* mmc: remove redundant debug information from sdhci and wbsdPierre Ossman2007-07-25
| | | | | | | Remove the extra debugging output that now is properly printed by the core. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: proper debugging output in corePierre Ossman2007-07-25
| | | | | | | | Make sure that the debugging output in the core is complete. This should allow us to clean up all the extra debug output that each and every other host driver seems to contain. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: be more verbose about card insertions/removalPierre Ossman2007-07-25
| | | | | | | Let the user know that the kernel actually detected the card by printing some basic information in dmesg. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: Don't hold lock when releasing an added cardPierre Ossman2007-07-25
| | | | | | | | When the card has been added to the device model, it might be bound to a card driver. Therefore, we have to release the host lock when trying to remove it as we otherwise might deadlock with the driver. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: add a might_sleep() to mmc_claim_host()Pierre Ossman2007-07-25
| | | | | | | | In the normal case, the host lock can be claimed directly. When it cannot, the caller will sleep. Make sure we don't have any latent bugs by always calling might_sleep(). Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: check error bits before command completionPierre Ossman2007-07-25
| | | | | | | | Some controllers signal "command complete" even on failures (which they are allowed to do according to the spec). Make sure we check the error bits first so we don't get any false positives. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* Fix failure exits in asus-laptopAl Viro2007-07-24
| | | | | | | | | | | | | | | | Fallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f. However, looking at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger at all (we never get to asus_led_exit() if registration fails) and if that registration fails, we actually leak stuff. IOW, it's worse than just replacing class_dev with dev in there - the tests themselves had been papering over the lousy cleanup logics.

* Use resource_size_t for serial port IO addressesJosh Boyer2007-07-24
| | | | | | | | | | | | | | | | | | | | At present, various parts of the serial code use unsigned long to define resource addresses. This is a problem, because some 32-bit platforms have physical addresses larger than 32-bits, and have mmio serial uarts located above the 4GB point. This patch changes the type of mapbase in both struct uart_port and struct plat_serial8250_port to resource_size_t, which can be configured to be 64 bits on such platforms. The mapbase in serial_struct can't safely be changed, because that structure is user visible.

| * IB/ehca: Support small QP queuesStefan Roscher2007-07-21
| | | | | | | | | | | | | | | | | | | | | | eHCA2 supports QP queues that can be as small as 512 bytes. This greatly reduces memory overhead for consumers that use lots of QPs with small queues (e.g. RDMA-only QPs). Apart from dealing with firmware, this code needs to manage bite-sized chunks of kernel pages, making sure that no kernel page is shared between different protection domains.

| | | | | | | | | | | | | | | | | | | | | | Add support for MR pages larger than 4K on eHCA2. This reduces firmware memory consumption. If enabled via the mr_largepage module parameter, the MR page size will be determined based on the MR length and the hardware capabilities -- if the MR is >= 16M, 16M pages are used, for example.

| * IB/mlx4: Fix error path in create_qp_common()Roland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | The error handling code at err_wrid in create_qp_common() does not handle a userspace QP attached to an SRQ correctly, since it ends up in the else clause of the if statement. This means it tries to kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers. Fix this so we only free the wrid arrays for kernel QPs. Pointed out by Michael S. Tsirkin <mst@dev.mellanox.co.il>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * mlx4_core: Change command token on timeoutRoland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The FW command token is currently only updated on a command completion event. This means that on command timeout, the same token will be reused for new command, which results in a mess if the timed out command *does* eventually complete. This is the same change as the patch for mthca from Michael S. Tsirkin <mst@dev.mellanox.co.il> that was just merged. It seems sensible to avoid gratuitous differences in FW command processing between mthca and mlx4. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipath_layer.[ch] code was an attempt to provide a single interface for the ipath verbs and ipath_ether code to use. As verbs functionality increased, the layer's functionality became insufficient and the verbs code broke away to interface directly to the driver. The failed attempt to get ipath_ether upstream was the final nail in the coffin and now it sits quietly in a dark kernel.org corner waiting for someone to notice the smell and send it along to it's final resting place.

| * | [SCSI] bsg: make class backlinksJames Bottomley2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, bsg doesn't make class backlinks (a process whereby you'd get a link to bsg in the device directory in the same way you get one for sg). This is because the bsg device is uninitialised, so the class device has nothing it can attach to. The fix is to make the bsg device point to the cdevice of the entity creating the bsg, necessitating changing the bsg_register_queue() prototype into a form that takes the generic device.
