2011-11-02mmc: Fix pm_notifier obeying deferred resume (part 2)Dmitry Shmidt

2011-11-02mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resumeMaxim Levitsky
commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e upstream. If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

2011-11-02mmc: core: Add deferred bus resume policy.San Mehat
A card driver can now specify that the underlying bus should *not* auto-resume with the rest of the system. This is useful for reducing resume latency as well as saving power when the card driver is not using the bus. In the future, we'll add support for manual suspend Signed-off-by: San Mehat <san@google.com>

2011-09-05net: Reorder incoming packets in PPPoLAC and PPPoPNS.Chia-chi Yeh
PPP handles packet loss but does not work with out of order packets. This change performs reordering of incoming data packets within a sliding window of one second. Since sequence number is optional, receiving a packet without it will drop all queued packets. Currently the logic is triggered by incoming packets, so queued packets have to wait till another packet is arrived. It is done for simplicity since no additional locks or threads are required. For reliable protocols, a retransmission will kick it. For unreliable protocols, queued packets just seem like packet loss. Time-critical protocols might be broken, but they never work with queueing anyway. Signed-off-by: Chia-chi Yeh <chiachi@android.com>
2011-09-05net: New iface_stat module to monitor persistent network statsAshish Sharma
Adding a new module that tracks the number of bytes/packets transfered by a network interface, even after the interface has been removed. This is relevant to track the total data usage in mobile devices whose interfaces are added and removed quite frequently (WiFi, Bluetooth, 3G,..). Monitoring is done only for devices that are configured with a valid IP address (check to exclude virtual/loopback/tunnel interfaces).

2011-09-05net: activity_stats: Add statistics for network transmission activityMike Chan
When enabled, tracks the frequency of network transmissions (inbound and outbound) and buckets them accordingly. Buckets are determined by time between network activity. Each bucket represents the number of network transmisions that were N sec or longer apart. Where N is defined as 1 << bucket index. This network pattern tracking is particularly useful for wireless networks (ie: 3G) where batching network activity closely together is more power efficient than far apart. New file: /proc/net/stat/activity output: Min Bucket(sec) Count 1 7 2 0 4 1 8 0 16 0 32 2 64 1 128 0 Change-Id: I4c4cd8627b872a55f326b1715c51bc3bdd6e8d92 Signed-off-by: Mike Chan <mike@android.com>

Audio is broken if buffers are in external ram and the external ram clock is turned off. To fix it: * In platform data, ext_ram is replaced with two settings: ext_ram_rx and ext_ram_tx which control whether the buffer will be in iram or external ram. * imx-pcm.c no longer hardwired to put all capture streams in external ram. * if IRAM is disabled in the defconfig or if iram_alloc fails, then ext_ram_rx or ext_ram_tx are updated so they will show whether the buffers were allocated in external ram or iram. * During audio playback or capture, enable external ram clock if the buffer is in external ram.

2011-05-09PM / Runtime: Fix pm_runtime_suspended()Rafael J. Wysocki
There are some situations (e.g. in __pm_generic_call()), where pm_runtime_suspended() is used to decide whether or not to execute a device's (system) ->suspend() callback. The callback is not executed if pm_runtime_suspended() returns true, but it does so for devices that don't even support runtime PM, because the power.disable_depth device field is ignored by it. This leads to problems (i.e. devices are not suspened when they should), so rework pm_runtime_suspended() so that it returns false if the device's power.disable_depth field is different from zero.

2011-05-05net: PPPoPNS and PPPoLAC fixes for android.Chia-chi Yeh
* Fix a bitmask in PPPoPNS and rename constants in PPPoPNS and PPPoLAC. * Fix a potential deadlock while releasing PPPoLAC/PPPoPNS socket. PPP driver guarantees that no thread will be executing start_xmit() after returning from ppp_unregister_channel(). To achieve this, a spinlock (downl) is used. In pppolac_release(), ppp_unregister_channel() is called after sk_udp is locked. At the same time, another thread might be running in pppolac_xmit() with downl. Thus a deadlock will occur if the thread tries to lock sk_udp. The same situation might happen on sk_raw in pppopns_release(). * Force PPPoLAC and PPPoPNS to bind an interface before creating PPP channel. It is common to manipulate the routing table after configuring PPP device. Since both PPPoLAC and PPPoPNS run over IP, care must be taken to make sure that there is no loop in the routing table. Although this can be done by adding a host route, it might still cause problems when the interface is down for some reason. To solve this, this patch forces both drivers to bind an interface before creating PPP channel, so the system will not re-route the tunneling sockets to another interface when the original one is down. Another benefit is that now the host route is no longer required, so there is no need to remove it when PPP channel is closed. * Avoid sleep-inside-spinlock in PPPoLAC and PPPoPNS. Since recv() and xmit() are called with a spinlock held, routines which might sleep cannot be used. This issue is solved by following changes: Incoming packets are now processed in backlog handler, recv_core(), instead of recv(). Since backlog handler is always executed with socket spinlock held, the requirement of ppp_input() is still satisfied. Outgoing packets are now processed in workqueue handler, xmit_core(), instead of xmit(). Note that kernel_sendmsg() is no longer used to prevent touching dead sockets. In release(), lock_sock() and pppox_unbind_sock() ensure that no thread is in recv_core() or xmit(). Then socket handlers are restored before release_sock(), so no packets will leak in backlog queue. * Fix msg_iovlen in PPPoLAC and PPPoPNS. Although any positive value should work (which is always true in both drivers), the correct value should be 1. Signed-off-by: Chia-chi Yeh <chiachi@android.com>
