ice_vsi_type_str converts an ice_vsi_type enum value to its string
equivalent. This is expected to help easily identify VSI types from
module print statements.

Currently the VLAN ice_flg64_bits are off by 1. Fix this by
setting the ICE_FLG_EVLAN_x8100 flag to 14, which also updates
ICE_FLG_EVLAN_x9100 to 15 and ICE_FLG_VLAN_x8100 to 16.

Shorten the delay for SQ responses, but increase the number of loops.
Max delay time is unchanged, but some operations complete much more
quickly.
In the process, add a new define to make the delay count and delay time
more explicit. Add comments to make things more explicit.
This fixes a problem with VF resets failing on with many VFs.

Currently we check to make sure the vector_id passed down from iavf
is less than or equal to pf->hw.func_caps.common_caps.num_msix_vectors.
This is incorrect because the vector_id is always 0-based and never
greater than or equal to the ICE_MAX_INTR_PER_VF. Fix this by checking
to make sure the vector_id is less than the max allowed interrupts per
VF (ICE_MAX_INTR_PER_VF).

This patch adds code to check if PF or VF is disabled before honoring
mailbox message to configure VF - If it is disabled, and opcode is for
resetting VF, the PF driver simply tell VF that all is set. In addition,
if reset is ongoing, and Admin intend to configure VF on the host, we can
poll the VF enabling bit to make sure it is ready before continue - If
after ~250 milliseconds, VF is not in active state, we can bail out with
invalid error.

Move software LLDP configuration when FW DCBX is disabled to
ice_init_pf_dcb, since that is where the FW DCBX state is determined.
Remove this software LLDP configuration from ice_vsi_setup and

This patch fixes the call trace caused by the kernel when the Rx/Tx
descriptor size change request is initiated via ethtool when DCB is
configured. ice_set_ringparam() should use vsi->num_txq instead of
vsi->alloc_txq as it represents the queues that are enabled in the
driver when DCB is enabled/disabled. Otherwise, queue index being
used can go out of range.
For example, when vsi->alloc_txq has 104 queues and with 3 TCS enabled
via DCB, each TC gets 34 queues, vsi->num_txq will be 102 and only 102
queues will be enabled.

The Zynq QSPI controller features 2 CS. When the num-cs DT property
is set to 2, the hardware will be initialized to support having two
devices connected over each CS.
In this case, both CS lines are driven by the state of the U_PAGE
(upper page) bit. When unset, the lower page (CS0) is selected,
otherwise it is the upper page (CS1).
Change tested on a custom design featuring two SPI-NORs with different
CS on the Zynq-7000 QSPI bus.

Supporting more than one CS will need some tweaking of the linear
configuration register which is (rightfully) initialized in the
hardware initialization helper. The extra initialization needs the
knowledge of the actual number of CS, which is retrieved by reading
the value of the num-cs DT property.
As the initialization helper is called pretty early and might be
called much later in the probe without side effect, let's delay it a
bit so that the number of CS will be available when running this
helper. This way, adding support for multiple CS lines in a next patch
will be eased.

The code used to assert and de-assert a chip select line is very
complicated for no reason. Simplify the logic by either setting or
resetting the concerned bit, which actually only changes an electrical
state.
Update the comment to reflect that there is no possibility to actually
choose a CS as the default (CS0) will be driven in any case.

Pull arm64 fix from Will Deacon:
"Fix pte_same() to avoid getting stuck on write fault.
This single arm64 fix is a revert of 747a70e60b ("arm64: Fix
copy-on-write referencing in HugeTLB"), not because that patch was
wrong, but because it was broken by aa57157be6 ("arm64: Ensure
VM_WRITE|VM_SHARED ptes are clean by default") which we merged in
-rc6.
We spotted the issue in Android (AOSP), where one of the JIT threads
gets stuck on a write fault during boot because the faulting pte is
marked as PTE_DIRTY | PTE_WRITE | PTE_RDONLY and the fault handler
decides that there's nothing to do thanks to pte_same() masking out
PTE_RDONLY.
Thanks to John Stultz for reporting this and testing this so quickly,
and to Steve Capper for confirming that the HugeTLB tests continue to
pass"

Now that we print diagnostics at boot the reason why we do not initialise
KASLR matters. Currently we check for a seed before we check if the user
has explicitly disabled KASLR on the command line which will result in
misleading diagnostics so reverse the order of those checks. We still
parse the seed from the DT early so that if the user has both provided a
seed and disabled KASLR on the command line we still mask the seed on
the command line.

Currently the KASLR code is silent at boot unless it forces on KPTI in
which case a message will be printed for that. This can lead to users
incorrectly believing their system has the feature enabled when it in
fact does not, and if they notice the problem the lack of any
diagnostics makes it harder to understand the problem. Add an initcall
which prints a message showing the status of KASLR during boot to make
the status clear.
This is particularly useful in cases where we don't have a seed. It
seems to be a relatively common error for system integrators and
administrators to enable KASLR in their configuration but not provide
the seed at runtime, often due to seed provisioning breaking at some
later point after it is initially enabled and verified.
