commit 8b572a4200828b4e75cc22ed2f494b58d5372d65 upstream.
In needs_ilk_vtd_wa(), we pass in the GPU device but compared it against
the ids for the mobile GPU and the mobile host bridge. That latter is
impossible and so likely was just a typo for the desktop GPU device id
(which is also buggy).

commit 9d75f08946e8485109458ccf16f714697c207f41 upstream.
tpm_ibmvtpm_probe() calls ibmvtpm_reset_crq(ibmvtpm) without having yet
set the virtual device in the ibmvtpm structure. So in ibmvtpm_reset_crq,
the phype call contains empty unit addresses, ibmvtpm->vdev->unit_address.

commit 62dfd912ab3b5405b6fe72d0135c37e9648071f1 upstream.
Problem: When IMA and VTPM are both enabled in kernel config,
kernel hangs during bootup on LE OS.
Why?: IMA calls tpm_pcr_read() which results in tpm_ibmvtpm_send
and tpm_ibmtpm_recv getting called. A trace showed that
tpm_ibmtpm_recv was hanging.
Resolution: tpm_ibmtpm_recv was hanging because tpm_ibmvtpm_send
was sending CRQ message that probably did not make much sense
to phype because of Endianness. The fix below sends correctly
converted CRQ for LE. This was not caught before because it
seems IMA is not enabled by default in kernel config and
IMA exercises this particular code path in vtpm.
Tested with IMA and VTPM enabled in kernel config and VTPM
enabled on both a BE OS and a LE OS ppc64 lpar. This exercised
CRQ and TPM command code paths in vtpm.
Patch is against Peter's tpmdd tree on github which included
Vicky's previous vtpm le patches.

commit eb71f8a5e33fa1066fb92f0111ab366a341e1f6c upstream.
The tpm_ibmvtpm module is affected by an unaligned access problem.
ibmvtpm_crq_get_version failed with rc=-4 during boot when vTPM is
enabled in Power partition, which supports both little endian and
big endian modes.
We added little endian support to fix this problem:
1) added cpu_to_be64 calls to ensure BE data is sent from an LE OS.
2) added be16_to_cpu and be32_to_cpu calls to make sure data received
is in LE format on a LE OS.

commit 1ba3b0b6f218072afe8372d12f1b6bf26a26008e upstream.
When sending data in tpm_stm_i2c_send, each loop iteration send buf.
Send buf + i instead as the goal of this for loop is to send a number
of byte from buf that fit in burstcnt. Once those byte are sent, we are
supposed to send the next ones.
The driver was working because the burstcount value returns always the maximum size for a TPM
command or response. (0x800 for a command and 0x400 for a response).

commit 84eb186bc37c0900b53077ca21cf6dd15823a232 upstream.
There was an oops in tpm_ibmvtpm_get_desired_dma, which caused
kernel panic during boot when vTPM is enabled in Power partition
configured in AMS mode.
vio_bus_probe calls vio_cmo_bus_probe which calls
tpm_ibmvtpm_get_desired_dma to get the size needed for DMA allocation.
The problem is, vio_cmo_bus_probe is called before calling probe, which
for vtpm is tpm_ibmvtpm_probe and it's this function that initializes
and sets up vtpm's CRQ and gets required data values. Therefore,
since this has not yet been done, NULL is returned in attempt to get
the size for DMA allocation.
We added a NULL check. In addition, a default buffer size will
be set when NULL is returned.

commit 448e9c55c12d6bd4fa90a7e31d802e045666d7c8 upstream.
Some machines, such as the Acer C720 and Toshiba CB35, have TPMs that do
not send IRQs while also having an ACPI TPM entry indicating that they
will be sent. These machines freeze on resume while the tpm_tis module
waits for an IRQ, eventually timing out.
When in interrupt mode, the tpm_tis module should receive an IRQ during
module init. Fall back to polling mode if none is received when expected.

commit 24c65bc7037e7d0f362c0df70d17dd72ee64b8b9 upstream.
The add_early_randomness() function in drivers/char/hw_random/core.c passes
a 16-byte buffer to pseries_rng_data_read(). Unfortunately, plpar_hcall()
returns four 64-bit values and trashes 16 bytes on the stack.
This bug has been lying around for a long time. It got unveiled by:
commit d3cc7996473a7bdd33256029988ea690754e4e2a
Author: Amit Shah <amit.shah@redhat.com>

hwrng: fetch randomness only after device init
It may trig a oops while loading or unloading the pseries-rng module for both
PowerVM and PowerKVM guests.
This patch does two things:
- pass an intermediate well sized buffer to plpar_hcall(). This is acceptalbe
since we're not on a hot path.
- move to the new read API so that we know the return buffer size for sure.

