Link resume failure in itself isn't an error condition and may happen
regularly depending on hardware configuration. Reporting it as
KERN_ERR makes the condition unnecessarily prominent (e.g. reported
during boot). Use KERN_WARNING instead.

libata EH intentionally left a port frozen if it failed
ata_eh_reset(). The intention was avoiding continuous loop of resets
when the controller or attached device is flaky and reporting spurious
hotplug events. Once port enters this state, it can be recovered with
manual rescan, which seemed reasonable.
However, outside of my convoluted test setup, there have been very few
reports justifying this choice while there have been more cases where
the automatic freezing of the port after hotplug attempt of a faulty
device caused confusion and led to unnecessary resets.
This patch changes the behavior so that the port is thawed after reset
failure. This change doesn't necessarily solve but makes it easier
and more intuitive to work around hotplug related problems
(ie. re-pluggin or power cycling the device) as reported in the
followings.

Saves text by removing nearly duplicated text format strings by
creating ata_<foo>_printk functions and printf extension %pV.
ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)
Format string duplication comes from:
#define ata_link_printk(link, lv, fmt, args...) do { \

printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id, \

There are many places in the tree where we implement register access for
devices on non-memory mapped buses, especially I2C and SPI. Since hardware
designers seem to have settled on a relatively consistent set of register
interfaces this can be effectively factored out into shared code. There
are a standard set of formats for marshalling data for exchange with the
device, with the actual I/O mechanisms generally being simple byte
streams.
We create an abstraction for marshaling data into formats which can be
sent on the control interfaces, and create a standard method for
plugging in actual transport underneath that.
This is mostly a refactoring and renaming of the bottom level of the
existing code for sharing register I/O which we have in ASoC. A
subsequent patch in this series converts ASoC to use this. The main
difference in interface is that reads return values by writing to a
location provided by a pointer rather than in the return value, ensuring
we can use the full range of the type for register data. We also use
unsigned types rather than ints for the same reason.
As some of the devices can have very large register maps the existing
ASoC code also contains infrastructure for managing register caches.
This cache work will be moved over in a future stage to allow for
separate review, the current patch only deals with the physical I/O.

virtio has been so far used only in the context of virtualization,
and the virtio Kconfig was sourced directly by the relevant arch
Kconfigs when VIRTUALIZATION was selected.
Now that we start using virtio for inter-processor communications,
we need to source the virtio Kconfig outside of the virtualization
scope too.
Moreover, some architectures might use virtio for both virtualization
and inter-processor communications, so directly sourcing virtio
might yield unexpected results due to conflicting selections.
The simple solution offered by this patch is to always source virtio's
Kconfig in drivers/Kconfig, and remove it from the appropriate arch
Kconfigs. Additionally, a virtio menu entry has been added so virtio
drivers don't show up in the general drivers menu.
This way anyone can use virtio, though it's arguably less accessible
(and neat!) for virtualization users now.
Note: some architectures (mips and sh) seem to have a VIRTUALIZATION
menu merely for sourcing virtio's Kconfig, so that menu is removed too.

Change details:
- If there is a command pending in the mailbox, bfa_ioc_mbox_queue() enqueues
the mailbox command to a pending command queue. Entries in this queue are
not flushed when IOC is disabled. As a result, when IOC is re-enabled again,
the stale entries in the pending command queue are posted to the mailbox.
When these mailbox commands are processed by the FW and responses are sent,
unexpected events are received by other modules' FSMs (f.e. bfa_msgq) which
have not posted any mailbox commands after IOC was enabled.
- Flush the pending mailbox command queue when IOC is disabled. Rename
bfa_ioc_mbox_hbfail to bfa_ioc_mbox_flush. Call bfa_ioc_mbox_flush

EFI only provides small amounts of individual storage, and conventionally
puts metadata in the storage variable name. Rather than add a metadata
header to the (already limited) variable storage, it's easier for us to
modify pstore to pass all the information we need to construct a unique
variable name to the appropriate functions.

Some pstore implementations may not have a static context, so extend the
API to pass the pstore_info struct to all calls and allow for a context
pointer.
