2008-06-16powerpc/spufs: synchronize interaction between spu exception handling and ↵Luke Browning
time slicing Time slicing can occur at the same time as spu exception handling resulting in the wakeup of the wrong thread. This change uses the the spu's register_lock to enforce synchronization between bind/unbind and spu exception handling so that they are mutually exclusive.

2008-06-16powerpc/spufs: remove class_0_dsisr from spu exception handlingLuke Browning
According to the CBEA, the SPU dsisr is not updated for class 0 exceptions. spu_stopped() is testing the dsisr that was passed to it from the class 0 exception handler, so we return a false positive here. This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.

2008-06-15ide-generic: don't probe all legacy ISA IDE ports by defaultBartlomiej Zolnierkiewicz
We can't probe all legacy ISA IDE ports by default as the resources may be occupied by other ISA devices. Add "probe_mask" module parameter and probe only first two ISA IDE ports by default leaving the decision about probing the rest to the user (systems with ISA ide2-6 should be very, very rare).

2008-06-15[SCSI] scsi_host regression: fix scsi host leakMike Christie
commit 9c7701088a61cc0cf8a6e1c68d1e74e3cc2ee0b7 Author: Dave Young <hidave.darkstar@gmail.com> Date: Tue Jan 22 14:01:34 2008 +0800 scsi: use class iteration api Isn't a correct replacement for the original hand rolled host lookup. The problem is that class_find_child would get a reference to the host's class device which is never released. Since the host class device holds a reference to the host gendev, the host can never be freed. In 2.6.26 we started using class_find_device, and this function also gets a reference to the device, so we end up with an extra ref and the host will not get released. This patch adds a put_device to balance the class_find_device() get. I kept the scsi_host_get in scsi_host_lookup, because the target layer is using scsi_host_lookup and it looks like it needs the SHOST_DEL check.
