ba124a4105 drm/nouveau/kms: reference vblank for crtc during pageflip.
Need to drm_vblank_get/put() the crtc involved in a
pending pageflip, or we might not get vblank irqs and
updates of vblank counts and timestamps for pageflip
events and flip completion.

The blob does not seem to write at that place for my NVAC, though it
does for my NV96, agreeing with what is done in the if/else structure
below. I guess someone forgot to remove the line when the if/else was

661f7fda21 slip: Fix deadlock in write_wakeup
Use schedule_work() to avoid potentially taking the spinlock in
interrupt context.

Commit cc9fa74e2a ("slip/slcan: added locking in wakeup function") added
necessary locking to the wakeup function and 367525c8c2/ddcde142be ("can:
slcan: Fix spinlock variant") converted it to spin_lock_bh() because the lock
is also taken in timers.

Disabling softirqs is not sufficient, however, as tty drivers may call
write_wakeup from interrupt context. This driver calls tty->ops->write() with
its spinlock held, which may immediately cause an interrupt on the same CPU and
subsequent spin_bug().

Simply converting to spin_lock_irq/irqsave() prevents this deadlock, but
causes lockdep to point out a possible circular locking dependency
between these locks:

(&(&sl->lock)->rlock){-.....}, at: slip_write_wakeup
(&port_lock_key){-.....}, at: serial8250_handle_irq.part.13

The slip transmit is holding the slip spinlock when calling the tty write.
This grabs the port lock. On an interrupt, the handler grabs the port
lock and calls write_wakeup which grabs the slip lock. This could be a
problem if a serial interrupt occurs on another CPU during the slip
transmit.

To deal with these issues, don't grab the lock in the wakeup function by
deferring the writeout to a workqueue. Also hold the lock during close
when de-assigning the tty pointer to safely disarm the worker and
timers.

This bug is easily reproducible on the first transmit when slip is
used with the standard 8250 serial driver.

f00e2b0ac3 vmxnet3: adjust ring sizes when interface is down
If ethtool is used to update ring sizes on a vmxnet3 interface that isn't
running, the change isn't stored, meaning the ring update is effectively is
ignored and lost without any indication to the user.

Other network drivers store the ring size update so that ring allocation uses
the new sizes next time the interface is brought up.  This patch modifies
vmxnet3 to behave this way as well

ebe06187bf epoll: fix use-after-free in eventpoll_release_file
This fixes use-after-free of epi->fllink.next inside list loop macro.
This loop actually releases elements in the body.  The list is
rcu-protected but here we cannot hold rcu_read_lock because we need to
lock mutex inside.

The obvious solution is to use list_for_each_entry_safe().  RCU-ness
isn't essential because nobody can change this list under us, it's final
fput for this file.

The bug was introduced by ae10b2b4eb ("epoll: optimize EPOLL_CTL_DEL

217886d3f3 cpufreq: cpufreq-cpu0: fix CPU_THERMAL dependency
5fbfbcd3e8 ("cpufreq: cpufreq-cpu0: remove dependency on THERMAL and
REGULATOR") was a little too quick in completely removing the dependency
on the THERMAL driver.

The problem is that while there are inline wrappers to turn the thermal
API calls into empty functions, those do not help if the cpu-thermal
driver is a loadable module and cpufreq-cpu0 is builtin.

Since CONFIG_CPU_THERMAL is a bool option that decides whether the cpu
code is built into the thermal module or not, we have to use a dependency
on the thermal driver itself. However, if CPU_THERMAL is disabled, we
don't need the dependency, hence the strange '!CPU_THERMAL || THERMAL'
construct.

12e27b1154 ACPI / ia64 / sba_iommu: Restore the working initialization ordering
Commit 66345d5f79 (ACPI / ia64 / sba_iommu: Use ACPI scan handler
for device discovery) changed the ordering of SBA (System Bus Adapter)
IOMMU initialization with respect to the PCI host bridge initialization
which broke things inadvertently, because the SBA IOMMU initialization
code has to run after the PCI host bridge has been initialized.

