Fix up an off by one error in calculating retries for scsi

was sent to scsi core with retries = 0, causing the overall

Current fc_transport consumers initially register rports
with an UNKNOWN role-state and follow-up with a call to
fc_remote_port_rolechg(). Modify code in
fc_remote_port_add() to scan the fc_host_rport_bindings()
array for consistent bindings regardless of role-type.
Original code would only scan bindings array for targets,
causing duplicate fc_remote_ports/rport-X:Y-Z entries to be
created for the yet-to-be-role-changed rports.

Remove a hack in the sg driver that alters the total buffer
length for SG_IO commands to ensure buffers are not odd byte
lengths. This breaks on the ipr driver since it requires the
request_bufflen to equal the length specified in the cdb.
The block layer SG_IO code does not appear to have this hack.

These messages end up polluting logs when things like NetworkManager or
wpa_supplicant are controlling the driver. They aren't really that
useful, and no other drivers output messages like this when the user
fiddles with encryption keys. Users can use iwconfig and other
wireless-tools methods to determine and change the current transmit key
if they wish to do so manually. Therefore, remove the messages.

- check that the device is up before it is enabled again;
- the descriptor ring indexes must be set to zero before
cp_init_hw() is issued. Add a nice comment to remember

velocity_rx_refill() only replenishes the descriptor entries which
belong to the CPU. It works great in the Rx path but the driver must
ensure that all the descriptors are freed before velocity_rx_refill()
is used in velocity_change_mtu(). The patch resets the Rx descriptors
in velocity_free_rd_ring().

Some Sun parts don't have PCI_VENDOR_ID_SUN in the subsystem

Further investigation shows that the problem was introduced during

ACPI is initialized very early on x86-64, before the DMI code is
initialized. This means it would often discover a 0 year and then turn
off ACPI because it thought the BIOS was too old. Some systems don't
boot without ACPI so this was a problem.
I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged. For 2.6.16 let's just turn the
check off. It never made much sense anyways because there are no x86-64
systems older than 2002 or so and they generally all have working ACPI.

This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi
And since PM timer is needed for correct timing on a lot of systems
now (e.g. AMD dual cores) and we often get bug reports from people
who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had
this change before and it's a good thing.
I also fixed the description slightly to make this more clear.

Silicon Image has disclosed a new sil3114/3152 errata and workaround
which causes the controller to return R_ERR on DMA activate FIS if the
FIS is received while the next PRD is being fetched. This patch
implements the workaround.
This errata results in lock up and doesn't trigger if m15w workaround
is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1
which makes 3512/3114 lock up with some drives on all kernel versions
since 2.6.14-rc1 upto now (2.6.16-rc4). This patch should fix the
regression.

EGA boards suck: they mostly have write-only registers. This is
particularly problematic for the overflow register: for being able to write
to it, we would have to handle vertical sync & such too, which (I'd say)
would potentially break a lot of configurations. Instead, just disabling
vertical resize for EGA boards is just nice enough (horizontal resize still
works).

tty_schedule_flip() would schedule a thread that would call flush_to_ldisc().
If tty_buffer_request_room() gets called prior to that thread running --
which is likely in this loop in hvc_poll(), it would set the active flag
in the tty buffer and consequently flush_to_ldisc() would ignore it.
The result is that input on the hvc console is not processed.
This fix calls tty_flip_buffer_push (and flags the tty as
"low_latency"). The push to the ldisc thus happens synchronously.
