069915b946 Five bug-fixes:
- When booting as PVHVM we would try to use PV console - but would not validate
    the parameters causing us to crash during restore b/c we re-use the wrong event
    channel.
  - When booting on machines with SR-IOV PCI bridge we didn't check for the bridge
    and tried to use it.
  - Under AMD machines would advertise the APERFMPERF resulting in needless amount
    of MSRs from the guest.
  - A global value (xen_released_pages) was not subtracted at bootup when pages
    were added back in. This resulted in the balloon worker having the wrong
    account of how many pages were truly released.
  - Fix dead-lock when xen-blkfront is run in the same domain as xen-blkback.

41c8c53523 USB fixes for 3.5-rc3
Here are a bunch of tiny fixes for the USB core and drivers for 3.5-rc3
 
 A bunch of gadget fixes, and new device ids, as well as some fixes for a number
 of different regressions that have been reported recently.  We also fixed some
 PCI host controllers to resolve a long-standing bug with a whole class of host
 controllers that have been plaguing people for a number of kernel releases,
 preventing their systems from suspending properly.

b3a3dd074f USB: fix gathering of interface associations
TEAC's UD-H01 (and probably other devices) have a gap in the interface
number allocation of their descriptors:

  Configuration Descriptor:
    bLength                 9
    bDescriptorType         2
    wTotalLength          220
    bNumInterfaces          3
    [...]
    Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber        0
      bAlternateSetting       0
      [...]
    Interface Association:
      bLength                 8
      bDescriptorType        11
      bFirstInterface         2
      bInterfaceCount         2
      bFunctionClass          1 Audio
      bFunctionSubClass       0
      bFunctionProtocol      32
      iFunction               4
    Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber        2
      bAlternateSetting       0
      [...]

Once a configuration is selected, usb_set_configuration() walks the
known interfaces of a given configuration and calls find_iad() on
each of them to set the interface association pointer the interface
is included in.

The problem here is that the loop variable is taken for the interface
number in the comparison logic that gathers the association. Which is
fine as long as the descriptors are sane.

In the case above, however, the logic gets out of sync and the
interface association fields of all interfaces beyond the interface
number gap are wrong.

Fix this by passing the interface's bInterfaceNumber to find_iad()
instead.

Shimoda, Yoshihiro
5897b03829 usb: ehci-sh: fix illegal phy_init() running when platform_data is NULL
If the platform_data is not set, pdata will be uninitialized value.
Since the driver has the following code, if the condition is true when
the pdata is uninitialized value, the driver may jump to the illegal
phy_init().

	if (pdata && pdata->phy_init)
		pdata->phy_init();

This patch also fixes the following warning:

  CC      drivers/usb/host/ehci-hcd.o

354ab8567a Fix OMAP EHCI suspend/resume failure (i693)
Its observed with some PHY, the 60Mhz clock gets
cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state.

So on starting port suspend, make sure the 60Mhz clock to EHCI
is kept alive using an internal clock, so that EHCi can cleanly
transition its hw state machine on a port suspend.

Its not proven if this is the issue hit on USB3333,
but the symptoms look very similar.

After commit aaa0ef289a "PS3 EHCI QH
read work-around", Terratec Grabby (em28xx) stopped working with AMD
Geode LX 800 (USB controller AMD CS5536). Since this is a PS3 only
fix, the following patch adds a conditional block around it.

57e04bdb3e xhci: Bug fixes for 3.5
Hi Greg,
 
 Here's five bug fixes for 3.5.  They fix some memory leaks in the
 bandwidth calculation code, fix a couple bugs in the USB3 Link PM
 patchset, and make system suspend and resume work on platforms with the
 AsMedia ASM1042 xHCI host controller.

xhci: Bug fixes for 3.5

Hi Greg,

Here's five bug fixes for 3.5.  They fix some memory leaks in the
bandwidth calculation code, fix a couple bugs in the USB3 Link PM
patchset, and make system suspend and resume work on platforms with the
AsMedia ASM1042 xHCI host controller.

