commit f3122a79a1b0a113d3aea748e0ec26f2cb2889de upstream.
arch_update_cpu_topology is first called from:
kernel_init_freeable->sched_init_smp->sched_init_domains
even before cpus has been registered in:
kernel_init_freeable->do_one_initcall->s390_smp_init
Do not trigger kobject_uevent change events until cpu devices are
actually created. Fixes the following kasan findings:

commit fe55e770327363304c4111423e6f7ff3c650136d upstream.
when the battery is set to sbs-mode and no gpio detection is enabled
"health" is always returning a value even when the battery is not present.
All other fields return "not present".
This leads to a scenario where the driver is constantly switching between
"present" and "not present" state. This generates a lot of constant
traffic on the i2c.
This commit changes the response of "health" to an error when the battery
is not responding leading to a consistent "not present" state.

commit 76a95bd8f9e10cade9c4c8df93b5c20ff45dc0f5 upstream.
When ccree driver runs it checks the state of the Trusted Execution
Environment CryptoCell driver before proceeding. We did not account
for cases where the TEE side is not ready or not available at all.
Fix it by only considering TEE error state after sync with the TEE
side driver.

commit 56090a3902c80c296e822d11acdb6a101b322c52 upstream.
pnv_tce() returns a pointer to a TCE entry and originally a TCE table
would be pre-allocated. For the default case of 2GB window the table
needs only a single level and that is fine. However if more levels are
requested, it is possible to get a race when 2 threads want a pointer
to a TCE entry from the same page of TCEs.
This adds cmpxchg to handle the race. Note that once TCE is non-zero,
it cannot become zero again.

commit b1f373a11d25fc9a5f7679c9b85799fe09b0dc4a upstream.
VAG power control is improved to fit the manual [1]. This patch fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot,
the VAG power remains off that leads to poor sound quality from line-in.
I.e. after boot:
- Connect sound source to Line-In jack;
- Connect headphone to HP jack;
- Run following commands:
$ amixer set 'Headphone' 80%
$ amixer set 'Headphone Mux' LINE_IN
Change VAG power on/off control according to the following algorithm:
- turn VAG power ON on the 1st incoming event.
- keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In).
- turn VAG power OFF when there is the latest consumer's pre-down event
come.
- always delay after VAG power OFF to avoid pop.
- delay after VAG power ON if the initiative consumer is Line-In, this
prevents pop during line-in muxing.
According to the data sheet [1], to avoid any pops/clicks,
the outputs should be muted during input/output
routing changes.

When calling thermal_add_hwmon_sysfs(), the device type is sanitized by
replacing '-' with '_'. However tz->type remains unsanitized. Thus
calling thermal_hwmon_lookup_by_type() returns no device. And if there is
no device, thermal_remove_hwmon_sysfs() fails with "hwmon device lookup
failed!".
The result is unregisted hwmon devices in the sysfs.

From: Igor Druzhinin <[email protected]>
[ Upstream commit a4098bc6eed5e31e0391bcc068e61804c98138df ]
If MCFG area is not reserved in E820, Xen by default will defer its usage
until Dom0 registers it explicitly after ACPI parser recognizes it as
a reserved resource in DSDT. Having it reserved in E820 is not
mandatory according to "PCI Firmware Specification, rev 3.2" (par. 4.1.2)
and firmware is free to keep a hole in E820 in that place. Xen doesn't know
what exactly is inside this hole since it lacks full ACPI view of the
platform therefore it's potentially harmful to access MCFG region
without additional checks as some machines are known to provide
inconsistent information on the size of the region.
Now xen_mcfg_late() runs after acpi_init() which is too late as some basic
PCI enumeration starts exactly there as well. Trying to register a device
prior to MCFG reservation causes multiple problems with PCIe extended
capability initializations in Xen (e.g. SR-IOV VF BAR sizing). There are
no convenient hooks for us to subscribe to so register MCFG areas earlier
upon the first invocation of xen_add_device(). It should be safe to do once
since all the boot time buses must have their MCFG areas in MCFG table
already and we don't support PCI bus hot-plug.

integrity_kernel_read() returns the number of bytes read. If this is
a short read then this positive value is returned from
ima_calc_file_hash_atfm(). Currently this is only indirectly called from
ima_calc_file_hash() and this function only tests for the return value
being zero or nonzero and also doesn't forward the return value.
Nevertheless there's no point in returning a positive value as an error,
so translate a short read into -EINVAL.

commit 3ca94192278ca8de169d78c085396c424be123b3 upstream.

When CR4.UMIP is set, guest should have UMIP cpuid flag. Current
kvm set_sregs function doesn't have such check when userspace inputs
sregs values. SECONDARY_EXEC_DESC is enabled on writes to CR4.UMIP
in vmx_set_cr4 though guest doesn't have UMIP cpuid flag. The testcast
triggers handle_desc warning when executing ltr instruction since
guest architectural CR4 doesn't set UMIP. This patch fixes it by
adding valid CR4 and CPUID combination checking in __set_sregs.

commit 82a2f88458d70704be843961e10b5cef9a6e95d3 upstream.
The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.
Add 'tr "w" "W"' to merge the two and not worry about the ordering.

commit e9e006f5fcf2bab59149cb38a48a4817c1b538b4 upstream.
This fixes a bug added in 4.10 with commit:
commit 9561a7ade0c205bc2ee035a2ac880478dcc1a024
Author: Josef Bacik <[email protected]>
Date: Tue Nov 22 14:04:40 2016 -0500
nbd: add multi-connection support
that limited the number of devices to 256. Before the patch we could
create 1000s of devices, but the patch switched us from using our
own thread to using a work queue which has a default limit of 256
active works.
The problem is that our recv_work function sits in a loop until
disconnection but only handles IO for one connection. The work is
started when the connection is started/restarted, but if we end up
creating 257 or more connections, the queue_work call just queues
connection257+'s recv_work and that waits for connection 1 - 256's
recv_work to be disconnected and that work instance completing.
Instead of reverting back to kthreads, this has us allocate a
workqueue_struct per device, so we can block in the work.
