When running heavy traffic we stop the tx queue if the pending

On a freescale imx6q platform, a hardware phy chip KSZ9021 is
recognized as a KS8001 chip by the current driver like this:
eth0: Freescale FEC PHY driver [Micrel KS8001 or KS8721]
KSZ9021 has phy_id 0x00221610, while KSZ8001 has phy_id
0x0022161a, the current phy_id_mask (0x00fffff0/0x00ffff10) can't
distinguish them. So change phy_id_mask to resolve this problem.
Although the micrel datasheet says that the 4 LSB of phyid2 register
contains the chip revision number and the current driver is designed
to follow this rule, in reality the chip implementation doesn't follow
it.

This patch fixes a potential hole when configuring the cycle counter used to
generate the nanosecond time clock. This clock is based off of the SYSTIME
registers along with the TIMINCA registers. The TIMINCA register determines
the increment to be added to the SYSTIME registers every DMA clock tick. This
register needs to be reconfigured whenever the link-speed changes. However,
the value calculated stays the same when link is down and when link is up.
Misconfiguration can occur if the link status changes due to a reset, which
causes the TIMINCA register to be reset. This reset puts the device in an
unstable state where the SYSTIME registers stop incrementing and the PTP
protocol does not function.
The solution is to double check the TIMINCA value and always reset the value
if the register is zero. This prevents a misconfiguration bug that halts the
PHC.

This reverts commit 092945e11c.
This commit prevents a DP screen from properly training the link.
Oddly enough it works, once the machine has been warm-booted with an
older kernel.
According to DP docs this _should_ have been the right precharge time.
Also, the commit that originally introduces this was just general snb
DP enabling and didn't mention any specific reason for this special
value. Whatever, trust the reporter that this makes things worse and
let's just revert it.
v2: Less spelling fail.

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.

When booting with Device Tree enabled, platform specific information
is gathered by parsing the DT binary. Platform data is subsequently
populated with the result. The memory required for this is not
automatically allocated during Device Tree boot, so we'll do it here
instead.

pl330_update() stores a pointer to the thrd->req that finished, which
contains a pointer to the corresponding pl330_req. This is done with
the pl330_lock held. Then, it iterates through the req_done list,
calling the callback for each of the requests that are done. The
problem is that the driver releases the lock before calling the
callback for each of the callbacks. pl330_submit_req() running in
another processor can then acquire the lock and insert another request
in one of the thrd->req that hasn't been processed yet, replacing the
pointer to pl330_req there. When the callback returns in
pl330_update() and the next rqdone is popped from the list, it
dereferences the pl330_req pointer to the just scheduled pl330_req,
instead of the one that has finished, calling pl330 with the wrong r.
This patch fixes this by storing the pointer to pl330_req directly in
the list.

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.

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.
Sarah Sharp
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"

This patch fixes a few issues introduced in the recent fix

- 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().

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().

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.

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.

We need to make sure that the USB serial driver we find

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.

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).

ensure that the PLL-WAR for AR9485/AR9340 is executed only if the STA is
associated (or) IBSS/AP mode had started beaconing. Ideally this WAR
is needed to recover from some rare beacon stuck during stress testing.
Before the STA is associated/IBSS had started beaconing, PLL4(0x1618c)
always seem to have zero even though we had configured PLL3(0x16188) to
query about PLL's locking status. When we keep on polling infinitely PLL4's
8th bit(ie check for PLL locking measurements is done), machine hangs
due to softlockup.

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.

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.

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:

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

This patch converts tcm_qla2xxx code to use an internal kref_put() for
se_session->sess_kref in order to ensure that qla_hw_data->hardware_lock
can be held while calling qlt_unreg_sess() for the final put.

This patch adds an optional target_core_fabric_ops->put_session() caller
within the existing target_put_session() code path.
This is required by tcm_qla2xxx code in order to invoke it's own fabric
specific session shutdown handler using se_session->sess_kref.

The driver supports a maximum number of ports configurable at compile
time. Make sure the probe() method fails when registering a port that
exceeds the maximum instead of returning success without registering the
port.
This fixes a crash at system suspend time, when the driver tried to
suspend a non-registered port using the UART core.

When probing fails, the driver must not try to cleanup resources that
have not been initialized. Fix this.

The __devinitconst section can't be referenced
from usb_serial_device structure. Thus removed it as
it done in other mos* device drivers.
Error itself:

The low level helper returns 1 on success. The ioctl should however return
0. As this is the only user of the helper return, make the helper return 0 or
an error code.

Later firmwares for this device now have proper subclass and
protocol info so we can identify it nicely without needing to use
the blacklist. I'm not removing the old 0xff matching as there
may be devices in the field that still need that.

IO_DATA_PATH_WIDTH_8 is 0, so a bit-and with it is always false. The
value IO_DATA_PATH_WIDTH covers the bits of the IO_DATA_PATH constants, so
first pick those bits and then make the test using !=.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
