2007-10-16net: Fix new EMAC driver for NAPI changesBenjamin Herrenschmidt
net: Fix new EMAC driver for NAPI changes This fixes the new EMAC driver for the NAPI updates. The previous patch by Roland Dreier (already applied) to do that doesn't actually work. This applies on top of it makes it work on my test Ebony machine. This patch depends on "net: Add __napi_sycnhronize() to sync with napi poll" posted previously.

2007-10-16e1000e: don't poke PHY registers to retreive link statusAuke Kok
Apparently poking the link status registers when autonegotiation is running on the PHY might botch the PHY link on 80003es2lan devices. While this is a very rare condition we can completely avoid it alltogether by just using the MAC link bits to provide the proper information to ethtool.

2007-10-16[netdrvr] forcedeth: remove in-driver copy of net_device_statsJeff Garzik
A copy of struct net_device_stats now lives in struct net_device, making in-driver copies a waste of memory. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2007-10-16[netdrvr] forcedeth: improved probe info; dev_printk() cleanupsJeff Garzik
main change: * greatly improve per-NIC probe diagnostic output. Similar to other net drivers, print out MAC address, PHY info, and various hardware and software flags that may be relevant. other changes: * similar to other net drivers, only print the initial version message when we have found at least one board. * don't bother to print error message when pci_enable_device() fails, it will do so for us. * use dev_printk() rather than printk() in nv_probe(). This gives use a standardized output similar to the rest of the kernel, and eliminates the need to manually print out PCI bus id. * use DRV_NAME constant where appropriate * clean struct pci_driver indentation Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2007-10-17firewire: adopt read cycle timer ABI from raw1394Stefan Richter
This duplicates the read cycle timer feature of raw1394 (added in Linux 2.6.21) in firewire-core's userspace ABI. The argument to the ioctl is reordered though to ensure 32/64 bit compatibility.

2007-10-17firewire: fw-ohci: enforce read order for selfID generationStefan Richter
It seems unlikely, but access to self_id_cpu[0] could at least in theory be deferred until after the loop over self_id_cpu[1..n] or even after the subsequent reg_read. Enforce the desired order by a read barrier. Also prevent the reg_read from being reordered relative to the for loop. This isn't necessary if the loop's conditional printk counts as an implicit barrier, but better make it explicit. (self_id_cpu[] is a coherent DMA buffer.)

2007-10-17firewire: fw-sbp2: use an own workqueue (fix system responsiveness)Stefan Richter
Firewire-sbp2 did very uncooperative things in the kernel's shared workqueue: Sleeping until reception of management status from the target for up to 2 seconds, and performing SCSI inquiry and all of the setup of SCSI command set drivers via scsi_add_device. If there were transient or permanent error conditions, this caused long blockage of the kernel's events process, noticeable e.g. by blocked keyboard input. We now allocate a workqueue process exclusive to fw-sbp2. As a side effect, this also increases parallelism of fw-sbp2's login and reconnect work versus fw-core's device discovery and device update work which is performed in the shared workqueue.

2007-10-17firewire: fw-sbp2: expose module parameter for workaroundsStefan Richter
On rare occasions, the ability to set one of the workaround flags at runtime may save the day. People who experience I/O errors with firewire-sbp2 while the old sbp2 driver worked for them should try workarounds=1 and report to the devel mailinglist whether that improves things. Firewire-sbp2 defaults to the SCSI stack's maximum transfer size per command, while sbp2 limits them to 128 kBytes. Flag 1 accomplishes just that.

2007-10-17firewire: fw-sbp2: always enable IRQs before calling command ORB callbackStefan Richter
On IOMMU-less noncoherent architectures, orb->callback will memcpy the whole SCSI command buffer for READ-like SCSI commands. It is therefore friendlier to enable IRQs before the call, like before patch "Add ref-counting for sbp2 orbs".

2007-10-16ieee1394: csr1212: proper refcountingStefan Richter
At least since nodemgr got rid of coarse global locking, accesses to struct csr1212_keyval's reference counter should be atomic and coupled with proper barriers. Also, calls to csr1212_keep_keyval(kv) should occur before kv is being used. (We probably should convert refcnt to struct kref, but how to keep csr1212_destroy_keyval's implementation non-recursively then?) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2007-10-16ieee1394: nodemgr: fix leak of struct csr1212_keyvalStefan Richter
csr1212_keep_keyval(kv) in nodemgr_process_root_directory was unbalanced if ne->vendor_name_kv already exists. This happens for example if eth1394 or raw1394 modify the local config ROM and it is parsed again. As a bonus, the attempt to add the vendor_name_kv sysfs attribute when it already exists is now fixed for good. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2007-10-16ieee1394: Fix kthread stopping in nodemgr_host_threadSatyam Sharma
The nodemgr host thread can exit on its own even when kthread_should_stop is not true, on receiving a signal (might never happen in practice, as it ignores signals). But considering kthread_stop() must not be mixed with kthreads that can exit on their own, I think changing the code like this is clearer. This change means the thread can cut its sleep short when receive a signal but looking at the code around, that sounds okay (and again, it might never actually recieve a signal in practice).
