User applications frequently hit problems when they try to use
the kernel headers directly, rather than the exported headers.This adds an explicit warning for this case, and points to
a URL holding an explanation of why this is wrong and what
to do about it.Signed-off-by: Arnd Bergmann

The Makefile.lib will call "echo -ne" to append uncompressed kernel size to
bzip2/lzma kernel image.
The "echo" here depends on the shell that /bin/sh pointing to.
On Ubuntu system, the /bin/sh is pointing to dash, which does not support
"echo -e" at all. Use /bin/echo instead of shell echo should always be safe.Signed-off-by: Alek Du

The binrpm-pkg target (binary RPM only) fails when called with
KBUILD_OUTPUT set. This patch makes it work.For the rpm-pkg target (source + binary RPM), building with
KBUILD_OUTPUT set is not possible and also not needed as the
actual build is done in a temporary directory anyway, so check
that KBUILD_OUTPUT is not set in that case to avoid later errors.Signed-off-by: Frans Pop

An interestingly corrupted romfs file system exposed a problem with the
romfs_dev_strnlen function: it's passing the wrong value to its helpers.
Rather than limit the string to the length passed in by the callers, it

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.Signed-off-by: Sarah Sharp

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.Signed-off-by: Sarah Sharp
Signed-off-by: Greg Kroah-Hartman -
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.Signed-off-by: Sarah Sharp

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.The patch adds a new flag to keep track of whether or not attach has
been called.Signed-off-by: Alan Stern
