Dave Müller sent a diff for the pata_oldpiix that highlighted a problem
where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while
the core code uses 0xFF.
This turns out to have other consequences such as code doing >= XFER_UDMA_0
also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect
set_dma_mode, although some drivers call back into their own set mode code
from other points.
Having been through the drivers I've added helpers for using_udma/using_mwdma
dma_enabled so that people don't open code ranges that may change (eg if UDMA8
appears somewhere)
Thanks to David for the initial bits

SIS controllers were blacklisted for PMP as enabling it made device
detection fail whether the device was PMP or not - the natural
conclusion was the controller chokes on SRST w/ pmp==15. However, it
turned out that the controller just didn't like issuing SRST after
hardreset w/o clearing SError first. Interestingly, the SRST itself
succeeds but the following commands fail.
If SError is cleared between hardreset and SRST, which is the default
behavior now, everything works fine and SIS controllers work with PMPs
happily.
Remove PMP blacklisting for SIS AHCIs.

Commit bfce5e0179ad059035df28558724ff60af708e09 implemented custom
tf_load for pata_via. This patch cleans it up a bit.
* Instead of duplicating whole body, copy tf and set ATA_TFLAG_DEVICE
when necessary.
* Rename via_ata_tf_load() to via_tf_load().
* No need to set .tf_load in via_port_ops_noirq as it inherits from
via_port_ops.
* Clean up indentation.

Save SControl during probing and restore it on detach. This prevents
adjustments made by libata drivers to seep into the next driver which
gets attached (be it a libata one or not).
It's not clear whether SControl also needs to be restored on suspend.
The next system to have control (ACPI or kexec'd kernel) would
probably like to see the original SControl value but there's no
guarantee that a link is gonna keep working after SControl is adjusted
without a reset and adding a reset and modified recovery cycle soley
for this is an overkill. For now, do it only for detach.

As an optimization, follow-up SRST used to be skipped if
classification wasn't requested even when hardreset requested it via
-EAGAIN. However, some hardresets can't wait for device readiness and
skipping SRST can cause timeout or other failures during revalidation.
Always perform follow-up SRST if hardreset returns -EAGAIN. This
makes reset paths more predictable and thus less error-prone.
While at it, move hardreset error checking such that it's done right
after hardreset is finished. This simplifies followup SRST condition
check a bit and makes the reset path easier to modify.

While I don't have a hotplug capable system at hand, I think two issues need
fixing:
- pud_phys (in kernel_physical_ampping_init()) would remain uninitialized in
the after_bootmem case
- the locking done just around phys_pmd_{init,update}() would leave out pgd
updates, and it was needlessly covering code portions that do allocations
(perhaps using a more friendly gfp value in alloc_low_page() would then be
possible)

Joshua Hoblitt reported that only 3 GB of his 16 GB of RAM is

Alex Chiang and Matthew Wilcox pointed out that pci_get_dev_by_id() does
not properly decrement the reference on the from pointer if it is
present, like the documentation for the function states it will.
It fixes a pretty bad leak in the hotplug core (we were leaking an
entire struct pci_dev for each function of each offlined card, the first
time around; subsequent onlines/offlines were ok).

Commit ef0ff95f136f0f2d035667af5d18b824609de320 (shpchp: fix slot name)
introduces the shpchp_slot_with_bus module parameter, which was intended
to help work around broken firmware that assigns the same name to multiple
slots.
Commit b3bd307c628af2f0a581c42d5d7e4bcdbbf64b6a (shpchp: add message about
shpchp_slot_with_bus option) tells the user to use the above parameter
in the event of a name collision.
This approach is sub-optimal because it requires too much work from
the user.
Instead, let's rename the slot on behalf of the user. If firmware
assigns the name N to multiple slots, then:
The first registered slot is assigned N
The second registered slot is assigned N-1
The third registered slot is assigned N-2
The Mth registered slot becomes N-M
In the event we overflow the slot->name parameter, we report an
error to the user.
This is a temporary fix until the entire PCI core can be reworked
such that individual drivers no longer have to manage their own
slot names.

