2008-11-059p: Make all client spin locks IRQ safeTom Tucker1-4/+6
The client lock must be IRQ safe. Some of the lock acquisition paths took regular spin locks. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-11-059p: rdma: Set trans prior to requesting async connection opsTom Tucker1-1/+3
The RDMA connection manager is fundamentally asynchronous. Since the async callback context is the client pointer, the transport in the client struct needs to be set prior to calling the first async op.

2008-11-04libata: Fix a potential race condition in ata_scsi_park_show()Elias Oltmanns1-3/+4
Peter Moulder has pointed out that there is a slight chance that a negative value might be passed to jiffies_to_msecs() in ata_scsi_park_show(). This is fixed by saving the value of jiffies in a local variable, thus also reducing code since the volatile variable jiffies is accessed only once.

2008-11-04sata_nv: fix generic, nf2/3 detection regressionTejun Heo1-28/+25
All three flavors of sata_nv's are different in how their hardreset behaves. * generic: Hardreset is not reliable. Link often doesn't come online after hardreset. * nf2/3: A little bit better - link comes online with longer debounce timing. However, nf2/3 can't reliable wait for the first D2H Register FIS, so it can't wait for device readiness or classify the device after hardreset. Follow-up SRST required. * ck804: Hardreset finally works. The core layer change to prefer hardreset and follow up changes exposed the above issues and caused various detection regressions for all three flavors. This patch, hopefully, fixes all the known issues and should make sata_nv error handling more reliable. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-04sata_promise: add ATA engine reset to reset opsMikael Pettersson1-0/+20
Promise ATA engines need to be reset when errors occur. That's currently done for errors detected by sata_promise itself, but it's not done for errors like timeouts detected outside of the low-level driver. The effect of this omission is that a timeout tends to result in a sequence of failed COMRESETs after which libata EH gives up and disables the port. At that point the port's ATA engine hangs and even reloading the driver will not resume it. To fix this, make sata_promise override ->hardreset on SATA ports with code which calls pdc_reset_port() on the port in question before calling libata's hardreset. PATA ports don't use ->hardreset, so for those we override ->softreset instead. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-03mv643xx_eth: fix SMI bus access timeoutsLennert Buytenhek1-3/+6
The mv643xx_eth mii bus implementation uses wait_event_timeout() to wait for SMI completion interrupts. If wait_event_timeout() would return zero, mv643xx_eth would conclude that the SMI access timed out, but this is not necessarily true -- wait_event_timeout() can also return zero in the case where the SMI completion interrupt did happen in time but where it took longer than the requested timeout for the process performing the SMI access to be scheduled again. This would lead to occasional SMI access timeouts when the system would be under heavy load. The fix is to ignore the return value of wait_event_timeout(), and to re-check the SMI done bit after wait_event_timeout() returns to determine whether or not the SMI access timed out.

2008-11-03ftrace: use kretprobe trampoline name to test in outputSteven Rostedt1-18/+21
Impact: ia64+tracing build fix When a function is kprobed, the return address is set to the kprobe_trampoline, or something similar. This caused the output of the trace to look confusing when the parent seemed to be this "kprobe_trampoline" function. To fix this, Abhishek Sagar added a test of the instruction pointer of the parent to see if it matched the kprobe_trampoline. If it did, the output would print a "[unknown/kretprobe'd]" instead. Unfortunately, not all archs do this the same way, and the trampoline function may not be exported, which causes failures in builds. This patch will compare the name instead of the pointer to see if it matches. This prevents us from depending on a function from being exported, and should work on all archs. The worst that can happen is that an arch might use a different name and then we go back to the confusing output. At least the arch will still build.
