* Driver core: Constify struct sysfs_ops in struct kobj_typeEmese Revfy2010-03-072-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

* driver-core: Add attribute argument to class_attribute show/storeAndi Kleen2010-03-071-1/+4
| | | | | | | | | | | | | | | | | | | | Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* bitops: rename for_each_bit() to for_each_set_bit()Akinobu Mita2010-03-066-11/+11
| | | | | | | | | | | | | | | | | | | | Rename for_each_bit to for_each_set_bit in the kernel source tree. To permit for_each_clear_bit(), should that ever be added. The patch includes a macro to map the old for_each_bit() onto the new for_each_set_bit(). This is a (very) temporary thing to ease the migration.

| * RDMA/cxgb3: Doorbell overflow avoidance and recoverySteve Wise2010-02-246-5/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T3 hardware doorbell FIFO overflows can cause application stalls due to lost doorbell ring events. This has been seen when running large NP IMB alltoall MPI jobs. The T3 hardware supports an xon/xoff-type flow control mechanism to help avoid overflowing the HW doorbell FIFO. This patch uses these interrupts to disable RDMA QP doorbell rings when we near an overflow condition, and then turn them back on (and ring all the active QP doorbells) when when the doorbell FIFO empties out. In addition if an doorbell ring is dropped by the hardware, the code will now recover. Design: cxgb3: - enable these DB interrupts - in the interrupt handler, schedule work tasks to call the ULPs event handlers with the new events. - ring all the qset txqs when an overflow is detected. iw_cxgb3: - disable db ringing on all active qps when we get the DB_FULL event - enable db ringing on all active qps and ring all active dbs when we get the DB_EMPTY event - On DB_DROP event: - disable db rings in the event handler - delay-schedule a work task which rings and enables the dbs on all active qps. - in post_send and post_recv logic, don't ring the db if it's disabled.

This can cause tx compl processing to be scheduled on another cpu concurrently which can result in a panic. This if fixed by calling napi complete() after tx/mcc compl processing but before re-enabling interrupts (via a cq notify).

Sorry for the mess. ] This patch is based on the RFC of Stanislaw Gruszka. More specifically it fixes two possible races: - One, described by Stanislaw, may lead to permanent disabling of the Tx queue. This is fixed by adding the smp_wmb() to propagate the BD consumer change towards the memory. - Second may lead to bnx2x_start_xmit() returning NETDEV_TX_BUSY. This is fixed by taking a tx_lock() before rechecking the number of available Tx BDs. thanks, vlad Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Vladislav Zolotarov <vladz@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

| | * | | | b43: fall back gracefully to PIO mode after fatal DMA errorsLinus Torvalds2010-02-263-7/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the b43 driver just automatically fall back to PIO mode when DMA doesn't work. The driver already told the user to do it, so rather than have the user reload the module with a new flag, just make the driver do it automatically. We keep the message as an indication that something is wrong, but now just automatically fall back to the hopefully working PIO case.

This is causing baseband related issues on AR9160 and AR9130 based chipsets, which can lock up under certain conditions. This patch fixes these issues by overriding the initvals, effectively disabling RIFS for all affected chipsets. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Acked-by: Luis R.

The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure" is to first detect when data transmission stalls and then to recover from this situation with a reset of the radio or the firmware, depending on how bad the transmission failures are. Unfortunately we have found that this change causes excessive resets with its current detection algorithm. It also performs its recovery action when none is really needed, like when we are not associated. Revert this change until the issues have been addressed.
