If a command is aborted in the kernel but not in the adapter, it might be
considered complete and its DMA memory released, but it is still alive in
the adapter, which will trigger an invalid DMA access upon its completion
(in the DMA operations to deliver the command response to the driver).
On powerpc platforms with IOMMU/EEH capabilities, the problem is observed
during PCI device removal with ongoing IO requests -- which might trigger
an EEH event very often, pointing to a 'TCE Request Page Access Error'.
In that path, which is qla2x00_remove_one(), the commands are aborted in
qla2x00_abort_all_cmds(), which does not perform an abort in the adapter
as is done in qla2xxx_eh_abort() for example.
So, this patch changes qla2x00_abort_all_cmds() to abort commands in the
adapter too, with a call to qla2xxx_eh_abort(), which already implements
all the logic to submit abort requests and handle responses.

When the driver is unloading, in qla2x00_remove_one(), there is a single
call/point in time to abort ongoing commands, qla2x00_abort_all_cmds(),
which is still several steps away from the call to scsi_remove_host().
If more commands continue to arrive and be processed during that
interval, when the driver is tearing down and releasing its structures,
it might potentially hit an oops due to invalid memory access:
Unable to handle kernel paging request for data at address 0x00000138
<...>
NIP [d000000004700a40] qla2xxx_queuecommand+0x80/0x3f0 [qla2xxx]
LR [d000000004700a10] qla2xxx_queuecommand+0x50/0x3f0 [qla2xxx]
So, fail commands in qla2xxx_queuecommand() if the UNLOADING bit is set.

If we're using a shadow copy of a PCI device ROM, the shadow copy is in RAM
and the device never sees accesses to it and doesn't respond to it. We
don't have to route the shadow range to the PCI device, and the device
doesn't have to claim the range.
Previously we treated the shadow copy as though it were the ROM BAR, and we
failed to claim it because the region wasn't routed to the device:
pci 0000:01:00.0: Video device with shadowed ROM at [mem 0x000c0000-0x000dffff]
pci_bus 0000:01: Allocating resources
pci 0000:01:00.0: can't claim BAR 6 [mem 0x000c0000-0x000dffff]: no compatible bridge window
The failure path of pcibios_allocate_dev_rom_resource() cleared out the
resource start address, which also caused the following ioremap() warning:
WARNING: CPU: 0 PID: 116 at /build/linux-akdJXO/linux-4.8.0/arch/x86/mm/ioremap.c:121 __ioremap_caller+0x1ec/0x370
ioremap on RAM at 0x0000000000000000 - 0x000000000001ffff
Handle an option ROM shadow copy as RAM, without trying to insert it into
the iomem resource tree.
This fixes a regression caused by 0c0e0736acad ("PCI: Set ROM shadow
location in arch code, not in PCI core"), which appeared in v4.6. The
regression causes video device initialization to fail. This was reported
on AMD Turks, but it likely affects others as well.

Returning -EINVAL from a bool-returning function
phm_check_smc_update_required_for_display_configuration has an unexpected
effect of returning true, which is probably not what was intended.
Replace -EINVAL by false.
The only place this function is called from is
psm_adjust_power_state_dynamic in
drivers/gpu/drm/amd/powerplay/eventmgr/psm.c:106:
if (!equal || phm_check_smc_update_required_for_display_configuration(hwmgr)) {
phm_apply_state_adjust_rules(hwmgr, requested, pcurrent);
phm_set_power_state(hwmgr, &pcurrent->hardware, &requested->hardware);
hwmgr->current_ps = requested;
}

When we iterate a master's config entries, what we generally care
about is the entry's stream map index, rather than the entry index
itself, so it's nice to have the iterator automatically assign the
former from the latter. Unfortunately, booting with KASAN reveals
the oversight that using a simple comma operator results in the
entry index being dereferenced before being checked for validity,
so we always access one element past the end of the fwspec array.
Flip things around so that the check always happens before the index
may be dereferenced.

We now delay installing our per-bus iommu_ops until we know an SMMU has
successfully probed, as they don't serve much purpose beforehand, and
doing so also avoids fights between multiple IOMMU drivers in a single
kernel. However, the upshot of passing the return value of bus_set_iommu()
back from our probe function is that if there happens to be more than
one SMMUv3 device in a system, the second and subsequent probes will
wind up returning -EBUSY to the driver core and getting torn down again.
Avoid re-setting ops if ours are already installed, so that any genuine
failures stand out.

The 32-bit ARM DMA configuration code predates the IOMMU core's default
domain functionality, and instead relies on allocating its own domains
and attaching any devices using the generic IOMMU binding to them.
Unfortunately, it does this relatively early on in the creation of the
device, before we've seen our add_device callback, which leads us to
attempt to operate on a half-configured master.
To avoid a crash, check for this situation on attach, but refuse to
play, as there's nothing we can do. This at least allows VFIO to keep
working for people who update their 32-bit DTs to the generic binding,
albeit with a few (innocuous) warnings from the DMA layer on boot.

This new function should be used by drivers when setting a implicit
fence for the plane. It abstracts the fact that the user might have
chosen explicit fencing instead.

It is kind of a pointless restriction. If userspace does silly things
like using crtcA's cursor plane on crtcB, and then setcursor on crtcA,
it will end up with the overlay disabled on crtcB. But userspace is
allowed to shoot itself like this.
v2: don't WARN_ON() if caller did not set ->possible_crtcs. This keeps
the existing behavior by default, if caller does not set the
->possible_crtcs.

All the VICs apart from 58 and 59 have the word "Hz" included in the
comment. Include it for 59 and 59 as well.

A frequent issue that arises on shutdown is the drm_mm range manager
complaining of a leak. To aide debugging those, drm can now track the
allocation callsite and print those for the leaks.

We can use the kernel's stack tracer and depot to record the allocation
site of every drm_mm user. Then on shutdown, as well as warning that
allocated nodes still reside with the drm_mm range manager, we can
display who allocated them to aide tracking down the leak.
v2: Move Kconfig around so it lies underneath the DRM options submenu.

Need to ensure that reg_output is not updated while setting multiple
bits. This makes the mutex locking behaviour for the set_multiple call
consistent with that of the set_value call.

gpiod_set_array_value_complex does not clear the bits field.
Therefore when the drivers set_multiple funciton is called bits outside
the mask are undefined and can be either set or not. So bank_val needs
to be masked with bank_mask before or with the reg_val cache.

Virtio 1.0 spec says VIRTIO_F_ANY_LAYOUT and VIRTIO_NET_F_GSO are
legacy-only feature bits. Do not negotiate them in virtio 1 mode. Note
this is a spec violation so we need to backport it to stable/downstream
kernels.