622eb783fe xHCI: Increase the timeout for controller save/restore state operation
When system software decides to power down the xHC with the intent of
resuming operation at a later time, it will ask xHC to save the internal
state and restore it when resume to correctly recover from a power event.
Two bits are used to enable this operation: Save State and Restore State.

xHCI spec 4.23.2 says software should "Set the Controller Save/Restore
State flag in the USBCMD register and wait for the Save/Restore State
Status flag in the USBSTS register to transition to '0'". However, it does
not define how long software should wait for the SSS/RSS bit to transition
to 0.

Currently the timeout is set to 1ms. There is bug report
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697)
indicates that the timeout is too short for ASMedia ASM1042 host controller
to save/restore the state successfully. Increase the timeout to 10ms helps to
resolve the issue.

This patch should be backported to stable kernels as old as 2.6.37, that
contain the commit 5535b1d5f8 "USB: xHCI:
PCI power management implementation"

32f1d2c536 xhci: Don't free endpoints in xhci_mem_cleanup()
This patch fixes a few issues introduced in the recent fix
[f8a9e72d: USB: fix resource leak in xhci power loss path]

- The endpoints listed in bw table are just links and each entry is an
 array member of dev->eps[].  But the commit above adds a kfree() call
 to these instances, and thus it results in memory corruption.

- It clears only the first entry of rh_bw[], but there can be multiple
  ports.

- It'd be safer to clear the list_head of ep as well, not only
  removing from the list, as it's checked in
  xhci_discover_or_reset_device().

This patch should be backported to kernels as old as 3.2, that contain
the commit 839c817ce6 "xhci: Store

46ed8f00d8 xhci: Fix invalid loop check in xhci_free_tt_info()
xhci_free_tt_info() may access the invalid memory when it removes the
last entry but the list is not empty.  Then tt_next reaches to the
list head but it still tries to check the tt_info of that entry.

This patch fixes the bug and cleans up the messy code by rewriting
with a simple list_for_each_entry_safe().

afff07e61a usb-storage: Add 090c:1000 to unusal-devs
This device gives a bogus answer to get_capacity(16):

So set the quirk flag to avoid using get_capacity(16) with it:

d6cb3e4138 bnx2x: fix checksum validation
bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on
encapsulated segments. TCP stack happily accepts frames with bad
checksums, if they are inside a GRE or IPIP encapsulation.

Our understanding is that if no IP or L4 csum validation was done by the
hardware, we should leave ip_summed as is (CHECKSUM_NONE), since
hardware doesn't provide CHECKSUM_COMPLETE support in its cqe.

Then, if IP/L4 checksumming was done by the hardware, set
CHECKSUM_UNNECESSARY if no error was flagged.

Patch based on findings and analysis from Robert Evans

0b84704a2d USB: serial-generic: use a single set of device IDs
The usb-serial-generic driver uses different device IDs for its USB
matching and its serial matching.  This can lead to problems: The
driver can end up getting bound to a USB interface without being
allowed to bind to the corresponding serial port.

This patch (as1557) fixes the problem by using the same device ID
table (the one that can be altered by the "vendor=" and "product="
module parameters) for both purposes.  The unused table is removed.
Now the driver will bind only to the intended devices.

954c3f8a5f USB: serial: Enforce USB driver and USB serial driver match
We need to make sure that the USB serial driver we find
matches the USB driver whose probe we are currently
executing. Otherwise we will end up with USB serial
devices bound to the correct serial driver but wrong
USB driver.

An example of such cross-probing, where the usbserial_generic
USB driver has found the sierra serial driver:

So we end up with a mismatch between the USB driver and the
USB serial driver.  The reason for the above is simple: The
USB driver probe will succeed if *any* registered serial
driver matches, and will use that serial driver for all
serial driver functions.

