The core of the driver expects the resource array from the glue layer
to be indexed by even numbers, as is the case for 64-bit PCI resources.
This doesn't hold true for others, ACPI in this instance, which leads
to an out-of-bounds access and an ioremap() on whatever address that
access fetches.
This patch fixes the problem by reading resource array differently based
on whether the 64-bit flag is set, which would indicate PCI glue layer.

Commit a753bfcfdb1f ("intel_th: Make the switch allocate its subdevices")
brings in new subdevice addition/removal logic that's broken for "host
mode": the SWITCH device has no children to begin with, which is not
handled in the code. This results in a null dereference bug later down
the path.
This patch fixes the subdevice removal code to handle host mode correctly.

vsa.console is indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/tty/vt/vt_ioctl.c:711 vt_ioctl() warn: potential spectre issue
'vc_cons' [r]
Fix this by sanitizing vsa.console before using it to index vc_cons
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The function tty_port_tty_get() gets a reference to the tty. Since
the code is not using tty_port_tty_set(), the reference is kept
even after closing the tty.
Avoid using tty_port_tty_get() by directly access the tty instance.
Since lpuart_start_rx_dma() is called from the .startup() and
.set_termios() callback, it is safe to assume the tty instance is
valid.

Apparently, this driver (or the hardware) does not support character
length settings. It's apparently running in 8-bit mode, but it makes
userspace believe it's in 5-bit mode. That makes tcsetattr with CS8
incorrectly fail, breaking e.g. getty from busybox, thus the login shell
on ttyMVx.
Fix by hard-wiring CS8 into c_cflag.

Host prints lots of untracked MMIO at 0x4653c when creating linux guest.
"gvt: vgpu 2: untracked MMIO 0004653c len 4"
GEN9_CLKGATE_DIS_4 (0x4653c) is accessed by i915 for gmbus clockgating.
However vgpu doesn't support any clockgating powergating operations
on related mmio access trap so need add it to default handler.
GEN9_CLKGATE_DIS_4 is accessed in bxt_gmbus_clock_gating() which only
applies to GEN9_LP so doens't show the warning on other platforms.
The solution is to add it to default handler init_bxt_mmio_info().

Recent patch fixed the call trace
"ERROR Port B enabled but PHY powered down? (PHY_CTL 00000000)".
but introduced another similar call trace shown as:
"ERROR Port C enabled but PHY powered down? (PHY_CTL 00000200)".
The call trace will appear when host and guest enabled different ports,
i.e. host using PORT C or neither PORT is enabled, while guest is always
using PORT B as simulated by gvt. The issue is actually covered previously
before the commit and reverals now when the commit do the right thing.
On BXT, some PHY registers are initialized by vbios, before i915 loaded.
Later i915 will re-program some, or skip some based on the implementation.
The initialized mmio for guest i915 is done by gvt, based on the snapshot
taken from host. If host and guest have different PORT enabled, some
DPIO PHY mmios that gvt initialized for guest i915 will not match the
simualted monitor for guest, which leads to guest i915 print the calltrace
when it's trying to enable PHY and PORT.
The solution is to init these DPIO PHY registers to default value, then
guest i915 will program them to reasonable value based on the default
powerwell table and enabled PORT. Together with the old patch, all similar
call trace in guest kernel on BXT can be resolved.
v2: Move PHY register init to intel_vgpu_reset_mmio (Min)
v3: Do not delete empty line in issue fix patch. (zhenyu)

Recent firmware revisions have added the ability to force
these modems to USB2 mode, hiding their SuperSpeed
capabilities from the host. The driver has been using the
SuperSpeed capability, as shown by the bcdUSB field of the
device descriptor, to detect the need to enable the DTR
quirk. This method fails when the modems are forced to
USB2 mode by the modem firmware.
Fix by unconditionally enabling the DTR quirk for the
affected device IDs.

Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the
firmware"), which added the code to mark clocks as CLK_IS_CRITICAL, causes
all unclaimed PMC clocks on Cherry Trail devices to be on all the time,
resulting on the device not being able to reach S0i3 when suspended.
The reason for this commit is that on some Bay Trail / Cherry Trail devices
the r8169 ethernet controller uses pmc_plt_clk_4. Now that the clk-pmc-atom
driver exports an "ether_clk" alias for pmc_plt_clk_4 and the r8169 driver
has been modified to get and enable this clock (if present) the marking of
the clocks as CLK_IS_CRITICAL is no longer necessary.
This commit removes the CLK_IS_CRITICAL marking, fixing Cherry Trail
devices not being able to reach S0i3 greatly decreasing their battery
drain when suspended.

On some boards a platform clock is used as clock for the r8169 chip,
this commit adds support for getting and enabling this clock (assuming
it has an "ether_clk" alias set on it).
This is related to commit d31fd43c0f9a ("clk: x86: Do not gate clocks
enabled by the firmware") which is a previous attempt to fix this for some
x86 boards, but this causes all Cherry Trail SoC using boards to not reach
there lowest power states when suspending.
This commit (together with an atom-pmc-clk driver commit adding the alias)
fixes things properly by making the r8169 get the clock and enable it when
it needs it.

