sysfs: Don't allow the creation of symlinks we can't remove
Recently my tagged sysfs support revealed a flaw in the device core
that a few rare drivers are running into such that we don't always put
network devices in a class subdirectory named net/.
Since we are not creating the class directory the network devices wind
up in a non-tagged directory, but the symlinks to the network devices
from /sys/class/net are in a tagged directory. All of which works
until we go to remove or rename the symlink. When we remove or rename
a symlink we look in the namespace of the target of the symlink.
Since the target of the symlink is in a non-tagged sysfs directory we
don't have a namespace to look in, and we fail to remove the symlink.
Detect this problem up front and simply don't create symlinks we won't
be able to remove later. This prevents symlink leakage and fails in
a much clearer and more understandable way.

When a configured device is reset, the control endpoint's ring is reused.
If control transfers to the device were issued before the device is reset,
the dequeue pointer will be somewhere in the middle of the ring. If the
device is then issued an address with the set address command, the xHCI
driver must provide a valid input context for control endpoint zero.
The original code would give the hardware the original input context,
which had a dequeue pointer set to the top of the ring. This would cause
the host to re-execute any control transfers until it reached the ring's
enqueue pointer. When issuing a set address command for a device that has
just been configured and then reset, use the control endpoint's enqueue
pointer as the hardware's dequeue pointer.
Assumption: All control transfers will be completed or cancelled before
the set address command is issued to the device. If there are any
outstanding control transfers, this code will not work.

Commit
6c12db90f19727c76990e7f4801c67a148b30111 also seems to have
introduced a bug that is triggered when the command ring is about to wrap.
The inc_enq() function will not have moved the enqueue pointer past the
link TRB. It is supposed to be moved past the link TRB in prepare_ring(),
which should be called before a TD is enqueued. However, the
queue_command() function never calls the prepare_ring() function because
prepare_ring() is only supposed to be used for endpoint rings. That means
the enqueue pointer will not be moved past the link TRB, and will get
overwritten.
The fix is to make queue_command() call prepare_ring() with a fake
endpoint status (set to running). Then the enqueue pointer will get moved
past the link TRB.

drm/i915: Use the correct scanout alignment for fbcon.
This fixes a potential modesetting error during boot with plymouth on
Broadwater and Crestline introduced with 9df47c. The framebuffer was
hard-coding an alignment of 64K, but the modesetting code required the
documented alignment of 128K. The result was that we would attempt to
unbind the pinned fbcon buffer, triggering an ERROR and ultimately
failing the mode change.

drm/i915: make sure eDP panel is turned on
When enabling the eDP port, we need to make sure the panel is turned on
after training the link. If we don't, it likely won't come back after
suspend or may not come up at all.
For unknown reasons, unlocking the panel regs before initiating a power
on sequence is necessary. There are known bugs in the PCH panel
sequencing logic, apparently this is one possible workaround.

drm/i915: Make G4X-style PLL search more permissive
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC

MIPS: MTX-1: Fix PCI on the MeshCube and related boards
This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1:
Use linux gpio api." (
bb706b28bbd647c2fd7f22d6bf03a18b9552be05) which broke
PCI bus operation. The problem is caused by alchemy_gpio2_enable() which
resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected
to GPIO2 and they obviously do not to like the reset. Since GPIO2 is
correctly initialized by the boot monitor (YAMON) it is not necessary to
call this function, so just remove it.
Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid
problems in case gpiolib gets initialized after PCI. And since alchemy
gpio_set_value() calls au_sync() we don't have to au_sync() again later.

When initrd is in use and a driver does request_module() in its
module_init (i.e. __initcall or device_initcall), a modprobe
process is created with VDSO mapping. But VDSO is inited even in
__initcall, i.e. on the same level (at the same time), so it may
not be inited yet (link order matters).

Driver-core: Always create class directories for classses that support namespaces.
This fixes the regression in 2.6.35-rcX where bluetooth network devices
would fail to be deleted from sysfs, causing their destruction and
recreation to fail. In addition this fixes the mac80211_hwsim driver
where it would leave around sysfs files when the driver was removed.
This problem is discussed at
https://bugzilla.kernel.org/show_bug.cgi?id=16257
The reason for the regression is that the network namespace support
added to sysfs expects and requires that network devices be put in
directories that can contain only network devices.
Today get_device_parent almost provides that guarantee for all class
devices, except for a specific exception when the parent of a class
devices is a class device. It would be nice to simply remove that
arguably incorrect special case, but apparently the input devices depend
on it being there. So I have only removed it for class devices with
network namespace support. Which today are the network devices.
It has been suggested that a better fix would be to change the parent
device from a class device to a bus device, which in the case of the
bluetooth driver would change /sys/class/bluetooth to /sys/bus/bluetoth,
I can not see how we would avoid significant userspace breakage if we
were to make that change.
Adding an extra directory in the path to the device will also be
userspace visible but it is much less likely to break things.
Everything is still accessible from /sys/class (for example), and it
fixes two bugs. Adding an extra directory fixes a 3 year old regression
introduced with the new sysfs layout that makes it impossible to rename
bnep0 network devices to names that conflict with hci device attributes
like hci_revsion. Adding an additional directory removes the new
failure modes introduced by the network namespace code.
If it weren't for the regession in the renaming of network devices I
would figure out how to just make the sysfs code deal with this
configuration of devices.
In summary this patch fixes regressions by changing:
"/sys/class/bluetooth/hci0/bnep0" to "/sys/class/bluetooth/hci0/net/bnep0".

For example, have this mapping:

P[W] | | LPA
\ PDE2 -> |---|
[R]
P have two children, PDE1 and PDE2, both PDE1 and PDE2 mapping the
same lage page(LPA). The P's access is WR, PDE1's access is WR,
PDE2's access is RO(just consider read-write permissions here)
When guest access PDE1, we will create a direct sp for LPA, the sp's
access is from P, is W, then we will mark the ptes is W in this sp.
Then, guest access PDE2, we will find LPA's shadow page, is the same as
PDE's, and mark the ptes is RO.
So, if guest access PDE1, the incorrect #PF is occured.

There's a couple of nasty bugs lurking in our huge page hashing code.
First, we don't check the access permission atomically with setting
the _PAGE_BUSY bit, which means that the PTE value we end up using
for the hashing might be different than the one we have checked
the access permissions for.
We've seen cases where that leads us to try to use an invalidated
PTE for hashing, causing all sort of "interesting" issues.
Then, we also failed to set _PAGE_DIRTY on a write access.
Finally, a minor tweak but we should return 0 when we find the
PTE busy, in order to just re-execute the access, rather than 1

ACPI: create "processor.bm_check_disable" boot param

This may be useful for a system running acpi_idle
where the BIOS exports FADT C-states, _CST IO C-states,
or _CST FFH C-states with the BM_STS bit set;
while configuring the chipset to set BM_STS
more frequently than perhaps is optimal.
Note that such systems may have been developed
using a tickful OS that would quickly clear BM_STS,
rather than a tickless OS that may go for some time
between checking and clearing BM_STS.
Note also that an alternative for newer systems
is to use the intel_idle driver, which always
ignores BM_STS, relying Linux device drivers
to register constraints explicitly via PM_QOS.
