc: Richard Cochran Cc: netdev@vger.kernel.org Cc: Ben Hutchings Cc: "Keller, Jacob E" Signed-off-by: Greg Kroah-Hartman

ptp: dynamic allocation of PHC char devices

2013-04-12T22:22:45Z

As network adapters supporting PTP are becoming more common, machines with many NICs suddenly have many PHCs, too. The current limit of eight /dev/ptp* char devices (and thus, 8 network interfaces with PHC) is insufficient. Let the ptp driver allocate the char devices dynamically. Tested with 28 PHCs, removing and re-adding some of them. Thanks to Ben Hutchings for advice leading to simpler and cleaner patch.

ptp_pch: eliminate a number of sparse warnings

2013-03-27T16:48:31Z

This fixes a number of sparse warnings like: warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] *addr got unsigned int * warning: Using plain integer as NULL pointer Additionally this fixes a warning from checkpatch.pl like: WARNING: sizeof pch_param.station should be sizeof(pch_param.station) Signed-off-by: Sahara Signed-off-by: David S.

Pull networking changes from David Miller: 1) Allow to dump, monitor, and change the bridge multicast database using netlink. From Cong Wang. 2) RFC 5961 TCP blind data injection attack mitigation, from Eric Dumazet. 3) Networking user namespace support from Eric W. Biederman. 4) tuntap/virtio-net multiqueue support by Jason Wang. 5) Support for checksum offload of encapsulated packets (basically, tunneled traffic can still be checksummed by HW). From Joseph Gasparakis. 6) Allow BPF filter access to VLAN tags, from Eric Dumazet and Daniel Borkmann. 7) Bridge port parameters over netlink and BPDU blocking support from Stephen Hemminger. 8) Improve data access patterns during inet socket demux by rearranging socket layout, from Eric Dumazet. 9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and Jon Maloy. 10) Update TCP socket hash sizing to be more in line with current day realities. The existing heurstics were choosen a decade ago. From Eric Dumazet. 11) Fix races, queue bloat, and excessive wakeups in ATM and associated drivers, from Krzysztof Mazur and David Woodhouse. 12) Support DOVE (Distributed Overlay Virtual Ethernet) extensions in VXLAN driver, from David Stevens. 13) Add "oops_only" mode to netconsole, from Amerigo Wang. 14) Support set and query of VEB/VEPA bridge mode via PF_BRIDGE, also allow DCB netlink to work on namespaces other than the initial namespace. From John Fastabend. 15) Support PTP in the Tigon3 driver, from Matt Carlson. 16) tun/vhost zero copy fixes and improvements, plus turn it on by default, from Michael S. Tsirkin. 17) Support per-association statistics in SCTP, from Michele Baldessari. And many, many, driver updates, cleanups, and improvements.
