2012-05-22caif-shm: synchronize caif flow controlArun Murthy
In the shm tx work function caif flow control is turned ON and without acquiring the spin lock. In the rx callback cail flow control is turned off. The expected sequence would be on caif writing message to modem via shm, if shm finds that there is no empty space then, it is not sets caif flow control to OFF. On shm receiving messages from modem, it sets caif flow control to ON. Now this since this is in interrupt context, there are chances of this fucntion being preeempted by the caif OFF that is being set in the tx work function. Hence create a seperate workqueue and two work functions to turn caif flow control ON and OFF. With this implementation it is ensured that caif flow control is turned OFF first by tx work function and turned ON by the rx callback.

2012-05-22shrm-net : remove netif_carrier_off/on callsHemant Ramdasi
This patch removes netif_carrier_off() call from machine suspend sequence. Also removes netif_carrier_on() call from resume sequence. This error is introduced because of the below behaviour. Important control message PNS_PEP_STATUS_IND message from phonet stack is getting dropped sometimes in the APE sleep-wakeup transition. It happens because, the Qdisc (between Phonet and SHRM) changes to "noop" when APE goes to sleep. The normal Qdisc in operation in pfifo_fast. When APE wakes up, the transition to pfast_fifo is not fast enough as it is done in a workqueue. So before the switch happens, APE receives 3 packets very quickly and must grant credits in any of the 3 packets. This does not happen. Hence modem cannot send any new packet as it has exhausted all its credits and APE cannot send credit-grant message as it will not receive any new packet. This leads to a deadlock situation for IP data transfer.

There are chances of preemtion happening between the check and access to GOP during which if modem has reset, then we will end up with a system freeze. Hence secure that the check and access to GOP happends at a time without preemption.

2012-05-22u8500-shrm: ensure hostaccess_port is high while accessing GOPArun Murthy
In places of APE handling modem ISR, its clear that modem is awake since it has sent the interrupt and it should be waiting for the ACK for the interrupt. But still its better to check since there are cases where modem behaves unexpectedly.

2012-05-22u8500-shrm: reset boot_state on ape initiated modem resetArun Murthy
the variable boot_state is used to monitor the check the access for the GOP register. Hence on APE initiated modem reset, this flag must be reset as there can be possibility that very soon after ape initiated modem reset, there is some 100msec for modem to send to send modem reset ack and in the mean time if ape tries to access the GOP register then it might end up with system freeze. Hence reset the flag on ape initiated modem reset.
