libata: separate out ata_host_alloc() and ata_host_register()
Reorganize ata_host_alloc() and its subroutines into the following
three functions.
* ata_host_alloc() : allocates host and its ports. shost is not
registered automatically.
* ata_scsi_add_hosts() : allocates and adds shosts associated with an
ATA host. Used by ata_host_register().
* ata_host_register() : takes a fully initialized ata_host structure
and registers it to libata layer and probes it.
Only ata_host_alloc() and ata_host_register() are exported.
ata_device_add() is rewritten using the above functions. This patch
does not introduce any observable behavior change. Things worth
mentioning.
* print_id is assigned at registration time and LLDs are allowed to
overallocate ports and reduce host->n_ports during initialization.
ata_host_register() will throw away unused ports automatically.
* All SCSI host initialization stuff now resides in
ata_scsi_add_hosts() in libata-scsi.c, where it should be.
* ipr is now the only user of ata_host_init(). Either kill it by
converting ipr to use ata_host_alloc() and friends or rename and
move it to libata-scsi.c

Don't embed ap inside shost. Allocate it separately and point it back
from shosts's hostdata. This makes port allocation more flexible and
allows regular ATA and SAS share host alloc/init paths.

libata: improve AC_ERR_DEV handling for ->post_internal_cmd
->post_internal_cmd is simplified EH for internal commands. Its
primary mission is to stop the controller such that no rogue memory
access or other activities occur after the internal command is
released. It may provide error diagnostics by setting qc->err_mask
but this hasn't been a requirement.
To ignore SETXFER failure for CFA devices, libata needs to know
whether a command was failed by the device or for any other reason.
ie. internal command needs to get AC_ERR_DEV right.
This patch makes the following changes to AC_ERR_DEV handling and
->post_internal_cmd semantics to accomodate this need and simplify
callback implementation.
1. As long as the correct bits in the result TF registers are set,
there is no need to set AC_ERR_DEV explicitly. libata EH core
takes care of that for both normal and internal commands.
2. The only requirement for ->post_internal_cmd() is to put the
controller into quiescent state. It needs not to set any err_mask.
3. ata_exec_internal_sg() performs minimal error analysis such that
AC_ERR_DEV is automatically set as long as result_tf is filled
correctly.

ahci: implement ata_save/restore_initial_config()
There are several registers which describe how the controller is
configured. These registers are sometimes implemented as r/w
registers which are configured by firmware and get cleared on
controller reset or after suspend/resume cycle. ahci saved and
restored those values inside ahci_reset_controller() which is a bit
messy and doesn't work over suspend/resume cycle.
This patch implements ahci_save/restore_initial_config(). The save
function is called during driver initialization and saves cap and
port_map to hpriv. The restore function is called after the
controller is reset to restore the initial values.
Sometimes the initial firmware values are inconsistent and need to be
fixed up. This is handled by ahci_save_initial_config(). For this,
there are two versions of saved registers. One to write back to the
hardware register, the other to use during driver operation. This is
necessary to keep ahci's behavior unchanged (write back fixed up
port_map while keeping cap as-is).
This patch makes ahci save the register values once before the first
controller reset, not after it's been reset. Also, the same stored
values are used written back after each reset, so the register values
are properly recovered after suspend/resume cycle.

a procedure with the common code, and a procedure with

libata/IDE: remove combined mode quirk

This eliminates the awful, low-performing split-driver configuration

and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.
For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers

In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

libata: cable detection fixes
2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.
Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the rest of the needed changes.
We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.
This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.
If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.

them but other follow up patches will (ie Adrian please don't submit

that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame. The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring. So if you receive frames fast enough the skb being processed by
the network stack can get corrupted. The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP. I'll post test results when I hear

USB: add Freescale high-speed USB SOC device controller driver
Freescale high-speed USB SOC can be found on some Freescale processors
among different architectures. It supports both host and device functions.
This driver adds its device support for Linux USB Gadget layer.
It is tested on MPC8349 and MPC8313, but should work on other platforms
with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note
that this driver doesn't yet include OTG support.

USB: iowarrior.c: timeouts too small in usb_control_msg calls
The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.
The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.
The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

USB: Remove Huawei unusual_devs entry
Per the Rui Santos and the hardware manufacturers, this actually inhibits
useful parts of the hardware. The correct way to use this hardware is with the
software at http://www.kanoistika.sk/bobovsky/archiv/umts/ and the manufacturers
are also planning on including Linux drivers/material in future revisions.
I have found that /drivers/usb/misc/ldusb.c works with the "PICDEM Full

USB: remove ancient/broken CRIS hcd
Remove the old crisv10 HCD ... it can't have built for some time,
doesn't even have a Kconfig entry, was the last driver not to have
been converted to the "hcd" framework, and considering the usbcore
changes since its last patch was merged, has just got to buggy as
all get-out.
I'm told Axis has a new driver, and will be submitting it soon.

usb ethernet gadget, workaround network stack API glitch
Another workaround for the glitch in the network layer, whereby one call
ignores the (otherwise kernel-wide) convention that free() calls should
not oops when passed nulls. This code already handles that API glitch in
most other paths.

USB: cxacru: ADSL state management
The device has commands to start/stop the ADSL function, so this adds a
sysfs attribute to allow it to be started/stopped/restarted. It also stops
polling the device for status when the ADSL function is disabled.
There are no problems with sending multiple start or stop commands, even
with a fast loop of them the device still works. There is no need to
protect the restart process from further user actions while it's waiting
for 1.5s.
