Discard can return -EIO asynchronously if the alignment for the request
isn't suitable for the driver, which makes a proper fallback to other
methods in __blkdev_issue_zeroout impossible. Thus only issue a sync
discard from blkdev_issue_zeroout an don't try discard at all from
__blkdev_issue_zeroout as a non-invasive workaround.
One more reason why abusing discard for zeroing must die..

If the server reboots multiple times, the client should rely on the
server to tell it that it cannot reclaim state as per section 9.6.3.4
in RFC7530 and section 8.4.2.1 in RFC5661.
Currently, the client is being to conservative, and is assuming that
if the server reboots while state recovery is in progress, then it must
ignore state that was not recovered before the reboot.

platform device"
Commit 72a9b186292d ("xen: Remove event channel notification through Xen
PCI platform device") broke Linux when booting as Dom0 on Xen in a
nested Xen environment (Xen installed inside a Xen VM). In this
scenario, Linux is a PV guest, but at the same time it uses the
platform-pci driver to receive notifications from L0 Xen. vector
callbacks are not available because L1 Xen doesn't allow them.
Partially revert the offending commit, by restoring IRQ based
notifications for PV guests only. I restored only the code which is
strictly needed and replaced the xen_have_vector_callback checks within
it with xen_pv_domain() checks.

AHCI provides the register PORTS_IMPL to let the software know which port
is supported. The register must be initialized by the bootloader. However
in some cases u-boot doesn't properly initialize this value (if it is not
compiled with SATA support for example or if the SATA initialization fails).
The DTS entry "ports-implemented" can be used to override the value in
PORTS_IMPL.
Without this patch the SATA will not work in the following two cases:
* if there has been a failure to initialize SATA in u-boot.
* if ahci_platform module has been removed and re-inserted. The reason is
that the content of PORTS_IMPL is lost after the module is removed.
I suspect that it's because the controller is reset by the hwmod.

Due to the way kbuild works, this header was unintentionally exported
back in 2013 when it was created, despite it not being in a uapi/

However, we've had this include exported to userland for almost four
years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
no hint that anyone has complained about it. So, let's make it
officially exported in this state.

Station structure is considered as not uploaded
(to driver) until drv_sta_state() finishes. This
call is however done after the structure is
attached to mac80211 internal lists and hashes.
This means mac80211 can lookup (and use) station
structure before it is uploaded to a driver.
If this happens (structure exists, but
sta->uploaded is false) fast_tx path can still be
taken. Deep in the fastpath call the sta->uploaded
is checked against to derive "pubsta" argument for
ieee80211_get_txq(). If sta->uploaded is false
(and sta is actually non-NULL) ieee80211_get_txq()
effectively downgraded to vif->txq.
At first glance this may look innocent but coerces
mac80211 into a state that is almost guaranteed
(codel may drop offending skb) to crash because a
station-oriented skb gets queued up on
vif-oriented txq. The ieee80211_tx_dequeue() ends
up looking at info->control.flags and tries to use
txq->sta which in the fail case is NULL.
It's probably pointless to pretend one can
downgrade skb from sta-txq to vif-txq.
Since downgrading unicast traffic to vif->txq must
not be done there's no txq to put a frame on if
sta->uploaded is false. Therefore the code is made
to fall back to regular tx() op path if the
described condition is hit.
Only drivers using wake_tx_queue were affected.

Current KVM world switch code is unintentionally setting wrong bits to
CNTHCTL_EL2 when E2H == 1, which may allow guest OS to access physical
timer. Bit positions of CNTHCTL_EL2 are changing depending on
HCR_EL2.E2H bit. EL1PCEN and EL1PCTEN are 1st and 0th bits when E2H is
not set, but they are 11th and 10th bits respectively when E2H is set.
In fact, on VHE we only need to set those bits once, not for every world
switch. This is because the host kernel runs in EL2 with HCR_EL2.TGE ==
1, which makes those bits have no effect for the host kernel execution.
So we just set those bits once for guests, and that's it.

When a VCPU blocks (WFI) and has programmed the vtimer, we program a
soft timer to expire in the future to wake up the vcpu thread when
appropriate. Because such as wake up involves a vcpu kick, and the
timer expire function can get called from interrupt context, and the
kick may sleep, we have to schedule the kick in the work function.
The work function currently has a warning that gets raised if it turns
out that the timer shouldn't fire when it's run, which was added because
the idea was that in that case the work should never have been cancelled.
However, it turns out that this whole thing is racy and we can get
spurious warnings. The problem is that we clear the armed flag in the
work function, which may run in parallel with the
kvm_timer_unschedule->timer_disarm() call. This results in a possible
situation where the timer_disarm() call does not call
cancel_work_sync(), which effectively synchronizes the completion of the
work function with running the VCPU. As a result, the VCPU thread
proceeds before the work function completees, causing changes to the
timer state such that kvm_timer_should_fire(vcpu) returns false in the
work function.
All we do in the work function is to kick the VCPU, and an occasional
rare extra kick never harmed anyone. Since the race above is extremely
rare, we don't bother checking if the race happens but simply remove the
check and the clearing of the armed flag from the work function.

capability of current task; in the course of mdev development a
new requirement, testing for another task other than current, was
raised. ns_capable() was used for this purpose, however it still
tests current, the only difference is, in a specified namespace.
Fix it by using has_capability() instead, which tests the cap for

While probing BGX we requesting appropriate QLM for it's configuration
and get LMAC count by that request. Then, while reading configured
MAC values from SSDT table we need to save them in proper mapping:
BGX[i]->lmac[j].mac = <MAC value>
to later provide for initialization stuff. In order to fill
such mapping properly we need to add lmac index to be used while
acpi initialization since at this moment bgx->lmac_count already contains
actual value.

In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path
invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes
svc_rdma_put_frmr() which in turn tries to unmap the same sg list through
ib_dma_unmap_sg() again. This second unmap is invalid and could lead to
problems when the iova being unmapped is subsequently reused. Remove
the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr()
handle it.

After the addition of the frame_retries callback we could run into cases where
a ATUSB device with an older firmware version would now longer be able to bring
the interface up.
We keep this functionality disabled now if the minimum firmware version for this
feature is not available.

Driver code never touches "rstn" signal in atomic context, so there's
no need to implicitly put such restriction on it by using gpio_set_value
to manipulate it. Replace gpio_set_value to gpio_set_value_cansleep to
fix that.
As a an example of where such restriction might be inconvenient,
consider a hardware design where "rstn" is connected to a pin of I2C/SPI
GPIO expander chip.

From 4.9 we should really avoid using the stack here as this will not be DMA
able on various platforms. This changes a buffer that was introduced in the

The inet6addr_chain is an atomic notifier chain, so we can't call
anything that might sleep (like lock_sock)... instead of closing the
socket from svc_age_temp_xprts_now (which is called by the notifier
function), just have the rpc service threads do it instead.

Context expiry times are in units of seconds since boot, not unix time.
The use of get_seconds() here therefore sets the expiry time decades in
the future. This prevents timely freeing of contexts destroyed by
client RPC_GSS_PROC_DESTROY requests. We'd still free them eventually
(when the module is unloaded or the container shut down), but a lot of
contexts could pile up before then.

Oops--in 916d2d844afd I moved some constants into an array for
convenience, but here I'm accidentally writing to that array.
The effect is that if you ever encounter a filesystem lacking support
for ACLs or security labels, then all queries of supported attributes
will report that attribute as unsupported from then on.
