471cff7c42 Char/Misc driver fix for 3.17-rc5
Here is one misc driver fix for 3.17-rc5.  It resolves a kernel oops
 that can happen in the lattice FPGA driver if the firmware isn't
 present on the system.
 
 It's been in the linux-next tree for a while now.

a6988b3343 Staging driver fixes for 3.17-rc5
Here are 3 tiny staging driver fixes for 3.17-rc5.  Two are fixes for
 the imx-drm driver, resolving issues that have been reported.  The other
 is a memory leak fix for the Android sync driver, due to changes that
 went into 3.17-rc1.
 
 All have been in linux-next for a while.

f39c010479 NFS: remove BUG possibility in nfs4_open_and_get_state
commit 4fa2c54b51
    NFS: nfs4_do_open should add negative results to the dcache.

used "d_drop(); d_add();" to ensure that a dentry was hashed
as a negative cached entry.
This is not safe if the dentry has an non-NULL ->d_inode.
It will trigger a BUG_ON in d_instantiate().
In that case, d_delete() is needed.

Also, only d_add if the dentry is currently unhashed, it seems
pointless removed and re-adding it unchanged.

6a73336bde PCI: Remove "no hotplug settings from platform" warning
We print way too many messages like this:

    pci 0000:00:00.0: no hotplug settings from platform
    pci 0000:00:00.0: using default PCI settings

This usually happens when the platform doesn't supply an ACPI _HPP method,
but the method is optional, so there's no point in warning about it.

Not only are the messages useless, but we call pci_configure_slot() far too
many times, so they're repeated many times.  I'll fix the overuse of
pci_configure_slot() too, but that will wait until the next merge window.

For now, just remove both log messages.

95389b08d9 KEYS: Fix termination condition in assoc array garbage collection
This fixes CVE-2014-3631.

It is possible for an associative array to end up with a shortcut node at the
root of the tree if there are more than fan-out leaves in the tree, but they
all crowd into the same slot in the lowest level (ie. they all have the same
first nibble of their index keys).

When assoc_array_gc() returns back up the tree after scanning some leaves, it
can fall off of the root and crash because it assumes that the back pointer
from a shortcut (after label ascend_old_tree) must point to a normal node -
which isn't true of a shortcut node at the root.

Should we find we're ascending rootwards over a shortcut, we should check to
see if the backpointer is zero - and if it is, we have completed the scan.

This particular bug cannot occur if the root node is not a shortcut - ie. if
you have fewer than 17 keys in a keyring or if you have at least two keys that
sit into separate slots (eg. a keyring and a non keyring).

This can be reproduced by:

	ring=`keyctl newring bar @s`
	for ((i=1; i<=18; i++)); do last_key=`keyctl newring foo$i $ring`; done
	keyctl timeout $last_key 2

Doing this:

	echo 3 >/proc/sys/kernel/keys/gc_delay

first will speed things up.

If we do fall off of the top of the tree, we get the following oops:

e4cf39ea47 video: ARM CLCD: Fix color model capabilities for DT platforms
The DT-based panel capabilities selection was picking up
a subset of available modes based on hardware configuration.
This was wrong, as the capabilities describe available
memory models and adapt the display controller to them
that the RGB output is wired up correctly (as in: R and
B components are not swapped).

This patch fixes it by removing the unnecessary limitation.

c012067961 Input: atkbd - do not try 'deactivate' keyboard on any LG laptops
We are getting more and more reports about LG laptops not having
functioning keyboard if we try to deactivate keyboard during probe.
Given that having keyboard deactivated is merely "nice to have"
instead of a hard requirement for probing, let's disable it on all
LG boxes instead of trying to hunt down particular models.

This change is prompted by patches trying to add "LG Electronics"/"ROCKY"
and "LG Electronics"/"LW60-F27B" to the DMI list.

96044694b8 xhci: fix oops when xhci resumes from hibernate with hw lpm capable devices
Resuming from hibernate (S4) will restart and re-initialize xHC.
The device contexts are freed and will be re-allocated later during device reset.

Usb core will disable link pm in device resume before device reset, which will
try to change the max exit latency, accessing the device contexts before they are re-allocated.

There is no need to zero (disable) the max exit latency when disabling hw lpm
for a freshly re-initialized xHC. So check that device context exists before
doing anything. The max exit latency will be set again after device reset when usb core
enables the link pm.

