Currently a scsi device won't contribute to kernel randomness when it uses
blk-mq. Since we commonly use scsi on rotational device with blk-mq, it make
sense to keep contributing to kernel randomness in these cases. This is
especially important for virtual machines.
commit b5b6e8c8d3 ("scsi: virtio_scsi: fix IO hang caused by automatic irq
vector affinity") made all virtio-scsi device to use blk-mq, which does not
contribute to randomness today. So for a virtual machine only having
virtio-scsi disk (which is common), it will simple stop getting randomness
from its disks in today's implementation.
With this patch, if the above VM has rotational virtio-scsi device, then it
can still benefit from the entropy generated from the disk.

Currently the UDPv6 early demux rx code path lacks some mandatory
checks, already implemented into the normal RX code path - namely
the checksum conversion and no_check6_rx check.
Similar to the previous commit, we move the common processing to
an UDPv6 specific helper and call it from both edemux code path
and normal code path. In respect to the UDPv4, we need to add an
explicit check for non zero csum according to no_check6_rx value.

'ext4_da_aops' is set to address_space_operations of existing DAX

ext4_set_aops() in the open path.

Ext4 mount path calls .bmap to the journal inode. This currently

In preparation to fix ext4_iget() to set 'ext4_dax_aops' for ext4
DAX files, add ext4_bmap() to 'ext4_dax_aops', since bmap works for

Another reason is we will also have random I/O error on

The recent removal of the memblock dependency from kvmclock caused a SEV
guest regression because the wall_clock and hv_clock_boot variables are
no longer mapped decrypted when SEV is active.
Use the __bss_decrypted attribute to put the static wall_clock and
hv_clock_boot in the .bss..decrypted section so that they are mapped
decrypted during boot.
In the preparatory stage of CPU hotplug, the per-cpu pvclock data pointer
assigns either an element of the static array or dynamically allocated
memory for the pvclock data pointer. The static array are now mapped
decrypted but the dynamically allocated memory is not mapped decrypted.
However, when SEV is active this memory range must be mapped decrypted.
Add a function which is called after the page allocator is up, and
allocate memory for the pvclock data pointers for the all possible cpus.
Map this memory range as decrypted when SEV is active.

kvmclock defines few static variables which are shared with the
hypervisor during the kvmclock initialization.
When SEV is active, memory is encrypted with a guest-specific key, and
if the guest OS wants to share the memory region with the hypervisor
then it must clear the C-bit before sharing it.
Currently, we use kernel_physical_mapping_init() to split large pages
before clearing the C-bit on shared pages. But it fails when called from
the kvmclock initialization (mainly because the memblock allocator is
not ready that early during boot).
Add a __bss_decrypted section attribute which can be used when defining
such shared variable. The so-defined variables will be placed in the
.bss..decrypted section. This section will be mapped with C=0 early
during boot.
The .bss..decrypted section has a big chunk of memory that may be unused
when memory encryption is not active, free it when memory encryption is
not active.

A recent version of the datasheet lists temperature source 11 as reserved.
However, an older version of the datasheet lists temperature sources 10
and 11 as supported virtual temperature sources. Apparently the older
version of the datasheet is correct, so list those temperature sources
as supported.
Virtual temperature sources are different than other temperature sources:
Values are not read from a temperature sensor, but written either from
BIOS or an embedded controller. As such, each virtual temperature has to
be reported. Since there is now more than one temperature source, we have
to keep virtual temperature sources in a chip-specific mask and can no
longer rely on the assumption that there is only one virtual temperature
source with a fixed index. This accounts for most of the complexity of this
patch.

Add a helper for the case when the nfs4 open state has been set to use
a delegation stateid, and we want to revert to using the open stateid.
Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
The previous fix broke recovery of delegated stateids because it assumes
that if we did not mark the delegation as suspect, then the delegation has
effectively been revoked, and so it removes that delegation irrespectively
of whether or not it is valid and still in use. While this is "mostly
harmless" for ordinary I/O, we've seen pNFS fail with LAYOUTGET spinning
in an infinite loop while complaining that we're using an invalid stateid
(in this case the all-zero stateid).
What we rather want to do here is ensure that the delegation is always
correctly marked as needing testing when that is the case. So we want
to close the loophole offered by nfs4_schedule_stateid_recovery(),
which marks the state as needing to be reclaimed, but not the
delegation that may be backing it.
