fotg210: Make Xen notification consistent with EHCI
If CONFIG_XEN_DOM0 is enabled, the ehci-dbgp driver notifies Xen of
controller reset events via xen_dbgp_reset_prep() and
xen_dbgp_external_startup() (via calls to xen_dbgp_op().) Otherwise
<linux/usb/ehci_def.h> defines them as no-ops to disable this logic.
The fotg210 driver copies much of the dbgp code from ehci_def.h, but it
unconditionally defines the Xen hooks as no-ops, effectively disabling
these notifications when CONFIG_EARLY_PRINTK_DBGP is disabled. When
enabled, though, notifying Xen is dependent on CONFIG_XEN_DOM0 due to
fotg210 leveraging the ehci-dbgp driver.
The following table compares the implementations of xen_dbgp_reset_prep()
and xen_dbgp_external_startup() in the ehci-dbgp and fotg210 drivers
under the relevant configurations:
EARLY_PRINTK_DBGP? XEN_DOM0? ehci-dbgp fotg210
------------------ --------- ------------- -------------
n n no-op no-op
n y xen_dbgp_op() no-op
y n no-op no-op
y y xen_dbgp_op() xen_dbgp_op()
This suggests that fotg210 is, at best, indifferent to whether Xen is
notified of these events. Make fotg210 consistent with ehci-dbgp as a
step towards consolidating this code duplication.

USB: storage: Reject bogus max LUN values
Some mass storage devices return a bogus value in response to a Get Max LUN
request. The Iomega Jaz USB Adapter responds with 0x10, hence my recent
patch to use the US_FL_SINGLE_LUN quirk for it.
The USB MSC Bulk Only Transport document says "The device shall return one
byte of data that contains the maximum LUN supported by the device."
Since the LUN field in the command block wrapper is only 4 bits wide, it
might be helpful to report too-large LUN values in the kernel log, and
assume max LUN is actually 0. That could get some devices which currently
need the US_FL_SINGLE_LUN quirk to work.

uas: Make uas work with blk-mq
With uas over usb-3 the tags inside the uas iu-s must match the usb-3 stream
ids, and those go from 1 - qdepth.
Before blk-mq calling scsi_activate_tcq(sdev, qdepth) guaranteed that we would
only get cmnd->request->tag from 0 - (qdepth - 1), and we used those as
uas-tags / stream-ids.
With blk-mq however we are guaranteed to never get more then qdepth commands
queued at the same time, but the cmnd->request->tag values may be much larger,
which breaks uas.
This commit fixes this by generating uas tags in the 1 - qdepth range ourselves
instead of using cmnd->request->tag.
While touching all involved code anyways also rename the uas_cmd_info stream
field to uas_tag, because when using uas over usb-2 streams are not used.

This patch modifies the usb_authorize_device() function such as that it does
not reload the device descriptor for wired devices. The reasons for this
are as follows:
* Some devices dislike the master requesting the descriptor from them twice,
failing on the usb_get_device_descriptor() call with -ETIMEOUT. Observed this
on my Pretec 16GB flash drive (4146:ba65).
* Malicious device could send two different descriptors - one before

KVM: nVMX: Disable preemption while reading from shadow VMCS
In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.
This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support. Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.

Pull ACPI and power management fixes from Rafael Wysocki:
"These are fixes received after my previous pull request plus one that
has been in the works for quite a while, but its previous version
caused problems to happen, so it's been deferred till now.
Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
ACPI EC regression introduced in 3.17, system suspend error code path
regression introduced in 3.15, an older bug related to recovery from
failing resume from hibernation and a cpufreq-dt driver issue related
to operation performance points.
Specifics:
- Fix a crash on r8a7791/koelsch during resume from system suspend
caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
- Fix an MFD enumeration problem introduced by a recent commit adding
ACPI support to the MFD subsystem that exposed a weakness in the
ACPI core causing ACPI enumeration to be applied to all devices
associated with one ACPI companion object, although it should be
used for one of them only (Mika Westerberg).
- Fix an ACPI EC regression introduced during the 3.17 cycle causing
some Samsung laptops to misbehave as a result of a workaround
targeted at some Acer machines. That includes a revert of a commit
that went too far and a quirk for the Acer machines in question.
From Lv Zheng.
- Fix a regression in the system suspend error code path introduced
during the 3.15 cycle that causes it to fail to take errors from
asychronous execution of "late" suspend callbacks into account
(Imre Deak).
- Fix a long-standing bug in the hibernation resume error code path
that fails to roll back everything correcty on "freeze" callback
errors and leaves some devices in a "suspended" state causing more
breakage to happen subsequently (Imre Deak).
- Make the cpufreq-dt driver disable operation performance points
that are not supported by the VR connected to the CPU voltage plane
with acceptable tolerance instead of constantly failing voltage
scaling later on (Lucas Stach)"

x86_64, entry: Fix out of bounds read on sysenter
Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code
reads out of bounds, causing the NT fix to be unreliable. But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.
Excerpt from the crash:
[ 1.129513] RSP: 0018:
ffff88001da4bf88 EFLAGS:
00010296
2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp)
That read is deterministically above the top of the stack. I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.
