444d1d9bb5 [PATCH] qlogic lockup fix
If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call
qla2x00_free_device() to clean up.  But because ha->dpc_pid hasn't been set
yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started
yet.  It does wait_for_completion() against an uninitialised completion struct
and the kernel hangs up.

Fix it by initialising ha->dpc_pid a bit earlier.

86cd6baa82 [SCSI] qla2xxx: Remove bad call to fc_remove_host() during probe failure.
fc_remove_host() should only be called after a scsi_host has
been successfully added via scsi_add_host() -- any failures
while qla2xxx probing would result in an incorrect call to
fc_remove_host() during cleanup.

7524f9b9e7 [SCSI] qla2xxx: Use dma_get_required_mask() in determining the 'ideal' DMA mask.
In order to efficiently utilise the ISP's IOCB
request-queue, use the dma_get_required_mask() function to
determine the use of command-type 2 or 3 IOCBs when queueing
SCSI commands.  This applies to ISP2[123]xx chips only, as
the ISP24xx uses command-type 7 IOCBs which use 64bit DSDs.

77d7414361 [SCSI] qla2xxx: Cleanup FC remote port registration.
Cleanup FC remote port registration.

Due to the inherent behaviour (an immediate scan) of adding
a 'target'-role-capable rport via fc_remote_port_add(),
split the registration into two steps -- addition as
unknown-type role, then use fc_remote_port_rolchg() with
appropriate role (based on PLOGI/PRLI bits).  This allows
for a more cleaner rport->dd_data management as can be seen
with the simplified qla2xxx_slave_alloc() function.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