The reason for this commit is that on some Bay Trail / Cherry Trail devices
the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk"
alias, so that the relevant ethernet drivers can try to (optionally) use
this, without needing X86 specific code / hacks, thus fixing ethernet on
these devices without breaking S0i3 support.
This commit uses clkdev_hw_create() to create the alias, mirroring the code
for the already existing "mclk" alias for pmc_plt_clk_3.

the former isn't an accurate representation of whether or not the driver
is actually using atomic modesetting internally (even though it might

Matching network device based on MAC address is problematic
since a non VF network device can be creted with a duplicate MAC
address causing confusion and problems. The VMBus API does provide
a serial number that is a better matching method.

The Hyper-V host API for PCI provides a unique "serial number" which
can be used as basis for sysfs PCI slot table. This can be useful
for cases where userspace wants to find the PCI device based on
serial number.
When an SR-IOV NIC is added, the host sends an attach message
with serial number. The kernel doesn't use the serial number, but
it is useful when doing the same thing in a userspace driver such
as the DPDK. By having /sys/bus/pci/slots/N it provides a direct
way to find the matching PCI device.
There maybe some cases where serial number is not unique such
as when using GPU's. But the PCI slot infrastructure will handle
that.
This has a side effect which may also be useful. The common udev
network device naming policy uses the slot information (rather
than PCI address).

The recent commit to always forward the VF MAC address to the PF for
approval may not work if the PF driver or the firmware is older. This
will cause the VF driver to fail during probe:
bnxt_en 0000:00:03.0 (unnamed net_device) (uninitialized): hwrm req_type 0xf seq id 0x5 error 0xffff
bnxt_en 0000:00:03.0 (unnamed net_device) (uninitialized): VF MAC address 00:00:17:02:05:d0 not approved by the PF
bnxt_en 0000:00:03.0: Unable to initialize mac address.
bnxt_en: probe of 0000:00:03.0 failed with error -99
We fix it by treating the error as fatal only if the VF MAC address is
locally generated by the VF.

The operation ~(p100_inb(VG_LAN_CFG_1) & HP100_LINK_UP) returns a value
that is always non-zero and hence the wait for the link to drop always
terminates prematurely. Fix this by using a logical not operator instead
of a bitwise complement. This issue has been in the driver since
pre-2.6.12-rc2.

Net drivers using phylink shouldn't mess with the link carrier
themselves and should let phylink manage it. The mvpp2 driver wasn't
following this best practice as the mac_config() function made calls to
change the link carrier state. This led to wrongly reported carrier link
state which then triggered other issues. This patch fixes this
behaviour.
But the PPv2 driver relied on this misbehaviour in two cases: for fixed
links and when not using phylink (ACPI mode). The later was fixed by
adding an explicit call to link_up(), which when the ACPI mode will use
phylink should be removed.
The fixed link case was relying on the mac_config() function to set the
link up, as we found an issue in phylink_start() which assumes the
carrier is off. If not, the link_up() function is never called. To fix
this, a call to netif_carrier_off() is added just before phylink_start()
so that we do not introduce a regression in the driver.

pppoe_rcv() needs to look back at the Ethernet header in order to
lookup the PPPoE session. Therefore we need to ensure that the mac
header is big enough to contain an Ethernet header. Otherwise
eth_hdr(skb)->h_source might access invalid data.

While at first mtd_part_of_parse() would just call
of_get_chil_by_name(), it has been patched to deal with sub-partitions
and will now directly manipulate the node returned by mtd_get_of_node()
if the MTD device is a partition.
A of_node_put() was a bit below in the code, to balance the
of_get_child_by_name(). However, despite its name, mtd_get_of_node()
does not take a reference on the OF node. It is a simple helper hiding
some pointer logic to retrieve the OF node related to an MTD
device.
The direct effect of such unbalanced reference counting is visible by
rmmod'ing any module that would have added MTD partitions:
OF: ERROR: Bad of_node_put() on <of_path_to_partition>
As it seems normal to get a reference on the OF node during the
of_property_for_each_string() that follows, add a call to
of_node_get() when relevant.

Currently a scsi device won't contribute to kernel randomness when it uses
blk-mq. Since we commonly use scsi on rotational device with blk-mq, it make
sense to keep contributing to kernel randomness in these cases. This is
especially important for virtual machines.
commit b5b6e8c8d3b4 ("scsi: virtio_scsi: fix IO hang caused by automatic irq
vector affinity") made all virtio-scsi device to use blk-mq, which does not
contribute to randomness today. So for a virtual machine only having
virtio-scsi disk (which is common), it will simple stop getting randomness
from its disks in today's implementation.
With this patch, if the above VM has rotational virtio-scsi device, then it
can still benefit from the entropy generated from the disk.
