We currently allocate synic structures in hv_sync_init(), but there's no way for the driver to know about the allocation failure and it may continue to use the uninitialized pointers. Solve this by introducing helpers for allocating and freeing and doing the allocation before the on_each_cpu() call in vmbus_bus_init().

If device is initialized from device tree, but has no interrupt assigned, uio will still try to request and interrupt old way, fails, and fails registration.

This fake carrier is designed to help FMC users understand how a carrier driver works, and to experiment the behaviour with EEPROM reprogramming (with a mezzanine driver commited later).

This module offers registration services for both carriers (i.e. devices) and mezzanines (i.e. drivers). The matching for devices and drivers is performed according to the IPMI standard for FRU devices (Field Replaceable Units). The code includes support for parsing an SDB tree if present in the FPGA, and dumping it for diagnostics. SDB is not mandatory.

The OF code uses irqsafe locks everywhere except in a handful of functions for no obvious reasons. Since the conversion from the old rwlocks, this now triggers lockdep warnings when used at interrupt time. At least one driver (ibmvscsi) seems to be doing that from softirq context. This converts the few non-irqsafe locks into irqsafe ones, making them consistent with the rest of the code.

Some systems that don't need wake-on-lan may choose to power down the chip on system standby. Upon resume, the power on causes the boot code to startup and initialize the hardware. On one new platform, this is causing the device to go into a bad state due to a race between the driver and boot code, once every several hundred resumes. The same race exists on open since we come up from a power on. This patch adds a wait for boot code signature at the beginning of tg3_init_hw() which is common to both cases. If there has not been a power-off or the boot code has already completed, the signature will be present and poll_fw() returns immediately. Also return immediately if the device does not have firmware.

First the type of igmp_retrans (which is the actual counter of igmp_resend parameter) is changed to u8 to be able to store values up to 255 (as per documentation). There are two races that were hidden there and which are easy to trigger after the previous fix, the first is between bond_resend_igmp_join_requests and bond_change_active_slave where igmp_retrans is set and can be altered by the periodic. The second race condition is between multiple running instances of the periodic (upon execution it can be scheduled again for immediate execution which can cause the counter to go < 0 which in the unsigned case leads to unnecessary igmp retransmissions). Since in bond_change_active_slave bond->lock is held for reading and curr_slave_lock for writing, we use curr_slave_lock for mutual exclusion. We can't drop them as there're cases where RTNL is not held when bond_change_active_slave is called. RCU is unlocked in bond_resend_igmp_join_requests before getting curr_slave_lock since we don't need it there and it's pointless to delay. The decrement is moved inside the "if" block because if we decrement unconditionally there's still a possibility for a race condition although it is much more difficult to hit (many changes have to happen in a very short period in order to trigger) which in the case of 3 parallel running instances of this function and igmp_retrans == 1 (with check bond->igmp_retrans-- > 1) is: f1 passes, doesn't re-schedule, but decrements - igmp_retrans = 0 f2 then passes, doesn't re-schedule, but decrements - igmp_retrans = 255 f3 does the unnecessary retransmissions.

If the bond device is supposed to get the first slave's MAC address and the first enslavement fails then we need to reset the master's MAC otherwise it will stay the same as the failed slave device. We do it after err_undo_flags since that is the first place where the MAC can be changed and we check if it should've been the first slave and if the bond's MAC was set to it because that err place is used by multiple locations prior to changing the master's MAC address.
