Here is the big tty/serial driver patchset for 4.11-rc1.
Not much here, but a lot of little fixes and individual serial driver
updates all over the subsystem. Majority are for the sh-sci driver and
platform (the arch-specific changes have acks from the maintainer).
The start of the "serial bus" code is here as well, but nothing is
converted to use it yet. That work is still ongoing, hopefully will
start to show up across different subsystems for 4.12 (bluetooth is one
major place that will be used.)
All of these have been in linux-next for a while with no reported
issues.

Unlike the device driver support for TPM 1.2, the TPM 2.0 does
not support the securityfs pseudo files for displaying the

This patch enables support for providing the TPM 2.0 event log in

records multiple digests, which is different from TPM 1.2. This
patch enables the tpm_bios_log_setup for TPM 2.0 and adds the

The current TPM 2.0 device driver extends only the SHA1 PCR bank
but the TCG Specification[1] recommends extending all active PCR
banks, to prevent malicious users from setting unused PCR banks with
fake measurements and quoting them.
The existing in-kernel interface(tpm_pcr_extend()) expects only a
SHA1 digest. To extend all active PCR banks with differing
digest sizes, the SHA1 digest is padded with trailing 0's as needed.
This patch reuses the defined digest sizes from the crypto subsystem,
adding a dependency on CRYPTO_HASH_INFO module.

For a long time the cdev read/write interface had this strange
idea that userspace had to read the result within 60 seconds otherwise
it is discarded. Perhaps this made sense under some older locking regime,
but in the modern kernel it is not required and is just dangerous.
Since something may be relying on this, double the timeout and print a
warning. We can remove the code in a few years, but this should be
enough to prevent new users.

The serdev bus is designed for devices such as Bluetooth, WiFi, GPS
and NFC connected to UARTs on host processors. Tradionally these have
been handled with tty line disciplines, rfkill, and userspace glue such
as hciattach. This approach has many drawbacks since it doesn't fit
into the Linux driver model. Handling of sideband signals, power control
and firmware loading are the main issues.
This creates a serdev bus with controllers (i.e. host serial ports) and
attached devices. Typically, these are point to point connections, but
some devices have muxing protocols or a h/w mux is conceivable. Any
muxing is not yet supported with the serdev bus.

Since commit 1107d065fd ("tpm_tis: Introduce intermediate layer for
TPM access") Atmel 3203 TPM on ThinkPad X61S (TPM firmware version 13.9)
no longer works. The initialization proceeds fine until we get and
start using chip-reported timeouts - and the chip reports C and D
timeouts of zero.
It turns out that until commit 8e54caf407 ("tpm: Provide a generic
means to override the chip returned timeouts") we had actually let
default timeout values remain in this case, so let's bring back this
behavior to make chips like Atmel 3203 work again.
Use a common code that was introduced by that commit so a warning is
printed in this case and /sys/class/tpm/tpm*/timeouts correctly says the
timeouts aren't chip-original.

When borrowing the pfn_valid() check from mmap_kmem(), somebody managed
to get physical and virtual addresses spectacularly muddled up, such
that we've ended up with checks for one being the other. Whilst this
does indeed prevent out-of-bounds accesses crashing, on most systems
it also prevents the more desirable use-case of working at all ever.
Check the *virtual* offset correctly for what it is. Furthermore, do
so in the right place - a read or write may span multiple pages, so a
single up-front check is insufficient. High memory accesses already
have a similar validity check just before the copy_to_user() call, so
just make the low memory path fully consistent with that.

This includes the new virtio crypto device, and fixes all over the

found some bugs which this fixes. And it appears that everyone is in
agreement that disabling endian-ness sparse checks shouldn't be
necessary any longer.
So this enables them for everyone, and drops __CHECK_ENDIAN__
and __bitwise__ APIs.
IRQ handling in virtio has been refactored somewhat, the
larger switch to IRQ_SHARED will have to wait as

"virtio, vhost: new device, fixes, speedups
This includes the new virtio crypto device, and fixes all over the
place. In particular enabling endian-ness checks for sparse builds
found some bugs which this fixes. And it appears that everyone is in
agreement that disabling endian-ness sparse checks shouldn't be
necessary any longer.
So this enables them for everyone, and drops the __CHECK_ENDIAN__ and
__bitwise__ APIs.
IRQ handling in virtio has been refactored somewhat, the larger switch
to IRQ_SHARED will have to wait as it proved too aggressive"

vsock: lookup and setup guest_cid inside vhost_vsock_lock

virtio_pci: merge vp_free_vectors into vp_del_vqs
...
struct ports_device includes a config field including the whole
virtio_console_config, but only max_nr_ports in there is ever updated or
used. The rest is unused and in fact does not even mirror the
device config. Drop everything except max_nr_ports,
saving some memory.

convertion printk() to pr_xxx() and removal of an unused module
parameter. Some small bug fixes and enhancements.
This also adds a post softdep from the IPMI core module to the
IPMI device interface. Many people have complained that the device
interface isn't automatically avaiable when IPMI is loaded. I don't
want to make the device interface mandatory, though, plenty of people
use IPMI internally (like with ACPI) and don't need a device interface
or the added possible security entry. A softdep should make it work
"out of the box" but allow people to not have it if they don't want it.

Merge more updates from Andrew Morton:
- a few misc things
- kexec updates
- DMA-mapping updates to better support networking DMA operations
- IPC updates
- various MM changes to improve DAX fault handling
- lots of radix-tree changes, mainly to the test suite. All leading up
to reimplementing the IDA/IDR code to be a wrapper layer over the
radix-tree. However the final trigger-pulling patch is held off for
4.11.

radix tree test suite: delete unused rcupdate.c

radix-tree: ensure counts are initialised

idr_find_slowpath() is not intended to be part of the public API, it's
an implementation detail. There's no reason to skip straight to the
slowpath here.

Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety. Just use masked
vmf->address which already has the appropriate type.
