I'm not sure what the objection is here?  There is an argument to this
this function named "free_conn" which determines if the structure should
be freed, or if the network connection is just being torn down and
reconnected.

[PATCH v3 6/7] x86/kvm: pass stable clocksource to guests when running nested on Hyper-V

[Vitaly Kuznetsov]

Currently, KVM is able to work in 'masterclock' mode passing
PVCLOCK_TSC_STABLE_BIT to guests when the clocksource we use on the host
is TSC. When running nested on Hyper-V we normally use a different one:
TSC page which is resistant to TSC frequency changes on event like L1
migration. Add support for it in KVM.

The only non-trivial change in the patch is in vgettsc(): when updating
our gtod copy we now need to get both the clockread and tsc value.

[PATCH v3 7/7] x86/kvm: support Hyper-V reenlightenment

[Vitaly Kuznetsov]

When we run nested KVM on Hyper-V guests we need to update masterclocks for
all guests when L1 migrates to a host with different TSC frequency.
Implement the procedure in the following way:
- Pause all guests.
- Tell our host (Hyper-V) to stop emulating TSC accesses.
- Update our gtod copy, recompute clocks.
- Unpause all guests.

This is somewhat similar to cpufreq but we have two important differences:
we can only disable TSC emulation globally (on all CPUs) and we don't know
the new TSC frequency until we turn the emulation off so we can't
'prepare' ourselves to the event.

[PATCH v3 2/7] x86/hyper-v: add a function to read both TSC and TSC page value simulateneously

[Vitaly Kuznetsov]

This is going to be used from KVM code where we need to get both
TSC and TSC page value.

Nobody is supposed to use the function when Hyper-V code is compiled out,
just BUG().

[PATCH v3 4/7] x86/hyper-v: redirect reenlightment notifications on CPU offlining

[Vitaly Kuznetsov]

It is very unlikely for CPUs to get offlined when we run on Hyper-V as
we have a protection in vmbus module which prevents it when we have any
VMBus devices assigned. This, however,  may change in future if an option
to reassign an already active channel will be added. It is also possible
to run without any Hyper-V devices of have a CPU with no assigned channels.

Reassign reenlightenment notifications to some other active CPU when
the CPU which is assigned to get them goes offline.

[PATCH v3 3/7] x86/hyper-v: reenlightenment notifications support

[Vitaly Kuznetsov]

Hyper-V supports Live Migration notification. This is supposed to be used
in conjunction with TSC emulation: when we are migrated to a host with
different TSC frequency for some short period host emulates our accesses
to TSC and sends us an interrupt to notify about the event. When we're
done updating everything we can disable TSC emulation and everything will
start working fast again.

We didn't need these notifications before as Hyper-V guests are not
supposed to use TSC as a clocksource: in Linux we even mark it as unstable
on boot. Guests normally use 'tsc page' clocksouce and host updates its
values on migrations automatically.

Things change when we want to run nested virtualization: even when we pass
through PV clocksources (kvm-clock or tsc page) to our guests we need to
know TSC frequency and when it changes.

Hyper-V Top Level Functional Specification (as of v5.0b) wrongly specifies
EAX:BIT(12) of CPUID:0x4009 as the feature identification bit. The
right one to check is EAX:BIT(13) of CPUID:0x4003. I was assured that
the fix in on the way.

[PATCH v3 0/7] x86/kvm/hyperv: stable clocksorce for L2 guests when running nested KVM on Hyper-V

[Vitaly Kuznetsov]

Changes since v2:
- Add Paolo's Acked-by to PATCH6-7
- Add Thomas' Reviewed-by to PATCH1
- Update the description of PATCH2 to match the reality [Thomas Gleixner]
- Add __visible and __irq_entry annotations to hyperv_reenlightenment_intr()
  [Thomas Gleixner]
- Drop spinlock protection and use cpumask_any_but() in PATCH4
  [Thomas Gleixner]

Original description:

Currently, KVM passes PVCLOCK_TSC_STABLE_BIT to its guests when running in
so called 'masterclock' mode and this is only possible when the clocksource
on the host is TSC. When running nested on Hyper-V we're using a different
clocksource in L1 (Hyper-V TSC Page) which can actually be used for
masterclock. This series brings the required support.

Making KVM work with TSC page clocksource is relatively easy, it is done in
PATCH 6 of the series. All the rest is required to support L1 migration
when TSC frequency changes, we use a special feature from Hyper-V to do
the job.

Vitaly Kuznetsov (7):
  x86/hyper-v: check for required priviliges in hyperv_init()
  x86/hyper-v: add a function to read both TSC and TSC page value
simulateneously
  x86/hyper-v: reenlightenment notifications support

[PATCH] staging: lustre: Fix avoid intensive reconnecting for ko2iblnd patch

[Eremin, Dmitry]

The logic of the original commit 4d99b2581eff ("staging: lustre: avoid 
intensive reconnecting for ko2iblnd")
was assumed conditional free of struct kib_conn if the second argument 
free_conn in function
kiblnd_destroy_conn(struct kib_conn *conn, bool free_conn) is true. But this 
hunk of code was dropped
from original commit. As result the logic works wrong and current code use 
struct kib_conn after
free.

[PATCH v2] staging: fsl-mc: Convert documentation to rst format

[Ioana Radulescu]

Update the doc file to comply with the rst format.

It's not integrated into the documentation build structure yet,
since it's still located in drivers/staging.

 A DPAA2 hardware component called the Management Complex (or MC) manages the
 DPAA2 hardware resources.  The MC provides an object-based abstraction for
 software drivers to use the DPAA2 hardware.
-
 The MC uses DPAA2 hardware resources such as queues, buffer pools, and
 network ports to create functional objects/devices such as network
 interfaces, an L2 switch, or accelerator instances.

