Linux-2.6.12-rc2v2.6.12-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!

+ * QLogic ISP2200 and ISP2300 Linux Driver Revision List File.
+ *
+ ********************************************************************
+ *
+ * Revision History
+ *
+ *  Rev  8.00.00b8	December 5, 2003	AV
+ *	- Instruct mid-layer to perform initial scan.
+ *
+ *  Rev  8.00.00b7	December 5, 2003	AV
+ *	- Resync with Linux Kernel 2.6.0-test11.
+ *	- Add basic NVRAM parser (extras/qla_nvr).
+ *
+ *  Rev  8.00.00b7-pre11 December 3, 2003	AV
+ *	- Sanitize the scsi_qla_host structure:
+ *	  - Purge unused elements.
+ *	  - Reorganize high-priority members (cache coherency).
+ *	- Add support for NVRAM access via a sysfs binary attribute:
+ *	  - Consolidate semaphore locking access.
+ *	- Fix more PCI posting issues.
+ *	- Add extras directory for dump/NVRAM tools.
+ *	- Remove unused qla_vendor.c file.
+ *
+ *  Rev  8.00.00b7-pre11 November 26, 2003	DG/AV
+ *	- Merge several patches from Christoph Hellwig [hch@lst.de]:
+ *	  - in Linux 2.6 both pci and the scsi layer use the generic
+ *	    dma direction bits, use them directly instead of the scsi
+ *	    and pci variants and the (noop) conversion routines.
+ *	- Fix _IOXX_BAD() usage for external IOCTL interface.
+ *	- Use atomic construct for HA loop_state member.
+ *	- Add generic model description text for HBA types.
+ *
+ *  Rev  8.00.00b7-pre5	November 17, 2003	AV
+ *	- Merge several patches from Christoph Hellwig [hch@lst.de]:
+ *	  - patch to split the driver into a common qla2xxx.ko and a
+ *	    qla2?00.ko for each HBA type - the latter modules are
+ *	    only very small wrappers, mostly for the firmware
+ *	    images, all the meat is in the common qla2xxx.ko.
+ *	  - make the failover code optional.
+ *	  - kill useless lock_kernel in dpc thread startup.
+ *	  - no need for modversions hacks in 2.6 (or 2.4).
+ *	  - kill qla2x00_register_with_Linux.
+ *	  - simplify EH code, cmd or it's hostdata can't be NULL, no
+ *	    need to search whether the host it's ours, the midlayer
+ *	    makes sure it won't call into a driver for some else
+ *	    host.
+ *	- Merge several patches from Jes Sorensen
+ *	  [jes@wildopensource.com]:
+ *	  - Call qla2x00_config_dma_addressing() before performing
+ *	    any consistent allocations. This is required since the
+ *	    dma mask settings will affect the memory
+ *	    pci_alloc_consistent() will return.
+ *	  - Call pci_set_consistent_dma_mask() to allow for 64 bit
+ *	    consistent allocations, required on some platforms such
+ *	    as the SN2.
+ *	  - Wait 20 usecs (not sure how long is really necessary,
+ *	    but this seems safe) after setting CSR_ISP_SOFT_RESET in
+ *	    the ctrl_status register as the card doesn't respond to
+ *	    PCI reads while in reset state. This causes a machine
+ *	    check on some architectures.
+ *	  - Flush PCI writes before calling udelay() to ensure the
+ *	    write is not sitting idle in-flight for a while before
+ *	    hitting the hardware.
+ *	  - Include linux/vmalloc.h in qla_os.c since it uses
+ *	    vmalloc().
+ *	  - Use auto-negotiate link speed when using default
+ *	    parameters rather than NVRAM settings. Disable NVRAM
+ *	    reading on SN2 since it's not possible to execute the
+ *	    HBA's BIOS on an SN2. I suggest doing something similar
+ *	    for all architectures that do not provide x86 BIOS
+ *	    emulation.
+ *	- Clean-up slab-cache allocations:
+ *	  - locking.
+ *	  - mempool allocations in case of low-memory situations.
+ *	- Fallback to GA_NXT scan if GID_PT call returns more than
+ *	  MAX_FIBRE_DEVICES.
+ *	- Preserve iterating port ID across GA_NXT calls in
+ *	  qla2x00_find_all_fabric_devs().
+ *	- Pre-calculate ASCII firmware dump length as to not incur the
+ *	  cost-to-calculate at each invocation of a read().
+ *
+ *  Rev  8.00.00b6	November 4, 2003	AV
+ *	- Add new 2300 TPX firmware (3.02.18).
+ *
+ *  Rev  8.00.00b6-pre25 October 20, 2003	RA/AV
+ *	- Resync with Linux Kernel 2.6.0-test9.
+ *	- Rework firmware dump process:
+ *	  - Use binary attribute within sysfs tree.
+ *	  - Add user-space tool (gdump.sh) to retrieve formatted
+ *	    buffer.
+ *	  - Add ISP2100 support.
+ *	- Use a slab cache for SRB allocations to reduce memory
+ *	  pressure.
+ *	- Initial conversion of driver logging methods to a new
+ *	  qla_printk() function which uses dev_printk (Daniel
+ *	  Stekloff, IBM).
+ *	- Further reduce stack usage in qla2x00_configure_local_loop()
+ *	  and qla2x00_find_all_fabric_devs().
+ *	- Separate port state used for routing of I/O's from port
+ *	  mgmt-login retry etc.
+ *
+ *  Rev  8.00.00b6-pre19 October 13, 2003	AV
+ *	- Resync with Linux Kernel 2.6.0-test7-bk5.