0eda06c7c1 usb: xhci: Fix OOPS in xhci error handling code
The xhci driver will OOPS on resume from S2/S3 if dma_alloc_coherent()
is out of memory. This is a result of two things:
1. xhci_mem_cleanup() in xhci-mem.c free's xhci->lpm_command if
it's not NULL, but doesn't set it to NULL after the free.
2. xhci_mem_cleanup() is called twice on resume, once for normal
restart and once from xhci_mem_init() if dma_alloc_coherent() fails,
resulting in a free of xhci->lpm_command that has already been freed.
The fix is to set xhci->lpm_command to NULL after freeing it.

c66f1c62e8 storage: Add single-LUN quirk for Jaz USB Adapter
The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware
seems to be identical to e.g. the Microtech XpressSCSI, using a Shuttle/
SCM chip set. However its firmware restricts it to only work with Jaz
drives.

On connecting the cable a message like this appears four times in the log:
 reset full speed USB device number 4 using uhci_hcd

That's non-fatal but the US_FL_SINGLE_LUN quirk fixes it.

d50582e06f xen/arm: remove mach_to_phys rbtree
Remove the rbtree used to keep track of machine to physical mappings:
the frontend can grant the same page multiple times, leading to errors
inserting or removing entries from the mach_to_phys tree.

Linux only needed to know the physical address corresponding to a given
machine address in swiotlb-xen. Now that swiotlb-xen can call the
xen_dma_* functions passing the machine address directly, we can remove
it.

340720be32 xen/arm: reimplement xen_dma_unmap_page & friends
xen_dma_unmap_page, xen_dma_sync_single_for_cpu and
xen_dma_sync_single_for_device are currently implemented by calling into
the corresponding generic ARM implementation of these functions. In
order to do this, firstly the dma_addr_t handle, that on Xen is a
machine address, needs to be translated into a physical address.  The
operation is expensive and inaccurate, given that a single machine
address can correspond to multiple physical addresses in one domain,
because the same page can be granted multiple times by the frontend.

To avoid this problem, we introduce a Xen specific implementation of
xen_dma_unmap_page, xen_dma_sync_single_for_cpu and
xen_dma_sync_single_for_device, that can operate on machine addresses
directly.

The new implementation relies on the fact that the hypervisor creates a
second p2m mapping of any grant pages at physical address == machine
address of the page for dom0. Therefore we can access memory at physical
address == dma_addr_r handle and perform the cache flushing there. Some
cache maintenance operations require a virtual address. Instead of using
ioremap_cache, that is not safe in interrupt context, we allocate a
per-cpu PAGE_KERNEL scratch page and we manually update the pte for it.

5ebc77de83 xen/arm: introduce XENFEAT_grant_map_identity
The flag tells us that the hypervisor maps a grant page to guest
physical address == machine address of the page in addition to the
normal grant mapping address. It is needed to properly issue cache
maintenance operation at the completion of a DMA operation involving a
foreign grant.

eb35bdd7bc arm64: flush TLS registers during exec
Nathan reports that we leak TLS information from the parent context
during an exec, as we don't clear the TLS registers when flushing the
thread state.

This patch updates the flushing code so that we:

  (1) Unconditionally zero the tpidr_el0 register (since this is fully
      context switched for native tasks and zeroed for compat tasks)

  (2) Zero the tp_value state in thread_info before clearing the
      tpidrr0_el0 register for compat tasks (since this is only writable
      by the set_tls compat syscall and therefore not fully switched).

A missing compiler barrier is also added to the compat set_tls syscall.

3856e54837 virtio-rng: fix stuck of hot-unplugging busy device
When we try to hot-remove a busy virtio-rng device from QEMU monitor,
the device can't be hot-removed. Because virtio-rng driver hangs at
wait_for_completion_killable().

This patch exits the waiting by completing have_data completion before
unregistering, resets data_avail to avoid the hwrng core use wrong
buffer bytes.

7a9744cb45 ALSA: hda - Fix invalid pin powermap without jack detection
When a driver is set up without the jack detection explicitly (either
by passing a model option or via a specific fixup), the pin powermap
of IDT/STAC codecs is set up wrongly, resulting in the silence
output.  It's because of a logic failure in stac_init_power_map().
It tries to avoid creating a callback for the pins that have other
auto-hp and auto-mic callbacks, but the check is done in a wrong way
at a wrong time.  The stac_init_power_map() should be called after
creating other jack detection ctls, and the jack callback should be
created only for jack-detectable widgets.

This patch fixes the check in stac_init_power_map() and its callee
at the right place, after snd_hda_gen_build_controls().
