USB: fix build error when CONFIG_PM_SLEEP isn't enabled
This patch fixes a build error that occurs when CONFIG_PM is enabled
and CONFIG_PM_SLEEP isn't:
>> drivers/usb/host/ohci-pci.c:294:10: error: 'usb_hcd_pci_pm_ops' undeclared here (not in a function)
.pm = &usb_hcd_pci_pm_ops
Since the usb_hcd_pci_pm_ops structure is defined and used when
CONFIG_PM is enabled, its declaration should not be protected by
CONFIG_PM_SLEEP.

usb: musb: am335x-evm: Do not remove the session bit HOST-only mode
This is what I observe:
On the first connect, the musb starts with DEVCTL.Session set. On
disconnect, musb_core calls try_idle. That functions removes the Session
bit signalizing that the session is over (something that only in OTG is
required). A new device, that is plugged, is no longer recognized.
I've setup a timer and checked the DEVCTL register and I haven't seen a
change in VBus and I saw the B-Device bit set. After setting the IDDIG
into A mode and forcing the device to behave like a A device, I didn't
see a change.
Neither VBUS goes to 0b11 nor does a session start request comes.
In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the
OTG_STATE_A_WAIT_BCON state while not in OTG mode.
Since the second port hast a standard A plug the patch changes the port
to run in host mode only and skips the timer which would remove
DEVCTL.Session so we can reconnect to another device later.

usb: gadget: configfs: keep a function if it is not successfully added
If usb_add_function() fails then the currently processed function
is already not in the list in struct config_usb_cfg, and neither is it
in the list in struct usb_configuration. At the err_purge_funcs label the
purge_config_funcs() is called, which iterates over all configurations,
and in each configuration it iterates over all _successfully_ added
functions, and moves them back from the list in struct usb_configuration
to the list in struct config_usb_cfg. BUT the function which has just
failed adding and caused the unwind process is not taken care of and
is effectively lost.
This patch modifies the configfs_composite_bind() function so that if
the usb_add_function() fails, then the currently processed function
is returned to the list in struct config_usb_cfg.
It would be tempting to delay the list_del() in question after
usb_add_function() invocation, but a struct list_head (&f->list) cannot be
stored in more than one list at the same time, so the list_del() must
be called before usb_add_function(). Hence, the solution is to list_add()
after usb_add_function() in case of error.

xhci: Step 2 to fix usb-linus and usb-next.
Hi Greg,
This is the first of two steps to fix your usb-linus and usb-next trees.
As I mentioned, commit
4fae6f0fa86f92e6bc7429371b1e177ad0aaac66 "USB:
handle LPM errors during device suspend correctly" was incorrectly added
to usb-next when it should have been added to usb-linus and marked for
stable.
Two port power off bug fixes touch the same code that patch touches, but
it's not easy to simply move commit
4fae6f0f patch to usb-linus because
commit
28e861658e23ca94692f98e245d254c75c8088a7 "USB: refactor code for
enabling/disabling remote wakeup" also touched those code sections.
I propose a two step process to fix this:
1. Pull these four patches into usb-linus.
2. Revert commit
28e861658e23ca94692f98e245d254c75c8088a7 from usb-next.
Merge usb-linus into usb-next, and resolve the conflicts.
I will be sending pull requests for these steps.
This pull request is step two.

Fix TLB gather virtual address range invalidation corner cases
Ben Tebulin reported:
"Since v3.7.2 on two independent machines a very specific Git
repository fails in 9/10 cases on git-fsck due to an SHA1/memory
failures. This only occurs on a very specific repository and can be
reproduced stably on two independent laptops. Git mailing list ran
out of ideas and for me this looks like some very exotic kernel issue"
and bisected the failure to the backport of commit
53a59fc67f97 ("mm:
limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT").
That commit itself is not actually buggy, but what it does is to make it
much more likely to hit the partial TLB invalidation case, since it
introduces a new case in tlb_next_batch() that previously only ever
happened when running out of memory.
The real bug is that the TLB gather virtual memory range setup is subtly
buggered. It was introduced in commit
597e1c3580b7 ("mm/mmu_gather:
enable tlb flush range in generic mmu_gather"), and the range handling
was already fixed at least once in commit
e6c495a96ce0 ("mm: fix the TLB
range flushed when __tlb_remove_page() runs out of slots"), but that fix
was not complete.
The problem with the TLB gather virtual address range is that it isn't
set up by the initial tlb_gather_mmu() initialization (which didn't get
the TLB range information), but it is set up ad-hoc later by the
functions that actually flush the TLB. And so any such case that forgot
to update the TLB range entries would potentially miss TLB invalidates.
Rather than try to figure out exactly which particular ad-hoc range
setup was missing (I personally suspect it's the hugetlb case in
zap_huge_pmd(), which didn't have the same logic as zap_pte_range()
did), this patch just gets rid of the problem at the source: make the
TLB range information available to tlb_gather_mmu(), and initialize it
when initializing all the other tlb gather fields.
This makes the patch larger, but conceptually much simpler. And the end
result is much more understandable; even if you want to play games with
partial ranges when invalidating the TLB contents in chunks, now the
range information is always there, and anybody who doesn't want to
bother with it won't introduce subtle bugs.
Ben verified that this fixes his problem.