 The MC provides memory-mapped I/O command interfaces (MC portals)

I've not fixed these as I didn't want to hazard a guess.

Sure, I can do this.

Even with -M, the diff is rather large since the indenting changes for most
of the lines in the file. Would it be better to make two patches, with
the first changing just line indenting and the second one, where the file is
moved, only updating rst specific markups?

This looks all good to me. I think we should have this included in linux-next as
soon as possible, but this probably means after -rc1 at the current point, since
it's a bit late for 4.16.

I'll pick up the series into my randconfig build tree again to find
possible build
time regressions. Otherwise the way I'd stage it out is to put it into my y2038
branch after -rc1 and then send a pull request to Thomas for the tip tree
a week later. It seems unlikely that any major problems come up, so we could
plan to address additional requests for changes by adding commits on top
once it's in linux-next.

Please generate patches with the -M option to git format-patch, so we
can see the file move, not just get removed and added as a brand new

Hm, I don't think you want to do that.  How can a Linux driver subsytem
that wraps calls to the kernel's driver core (which are GPL-only), be
accessed by BSD-3 code?

If I didn't know any better, I would think you were trying to create a
"GPL Condom" here :)

Anyway, why all of the BSD-3 stuff here?  That makes no sense for kernel
code at all, and this is a relicensing of the file, have you gotten
legal approval of everyone that has modified the file while it was under
the GPL-v2 only text to be able to change it to BSD-3 as well?

Careful, this is a _VERY_ tricky thing to do right.  I need a
signed-off-by on this type of patch from your legal council to ensure
that they know exactly what you are doing, and have reviewed it
properly, before I can take it.

Hint, stick to the existing license in the files, it makes more sense,
you are not going to be taking this code out of Linux and putting it
anywhere.

thanks,

greg k-h

[PATCH 0/8] staging: fsl-mc: Cleanup

[Bogdan Purcareata]

The patchset aims to address most of the feedback gathered at the latest
attempt to move it out of staging. You can find the discussion here [1].

Patches 1-2 remove unused code and consolidate the fsl-mc core bus
infrastructure header files into fsl-mc-private.h.

Patch 3 removes full license text and adds SPDX tags to files under
staging/fsl-mc.

Patches 4-6 cleanup the fsl-mc msi/irq code, updating the initialization
routine and removing code that's no longer needed.

Patches 7-8 cleanup the fsl-mc bus documentation and convert it to be
compatible with the kernel documentation build process (.rst).

[PATCH 8/8] staging: fsl-mc: Convert documentation to rst format

[Bogdan Purcareata]

From: Ioana Radulescu 

Update the doc file to comply with the rst format.

It's not integrated into the documentation build structure yet,
since it's still located in drivers/staging.

-Introduction
-
-
-DPAA2 is a hardware architecture designed for high-speeed network
-packet processing.  DPAA2 consists of sophisticated mechanisms for
-processing Ethernet packets, queue management, buffer management,
-autonomous L2 switching, virtual Ethernet bridging, and accelerator
-(e.g. crypto) sharing.
-
-A DPAA2 hardware component called the Management Complex (or MC) manages the
-DPAA2 hardware resources.  The MC provides an object-based abstraction for
-software drivers to use the DPAA2 hardware.
-
-The MC uses DPAA2 hardware resources such as queues, buffer pools, and
-network ports to create functional objects/devices such as network
-interfaces, an L2 switch, or accelerator instances.
-
-The MC provides memory-mapped I/O command interfaces (MC portals)
-which DPAA2 software drivers use to operate on DPAA2 objects.
-
-The diagram below shows an overview of the DPAA2 resource management
-architecture:

[PATCH 6/8] staging: fsl-mc: Update include header

[Bogdan Purcareata]

From: Ioana Radulescu 

With the declarations of its_fsl_mc_msi_init/cleanup() now removed
from fsl-mc-private.h, irq-gic-v3-its-fsl-mc-msi.c only needs a
couple of definitions from mc.h, so include that header directly.

[PATCH 5/8] staging: fsl-mc: Remove unnecessary dependency

[Bogdan Purcareata]

From: Ioana Radulescu 

The function that enables fsl-mc msi interrupts doesn't need
to be explicitly called from the fsl-mc bus driver initialization
routine.

Mark it to be independently called at system init; this is in line
with how things are handled by other GICv3 irqchip users.

Due to this change we now have an unused cleanup function, so
remove it.

[PATCH] scsi: storvsc: missing error code in storvsc_probe()

[Dan Carpenter]

We should set the error code if fc_remote_port_add() fails.

[PATCH] staging: lustre: lnet: avoid uninitialized return value

[Arnd Bergmann]

gcc warns that the latest workqueue change leads to returning an
uninitialized variable:

drivers/staging/lustre/lnet/selftest/module.c: In function 'lnet_selftest_init':
drivers/staging/lustre/lnet/selftest/module.c:98:10: error: 'rc' may be used 
uninitialized in this function [-Werror=maybe-uninitialized]

A failure from alloc_ordered_workqueue() tends to indicate an
out-of-memory condition, so return -ENOMEM in both cases.
The second error path was a preexisting bug, where we always
returned zero after a kvmalloc_array() failure.

Fixes: 6106c0f82481 ("staging: lustre: lnet: convert selftest to use 
workqueues")

This check is not there in the kernel.org kernel.  In the upstream
kernel it frees it unconditionally.  The "free_conn" parameter was added
in commit 4d99b2581eff ("staging: lustre: avoid intensive reconnecting
for ko2iblnd") but that line must have been left out.
