2013-07-09net: mv643xx_eth: do not use port number as platform device idJonas Gorski
The port number is only local to the ethernet block, not global, so there can be two ethernet blocks both using the same port, like kirkwood with both using port 0. Fix this by using the array index offset for the allocated platform devices as the id. Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-07-09virtio_net: fix race in RX VQ processingMichael S. Tsirkin
virtio net called virtqueue_enable_cq on RX path after napi_complete, so with NAPI_STATE_SCHED clear - outside the implicit napi lock. This violates the requirement to synchronize virtqueue_enable_cq wrt virtqueue_add_buf. In particular, used event can move backwards, causing us to lose interrupts. In a debug build, this can trigger panic within START_USE. Jason Wang reports that he can trigger the races artificially, by adding udelay() in virtqueue_enable_cb() after virtio_mb(). However, we must call napi_complete to clear NAPI_STATE_SCHED before polling the virtqueue for used buffers, otherwise napi_schedule_prep in a callback will fail, causing us to lose RX events. To fix, call virtqueue_enable_cb_prepare with NAPI_STATE_SCHED set (under napi lock), later call virtqueue_poll with NAPI_STATE_SCHED clear (outside the lock).

2013-07-09virtio: support unlocked queue pollMichael S. Tsirkin
This adds a way to check ring empty state after enable_cb outside any locks. Will be used by virtio_net. Note: there's room for more optimization: caller is likely to have a memory barrier already, which means we might be able to get rid of a barrier here. Deferring this optimization until we do some benchmarking. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-07-09scsi_debug: fix do_device_access() with wrap around rangeAkinobu Mita
do_device_access() is a function that abstracts copying SG list from/to ramdisk storage (fake_storep). It must deal with the ranges exceeding actual fake_storep size, because such ranges are valid if virtual_gb is set greater than zero, and they should be treated as fake_storep is repeatedly mirrored up to virtual size. Unfortunately, it can't deal with the range which wraps around the end of fake_storep. A wrap around range is copied by two sg_copy_{from,to}_buffer() calls, but sg_copy_{from,to}_buffer() can't copy from/to in the middle of SG list, therefore the second call can't copy correctly. This fixes it by using sg_pcopy_{from,to}_buffer() that can copy from/to the middle of SG list. This also simplifies the assignment of sdb->resid in fill_from_dev_buffer(). Because fill_from_dev_buffer() is now only called once per command execution cycle. So it is not necessary to take care to decrease sdb->resid if fill_from_dev_buffer() is called more than once.

2013-07-09[SCSI] enable destruction of blocked devices which fail LUN scanningBart Van Assche
If something goes wrong during LUN scanning, e.g. a transport layer failure occurs, then __scsi_remove_device() can get invoked by the LUN scanning code for a SCSI device in state SDEV_CREATED_BLOCK and before the SCSI device has been added to sysfs (is_visible == 0). Make sure that even in this case the transition into state SDEV_DEL occurs. This avoids that __scsi_remove_device() can get invoked a second time by scsi_forget_host() if this last function is invoked from another thread than the thread that performs LUN scanning.

In the function prot_verify_write(), kmap_atomic()/kunmap_atomic() for data page and kmap_atomic()/kunmap_atomic() for protection information page are not nested each other. It worked perfectly before commit 3e4d3af501cccdc8a8cca41bdbe57d54ad7e7e73 ("mm: stack based kmap_atomic()"). Because the kmap_atomic slot KM_IRQ0 was used for data page and the slot KM_IRQ1 was used for protection page. But KM_types are gone and kmap_atomic() is using stack based implementation. So two different kmap_atomic() usages must be strictly nested now. This change ensures kmap_atomic() usage is strictly nested.

non LUN 0 configured expander With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created then SCSI scan procedure calls target_alloc, slave_alloc call back functions for LUN 0 and slave_destory() for same LUN 0. In these kind of cases within slave_destroy, pointer to scsi_target in _sas_device structure is set to NULL, following which when slave_alloc for LUN 1 is called then starget would not be set properly for this LUN. So, scsi_target pointer pointing to NULL value would lead to a crash later in the discovery procedure. To solve this issue set the sas_device's scsi_target pointer to scsi_device's scsi_target if it is NULL earlier in slave_alloc callback function.
