many serial subdrivers are clearly written as if throttle/unthrottle
cannot sleep. This leads to unneeded atomic submissions. This
patch converts affected drivers in a way to makes very clear that
throttle/unthrottle can sleep. Thus future misdesigns can be avoided
and efficiency and reliability improved.
This removes any such assumption using GFP_KERNEL and spin_lock_irq()

The EHCI driver does some bounds checking when it's scheduling an iTD for
an active endpoint. It sets the local variable start to
stream->next_uframe and moves that variable further in the schedule if
necessary. However, the driver fails to do anything with start before
jumping to the ready label and setting the URB's starting frame to
stream->next_uframe. Alan Stern confirms the EHCI driver should set
stream->next_uframe to start before jumping.

This patch (as1294) fixes a problem that has plagued users for several
kernel releases. Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors. The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit. In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.
The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error. This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.
This fixes a large part of Bugzilla #14118.

When the host controller dies or is removed while a device is plugged in,
the USB core will attempt to deallocate the struct usb_device. That will
call into xhci_free_dev(). This function used to attempt to submit a
disable slot command to the host controller and clean up the device
structures when that command returned. Change xhci_free_dev() to skip the
command submission and just free the memory if the host controller died.

When the host controller dies (e.g. it is removed from a PCI card slot),
the xHCI driver cannot expect commands to complete. The buggy code this
patch fixes would mark an URB as canceled and then expect the URB to be
completed when the stop endpoint command completed. That would never
happen if the host controller was dead, so the USB core would just hang in
the disconnect code.
If the host controller died, and the driver asks to cancel an URB, free
any structures associated with that URB and immediately give it back.

- No need to check tty as it is checked again when processing.

1. The memory into which we copy 'u1@u2' needs space for u1, @,
u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument. So use a
temporary variable to pass to it, so we pass the original
value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
since we later kstrdup it.

Looking at the 2.6.31-rc9 code, it appears there is a race condition
in the event_buffer cleanup code path (shutdown). This could lead to
kernel panic as some CPUs may be operating on the event buffer AFTER
it has been freed. The attached patch solves the problem and makes
sure CPUs check if the buffer is not NULL before they access it as
some may have been spinning on the mutex while the buffer was being
freed.
The race may happen if the buffer is freed during pending reads. But
it is not clear why there are races in add_event_entry() since all
workqueues or handlers are canceled or flushed before the event buffer
is freed.

In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id
is destroyed") a call to the provider's reject handler was added to
destroy_cm_id() to fix a provider endpoint leak. This call needs to
be done with interrupts enabled. So unlock and relock around this
call. This is safe because:
1) the provider will do nothing with this endpoint until the iwcm either
accepts or rejects.
2) the lock is only released after the iwcm state is changed, so an
errant iwcm app that is destroying -and- rejecting the connection
concurrently will get a failure on one of the calls.

The address stored in the next link address is a word address but when
reading the OTP blocks, a byte address is used. Also if the blocks are
full and the last link pointer is not zero, then none of the blocks are
valid so return an error.
The algorithm is simply valid blocks have a next address and that
address's contents is zero.
Using the wrong address for the next link address gets arbitrary data,
obviously. In cases seen, the first block is considered valid when it is not.
If the block has in fact been invalidated there may be old data or
there may be no data, bad data, or partial data, there is no way of
telling. Without this patch it is possible that a device with valid OTP data
is unable to work.

A bug was seen on boards using a PLX 8518 switch device which advertises
AER on each of it's transparent bridges. The AER driver was loaded for
each bridge and this driver tried to access the AER source ID register
whenever an interrupt occured on the shared PCI INTX lines. The source
ID register does not exist on non root port PCIE device's which
advertise AER and trying to access this register causes a unsupported
request error on the bridge. Thus, when the next interrupt occurs,
another error is found and the non existent source ID register is
accessed again, and so it goes on.
The result is a spammed dmesg with unsupported request PCI express
errors on the bridge device that the AER driver is loaded against.

when there is no dedicated buffer memory.
Some hardware designs may not have dedicated buffer memory such as
on chip or off chip SRAM. In this case, only one memory resource is
supplied in the platform data instead of two. Then a DMA buffer can
be allocated from system memory and used for the transfer.

The packet buffer is allocated at 4 bytes boundary, but the IP header

While trying to work around spurious detection retries for
non-existent devices on slave links, commit
816ab89782 incorrectly added link
offline check logic before ata_eh_thaw() was called. This means that
if an occupied link goes down briefly at the time that offline check
was performed, device class will be cleared to ATA_DEV_NONE and libata
wouldn't retry thus failing detection of the device.
The offline check should be done after the port is thawed together
with online check so that such link glitches can be detected by the
interrupt handler and handled properly.

Commit a9327cac44 added seperate read

of read and write requests in progress seperately through sysfs.
But Corrado Zoccolo <czoccolo@gmail.com> reported getting strange
output from "iostat -kx 2". Global values for service time and
utilization were garbage. For interval values, utilization was always
100%, and service time is higher than normal.
So this was reverted by commit 0f78ab9899
The problem was in part_round_stats_single(), I missed the following:
if (now == part->stamp)
return;
- if (part->in_flight) {
+ if (part_in_flight(part)) {
__part_stat_add(cpu, part, time_in_queue,

After attempting to change the power state of a PCI device
pci_raw_set_power_state() doesn't check if the value it wrote into
the device's PCI_PM_CTRL register has been stored in there, but
unconditionally modifies the device's current_state field to reflect
the change. This may cause problems to happen if the power state of
the device hasn't been changed in fact, because it will make the PCI
PM core make a wrong assumption.
To prevent such situations from happening modify
pci_raw_set_power_state() so that it reads the device's PCI_PM_CTRL
register after writing into it and uses the value read from the
register to update the device's current_state field. Also make it
print a message saying that the device refused to change its power
state as requested (returning an error code in such cases would cause
suspend regressions to appear on some systems, where device drivers'
suspend routines return error codes if pci_set_power_state() fails).

fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

There is a race while re-reading the device characteristics. After
cleaning the memory area a cqr is build which reads the device
characteristics. This may take a rather long time and the device
characteristics structure is zero during this. Now it could be
possible that the block tasklet starts working and a new cqr will be
build. The build_cp command refers to the device characteristics
structure and this may lead into a divide by zero exception.
Fix this by re-reading the device characteristics into a temporary
structur and copy the data to the original structure. Also take the

There is a memory leak in /proc/cio_ignore. The iterator is allocated
in cio_ignore_proc_seq_start, but never freed in
cio_ignore_proc_seq_stop, because we cannot use the iterator
that was passed by seqfile. The seqfile interface passes the last
seen iterator to the stop function and not the first one. Since our
next function will return NULL at the end, the iter passed to
cio_ignore_proc_seq_stop is NULL. The original iter has leaked.
The solution is to use seq_open_private.

Curiously, Aspire 3810T issues many SATA feature enable commands via
_GTF, of which one is invalid and another is not supported by the
drive. In the process, it also enables FPDMA non-zero offset.
However, the feature also needs to be supported and enabled from the
controller and it's wrong to enable it from _GTF unless the controller
can do it by default.
Currently, this ends up enabling FPDMA non-zero offset only on the
drive side leading to NCQ command failures and eventual disabling of
NCQ. This patch makes libata filter out FPDMA non-zero offset enable
for the machine.

Update the AHCI driver to display all of the HBA capabilities defined in the

that undefined registers should always return 0 on read, but to be safe we
assume a value of 0 unless the controller reports AHCI version 1.2 or later.
The value can also be retrieved through sysfs as with the existing capability
field.
