commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream.
The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.
Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.

commit a2098250fbda149cfad9e626afe80abe3b21e574 upstream.
In order to have any realistic chance of calculating proper
ACR values, we need to be able to calculate both N and CTS,
not just CTS. We still aim for the ideal N as specified in
the HDMI spec though.

commit 05104a4e8713b27291c7bb49c1e7e68b4e243571 upstream.
The warning for the irq remapping broken check in intel_irq_remapping.c is
pretty pointless. We need the warning, but we know where its comming from, the
stack trace will always be the same, and it needlessly triggers things like
Abrt. This changes the warning to just print a text warning about BIOS being
broken, without the stack trace, then sets the appropriate taint bit. Since we
automatically disable irq remapping, theres no need to contiue making Abrt jump
at this problem

commit f9423606ade08653dd8a43334f0a7fb45504c5cc upstream.
The BUG_ON in drivers/iommu/intel-iommu.c:785 can be triggered from userspace via
VFIO by calling the VFIO_IOMMU_MAP_DMA ioctl on a vfio device with any address
beyond the addressing capabilities of the IOMMU. The problem is that the ioctl code
calls iommu_iova_to_phys before it calls iommu_map. iommu_map handles the case that
it gets addresses beyond the addressing capabilities of its IOMMU.
intel_iommu_iova_to_phys does not.
This patch fixes iommu_iova_to_phys to return NULL for addresses beyond what the
IOMMU can handle. This in turn causes the ioctl call to fail in iommu_map and
(correctly) return EFAULT to the user with a helpful warning message in the kernel
log.

commit c8760069627ad3b0dbbea170f0c4c58b16e18d3d upstream.
Current MMC driver doesn't handle generic error (bit19 of device
status) in write sequence. As a result, write data gets lost when
generic error occurs. For example, a generic error when updating a
filesystem management information causes a loss of write data and
corrupts the filesystem. In the worst case, the system will never
boot.
This patch includes the following functionality:
1. To enable error checking for the response of CMD12 and CMD13
in write command sequence
2. To retry write sequence when a generic error occurs
Messages are added for v2 to show what occurs.

[ Upstream commit f5e0d34382e18f396d7673a84df8e3342bea7eb6 ]
When user linkup is enabled and user sets linkup of individual port,
we need to recompute linkup (carrier) of master interface so the change
is reflected. Fix this by calling __team_carrier_check() which does the
needed work.
Please apply to all stable kernels as well. Thanks.

When a skb has frags, bytes_compl plus skb->len nr_frags times in cp_tx().
It's not the correct value(actually, it should plus skb->len once) and it
will trigger the BUG_ON(bytes_compl > num_queued - dql->num_completed).
So only increase bytes_compl when finish sending all frags. pkts_compl also
has a wrong value, fix it too.
It's introduced by commit 871f0d4c ("8139cp: enable bql").

[ Upstream commit 1bac1072425c86f1ac85bd5967910706677ef8b3 ]
Windows driver will enable ALDPS function, but linux driver and firmware
do not have any configuration related to ALDPS function for 8168g.
So restart system to linux and remove the NIC cable, LAN enter ALDPS,
then LAN RX will be disabled.
This issue can be easily reproduced on dual boot windows and linux
system with RTL_GIGA_MAC_VER_40 chip.
Realtek said, ALDPS function can be disabled by configuring to PHY,
switch to page 0x0A43, reg0x10 bit2=0.

[ Upstream commit f3d3342602f8bcbf37d7c46641cb9bca7618eb1c ]
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

[ Upstream commit 1ca1a4cf59ea343a1a70084fe7cc96f37f3cf5b1 ]
In af3e095a1fb4, Erik Jacobsen fixed one type of unaligned access
bug for ia64 by converting a 64-bit write to use put_unaligned().
Unfortunately, since gcc will convert a short memset() to a series
of appropriately-aligned stores, the problem is now visible again
on tilegx, where the memset that zeros out proc_event is converted
to three 64-bit stores, causing an unaligned access panic.
A better fix for the original problem is to ensure that proc_event
is aligned to 8 bytes here. We can do that relatively easily by
arranging to start the struct cn_msg aligned to 8 bytes and then
offset by 4 bytes. Doing so means that the immediately following
proc_event structure is then correctly aligned to 8 bytes.
The result is that the memset() stores are now aligned, and as an
added benefit, we can remove the put_unaligned() calls in the code.

With the introduction of "xen-netback: Don't destroy the netdev until
the vif is shut down" (upstream commit id 279f438e36), vif disconnect
and free are separated. However in the backported version reference
counting code was not correctly modified, and the reset of vif->irq
was lost. If frontend goes through vif life cycle more than once the
reference counting is skewed.
This patch adds back the missing vif->irq reset line. It also moves
several lines of the reference counting code to vif_free, so the moved
code corresponds to the counterpart in vif_alloc, thus the reference
counting is balanced.

commit c1de4a9557d9e25e41fc4ba034b9659152205539 upstream.
4965 version of Eric patch "iwl3945: better skb management in rx path".
It fixes several problems :
1) skb->truesize is underestimated.
We really consume PAGE_SIZE bytes for a fragment,
not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

commit 45fe142cefa864b685615bcb930159f6749c3667 upstream.
Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()
It turns out iwl3945 has several problems :
1) skb->truesize is underestimated.
We really consume PAGE_SIZE bytes for a fragment,
not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

commit 9736a89dafe07359d9c86bf9c3b815a250b354bc upstream.
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:

Instead, let's enforce a limit for the buffer.
In the specific case of this frontend, only ttpci uses it. The maximum
number of messages there is two, on I2C read operations. As the logic
can add an extra operation, change the size to 3.

Instead, let's enforce a limit for the buffer.
In the specific case of this driver, the maximum limit is 80, used only
on tm6000 driver. This limit is due to the size of the USB control URBs.
Ok, it would be theoretically possible to use a bigger size on PCI
devices, but the firmware load time is already good enough. Anyway,
if some usage requires more, it is just a matter of also increasing
the buffer size at load_firmware().

commit 65e2f1cb3fe0f0630834b9517ba8f631936f325c upstream.
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
drivers/media/usb/dvb-usb-v2/af9015.c:433:1: warning: 'af9015_eeprom_hash' uses dynamic stack allocation [enabled by default]
In this specific case, it is a gcc bug, as the size is a const, but
it is easy to just change it from const to a #define, getting rid of
the gcc warning.
