The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.
arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.
With this change in place this code should be useable by all platforms
except those that won't let the OS touch the hardware like ppc RTAS.

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c. Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.
So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.
The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.

With the removal of msi_lookup_irq all of the functions using msi_lock
operated on a single device and none of them could reasonably be
called on that device at the same time.
Since what little synchronization that needs to happen needs to happen
outside of the msi functions, msi_lock could never be contended and as
such is useless and just complicates the code.

The function msi_lookup_irq was horrible. As a side effect of running
it changed dev->irq, and then the callers would need to change it
back. In addition it does a global scan through all of the irqs,
which seems to be the sole justification of the msi_lock.
To remove the neede for msi_lookup_irq I added first_msi_irq to struct
pci_dev. Then depending on the context I replaced msi_lookup_irq with
dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled.
msi_enabled and msix_enabled were already present in pci_dev for other
reasons.

The PCI save/restore code doesn't need to care about MSI vs MSI-X, all
it really wants is to say "save/restore all MSI(-X) info for this device".
This is borne out in the code, we call the MSI and MSI-X save routines
side by side, and similarly with the restore routines.
So combine the MSI/MSI-X routines into pci_save_msi_state() and
pci_restore_msi_state(). It is up to those routines to decide what state
needs to be saved.

At least the Keyspan USA-19HS USB-to-serial converter supports
two different configurations, one where the input endpoints
have interrupt transfer type and one where they are bulk endpoints.
The default UHCI configuration uses the interrupt input endpoints.
The keyspan driver, OTOH, assumes that the device has only bulk
endpoints (all URBs are initialized by calling usb_fill_bulk_urb
in keyspan.c/ keyspan_setup_urb). This causes the interval field
of the input URBs to have a value of zero instead of one, which
'accidentally' worked with Linux at least up to 2.6.17.11 but
stopped to with 2.6.18, which changed the UHCI support code handling
URBs for interrupt endpoints. The patch below modifies to driver to
initialize its input URBs either as interrupt or as bulk URBs,
depending on the transfertype contained in the associated endpoint
descriptor (only tested with the default configuration) enabling
the driver to again receive data from the serial converter.

This patch (as710) adds a sysfs class-device attribute file named
"companion" for EHCI controllers. The file contains a list of port
numbers that are dedicated to the companion controller; by writing a
port number to the file the user can force a high-speed device

know it is not possible to do this for a device attached to an
external hub.) A port is removed from the file by writing the
negative of its port number.
Several users have asked for this facility and it seems like a useful
thing to have. Every now and then one runs across a device which

This patch adds a new, "binary" API in addition to the old, text API usbmon
had before. The new API allows for less CPU use, and it allows to capture
all data from a packet where old API only captured 32 bytes at most. There
are some limitations and conditions to this, e.g. in case someone constructs
a URB with 1GB of data, it's not likely to be captured, because even the
huge buffers of the new reader are finite. Nonetheless, I expect this new
capability to capture all data for all real life scenarios.
The downside is, a special user mode application is required where cat(1)
worked before. I have sample code at http://people.redhat.com/zaitcev/linux/

Windows Mobile 5 based devices described as supporting "ActiveSync":
- Speak RNDIS but lack the CDC and union descriptors. This patch
updates the cdc ethernet code to fake ACM descriptors we need.
- Require RNDIS_MSG_QUERY messages to include a buffer of the size the
response should generate. This patch updates the rndis host code to
pass this will-be-ignored data.
The resulting RNDIS host code has been reported to work with several
WM5 based devices.
(Note that a fancier patch is available at synce.sf.net.)
Some bugfixes, affecting not just ActiveSync:
(a) when cleaning up after RNDS init fails, scrub the second interface
just like cdc_ether does, so disconnect won't oops.
(b) handle peripherals that use the pad-to-end-of-packet option; some
devices can't talk to us if that option doesn't work.
(c) when choosing configurations, don't forget about an RNDIS config
just because the RNDIS driver is dynamically linked.

