usb: wusbcore: clean up urb dequeue process
This patch updates URB dequeue handling in wusbcore to make it more
reliable when a URB has been broken up into multiple WUSB transfer
request segments.
In wa_urb_dequeue, don't mark segments in the WA_SEG_SUBMITTED,
WA_SEG_PENDING or WA_SEG_DTI_PENDING states as completed if an ABORT
TRANSFER request was sent to the HWA to clean them up. Wait for the
HWA to return a transfer result indicating that it has aborted the
request before cleaning it up. This prevents the DTI state machine
from losing track of transfers and avoids confusion in the case where a
read transfer segment is dequeued after the driver has received the
transfer result but before the data is received.

While this code is fixable, the commit itself fails on several levels:
- it should have been a separate helper function

- it casts a const char * over into char *
- sloppy style

PCI: Workaround missing pci_set_master in pci drivers
Ben Herrenschmidt found that commit
928bea964827 ("PCI: Delay enabling
bridges until they're needed") breaks PCI in some powerpc environments.
The reason is that the PCIe port driver will call pci_enable_device() on
the bridge, so the device is enabled, but skips pci_set_master because
pcie_port_auto and no acpi on powerpc.
Because of that, pci_enable_bridge() later on (called as a result of the
child device driver doing pci_enable_device) will see the bridge as
already enabled and will not call pci_set_master() on it.
Fixed by add checking in pci_enable_bridge, and call pci_set_master
if driver skip that.
That will make the code more robot and wade off problem for missing
pci_set_master in drivers.

x86/microcode/AMD: Fix patch level reporting for family 15h
On AMD family 14h, applying microcode patch on the a core (core0)

USB: Fix breakage in ffs_fs_mount()
There's a bunch of failure exits in ffs_fs_mount() with
seriously broken recovery logics. Most of that appears to stem
from misunderstanding of the ->kill_sb() semantics; unlike
->put_super() it is called for *all* superblocks of given type,
no matter how (in)complete the setup had been. ->put_super()
is called only if ->s_root is not NULL; any failure prior to
setting ->s_root will have the call of ->put_super() skipped.
->kill_sb(), OTOH, awaits every superblock that has come from
sget().
Current behaviour of ffs_fs_mount():
We have struct ffs_sb_fill_data data on stack there. We do
ffs_dev = functionfs_acquire_dev_callback(dev_name);
and store that in data.private_data. Then we call mount_nodev(),
passing it ffs_sb_fill() as a callback. That will either fail
outright, or manage to call ffs_sb_fill(). There we allocate an
instance of struct ffs_data, slap the value of ffs_dev (picked
from data.private_data) into ffs->private_data and overwrite
data.private_data by storing ffs into an overlapping member
(data.ffs_data). Then we store ffs into sb->s_fs_info and attempt
to set the rest of the things up (root inode, root dentry, then
create /ep0 there). Any of those might fail. Should that
happen, we get ffs_fs_kill_sb() called before mount_nodev()
returns. If mount_nodev() fails for any reason whatsoever,
we proceed to
functionfs_release_dev_callback(data.ffs_data);
That's broken in a lot of ways. Suppose the thing has failed in
allocation of e.g. root inode or dentry. We have
functionfs_release_dev_callback(ffs);
ffs_data_put(ffs);
done by ffs_fs_kill_sb() (ffs accessed via sb->s_fs_info), followed by
functionfs_release_dev_callback(ffs);
from ffs_fs_mount() (via data.ffs_data). Note that the second
functionfs_release_dev_callback() has every chance to be done to freed memory.
Suppose we fail *before* root inode allocation. What happens then?
ffs_fs_kill_sb() doesn't do anything to ffs (it's either not called at all,
or it doesn't have a pointer to ffs stored in sb->s_fs_info). And
functionfs_release_dev_callback(data.ffs_data);
is called by ffs_fs_mount(), but here we are in nasal daemon country - we
are reading from a member of union we'd never stored into. In practice,
we'll get what we used to store into the overlapping field, i.e. ffs_dev.
And then we get screwed, since we treat it (struct gfs_ffs_obj * in
disguise, returned by functionfs_acquire_dev_callback()) as struct
ffs_data *, pick what would've been ffs_data ->private_data from it
(*well* past the actual end of the struct gfs_ffs_obj - struct ffs_data
is much bigger) and poke in whatever it points to.
FWIW, there's a minor leak on top of all that in case if ffs_sb_fill()
fails on kstrdup() - ffs is obviously forgotten.
The thing is, there is no point in playing all those games with union.
Just allocate and initialize ffs_data *before* calling mount_nodev() and
pass a pointer to it via data.ffs_data. And once it's stored in
sb->s_fs_info, clear data.ffs_data, so that ffs_fs_mount() knows that
it doesn't need to kill the sucker manually - from that point on
we'll have it done by ->kill_sb().

driver core : Fix use after free of dev->parent in device_shutdown
The put_device(dev) at the bottom of the loop of device_shutdown
may result in the dev being cleaned up. In device_create_release,
the dev is kfreed.
However, device_shutdown attempts to use the dev pointer again after
put_device by referring to dev->parent.
Copy the parent pointer instead to avoid this condition.
This bug was found on Chromium OS's chromeos-3.8, which is based on v3.8.11.
See bug report : https://code.google.com/p/chromium/issues/detail?id=297842
This can easily be reproduced when shutting down with
hidraw devices that report battery condition.
Two examples are the HP Bluetooth Mouse X4000b and the Apple Magic Mouse.
For example, with the magic mouse :
The dev in question is "hidraw0"
dev->parent is "magicmouse"
In the course of the shutdown for this device, the input event cleanup calls
a put on hidraw0, decrementing its reference count.
When we finally get to put_device(dev) in device_shutdown, kobject_cleanup
is called and device_create_release does kfree(dev).
dev->parent is no longer valid, and we may crash in
put_device(dev->parent).
This change should be applied on any kernel with this change :

sysfs: Restrict mounting sysfs
Don't allow mounting sysfs unless the caller has CAP_SYS_ADMIN rights
over the net namespace. The principle here is if you create or have
capabilities over it you can mount it, otherwise you get to live with
what other people have mounted.
Instead of testing this with a straight forward ns_capable call,
perform this check the long and torturous way with kobject helpers,
this keeps direct knowledge of namespaces out of sysfs, and preserves
the existing sysfs abstractions.

USB: EHCI: make ehci-w90X900 a separate driver
Separate the W90X900(W90P910) on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before W90X900(W90P910)
can be booted with a multi-platform kernel
and an ehci driver that only works on one of them.
With the infrastructure added by Alan Stern in patch
3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the w90X900 bus glue.
This patch is rebased on greghk/usb-next 3.12 rc1.

USB: serial: invoke dcd_change ldisc's handler.
The DCD pin of the serial port can receive a PPS signal. By calling
the port line discipline dcd handle, this patch allow to monitor PPS
through USB serial devices.
However the performance aren't as good as the uart drivers, so
document this point too.
