sh: move fpu_counter into ARCH specific thread_struct

2013-11-13T03:09:13Z

Only a couple of arches (sh/x86) use fpu_counter in task_struct so it can be moved out into ARCH specific thread_struct, reducing the size of task_struct for other arches.

Pull networking changes from David Miller: "Noteworthy changes this time around: 1) Multicast rejoin support for team driver, from Jiri Pirko. 2) Centralize and simplify TCP RTT measurement handling in order to reduce the impact of bad RTO seeding from SYN/ACKs. Also, when both timestamps and local RTT measurements are available prefer the later because there are broken middleware devices which scramble the timestamp. From Yuchung Cheng. 3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel memory consumed to queue up unsend user data. From Eric Dumazet. 4) Add a "physical port ID" abstraction for network devices, from Jiri Pirko. 5) Add a "suppress" operation to influence fib_rules lookups, from Stefan Tomanek. 6) Add a networking development FAQ, from Paul Gortmaker. 7) Extend the information provided by tcp_probe and add ipv6 support, from Daniel Borkmann. 8) Use RCU locking more extensively in openvswitch data paths, from Pravin B Shelar. 9) Add SCTP support to openvswitch, from Joe Stringer. 10) Add EF10 chip support to SFC driver, from Ben Hutchings. 11) Add new SYNPROXY netfilter target, from Patrick McHardy. 12) Compute a rate approximation for sending in TCP sockets, and use this to more intelligently coalesce TSO frames. Furthermore, add a new packet scheduler which takes advantage of this estimate when available. From Eric Dumazet. 13) Allow AF_PACKET fanouts with random selection, from Daniel Borkmann. 14) Add ipv6 support to vxlan driver, from Cong Wang" Resolved conflicts as per discussion. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1218 commits) openvswitch: Fix alignment of struct sw_flow_key. netfilter: Fix build errors with xt_socket.c tcp: Add missing braces to do_tcp_setsockopt caif: Add missing braces to multiline if in cfctrl_linkup_request bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize vxlan: Fix kernel panic on device delete. net: mvneta: implement ->ndo_do_ioctl() to support PHY ioctls net: mvneta: properly disable HW PHY polling and ensure adjust_link() works icplus: Use netif_running to determine device state ethernet/arc/arc_emac: Fix huge delays in large file copies tuntap: orphan frags before trying to set tx timestamp tuntap: purge socket error queue on detach qlcnic: use standard NAPI weights ipv6:introduce function to find route for redirect bnx2x: VF RSS support - VF side bnx2x: VF RSS support - PF side vxlan: Notify drivers for listening UDP port changes net: usbnet: update addr_assign_type if appropriate driver/net: enic: update enic maintainers and driver driver/net: enic: Exposing symbols for Cisco's low latency driver ...

SH7619: fix typo in Ether platform data

2013-08-22T21:32:18Z

Commit 06a64f91da72cb5827e2bedef2ead60a123fd66e (SH7619: fix Ether support) has a typo in the 'phy_interface' field name of the platform data which causes build error -- fix it. Signed-off-by: Sergei Shtylyov Signed-off-by: David S. Miller

sh_eth: remove 'register_type' field from 'struct sh_eth_plat_data'

2013-08-21T00:10:41Z

Now that the 'register_type' field of the 'sh_eth' driver's platform data is not used by the driver anymore, it's time to remove it and its initializers from the SH platform code. Also move *enum* declaring values for this field from to the local driver's header file as they're only needed by the driver itself now... Signed-off-by: Sergei Shtylyov Signed-off-by: David S.

SH7619: fix Ether support

2013-08-21T00:10:40Z

The 'sh_eth' driver's probe will crash as the platform code is hopelessly behind the platform data -- it passes PHY ID instead of 'struct sh_eth_plat_data *'. Strangely, both commit d88a3ea6fa4c (SH7619 add ethernet controler support) that added the platform code and commit 71557a37adb5 ([netdrvr] sh_eth: Add SH7619 support) were done in about the same time, yet the latter one added 'struct sh_eth_plat_data' and the platform code didn't ever get updated... Add the proper platform data and fix off-by-one memory resource end error, while at it... Signed-off-by: Sergei Shtylyov Signed-off-by: David S. Miller

sh: delete __cpuinit usage from all sh files

2013-07-14T23:36:53Z

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/sh uses of the __cpuinit macros from all C files. Currently sh does not have any __CPUINIT used in assembly files.

sh_eth: get SH7724 support out of #ifdef

2013-06-08T06:38:24Z

Get the SH7724 code/data in the driver out of #ifdef by adding "r8a7724-ether" to the platform driver's ID table. Change the Ether platform device's name in the SH platform code accordingly. Signed-off-by: Sergei Shtylyov Signed-off-by: David S. Miller

Get the SH77{34|63} specific code/data in the driver out of #ifdef by adding "sh7734-gether" and "sh7763-gether" to the platform driver's ID table. Note that we have to split the 'struct sh_eth_cpu_data' instance into two due to #ifdef inside it; note that we can kill the duplicate sh_eth_set_rate_gether().
