We can easily route hardware interrupts directly into VM context when
they target the "Fixed" or "LowPriority" delivery modes.
However, on modes such as "SMI" or "Init", we need to go via KVM code
to actually put the vCPU into a different mode of operation, so we can
not post the interrupt
Add code in the VMX and SVM PI logic to explicitly refuse to establish
posted mappings for advanced IRQ deliver modes. This reflects the logic
in __apic_accept_irq() which also only ever passes Fixed and LowPriority
interrupts as posted interrupts into the guest.
This fixes a bug I have with code which configures real hardware to
inject virtual SMIs into my guest.

For some applications that end up using a submit-and-wait type of
approach for certain batches of IO, we can make that a bit more
efficient by allowing the application to block for the last IO
submission. This prevents an async when we don't need it, as the
application will be blocking for the completion event(s) anyway.
Typical use cases are using the liburing
io_uring_submit_and_wait() API, or just using io_uring_enter()
doing both submissions and completions. As a specific example,
RocksDB doing MultiGet() is sped up quite a bit with this
change.

2 bytes in MSB of register for clock status is zero during intermediate
state after changing status of sampling clock in models of TASCAM FireWire
series. The duration of this state differs depending on cases. During the
state, it's better to retry reading the register for current status of
the clock.
In current implementation, the intermediate state is checked only when
getting current sampling transmission frequency, then retry reading.
This care is required for the other operations to read the register.
This commit moves the codes of check and retry into helper function
commonly used for operations to read the register.

For sdio chip, if the rssi is not good, then it have some retry,
firmware will indicate the msdu list of a ppdu with a hole, it
means it lost the hole msdu, after the msdu retry from AP, the
hole msdu will indicate from firmware later. The hole msdu's PN
check will fail and the hole msdu will be dropped.
PN check fail example:
Sequence number PN number PN check status
3814 6101 success
3815 6102 success
3816 6103 success
3818 6105 success
3819 6106 success
3820 6107 success
3817 6104 fail
The correct logic is reorder the msdu list and then do PN check.
ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic
and then do PN check in ieee80211_rx_h_decrypt of mac80211.
example after reorder:
Sequence number PN number PN check status
3814 6101 success
3815 6102 success
3816 6103 success
3817 6104 success
3818 6105 success

The recent consolidation of the three permission checks introduced a subtle
regression. For timer_create() with a process wide timer it returns the
current task if the lookup through the PID which is encoded into the
clockid results in returning current.
That's broken because it does not validate whether the current task is the
group leader.
That was caused by the two different variants of permission checks:
- posix_cpu_timer_get() allowed access to the process wide clock when the
looked up task is current. That's not an issue because the process wide
clock is in the shared sighand.
- posix_cpu_timer_create() made sure that the looked up task is the group
leader.
Restore the previous state.
Note, that these permission checks are more than questionable, but that's
subject to follow up changes.

We should only try to execute fallback quirks handling when previous
call returned -ENOENT, and not when we did not get -EPROBE_DEFER.
The other errors should be treated as hard errors: we did find the GPIO
description, but for some reason we failed to handle it properly.
The fallbacks should only be executed when previous handlers returned
-ENOENT, which means the mapping/description was not found.
Also let's remove the explicit deferral handling when iterating through
GPIO suffixes: it is not needed anymore as we will not be calling
fallbacks for anything but -ENOENT.

Commit 3bd7f6589f67 ("spi: bcm2835: Overcome sglist entry length
limitation") amended the BCM2835 SPI driver with support for DMA
transfers whose buffers are not aligned to 4 bytes and require more than
one sglist entry.
When testing this feature with upcoming commits to speed up TX-only and
RX-only transfers, I noticed that SPI transmission sometimes breaks.
A function introduced by the commit, bcm2835_spi_transfer_prologue(),
performs one or two PIO transmissions as a prologue to the actual DMA
transmission. It turns out that the breakage goes away if the DONE bit
in the CS register is set when ending such a PIO transmission.
The DONE bit signifies emptiness of the TX FIFO. According to the spec,
the bit is of type RO, so writing it should never have any effect.
Perhaps the spec is wrong and the bit is actually of type RW1C.
E.g. the I2C controller on the BCM2835 does have an RW1C DONE bit which
needs to be cleared by the driver. Another, possibly more likely
explanation is that it's a hardware erratum since the issue does not
occur consistently.
Either way, amend bcm2835_spi_transfer_prologue() to always write the
DONE bit.
Usually a transmission is ended by bcm2835_spi_reset_hw(). If the
transmission was successful, the TX FIFO is empty and thus the DONE bit
is set when bcm2835_spi_reset_hw() reads the CS register. The bit is
then written back to the register, so we happen to do the right thing.
However if DONE is not set, e.g. because transmission is aborted with
a non-empty TX FIFO, the bit won't be written by bcm2835_spi_reset_hw()
and it seems possible that transmission might subsequently break. To be
on the safe side, likewise amend bcm2835_spi_reset_hw() to always write
the bit.