Fix that by reworking the SBA IOMMU ACPI scan handler so that it
claims the discovered matching ACPI device objects without attempting
to initialize anything and move the entire SBA IOMMU initialization
to sba_init() that runs after the PCI bus has been enumerated.

bca463e808 mwifiex: fix tx_info/rx_info overlap with PCIe dma_mapping
On PCIe Tx data path, network interface specific tx_info
parameters such as bss_num and bss_type are saved at
"skb->cb + sizeof(dma_addr_t)" (returned by MWIFIEX_SKB_TXCB).
Later mwifiex_map_pci_memory() called from
mwifiex_pcie_send_data() will memcpy
sizeof(struct mwifiex_dma_mapping) bytes to save PCIe DMA
address and length information at beginning of skb->cb.
This accidently overwrites bss_num and bss_type saved in skb->cb
previously because bss_num/bss_type and mwifiex_dma_mapping data
overlap.
Similarly, on PCIe Rx data path, rx_info parameters overlaps
with PCIe DMA address and length information too.

Fix it by defining mwifiex_cb structure and having
MWIFIEX_SKB_TXCB and MWIFIEX_SKB_RXCB return the correct address
of tx_info/rx_info using the structure members.

Also add a BUILD_BUG_ON to maks sure that mwifiex_cb structure
doesn't exceed the size of skb->cb.

1d80415db6 clocksource: exynos_mct: Don't reset the counter during boot and resume
Unfortunately on some exynos systems, resetting the mct counter also
resets the architected timer counter.  This can cause problems if the
architected timer driver has already been initialized because the kernel
will think that the counter has wrapped around, causing a big jump in
printk timestamps and delaying any scheduled clock events until the
counter reaches the value it had before it was reset.

The kernel code makes no assumptions about the initial value of the mct
counter so there is no reason from a software perspective to clear the
counter before starting it.  This also fixes the problems described in
the previous paragraph.

This patch is originally based on commit b3377d1865 ("ARM: 7064/1:
vexpress: Use wfi macro in platform_do_lowpower.")

Current Exynos CPU hotplug code includes a hardcoded WFI instruction,
in ARM encoding. When the kernel is compiled in Thumb-2 mode, this
is invalid and causes the machine to hang hard when a CPU is offlined.

Use wfi macro instead of the hardcoded WFI instruction.

As per the Final production Data Manual for OMAP5432,
SWPS050F(APRIL 2014)

There are only two OPPs - 1GHz and 1.5GHz. the older OPP_LOW has been
completely descoped. The Nominal voltages are still correct though.
However, expectation for final production configuration is operation
with Adaptive Body Bias (ABB) and Adaptive Voltage Scaling Class 0
operation.

There are no IDcode or version change information encoded to
programmatically detect this and software is supposed to NOT use
OPP_LOW(500MHz) anymore for all devices (legacy and production
samples).

945b2b2d25 netfilter: nf_nat: fix oops on netns removal
Quoting Samu Kallio:

 Basically what's happening is, during netns cleanup,
 nf_nat_net_exit gets called before ipv4_net_exit. As I understand
 it, nf_nat_net_exit is supposed to kill any conntrack entries which
 have NAT context (through nf_ct_iterate_cleanup), but for some
 reason this doesn't happen (perhaps something else is still holding
 refs to those entries?).

 When ipv4_net_exit is called, conntrack entries (including those
 with NAT context) are cleaned up, but the
 nat_bysource hashtable is long gone - freed in nf_nat_net_exit. The
 bug happens when attempting to free a conntrack entry whose NAT hash
 'prev' field points to a slot in the freed hash table (head for that
 bin).

We ignore conntracks with null nat bindings.  But this is wrong,
as these are in bysource hash table as well.

Restore nat-cleaning for the netns-is-being-removed case.