commit d4c5efdb97773f59a2b711754ca0953f24516739 upstream.
zatimend has reported that in his environment (3.16/gcc4.8.3/corei7)
memset() calls which clear out sensitive data in extract_{buf,entropy,
entropy_user}() in random driver are being optimized away by gcc.
Add a helper memzero_explicit() (similarly as explicit_bzero() variants)
that can be used in such cases where a variable with sensitive data is
being cleared out in the end. Other use cases might also be in crypto
code. [ I have put this into lib/string.c though, as it's always built-in
and doesn't need any dependencies then. ]

commit f07a5e9a331045e976a3d317ba43d14859d9407c upstream.
Most device drivers do call 'tpm_do_selftest' which executes a
TPM_ContinueSelfTest. tpm_i2c_stm_st33 is just pointlessly different,
I think it is bug.
These days we have the general assumption that the TPM is usable by
the kernel immediately after the driver is finished, so we can no
longer defer the mandatory self test to userspace.

commit 6d827fbcc370ca259a2905309f64161ab7b10596 upstream.
Commit f36fdb9f0266 (i8k: Force SMM to run on CPU 0) adds support
for multi-core CPUs to the driver. Unfortunately, that causes it
to fail loading if compiled without SMP support, at least on
32 bit kernels. Kernel log shows "i8k: unable to get SMM Dell
signature", and function i8k_smm is found to return -EINVAL.
Testing revealed that the culprit is the missing return value check
of set_cpus_allowed_ptr.

commit f759546498d820670934c901a2fdf1ce948d2e5c upstream.
Chromebooks (at least Acer C720 and Pixel) implement an ACPI object
for TPM, but don't implement the _DSM method to support PPI. As
a result, the TPM driver fails to load on those machines after
commit 1569a4c4ceba (ACPI / TPM: detect PPI features by checking
availability of _DSM functions) which causes them to fail to
resume from system suspend, becuase they require the TPM hardware
to be put into the right state during resume and the TPM driver
is necessary for that.
Fix the problem by making tpm_add_ppi() return 0 when tpm_ppi_handle
is still NULL after walking the ACPI namespace in search for the PPI
_DSM, which allows the TPM driver to load and operate the hardware
(during system resume in particular), but avoid creating the PPI
sysfs group in that case.
This change is based on a prototype patch from Jiang Liu.
Fixes: 1569a4c4ceba (ACPI / TPM: detect PPI features by checking availability of _DSM functions)

commit 48e8ac2979920ffa39117e2d725afa3a749bfe8d upstream.
With recent changes it is possible for the timer handler to detect an
idle interface and not start the timer, but the thread to start an
operation at the same time. The thread will not start the timer in that
instance, resulting in the timer not running.
Instead, move all timer operations under the lock and start the timer in
the thread if it detect non-idle and the timer is not already running.
Moving under locks allows the last timeout to be set in both the thread
and the timer. 'Timer is not running' means that the timer is not
pending and smi_timeout() is not running. So we need a flag to detect
this correctly.
Also fix a few other timeout bugs: setting the last timeout when the
interrupt has to be disabled and the timer started, and setting the last
timeout in check_start_timer_thread possibly racing with the timer

While we are at it, don't do kmap() under kmap_atomic(), *especially*
for a page we'd allocated with GFP_KERNEL. It's spelled "page_address",
and had that been more than that, we'd have a real trouble - kmap_high()
can block, and doing that while holding kmap_atomic() is a Bad Idea(tm).

The Kconfig symbol MAX_RAW_DEVS is meant to be between 1 and 65536. But
those boundaries are not enforced by its Kconfig entry.
Note that MAX_RAW_DEVS is used to set MAX_RAW_MINORS in
drivers/char/raw.c. If one would accidentally set MAX_RAW_DEVS to an
invalid value, that invalid value will actually end up being used in
raw_init().
So add an appropriate range to this Kconfig entry.

bind_get() checks the device number it is called with. It uses
MAX_RAW_MINORS for the upper bound. But MAX_RAW_MINORS is set at compile
time while the actual number of raw devices can be set at runtime. This
means the test can either be too strict or too lenient. And if the test
ends up being too lenient bind_get() might try to access memory beyond
what was allocated for "raw_devices".
So check against the runtime value (max_raw_minors) in this function.

