This change introduces an 'external mode' for GPIO-based FSI masters,
allowing the clock and data lines to be driven by an external source.
For example, external mode is selected by a user when an external debug
device is attached to the FSI pins.
To do this, we need to set specific states for the trans, mux and enable
GPIOs, and prevent access to clk & data from the FSI core code (by
returning EBUSY).
External mode is controlled by a sysfs attribute, so add the relevant
information to Documentation/ABI/

Currently, we perform GPIO accesses in fsi_master_gpio_break and

We'll want non-core fsi code to trigger a rescan, so introduce a

ctxid_pid and vmid_val in config are of type u64. When an integer
0xFF is being left shifted more than 32 bits, the behavior is
undefined. The fix is to specify 0xFF as an unsigned long.

Commit ad67b74d2469 ("printk: hash addresses printed with %p") lets
printk specifier %p to hash all addresses before printing, this was
resulting in the high 32 bits of pcsr can only output zeros. So
module cannot completely print pc value and it's pointless for debugging
purpose.
This patch fixes this by using %px to print pcsr instead.

There is no need to repeat the work that is already done in the PCI
driver core. The patch removes excerpts from suspend and resume
callbacks.
Note that there is no more calls performed to enable or disable a PCI
device during suspend-resume cycle. Nowadays they seems to be
superflous. Someone can read more in [1].
While here, convert calls to new driver API.

Our num_pages_onlined accounting is buggy:
1) In case we're offlining a memory block which was present at boot (e.g.
when there was no hotplug at all) we subtract 32k from 0 and as
num_pages_onlined is unsigned get a very big positive number.
2) Commit 6df8d9aaf3af ("Drivers: hv: balloon: Correctly update onlined
page count") made num_pages_onlined counter accurate on onlining but
totally incorrect on offlining for partly populated regions: no matter
how many pages were onlined and what was actually added to
num_pages_onlined counter we always subtract the full region (32k) so
again, num_pages_onlined can wrap around zero. By onlining/offlining
the same partly populated region multiple times we can make the
situation worse.
Solve these issues by doing accurate accounting on offlining: walk HAS
list, check for covered range and gaps.

The 2016 version of Hyper-V offers the option to operate the guest VM
per-vcpu stimer's in Direct Mode, which means the timer interupts on its
own vector rather than queueing a VMbus message. Direct Mode reduces
timer processing overhead in both the hypervisor and the guest, and
avoids having timer interrupts pollute the VMbus interrupt stream for
the synthetic NIC and storage. This patch enables Direct Mode by
default on stimer0 when running on a version of Hyper-V that supports
it.
In prep for coming support of Hyper-V on ARM64, the arch independent
portion of the code contains calls to routines that will be populated
on ARM64 but are not needed and do nothing on x86.

On Hyper-V the VF NIC has the same MAC as the related synthetic NIC.
VF NIC can work under the synthetic NIC transparently, without its
own IP address. The existing KVP daemon only gets IP from the first
NIC matching a MAC address, and may not be able to find the IP in
this case.
This patch fixes the problem by searching the NIC matching the MAC,
and having an IP address. So, the IP address will be found and
reported to the host successfully.

The cond_resched() currently in the setup path needs to be duplicated in
the teardown path. Rather than require each instance of
for_each_device_pfn() to open code the same sequence, embed it in the
helper.

Re-enable deep flush so that users always have a way to be sure that a
write makes it all the way out to media. Writes from the PMEM driver
always arrive at the NVDIMM since movnt is used to bypass the cache, and
the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to
flush write buffers on power failure. The Deep Flush mechanism is there
to explicitly write buffers to protect against (rare) ADR failure. This
change prevents a regression in deep flush behavior so that applications
can continue to depend on fsync() as a mechanism to trigger deep flush
in the filesystem-DAX case.
