2013-08-13mm: save soft-dirty bits on file pagesCyrill Gorcunov
Andy reported that if file page get reclaimed we lose the soft-dirty bit if it was there, so save _PAGE_BIT_SOFT_DIRTY bit when page address get encoded into pte entry. Thus when #pf happens on such non-present pte we can restore it back.

2013-08-13mm: save soft-dirty bits on swapped pagesCyrill Gorcunov
Andy Lutomirski reported that if a page with _PAGE_SOFT_DIRTY bit set get swapped out, the bit is getting lost and no longer available when pte read back. To resolve this we introduce _PTE_SWP_SOFT_DIRTY bit which is saved in pte entry for the page being swapped out. When such page is to be read back from a swap cache we check for bit presence and if it's there we clear it and restore the former _PAGE_SOFT_DIRTY bit back. One of the problem was to find a place in pte entry where we can save the _PTE_SWP_SOFT_DIRTY bit while page is in swap. The _PAGE_PSE was chosen for that, it doesn't intersect with swap entry format stored in pte.

2013-08-13memcg: don't initialize kmem-cache destroying work for root cachesAndrey Vagin
struct memcg_cache_params has a union. Different parts of this union are used for root and non-root caches. A part with destroying work is used only for non-root caches.

2013-08-13ipv6: make unsolicited report intervals configurable for mldHannes Frederic Sowa
Commit cab70040dfd95ee32144f02fade64f0cb94f31a0 ("net: igmp: Reduce Unsolicited report interval to 1s when using IGMPv3") and 2690048c01f32bf45d1c1e1ab3079bc10ad2aea7 ("net: igmp: Allow user-space configuration of igmp unsolicited report interval") by William Manley made igmp unsolicited report intervals configurable per interface and corrected the interval of unsolicited igmpv3 report messages resendings to 1s. Same needs to be done for IPv6: MLDv1 (RFC2710 7.10.): 10 seconds MLDv2 (RFC3810 9.11.): 1 second Both intervals are configurable via new procfs knobs mldv1_unsolicited_report_interval and mldv2_unsolicited_report_interval. (also added .force_mld_version to ipv6_devconf_dflt to bring structs in line without semantic changes) v2: a) Joined documentation update for IPv4 and IPv6 MLD/IGMP unsolicited_report_interval procfs knobs. b) incorporate stylistic feedback from William Manley v3: a) add new DEVCONF_* values to the end of the enum (thanks to David Miller) Cc: Cong Wang <xiyou.wangcong@gmail.com> Cc: William Manley <william.manley@youview.com> Cc: Benjamin LaHaise <bcrl@kvack.org> Cc: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

2013-08-13ethernet/arc/arc_emac - fix NAPI "work > weight" warningAlexey Brodkin
Initially I improperly set a boundary for maximum number of input packets to process on NAPI poll ("work") so it might be more than expected amount ("weight").

2013-08-13ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id.Pravin B Shelar
Using inner-id for tunnel id is not safe in some rare cases. E.g. packets coming from multiple sources entering same tunnel can have same id. Therefore on tunnel packet receive we could have packets from two different stream but with same source and dst IP with same ip-id which could confuse ip packet reassembly.

2013-08-13tcp: reset reordering est. selectively on timeoutYuchung Cheng
On timeout the TCP sender unconditionally resets the estimated degree of network reordering (tp->reordering). The idea behind this is that the estimate is too large to trigger fast recovery (e.g., due to a IP path change). But for example if the sender only had 2 packets outstanding, then a timeout doesn't tell much about reordering. A sender that learns about reordering on big writes and loses packets on small writes will end up falsely retransmitting again and again, especially when reordering is more likely on big writes. Therefore the sender should only suspect that tp->reordering is too high if it could have gone into fast recovery with the (lower) default estimate.

2013-08-14PM / QoS: Fix workqueue deadlock when using pm_qos_update_request_timeout()Stephen Boyd
pm_qos_update_request_timeout() updates a qos and then schedules a delayed work item to bring the qos back down to the default after the timeout. When the work item runs, pm_qos_work_fn() will call pm_qos_update_request() and deadlock because it tries to cancel itself via cancel_delayed_work_sync(). Future callers of that qos will also hang waiting to cancel the work that is canceling itself. Let's extract the little bit of code that does the real work of pm_qos_update_request() and call it from the work function so that we don't deadlock. Before ed1ac6e (PM: don't use [delayed_]work_pending()) this didn't happen because the work function wouldn't try to cancel itself.

2013-08-13gianfar: Add flow control supportClaudiu Manoil
eTSEC has Rx and Tx flow control capabilities that may be enabled through MACCFG1[Rx_Flow, Tx_Flow] bits. These bits must not be set however when eTSEC is operated in Half-Duplex mode. Unfortunately, the driver currently sets these bits unconditionally. This patch adds the proper handling of the PAUSE frame capability register bits by implementing the ethtool -A interface. When pause autoneg is enabled, the controller uses the phy's capability to negotiate PAUSE frame settings with the link partner and reconfigures its Rx_Flow and Tx_Flow settings to match the capabilities of the link partner. If pause autoneg is off, the PAUSE frame generation may be forced manually (ethtool -A). Flow control is disabled by default now. This implementation is inspired by the tg3 driver.

Data chunks already have memory accounting so noting needs to happen. For control chunks, add stubs handlers. Signed-off-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S.

Ensure that the definition of ax88172a_info matches the declaration seen by users and silence sparse warnings about symbols without declarations in the global namespace by moving the declaration into the shared header asix.h.

Make functions that are only referenced from ops structures static, they do not need to be in the global namespace and sparse complains about this. Signed-off-by: Mark Brown <broonie@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