It turns out that minor tweaks to the "CDC Subset" support in the Ethernet
gadget driver, just updating a config descriptor, let it be automagically
recognized by a Windows driver supported by MCCI.
This patch adds those descriptors, so systems using PXA 255 processors
(like Gumstix etc) can interop with those commercial MS-Windows drivers.
This is a Good Thing since Microsoft's RNDIS code has bugginess issues,
which are unfortunately compounded by "won't fix" issues as well as "the
published specs are incomplete and wrong" issues. Being able to talk to
the MCCI driver gives Windows users another connectivity option. (MCCI

This patch implements ACPI integration for generic IDE devices.
The ACPI spec mandates that some methods are called during suspend and
resume. And consequently there most modern Laptops cannot resume
properly without it.
According to the spec, we should call '_GTM' (Get Timing) upon suspend
to store the current IDE adapter settings.
Upon resume we should call '_STM' (Set Timing) to initialize the
adapter with the stored settings; afterwards '_GTF' (Get Taskfile)
should be called which returns a buffer with some IDE initialisation
commands. Those commands should be passed to the drive.
There are two module params which control the behaviour of this patch:
'ide=noacpi'
Do not call any ACPI methods (Disables any ACPI method calls)
'ide=acpigtf'
Enable execution of _GTF methods upon resume.
Has no effect if 'ide=noacpi' is set.
'ide=acpionboot'
Enable execution of ACPI methods during boot.
This might be required on some machines if 'ide=acpigtf' is
selected as some machines modify the _GTF information
depending on the drive identification passed down with _STM.

Bart, here's a driver I've been keeping out-of-tree for the past couple
of years. This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE
CompactFlash adapter card.
It's probably way out of sync with the latest driver model (??), but it
still builds/works. I'm not interested in doing much of a rewrite, other
than for libata someday, as I no longer use the card myself.
But lots of other people do seem to use it, so it might be nice to see it

This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller,
completely reworked from the original brain-damaged Toshiba's 2.4 version.
This single channel UltraDMA/66 controller is very simple in programming,
yet Toshiba managed to plant many interesting bugs in it. The particularly
nasty "limitation 5" (as they call the errata) caused me to abuse the IDE
core in a possibly most interesting way so far. However, this is still
better than the #ifdef mess in drivers/ide/ide-io.c that the original

Remove the following useless fragments from the driver:
- the ide_dma_lostirq() and ide_dma_timeout() handlers which boil down to just
printing the incoherent reset message and calling their default counterparts;
- check for non-NULL drive->id in the ide_dma_check() handler -- this is assumed
to be true by all other handlers (also, get rid of unnecessary nesting of the
conditional statements there);
- the comment before pdcnew_tune_drive() which has nothing to do with the code.

Fix/cleanup the driver's tuneproc() and ratemask() methods:
- PPE, IE, and TIME bits need to be cleared beforehand for the slave drive as
well as master (Alan probably just forgot about it);
- this driver only supports PIO modes up to 4, so must pass the correct limit
to ide_get_best_pio_mode();
- use min_t() macro instead of min();
- simplify slave vs master drive evaluation;
- do come coding and formatting cleanups...

According to the datasheet, Intel 82371MX (MPIIX) actually has only a
single IDE channel mapped to the primary or secondary ports depending on
the value of the bit 14 of the IDETIM register at PCI config. offset 0x6C
(the register at 0x6F which the driver refers to. doesn't exist). So,
disguise the controller as dual channel and set enablebits masks/values
such that only either primary or secondary channel is detected enabled.
Also, preclude the IDE probing code from reading PCI BARs, this controller
just doesn't have them (it's not the separate PCI function like the other
PCI controllers), it only decodes the legacy addresses.
[ Alan sayeth " MPIIX does not work with or without the change. It needs its
own different driver and not to use setup-pci. Huge job and since it works
well with libata who cares. Ditto the early PIIX chip." ]