This makes ref counting go wrong. We count the USB driver
as used, but not the USB serial driver.  This may result
in Oops'es as demonstrated by Johan Hovold <jhovold@gmail.com>:

Fix by only evaluating serial drivers pointing back to the
USB driver we are currently probing.  This still allows two
or more drivers to match the same device, running their
serial driver probes to sort out which one to use.

c2fb8a3fa2 USB: add NO_D3_DURING_SLEEP flag and revert 151b612847
This patch (as1558) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers.  Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.

After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state.  Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.

The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep.  Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.

A similar patch has already been applied as commit
151b612847 (USB: EHCI: fix crash during
suspend on ASUS computers).  The patch supersedes that one and reverts
it.  There are two differences:

	The old patch added the flag at the USB level; this patch
	adds it at the PCI level.

	The old patch applied to all chipsets with the same vendor,
	subsystem vendor, and product IDs; this patch makes an
	exception for a known-good system (based on DMI information).

092e1dc3f2 qla2xxx: Don't crash if we can't find cmd for failed CTIO
In qlt_do_ctio_completion(), there's no point in calling
qlt_term_ctio_exchange() with a NULL cmd -- all that it does is crash
in a NULL pointer dereference, since it does

	qlt_send_term_exchange(vha, cmd, &cmd->atio, 1);

and dereferencing &cmd->atio is a bad idea if cmd itself is NULL.

If we really need to do this, we could take the values from the
failed CTIO we're processing, but it's not clear if it's worth
the replumbing to do that.

3578ddba1a tcm_qla2xxx: Don't insert nacls without sessions into the btree
When we create an explicit node ACL in tcm_qla2xxx_make_nodeacl(),
there is a call to tcm_qla2xxx_setup_nacl_from_rport(), which puts the
node ACL into the lport_fcport_map even though there is no session yet
for the initiator.  Since the only time we remove entries from this
map is when we free a session, this means that if we later delete this
node ACL without the initiator ever creating a session, we'll leave
the nacl pointer in the btree pointing at freed memory.

This is especially bad if that initiator later does send us a command
that would cause us to create a dynamic ACL and session: we'll find
the stale freed nacl pointer in the btree and end up with use-after-free.

We could add more code to clear the btree entry when deleting the
explicit nacl, but the original insertion is pointless: without a
session attached, we'll just have to update the entry when a session
appears anyway.  So we can just delete tcm_qla2xxx_setup_nacl_from_rport()
and the code that calls it.

59e4f541ba target: Return error to initiator if SET TARGET PORT GROUPS emulation fails
The error paths in target_emulate_set_target_port_groups() are all
essentially "rc = -EINVAL; goto out;" but the code at "out:" ignores
rc and always returns success.  This means that even if eg explicit
ALUA is turned off, the initiator will always see a good SCSI status
for SET TARGET PORT GROUPS.

Fix this by returning rc as is intended.  It appears this bug was
added by the following patch:

f2d5d9b90b tcm_qla2xxx: Clear session s_id + loop_id earlier during shutdown
This patch adds a new tcm_qla2xxx_clear_sess_lookup() call to clear session
specific s_id + loop_id entries used for se_node_acl pointer lookup ahead
of releasing se_session within the process context workqueue callback in
tcm_qla2xxx_free_session().

It makes the call in existing tcm_qla2xxx_clear_nacl_from_fcport_map()
code invoked from qlt_unreg_sess() in interrupt context w/ hardware_lock
held, ahead of the process context callback into qlt_free_session_done()
-> tcm_qla2xxx_free_session().

We are doing this to address a race between incoming ATIO or TMR packets
using stale se_node_acl pointer once session shutdown has been invoked via
qlt_unreg_sess() in qla_target.c LLD code, and when the entire tcm_qla2xxx
endpoint has not been forced into shutdown w/ echo 0 > ../$QLA2XXX_PORT/enable
