In case the reset sequence fails (ena_destroy_device() followed by
ena_restore_device() calls) during ena_restore_device(), the driver
resources are being freed. After the clean-up, the timer service is
re-armed in order to try and re-initialize the driver state.
But, such an attempt would fail given that the resources are freed.
Moreover, this would actually cause either the system to fail or a
panic.
When the driver fails in ena_restore_device() procedure, the only
recovery is either unloading and loading the driver or instance
reboot.
This change removes the timer service re-arm in case of failure
in ena_restore_device().

Commit [1] first added the ena_tx_buffer.print_once member,
so that a message about a missing tx completion is printed only
once per packet (and not every second when the watchdog runs).
In this commit print_once is initialized to true, and is set back
to false after detecting a missing tx completion and printing
a warning about it to dmesg.
Commit [2] incorrectly reverses the values assigned to print_once.
The variable is initialized to be true but is checked to be false
when a missing tx completion is detected. This is never true, and
therefore the warning print for each missing tx completion is never
printed since this commit.
Commit [3] added time passed since last TX cleanup to the missing
tx completions per-packet print. However, due to the issue in commit
[2], this time is never printed.
This commit reverses back the values assigned to ena_tx_buffer.print_once
erroneously by commit [2], bringing back to life the missing tx
completion per-packet print.
Also add a space after "." in the missing tx completion print.

To attach to the hypervisor, kvmclock needs to write a per-CPU MSR.
When EARLY_AP_STARTUP is not defined, device attach happens too early:
APs are not yet spun up, so smp_rendezvous only runs the callback on the
local CPU. As a result, the timecounter only gets initialized on the
BSP, and then timekeeping is broken on SMP systems.
Implement handling for !EARLY_AP_STARTUP kernels: keep track of the CPU
on which device attach ran, and then use a SI_SUB_SMP SYSINIT to
register the rest of the CPUs with the hypervisor.

Virtio operates with physical addresses, while busdma is designed to
map these to produce bus addresses. On most supported platforms,
these two are interchangeable; on powerpc platforms, they are not.
When on powerpc, set an IOMMU of NULL, which causes the powerpc busdma
code to bypass the iommu mapping; this leaves us with the physical
buffer addresses which the virtio host expects to see.

Simply said, WDAT is an abstraction for the real WDT hardware. For
instance, to add a newer generation WDT to ichwd(4), one must know the
detailed hardware registers, etc..
With WDAT, the necessary IO accesses to operate the WDT are comprehensively
described in it and no hardware knowledge is required.
With this driver, the WDT on Advantech ARK-1124C, Dell R210 and Dell R240 are
detected and operated flawlessly.
* While R210 is also supported by ichwd(4), others are not supported yet.
The unfortunate thing is that not all systems have WDAT defined.

Prior to Conrad's changes to replace session integer IDs with a
pointer to the driver-specific state in commit 1b0909d51a, the
driver had to find the softc pointer from the adapter before it could
locate the ccr_session structure for a completed request. Since
Conrad's changes, the ccr_session pointer can now be obtained directly
from the crp. Add a backpoint from ccr_session back to ccr_softc and
use this in place of the ccr_softc member in cxgbe's struct adapter.