Calling a ccw driver's notify function without the ccw device lock
held opens up a race window between discovery and handling of a change
in the device operational state. As a result, the device driver may

Remove race by extending the ccw device lock from state change
discovery to the calling of the notify function.

The Perform Subsystem Function/Prepare for Read Subsystem Data
command requires 12 bytes of parameter data, but the respective data
structure dasd_psf_prssd_data has a length of 16 bytes.
Current storage servers ignore the obsolete bytes, but older models
fail to execute the command and report an incorrect length error.
This causes the device initilization for these devices to fail.
To fix this problem we need to correct the dasd_psf_prssd_data
structure and shorten it to the correct length.

ext4 does not work on s390 because ext2_find_next_bit is broken. Fortunately
this function is only used by ext4. The function uses ffs which does not work
analog to ffz. The result of ffs has an offset of 1 which is not taken into
account. To fix this use the low level __ffs_word function directly instead
of the ill defined ffs.
In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit
by passing the bit offset into __ffz_word instead of adding it after the
function call returned.

This patch (as1069c) changes the way OHCI root-hub status-change
interrupts are enabled. Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub. This approach turns out to be subject to races, resulting
in unnecessary polling.
The patch does away with the method entirely. Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present. This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

This patch (as1130) fixes an incompatibility between the new PM
infrastructure and USB power management. We are not allowed to call
drivers' probe routines during a system sleep transition between the
"prepare" and "complete" callbacks, but that's exactly what we do when
a driver doesn't have full suspend/resume support. Such drivers are
unbound during the "suspend" call and reprobed during the "resume" call.
The patch causes the reprobe step to be skipped if the "complete"
callback hasn't been issued yet, i.e., if the interface's
dev.power.status field is not equal to DPM_ON. Thus during the
"resume" callback nothing bad will happen, and during the final
"complete" callback the reprobing will occur as desired.
This fixes the problem reported in Bugzilla #11263.

This patch (as1129) adds support for the new PM callbacks to usbcore.
The new callbacks merely invoke the same old USB power management
routines as the old ones did.
A minor improvement is that the callbacks are present only in the
"USB-device" device_type structure, rather than in the bus_type
structure. This way they will be invoked only for USB devices, not
for USB interfaces. The core USB PM routines automatically handle
suspending and resuming interfaces along with their devices.

This patch (as1128) fixes one of the problems related to the new PM
infrastructure. We are not allowed to register new child devices
during the middle of a system sleep transition, but unbinding a USB
driver causes the core to automatically install altsetting 0 and
thereby create new endpoint pseudo-devices.
The patch fixes this problem (and the related problem that installing
altsetting 0 will fail if the device is suspended) by deferring the
Set-Interface call until some later time when it is legal and can
succeed. Possible later times are: when a new driver is being probed
for the interface, and when the interface is being resumed.

This patch (as1127) makes a minor change to the prototypes of the
usb_suspend_interface() and usb_resume_interface() routines. Now the

It makes the code look simpler, even if it really isn't much different
from before.

If Indexed Mode register accesses are enabled, the ep0_rxstate()
function calls musb_g_ep0_giveback() before writing to the CSR
register. When control returns to this ep0_rxstate, the index
register contents are over-written. This causes the CSR register
write to fail.
Fixed by writing the correct value into the index register before
writing to the CSR.
This was observed only in ep0_rxstate() with g_ether loaded and
the device connected to a MS Windows host PC. Anticipatively fixed
ep0_txstate() as well.

We can change debugging level on the fly via
/sys/module/musb_hdrc/parameters/debug.
We can also get rid of the LOGLEVEL facility in Kconfig
and rely only in module parameter.

Drivers should not add procfs. The functionality in the old
procfs file will be moved to debugfs.

The new composite framework revealed a weakness in the
pxa27x_udc driver gadget register function. Instead of
checking if speed asked for was USB_LOW_SPEED upon
usb_gadget_register() to deny service, it checked only
for USB_FULL_SPEED, thus denying service to usb high
speed capable gadgets (like g_ether).

This patch gets my Rosewill RNX-56USB USB modem (with Conexant CX93010
chipset) up and running to the point where I can send AT commands and
retrieve caller ID data, which is all I want to do with it.