This is the first of three steps to fix your usb-linus and usb-next

for stable.
Two port power off bug fixes touch the same code that patch touches, but
it's not easy to simply move commit
4fae6f0f patch to usb-linus because
commit
28e861658e23ca94692f98e245d254c75c8088a7 "USB: refactor code for

1. Pull these four patches into usb-linus.
2. Revert commit

xhci-plat: Don't enable legacy PCI interrupts.
The xHCI platform driver calls into usb_add_hcd to register the irq for
its platform device. It does not want the xHCI generic driver to
register an interrupt for it at all. The original code did that by
setting the XHCI_BROKEN_MSI quirk, which tells the xHCI driver to not
enable MSI or MSI-X for a PCI host.
Unfortunately, if CONFIG_PCI is enabled, and CONFIG_USB_DW3 is enabled,
the xHCI generic driver will attempt to register a legacy PCI interrupt
for the xHCI platform device in xhci_try_enable_msi(). This will result
in a bogus irq being registered, since the underlying device is a
platform_device, not a pci_device, and thus the pci_device->irq pointer
will be bogus.
Add a new quirk, XHCI_PLAT, so that the xHCI generic driver can
distinguish between a PCI device that can't handle MSI or MSI-X, and a
platform device that should not have its interrupts touched at all.
This quirk may be useful in the future, in case other corner cases like
this arise.

usb: Don't fail port power resume on device disconnect.
Userspace can tell the kernel to power off any USB port, including ones
that are visible and connectible to users. When an attached USB device
goes into suspend, the port will be powered off if the
pm_qos_no_port_poweroff file for its port is set to 0, the device does
not have remote wakeup enabled, and the device is marked as persistent.
If the user disconnects the USB device while the port is powered off,
the current code does not handle that properly. If you disconnect a
device, and then run `lsusb -v -s` for the device, the device disconnect
does not get handled by the USB core. The runtime resume of the port
fails, because hub_port_debounce_be_connected() returns -ETIMEDOUT.
This means the port resume fails and khubd doesn't handle the USB device
disconnect. This leaves the device listed in lsusb, and the port's
runtime_status will be permanently marked as "error".
Fix this by ignoring the return value of hub_port_debounce_be_connected.
Users can disconnect USB devices while the ports are powered off, and we
must be able to handle that.

net_sched: restore "linklayer atm" handling
commit
56b765b79 ("htb: improved accuracy at high rates")

tc class add ... htb rate X ceil Y linklayer atm
The linklayer setting is implemented by modifying the rate table
which is send to the kernel. No direct parameter were
transferred to the kernel indicating the linklayer setting.
The commit
56b765b79 ("htb: improved accuracy at high rates")
removed the use of the rate table system.
To keep compatible with older iproute2 utils, this patch detects
the linklayer by parsing the rate table. It also supports future
versions of iproute2 to send this linklayer parameter to the
kernel directly. This is done by using the __reserved field in
struct tc_ratespec, to convey the choosen linklayer option, but
only using the lower 4 bits of this field.
Linklayer detection is limited to speeds below 100Mbit/s, because
at high rates the rtab is gets too inaccurate, so bad that
several fields contain the same values, this resembling the ATM
detect. Fields even start to contain "0" time to send, e.g. at
1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have
been more broken than we first realized.

drivers/net/ethernet/via/via-velocity.c: update napi implementation
Drivers supporting NAPI should use a NAPI-specific function for receiving
packets. Hence netif_rx is changed to netif_receive_skb.
Furthermore netif_napi_del should be used in the probe and remove function
to clean up the NAPI resource information.
Thanks to Francois Romieu, David Shwatrz and Rami Rosen for their help on
this patch.

Revert "cxgb3: Check and handle the dma mapping errors"
This reverts commit
f83331bab149e29fa2c49cf102c0cd8c3f1ce9f9.
As the tests PPC64 (powernv platform) show, IOMMU pages are leaking
when transferring big amount of small packets (<=64 bytes),
"ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.
