Fix this by going back to legacy interrupts. [Thread "Isochronous streaming with VT6315 OHCI", http://marc.info/?t=139049641500003] With smaller packets, the loss of IRQs happens too but only very rarely --- rarely eneough that it was not yet possible for me to determine whether QUIRK_NO_MSI is an actual fix for this rare variation of this chip bug. I am keeping QUIRK_CYCLE_TIMER off of VT6315 rev >= 1 because this has been verified by myself with certainty. On the other hand, I am also keeping QUIRK_CYCLE_TIMER on for VT6315 rev 0 because I don't know at this time whether this revision accesses Cycle Timer non-atomically like most of the other VIA OHCIs are known to do.

VT6315 Series Firewire Controller [1106:3403] I now got a card with $ lspci -nn VIA Technologies, Inc. VT6315 Series Firewire Controller [1106:3403] (rev 01) and this works fine with MSI enabled. Second, I tested this VT6315 rev 1 without CYCLE_TIMER quirk flag using http://me.in-berlin.de/~s5r6/linux1394/utils/test_cycle_time_v20100125.c and found that this chip does in fact access the cycle timer atomically. Things I can't test because I don't have the hardware: - whether VT6315 rev 0 really needs QUIRK_CYCLE_TIMER, - whether the VT6320 PCI device needs QUIRK_CYCLE_TIMER, - whether the VT6325 and VT6330 PCIe devices need QUIRK_CYCLE_TIMER and QUIRK_NO_MSI. Hence, just add a whitelist entry specifically for VT6315 rev >= 1 without any quirk flags. Before this entry we need an extra entry to catch VT6315 rev <= 0 due to how our ID matching logic works.

That change raised the minimum address at which protocol drivers and user programs can register for request reception from 0x0001'0000'0000 to 0x8000'0000'0000. It turned out that at least one vendor-specific protocol exists which uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921 For the time being, revert most of commit fcd46b34425d so that affected protocols work like with kernel v3.13 and before. Just keep the valid documentation parts from the regressing commit, and the ability to identify controllers which could be programmed to accept >32 bit physical DMA addresses. The rest of fcd46b34425d should probably be brought back as an optional instead of default feature.

This commit apply a workaround for this quirk. They often fail transactions due to gap_count mismatch. This state is changed by generating bus reset. The fw_schedule_bus_reset() is an exported symbol in firewire-core. But there are no header for public. This commit moves its prototype from drivers/firewire/core.h to include/linux/firewire.h. This mismatch still affects bus management before generating this bus reset. It still takes a time to call driver's probe() because transactions are still often failed.