Fix minor coding mistake in the HPT36x PCI clock detection code noticed by
Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing
'break' statements. This, however, most probably never mattered -- in fact, I
was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes
didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e.
supported only 33 MHz PCI.
Note that in the original driver there was another bug: 25 and 40 MHz cases
were interchanged. Since the 'cmd_high_time' field is in units of PCI clocks,
a lower clock count just *cannot* correspond to a higher frequency, i. e. it
should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

Finally, rework the driver init. code to correctly handle all the chip
variants HighPoint has created so far. This should cure the rest of the
timing issues in the driver (especially, on 66 MHz PCI) caused by the
HighPoint's habit of switching the base DPLL clock with every new revision
of the chips...
- switch to using the enumeration type to differ between the numerous chip
variants, matching PCI device/revision ID with the chip type early, at the
init_setup stage;
- extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
stop duplicating it for each channel by storing the pointer in the pci_dev
structure: first, at the init_setup stage, point it to a static "template"
with only the chip type and its specific base DPLL frequency, the highest
supported DMA mode, and the chip settings table pointer filled, then, at
the init_chipset stage, allocate per-chip instance and fill it with the
rest of the necessary information;
- get rid of the constant thresholds in the HPT37x PCI clock detection code,
switch to calculating PCI clock frequency based on the chip's base DPLL
frequency;
- switch to using the DPLL clock and enable UltraATA/133 mode by default on
anything newer than HPT370/A;
- fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
unify the HPT36x/37x setup code and the speedproc handlers by joining the
register setting lists into the table indexed by the clock selected;
- add enablebits for all the chips to avoid touching disabled channels
(though the HighPoint BIOS seem to only disable the primary one on
HPT371/N);
- separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
when setting an UltraDMA mode in hpt37x_tune_chipset().
This version has been tested on HPT370/302/371N.
Thanks to Alan for the inspiration. Hopefully, his libata driver will also
benefit from the work done on this "obsolete" driver...

Clean up DMA timeout handling for HPT370:
- hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end()
called afterwards return the incorrect result, and the DMA engine was reset
both before and after stopping DMA while the HighPoint drivers only do it
after (which seems logical) -- fix this and also rename the function;
- get rid of the needless mutual recursion in hpt370_ide_dma_end() and
hpt370_ide_dma_timeout();
- get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from
the driver's interrupt handler later does all its work.

Continue with the driver rewrite:
- move the interrupt twiddling code from the speedproc handlers into the
init_hwif_hpt366 which allows to merge the two HPT37x speedproc handlers
into one;
- get rid of in init_hpt366 which solely consists of the duplicate code, then
fold init_hpt37x() into init_chipset_hpt366();
- fix hpt3xx_tune_drive() to always set the PIO mode requested, not the best
possible one, change hpt366_config_drive_xfer_rate() accordingly, simplify
it a bit;
- group all the DMA related code together init_hwif_hpt366(), and generally
clean up and beautify it.

- only touch the relevant MCR when detecting the cable type on HPT374's
function 1;
- make HPT36x's speedproc handler look the same way as HPT37x ones; fix the
PIO timing register mask for HPT37x.
- rename all the HPT3xx register related variables consistently; clean up the
whitespace.

bad Ultra33 drive list lookups anymore; remove the duplicate code from
the latter function. Move the quirky drive list lookup into
hpt3xx_quirkproc() where it should have been from the start...
- Disable UltraATA/100 for HPT370 by default as the 33 MHz ATA clock
being used does not allow for it, and this *greatly* increases the
transfer speed.
- Save some space by using byte-wide fields in struct hpt_info; switch to
reading the 8-bit PCI revision ID reg. only, not the whole 32-bit reg.
- Start incrementing the driver version number with each patch (should
have been done from the first one posted).
