The fibre channel firmware provides a timer which is similar in purpose
to the fibre channel transport's device loss timer. The effect of this
timer is to extend the total time that a target will be missing beyond
the value associated with the transport's timer. This patch changes
the firmware timer to a default of one second which significantly reduces
the lag between when a target goes missing and the notification of the
fibre channel transport.

The add_preferred_console call in rtas_console.c was not causing the
console to be selected. It turns out that the add_preferred_console was
being called after the hvc_console driver was registered. It only works
when it is called before the console driver is registered.
Reorder hvc_console.o after the hvc_console drivers to allow the selection
during console_initcall processing.

Apply some alterations to the memory barrier document that I worked out
with Paul McKenney of IBM, plus some of the alterations suggested by Alan
Stern.
The following changes were made:
(*) One of the examples given for what can happen with overlapping memory
barriers was wrong.
(*) The description of general memory barriers said that a general barrier is
a combination of a read barrier and a write barrier. This isn't entirely
true: it implies both, but is more than a combination of both.
(*) The first example in the "SMP Barrier Pairing" section was wrong: the
loads around the read barrier need to touch the memory locations in the
opposite order to the stores around the write barrier.
(*) Added a note to make explicit that the loads should be in reverse order to
the stores.
(*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences"
section to make them clearer. Added a couple of diagrams to make it more
clear as to how it could go wrong without the barrier.
(*) Added a section on memory speculation.
(*) Dropped any references to memory allocation routines doing memory
barriers. They may do sometimes, but it can't be relied on. This may be
worthy of further documentation later.
(*) Made the fact that a LOCK followed by an UNLOCK should not be considered a
full memory barrier more explicit and gave an example.

HighPoint RocketRAID 3220/3320 series 8 channel PCI-X SATA RAID Host
Adapters.
Fixes from original submission:
Merge Andrew Morton's patches:
- Provide locking for global list
- Fix debug printks
- uninline function with multiple callsites
- coding style fixups
- remove unneeded casts of void*
- kfree(NULL) is legal
- Don't "succeed" if register_chrdev() failed - otherwise we'll later
unregister a not-registered chrdev.
- Don't return from hptiop_do_ioctl() with the spinlock held.
- uninline __hpt_do_ioctl()
Update for Arjan van de Ven's comments:
- put all asm/ includes after the linux/ ones
- replace mdelay with msleep
- add pci posting flush
- do not set pci command reqister in map_pci_bar
- do not try merging sg elements in hptiop_buildsgl()
- remove unused outstandingcommands member from hba structure
- remove unimplemented hptiop_abort() handler
- remove typedef u32 hpt_id_t

Doing PCI config space accesses to non-present PCI slots
can result in fatal JBUS errors if the PCI config access
hypervisor call is performed on cpus other than the boot
cpu.
PCI config space accesses to present PCI slots works just
fine.
Recursively traverse the OBP device tree under the PCI
controller node and record all present device IDs into
a small hash table.
Avoid the hypervisor call for any PCI config space access
attempt for a device not recorded in the hash table.

Get rid of all the SUN_570X logic and instead:
1) Make sure MEMARB_ENABLE is set when we probe the SRAM
for config information. If that is off we will get
timeouts.
2) Always try to sync with the firmware, if there is no
firmware running do not treat it as an error and instead
just report it the first time we notice this condition.
3) If there is no valid SRAM signature, assume the device
is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT.
Update driver version and release date.

transaction within each such operation may involve multiple locking of AGF
buffer. While the freeing extent function has sorted the extents based on
AGF number before entering into transaction, however, when the file system
space is very limited, the allocation of space would try every AGF to get
space allocated, this could potentially cause out-of-order locking, thus
deadlock could happen. This fix mitigates the scarce space for allocation
by setting aside a few blocks without reservation, and avoid deadlock by
maintaining ascending order of AGF locking.