+ *	  - reduce scan time during 'port' RSCN events by only
+ *	    querying specified port ids.
+ *	  - Available on ISP23xx cards only.
+ *	- Increase maximum number of recognizable targets from 256
+ *	  to 512.
+ *	  - Backend changes were previously added to support TPX
+ *	    (2K logins) firmware.  Mid-layer can now scan for targets
+ *	    (H, B, T, L) where 512 < T >= 0.
+ *	- Remove IP support from driver.
+ *	  - Switch firmware types from IP->TP for ISP22xx and
+ *	    IPX->TPX for ISP23xx cards.
+ *	  - Remove files qla_ip.[ch].
+ *	- Remove type designations from firmware filenames.

+ *	- Resync with 6.06.00.
+ *	- Resync with Linux Kernel 2.6.0-test5-bk3.
+ *	- Add new 2300 IPX firmware (3.02.15).
+ *
+ *  Rev  8.00.00b5	July 31, 2003		AV
+ *	- Always create an fc_lun_t entry for lun 0 - as the mid-
+ *	  layer requires access to this lun for discovery to occur.
+ *	- General sanitizing:
+ *	  - Add generic firmware option definitions.
+ *	  - Generalize retrieval/update of firmware options.
+ *	  - Fix compile errors which occur with extended debug.
+ *	  - Handle failure cases for scsi_add_host() and
+ *	    down_interruptible().

+ *	- Resync with Linux Kernel 2.6.0-test2.
+ *	- Pass the complete loop_id, not the masked (0xff) value
+ *	  while issuing mailbox commands (qla_mbx.c/qla_fo.c/
+ *	  qla_iocb.c/qla_init.c).
+ *	- Properly handle zero-length return status for an RLC CDB.

+ *	  consistent format (domain, area, al_pa).
+ *	- General sanitizing:

+ *	    coherency.
+ *	  - Remove unused SCSI opcodes, endian-swap definitions.
+ *	  - Remove CMD_* pre-processor defines.
+ *	  - Remove unused SCSIFCHOTSWAP/GAMAP/MULTIHOST codes.
+ *	- Backout patch which added a per-scsi_qla_host scsi host
+ *	  spinlock, since mid-layer already defines one.
+ *	- Add new 2300 IPX firmware (3.02.15).
+ *
+ *  Rev  8.00.00b4	July 14, 2003		RA/DG/AV

+ *	      by the IRQ handler.
+ *	    - Remove extraneous calls to qla2x00_next() during I/O
+ *	      queuing.
+ *	  - Use list_splice_init() during qla2x00_done() handling
