Legacy PCI over virtio uses a 32bit PFN for the queue. If the
queue pfn is too large to fit in 32bits, which we could hit on
arm64 systems with 52bit physical addresses (even with 64K page
size), we simply miss out a proper link to the other side of
the queue.
Add a check to validate the PFN, rather than silently breaking
the devices.

The OOM notifier is getting deprecated to use for the reasons:
- As a callout from the oom context, it is too subtle and easy to
generate bugs and corner cases which are hard to track;
- It is called too late (after the reclaiming has been performed).
Drivers with large amuont of reclaimable memory is expected to
release them at an early stage of memory pressure;
- The notifier callback isn't aware of oom contrains;
Link: https://lkml.org/lkml/2018/7/12/314
This patch replaces the virtio-balloon oom notifier with a shrinker
to release balloon pages on memory pressure. The balloon pages are
given back to mm adaptively by returning the number of pages that the
reclaimer is asking for (i.e. sc->nr_to_scan).
Currently the max possible value of sc->nr_to_scan passed to the balloon
shrinker is SHRINK_BATCH, which is 128. This is smaller than the
limitation that only VIRTIO_BALLOON_ARRAY_PFNS_MAX (256) pages can be
returned via one invocation of leak_balloon. But this patch still
considers the case that SHRINK_BATCH or shrinker->batch could be changed
to a value larger than VIRTIO_BALLOON_ARRAY_PFNS_MAX, which will need to
do multiple invocations of leak_balloon.
Historically, the feature VIRTIO_BALLOON_F_DEFLATE_ON_OOM has been used
to release balloon pages on OOM. We continue to use this feature bit for
the shrinker, so the shrinker is only registered when this feature bit
has been negotiated with host.

Pull core signal handling updates from Eric Biederman:
"It was observed that a periodic timer in combination with a
sufficiently expensive fork could prevent fork from every completing.
This contains the changes to remove the need for that restart.
This set of changes is split into several parts:
- The first part makes PIDTYPE_TGID a proper pid type instead
something only for very special cases. The part starts using
PIDTYPE_TGID enough so that in __send_signal where signals are
actually delivered we know if the signal is being sent to a a group
of processes or just a single process.
- With that prep work out of the way the logic in fork is modified so
that fork logically makes signals received while it is running
appear to be received after the fork completes"

DCN1 contains code that utilizes fp math. When
CONFIG_KCOV_INSTRUMENT_ALL and CONFIG_KCOV_ENABLE_COMPARISONS are
enabled, build errors are found. See this earlier patch for details:
https://lists.freedesktop.org/archives/dri-devel/2018-August/186131.html
As a short term solution, disable CONFIG_DRM_AMD_DC_DCN1_0 when
KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. In
addition, make it a fully derived config, taking into account
CONFIG_X86.

The sysfs attributes /sys/bus/ap/apmask and /sys/bus/ap/aqmask
and the kernel command line arguments ap.apm and ap.aqm get
an improvement of the value parsing with this patch:
The mask values are bitmaps in big endian order starting with bit 0.
So adapter number 0 is the leftmost bit, mask is 0x8000... The sysfs
attributes and the kernel command line accept 2 different formats:
- Absolute hex string starting with 0x like "0x12345678" does set
the mask starting from left to right. If the given string is shorter
than the mask it is padded with 0s on the right. If the string is
longer than the mask an error comes back (EINVAL).
- Relative format - a concatenation (done with ',') of the terms
+<bitnr>[-<bitnr>] or -<bitnr>[-<bitnr>]. <bitnr> may be any
valid number (hex, decimal or octal) in the range 0...255.
Here are some examples:
"+0-15,+32,-128,-0xFF"
"-0-255,+1-16,+0x128"

When thermal zone is in passive mode, disabling its mode from
sysfs is NOT taking effect at all, it is still polling the
temperature of the disabled thermal zone and handling all thermal
trips, it makes user confused. The disabling operation should
disable the thermal zone behavior completely, for both active and
passive mode, this patch clears the passive_delay when thermal
zone is disabled and restores it when it is enabled.

This is unnecessary and triggers a warning in the hypervisor.
Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.

Keep sending mailbox commands to the MFW when it is not responsive ends up
with a redundant amount of timeout expiries.
This patch prints the MCP status on the first command which is not
responded, and blocks the following commands.
Since the (un)load request commands might be not responded due to other
PFs, the patch also adds the option to skip the blocking upon a failure.

The MFW manages an internal lock to prevent concurrent hardware
(de)initialization of different PFs.
This, together with the busy-waiting for the MFW's responses for commands,
might lead to a deadlock during concurrent load or unload of PFs.
This patch adds the option to sleep within the busy-waiting, and uses it
for the (un)load requests (which are not sent from an interrupt context) to
prevent the possible deadlock.

Successive iterations of halting and resuming the management chip (MCP)
might fail, since currently the driver doesn't wait for these operations to
actually take place.
This patch prevents the driver from moving forward before the operations
are reflected in the state register.

The MFW might be reset and re-update its shared memory.
Upon the detection of such a reset the driver rereads this memory, but it
has to wait till the data is valid.
This patch adds the missing wait for a data ready indication.
