This driver adds support for Infineon's new SLB 9645 TT 1.2 I2C TPMs,
which supports clockstretching, combined reads and a bus speed of
up to 400khz. The device also has a new device id.
The driver works now also fine with device trees, so you can
instantiate your device by adding:
+ tpm {
+ compatible = "infineon,slb9645tt";
+ reg = <0x20>;
+ };
for SLB 9645 devices or
+ tpm {
+ compatible = "infineon,slb9635tt";
+ reg = <0x20>;
+ };
for SLB 9635 devices
to your device tree.
tpm_i2c_infineon is also retained as a compatible id as a fallback to
slb9635 protocol.
The driver was tested on Beaglebone.

Convert the struct i2c_msg initialization to C99 format. This makes

The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data. Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

Pull virtio fixes from Rusty Russell:
"One reversion, a tiny leak fix, and a cc:stable locking fix, in two
parts"
* tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
virtio: console: add locking around c_ovq operations
virtio: console: rename cvq_lock to c_ivq_lock
hw_random: free rng_buffer at module exit
Revert "virtio_console: Initialize guest_connected=true for rproc_serial"
|
|
When multiple ovq operations are being performed (lots of open/close
operations on virtio_console fds), the __send_control_msg() function can
get confused without locking.
A simple recipe to cause badness is:
* create a QEMU VM with two virtio-serial ports
* in the guest, do
while true;do echo abc >/dev/vport0p1;done
while true;do echo edf >/dev/vport0p2;done
In one run, this caused a panic in __send_control_msg(). In another, I
got
virtio_console virtio0: control-o:id 0 is not a head!
This also results repeated messages similar to these on the host:
qemu-kvm: virtio-serial-bus: Unexpected port id 478762112 for device virtio-serial-bus.0
qemu-kvm: virtio-serial-bus: Unexpected port id 478762368 for device virtio-serial-bus.0

The cvq_lock was taken for the c_ivq. Rename the lock to make that
obvious.
We'll also add a lock around the c_ovq in the next commit, so there's no

ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs
This patch series covers both ASoC and extcon subsystems and fixes an

really shouldn't run HPDET while the headphone is active. The first
patch is a refactoring to make the extcon side easier.

virtio_rng feeds the randomness buffer handed by the core directly
into the scatterlist, since commit bb347d98079a547e80bd4722dee1de61e4dca0e8.
However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address
(at least on most archs). We could fix this in virtio_rng, but it's actually
far easier to just do it in the core as virtio_rng would have to allocate
a buffer every time (it doesn't know how much the core will want to read).

Commit 6133705494bb introduced a circular lock dependency because
posix_cpu_timers_exit() is called by release_task(), which is holding
a writer lock on tasklist_lock, and this can cause a deadlock since
kill_fasync() gets called with nonblocking_pool.lock taken.
There's no reason why kill_fasync() needs to be taken while the random
pool is locked, so move it out to fix this locking dependency.

The configuration change building ipmi_si into the kernel precludes the
use of a custom driver that can utilize more than one KCS interface,
multiple IPMBs, and more than one BMC. This capability is important for
fault-tolerant systems.
Even if the kernel option ipmi_si.trydefaults=0 is specified, ipmi_si
discovers and claims one of the KCS interfaces on a Stratus server. The
inability to now prevent the kernel from managing this device is a
regression from previous kernels. The regression breaks a capability
fault-tolerant vendors have relied upon.
To support both ACPI opregion access and the need to avoid activation of
ipmi_si on some platforms, we've added two new kernel options,
ipmi_si.tryacpi and ipmi_si.trydmi be added to prevent ipmi_si from
initializing when these options are set to 0 on the kernel command line.
With these options at the default value of 1, ipmi_si init proceeds
according to the kernel default.

The static lock initializers want to be fed the proper name of the
lock and not some random string. In mainline random strings are
obfuscating the readability of debug output, but for RT they prevent
the spinlock substitution. Fix it up.

When I refactored the code initially, I forgot that gen2 uses a
different bar for the CPU mappable aperture. The agp-less code knows
nothing of generations less than 5, so we have to expand the gtt_probe
function to include the mappable base and end.
It was originally broken by me:

When rproc_serial is initialized, guest_connected should be set
to true. We can then revert the extra checks introduced in
commit: "virtio_console: Let unconnected rproc device receive data."

Use virtio device index for creating unique device port names.
Current index allocation in virtio is based on a monotonically
increasing variable "index". A better handling of this is to
use device index which is allocated by ida.

mgslpc_probe() ignores errors in mgslpc_add_device() and
does not release all resource if mgslpc_config() failed.
The patch adds returned code to mgslpc_add_device()
and fixes the both issues.

Don't access uninitialized work-queue when removing device.
The work queue is initialized only if the device multi-queue.
So don't call cancel_work unless this is a multi-queue device.
This fixes the following panic:
