2008-02-20[POWERPC] cell: fix spurious false return from spu_trap_data_{map,seg}Andre Detsch
At present, the __spufs_trap_data_map and __spu_trap_data_seq functions exit if spu->flags has the SPU_CONTEXT_SWITCH_ACTIVE set. This was resulting in suprious returns from these functions, as they may be legitimately called when we have this bit set. We only use it in these two sanity checks, so this change removes the flag completely. This fixes hangs in the page-fault path of SPE apps.

2008-02-20[POWERPC] Fix dt_mem_next_cell() to read the full addressBecky Bruce
dt_mem_next_cell() currently does of_read_ulong(). This does not allow for the case where #size-cells and/or #address-cells = 2 on a 32-bit system, as it will end up reading 32 bits instead of the expected 64. Change it to use of_read_number instead and always return a u64.

2008-02-19firewire: fw-sbp2: (try to) avoid I/O errors during reconnectStefan Richter
While fw-sbp2 takes the necessary time to reconnect to a logical unit after bus reset, the SCSI core keeps sending new commands. They are all immediately completed with host busy status, and application clients or filesystems will break quickly. The SCSI device might even be taken offline: http://bugzilla.kernel.org/show_bug.cgi?id=9734 The only remedy seems to be to block the SCSI device until reconnect. Alas the SCSI core has no useful API to block only one logical unit i.e. the scsi_device, therefore we block the entire Scsi_Host. This currently corresponds to an SBP-2 target. In case of targets with multiple logical units, we need to satisfy the dependencies between logical units by carefully tracking the blocking state of the target and its units. We block all logical units of a target as soon as one of them needs to be blocked, and keep them blocked until all of them are ready to be unblocked. Furthermore, as the history of the old sbp2 driver has shown, the scsi_block_requests() API is a minefield with high potential of deadlocks. We therefore take extra measures to keep logical units unblocked during __scsi_add_device() and during shutdown. This avoids I/O errors during reconnect in many but alas not in all cases. There may still be errors after a re-login had to be performed. Also, some bridges have been seen to cease fetching management ORBs if I/O went on up until a bus reset. In these cases, all management ORBs time out after mgt_orb_timeout. The old sbp2 driver is less vulnerable or maybe not vulnerable to this, for as yet unknown reasons.