Loading ipmi_si module while bmc is disconnected, we found the timeout
is longer than 5 secs. Actually it takes about 3 mins and 20
secs.(HZ=250)
error message as below:
Dec 12 19:08:59 linux kernel: IPMI BT: timeout in RD_WAIT [ ] 1 retries left
Dec 12 19:08:59 linux kernel: BT: write 4 bytes seq=0x01 03 18 00 01
[...]
Dec 12 19:12:19 linux kernel: IPMI BT: timeout in RD_WAIT [ ]
Dec 12 19:12:19 linux kernel: failed 2 retries, sending error response
Dec 12 19:12:19 linux kernel: IPMI: BT reset (takes 5 secs)
Dec 12 19:12:19 linux kernel: IPMI BT: flag reset [ ]
Function wait_for_msg_done() use schedule_timeout_uninterruptible(1) to
sleep 1 tick, so we should subtract jiffies_to_usecs(1) instead of 100
usecs from timeout.

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.
- On top of the above, new sysfs attribute for ACPI device objects
allowing user space to check device status by triggering the
execution of _STA for its ACPI object. From Srinivas Pandruvada.
- ACPI core hotplug changes reducing code duplication, integrating
the PCI root hotplug with the core and reworking container hotplug.
- ACPI core simplifications making it use ACPI_COMPANION() in the
code "glueing" ACPI device objects to "physical" devices.
- ACPICA update to upstream version 20131218. This adds support for
the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves
debug facilities. From Bob Moore, Lv Zheng and Betty Dall.
- Init code change to carry out the early ACPI initialization
earlier. That should allow us to use ACPI during the timekeeping
initialization and possibly to simplify the EFI initialization too.
From Chun-Yi Lee.
- Clenups of the inclusions of ACPI headers in many places all over
from Lv Zheng and Rashika Kheria (work in progress).
- New helper for ACPI _DSM execution and rework of the code in
drivers that uses _DSM to execute it via the new helper. From
Jiang Liu.
- New Win8 OSI blacklist entries from Takashi Iwai.
- Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun
Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava,
Rashika Kheria, Tang Chen, Zhang Rui.

from Dirk Brandewie and intel_pstate documentation from Ramkumar
Ramachandra.
- Generic CPU boost ("turbo") support for cpufreq from Lukasz
Majewski.
- powernow-k6 cpufreq driver fixes from Mikulas Patocka.

Pull Xen updates from Konrad Rzeszutek Wilk:
"Two major features that Xen community is excited about:
The first is event channel scalability by David Vrabel - we switch
over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
queue with priorities. This lets us be able to handle more events,
have lower latency, and better scalability. Good stuff.
The other is PVH by Mukesh Rathor. In short, PV is a mode where the
kernel lets the hypervisor program page-tables, segments, etc. With
EPT/NPT capabilities in current processors, the overhead of doing this
in an HVM (Hardware Virtual Machine) container is much lower than the
hypervisor doing it for us.
In short we let a PV guest run without doing page-table, segment,
syscall, etc updates through the hypervisor - instead it is all done
within the guest container. It is a "hybrid" PV - hence the 'PVH'
name - a PV guest within an HVM container.
The major benefits are less code to deal with - for example we only
use one function from the the pv_mmu_ops (which has 39 function
calls); faster performance for syscall (no context switches into the
hypervisor); less traps on various operations; etc.
It is still being baked - the ABI is not yet set in stone. But it is
pretty awesome and we are excited about it.
Lastly, there are some changes to ARM code - you should get a simple
conflict which has been resolved in #linux-next.
In short, this pull has awesome features.
Features:
- FIFO event channels. Key advantages: support for over 100,000
events (2^17), 16 different event priorities, improved fairness in
event latency through the use of FIFOs.
- Xen PVH support. "It’s a fully PV kernel mode, running with
paravirtualized disk and network, paravirtualized interrupts and
timers, no emulated devices of any kind (and thus no qemu), no BIOS
or legacy boot — but instead of requiring PV MMU, it uses the HVM
hardware extensions to virtualize the pagetables, as well as system
calls and other privileged operations." (from "The
Paravirtualization Spectrum, Part 2: From poles to a spectrum")
Bug-fixes:
- Fixes in balloon driver (refactor and make it work under ARM)
- Allow xenfb to be used in HVM guests.
- Allow xen_platform_pci=0 to work properly.
- Refactors in event channels"

Conflicts are getting out of hand, and now we have to shuffle even
more in -next which was also shuffled in -fixes (the call for
drm_mode_config_reset needs to move yet again).
So do a proper backmerge. I wanted to wait with this for the 3.13
relaese, but alas let's just do this now.
Conflicts:
drivers/gpu/drm/i915/i915_reg.h
drivers/gpu/drm/i915/intel_ddi.c
drivers/gpu/drm/i915/intel_display.c
drivers/gpu/drm/i915/intel_pm.c
Besides the conflict around the forcewake get/put (where we chaged the
called function in -fixes and added a new parameter in -next) code all
the current conflicts are of the adjacent lines changed type.

The TTY_PRINTK option is bool, and hence this code is either
present or absent. It will never be modular, so using
module_init as an alias for __initcall is rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
