s390 sets "elfcorehdr_addr = ELFCORE_ADDR_MAX;" early during
setup_arch() to deactivate the "elfcorehdr= kernel" parameter,
resulting in is_kdump_kernel() returning "false".
During vmcore_init()->elfcorehdr_alloc(), if on a dump kernel and
allocation succeeded, elfcorehdr_addr will be set to a valid address
and is_kdump_kernel() will consequently return "true".
is_kdump_kernel() should return a consistent result during all boot
stages, and properly return "true" if in a kdump environment - just
like it is done on powerpc where "false" is indicated in fadump
environments, as added in commit b098f1c323 ("powerpc/fadump: make
is_kdump_kernel() return false when fadump is active").
Similarly provide a custom is_kdump_kernel() implementation that will only
return "true" in kdump environments, and will do so consistently during
boot.
Update the documentation of dump_available().

Starting with commit 2297791c92 ("s390/cio: dont unregister
subchannel from child-drivers"), CIO does not unregister subchannels
when the attached device is invalid or unavailable. Instead, it
allows subchannels to exist without a connected device. However, if
the DNV value is 0, such as, when all the CHPIDs of a subchannel are
configured in standby state, the subchannel is unregistered, which
contradicts the current subchannel specification.
Update the logic so that subchannels are not unregistered based
on the DNV value. Also update the SCHIB information even if the
DNV bit is zero.

At least since commit 334304ac2b ("dma-mapping: don't return errors
from dma_set_max_seg_size") setting up device.dma_parms is basically
mandated by the DMA API. As of now Channel (CCW) I/O in general does not
utilize the DMA API, except for virtio. For virtio-ccw however the
common virtio DMA infrastructure is such that most of the DMA stuff
hinges on the virtio parent device, which is a CCW device.
So lets set up the dma_parms pointer for the CCW parent device and hope
for the best!

Ensure that VFs used in isolation, that is with their parent PF not
visible to the configuration but with their RID exposed, are treated
compatibly with existing isolated VF use cases without exposed RID
including RoCE Express VFs. This allows creating configurations where
one LPAR manages PFs while their child VFs are used by other LPARs. This
gives the LPAR managing the PFs a role analogous to that of the
hypervisor in a typical use case of passing child VFs to guests.
Instead of creating a multifunction struct zpci_bus whenever a PCI
function with RID exposed is discovered only create such a bus for
configured physical functions and only consider multifunction busses
when searching for an existing bus. Additionally only set zdev->devfn to
the devfn part of the RID once the function is added to a multifunction
bus.
This also fixes probing of more than 7 such isolated VFs from the same
physical bus. This is because common PCI code in pci_scan_slot() only
looks for more functions when pdev->multifunction is set which somewhat
counter intutively is not the case for VFs.
Note that PFs are looked at before their child VFs is guaranteed because
we sort the zpci_list by RID ascending.

The newly introduced topology ID (TID) field in the CLP Query PCI
Function explicitly identifies groups of PCI functions whose RIDs belong
to the same (sub-)topology. When available use the TID instead of the
PCHID to match zPCI busses/domains for multi-function devices. Note that
currently only a single PCI bus per TID is supported. This change is
required because in future machines the PCHID will not identify a PCI
card but a specific port in the case of some multi-port NICs while from
a PCI point of view the entire card is a subtopology.

Instead of relying on the observed but not architected firmware behavior
that PCI functions from the same card are listed in ascending RID order
in clp_list_pci() ensure this by sorting. To allow for sorting separate
the initial clp_list_pci() and creation of the virtual PCI busses.
Note that fundamentally in our per-PCI function hotplug design non RID
order of discovery is still possible. For example when the two PFs of
a two port NIC are hotplugged after initial boot and in descending RID
order. In this case the virtual PCI bus would be created by the second
PF using that PF's UID as domain number instead of that of the first PF.
Thus the domain number would then change from the UID of the second PF
to that of the first PF on reboot but there is really nothing we can do
about that since changing domain numbers at runtime seems even worse.
This only impacts the domain number as the RIDs are consistent and thus
even with just the second PF visible it will show up in the correct
position on the virtual bus.

* Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail
* Make sure that the host's vector length is at capped by a value
common to all CPUs
* Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken
* Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly
x86:
* Fix compilation with KVM_INTEL=KVM_AMD=n
* Fix disabling KVM_X86_QUIRK_SLOT_ZAP_ALL when shadow MMU is in use
Selftests:
* Fix compilation on non-x86 architectures

powerpc/vdso: allow r30 in vDSO code generation of getrandom
The blank line causes execve() to fail:
# strace ./postinst
execve("./postinst", ...) = -1 ENOEXEC (Exec format error)
strace: exec: Exec format error
+++ exited with 1 +++
However running the scripts via shell does work (at least with bash)
because the shell attempts to execute the file as a shell script when
execve() fails.

If we follow "make help" to "make dt_binding_schema", we will see
below error:
$ make dt_binding_schema
make[1]: *** No rule to make target 'dt_binding_schema'. Stop.
make: *** [Makefile:224: __sub-make] Error 2
It should be a typo. So this will fix it.

x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().
When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.
