The ICH9 is listed as having TCO v2, and indeed the behavior in the
datasheet corresponds to v2 (for example the NO_REBOOT flag is
accessible via the 16KiB-aligned Root Complex Base Address).
However, the TCO counts twice just like in v1; the documentation
of the SECOND_TO_STS bit says: "ICH9 sets this bit to 1 to indicate
that the TIMEOUT bit had been (or is currently) set and a second
timeout occurred before the TCO_RLD register was written. If this
bit is set and the NO_REBOOT config bit is 0, then the ICH9 will
reboot the system after the second timeout. The same can be found
in the BayTrail (Atom E3800) datasheet, and even HOWTOs around
the Internet say that it will reboot after _twice_ the specified
heartbeat.
I did not find the Apollo Lake datasheet, but because v4/v5 has
a SECOND_TO_STS bit just like the previous version I'm enabling
this for Apollo Lake as well.

USB-serial fixes for v4.12-rc2
Here's a fix for a long-standing issue in the ftdi_sio driver that
prevented unprivileged users from updating the low-latency flag,
something which became apparent after a recent change that restored the
older setting of not using low-latency mode by default.
A run of sparse revealed a couple of endianness issues that are now
fixed, and addressed is also a user-triggerable division-by-zero in
io_ti when debugging is enabled.
Finally there are some new device ids, including a simplification of how
we deal with a couple of older Olimex JTAG adapters.
All have been in linux-next with no reported issues.

It makes sense to have a stripped-down defconfig for just Gemini, as
it is a pretty small platform used in NAS etc, and will use appended
device tree. It is also quick to compile and test. Hopefully this
defconfig can be a good base for distributions such as OpenWRT.
I plan to add in the config options needed for the different
variants of Gemini as we go along.

We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.
Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.
As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.
Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.
As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

virt_addr_valid() is supposed to tell you if it's OK to call virt_to_page() on
an address. What this means in practice is that it should only return true for
addresses in the linear mapping which are backed by a valid PFN.
We are failing to properly check that the address is in the linear mapping,
because virt_to_pfn() will return a valid looking PFN for more or less any
address. That bug is actually caused by __pa(), used in virt_to_pfn().
eg: __pa(0xc000000000010000) = 0x10000 # Good
__pa(0xd000000000010000) = 0x10000 # Bad!
__pa(0x0000000000010000) = 0x10000 # Bad!
This started happening after commit bdbc29c19b26 ("powerpc: Work around gcc
miscompilation of __pa() on 64-bit") (Aug 2013), where we changed the definition
of __pa() to work around a GCC bug. Prior to that we subtracted PAGE_OFFSET from
the value passed to __pa(), meaning __pa() of a 0xd or 0x0 address would give
you something bogus back.
Until we can verify if that GCC bug is no longer an issue, or come up with
another solution, this commit does the minimal fix to make virt_addr_valid()
work, by explicitly checking that the address is in the linear mapping region.

of validity before freeing the counter.

In case of disabled counters the entry index will be incorrect. Fix this
by moving the entry index set before the counter status check.

This patch fixes several issues:
- if the 1st 'kzalloc' fails, we dereference a NULL pointer
- if the 2nd 'kzalloc' fails, there is a memory leak
- if 'sysfs_create_bin_file' fails there is also a memory leak
Fix it by adding a test after the first memory allocation and some error
handling paths to correctly free memory if needed.

drm_of_find_panel_or_bridge() is expecting np to point to the encoder
node, not the bridge or panel this encoder is feeding.
Moreover, the endpoint parameter passed to drm_of_find_panel_or_bridge()
is always set to zero, which prevents us from probing all outputs.
We also move the atmel_hlcdc_rgb_output allocation after the
panel/bridge detection to avoid useless allocations.

/dev/mem currently allows mmap() mappings that wrap around the end of
the physical address space, which should probably be illegal. It
circumvents the existing STRICT_DEVMEM permission check because the loop
immediately terminates (as the start address is already higher than the
end address). On the x86_64 architecture it will then cause a panic
(from the BUG(start >= end) in arch/x86/mm/pat.c:reserve_memtype()).
This patch adds an explicit check to make sure offset + size will not
wrap around in the physical address type.

When IOMMU_IOVA is not built-in but host1x is, we get a link error:
drivers/gpu/host1x/dev.o: In function `host1x_remove':
dev.c:(.text.host1x_remove+0x50): undefined reference to `put_iova_domain'
drivers/gpu/host1x/dev.o: In function `host1x_probe':

dev.c:(.text.host1x_probe+0x38c): undefined reference to `put_iova_domain'

drivers/gpu/host1x/cdma.o: In function `host1x_cdma_deinit':

This adds the same select statement that we have for drm_tegra.

In their infinite wisdom, and never ending quest for end user frustration,
Lenovo has decided to use a new USB device ID for the wwan modules in
their 2017 laptops. The actual hardware is still the Sierra Wireless
EM7455 or EM7430, depending on region.