====================
Intel Wired LAN Driver Updates 2019-09-09
This series contains a variety of cold and hot savoury changes to Intel
drivers. Some of the fixes could be considered for stable even though
the author did not request it.
Hulk Robert cleans up (i.e. removes) a function that has no caller for
the iavf driver.
Radoslaw fixes an issue when there is no link in the VM after the
hypervisor is restored from a low-power state due to the driver not
properly restoring features in the device that had been disabled during
the suspension for ixgbevf.
Kai-Heng Feng modified e1000e to use mod_delayed_work() to help resolve
a hot plug speed detection issue by adding a deterministic 1 second
delay before running watchdog task after an interrupt.
Sasha moves functions around to avoid forward declarations, since the
forward declarations are not necessary for these static functions in
igc. Also added a check for igc during driver probe to validate the NVM
checksum. Cleaned up code defines that were not being used in the igc
driver. Adds support for IP generic transmit checksum offload in the
igc driver.
Updated the iavf kernel documentation by a developer with no life.
Jake provides another fm10k update to a local variable for ease of code
readability.
Mitch fixes the iavf driver to allow the VF to override the MAC address
set by the host, if the VF is in "trusted" mode.
Mauro S. M. Rodrigues provides several changes for i40e driver, first
with resolving hw_dbg usage and referencing a i40e_hw attribute. Also
implemented a debug macro using pr_debug, since the use of netdev_dbg
could cause a NULL pointer dereference during probe. Finally cleaned up
code that is no longer used or needed.
Firo Yang provides a change in the ixgbe driver to ensure we sync the
first fragment unconditionally to help resolve an issue seen in the XEN
environment when the upper network stack could receive an incomplete
network packet.
Mariusz adds a missing device to the i40e PCI table in the driver.
v2: Mauro S. M. Rodrigues updated patches 10 & 11 of the series based on
feedback from Jakub Kicinski. Also updated patch 13 description so
that the "Fixes:" tag was no wrapped.

In Xen environment, if Xen-swiotlb is enabled, ixgbe driver
could possibly allocate a page, DMA memory buffer, for the first
fragment which is not suitable for Xen-swiotlb to do DMA operations.
Xen-swiotlb have to internally allocate another page for doing DMA
operations. This mechanism requires syncing the data from the internal
page to the page which ixgbe sends to upper network stack. However,
since commit f3213d932173 ("ixgbe: Update driver to make use of DMA
attributes in Rx path"), the unmap operation is performed with
DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed.
Since the sync isn't performed, the upper network stack could receive
a incomplete network packet. By incomplete, it means the linear data
on the first fragment(between skb->head and skb->end) is invalid. So
we have to copy the data from the internal xen-swiotlb page to the page
which ixgbe sends to upper network stack through the sync operation.
More details from Alexander Duyck:
Specifically since we are mapping the frame with
DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result
a sync is not performed on an unmap and must be done manually as we
skipped it for the first frag. As such we need to always sync before
possibly performing a page unmap operation.

Since commit
'5098850c9b9b ("i40e/i40evf: i40e_register.h updates")'
it is no longer possible to trigger an EMP Reset from debugfs, but it's
possible to request it either way, to end up with a bad reset request:
echo empr > /sys/kernel/debug/i40e/0002\:01\:00.1/command
i40e 0002:01:00.1: debugfs: forcing EMPR
i40e 0002:01:00.1: bad reset request 0x00010000
So let's remove this piece of code and show the available valid commands
as it is when any invalid command is issued.

There are several uses of hw_dbg in the code, producing no output. This
patch implements it using dev_debug.
Initially the intention was to implement it using netdev_dbg, analogously
to what is done in ixgbe for instance. That approach was avoided due to
some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure
initialization causing NULL pointer dereference during the driver probe if
the debug messages were turned on as soon as the module is probed.
v2:
- Use dev_dbg instead of pr_debug, and take advantage of dev_name
instead of crafting pretty much the same device name locally as suggested
by Jakub Kicinski.

Pull regulator fixes from Mark Brown:
"This is obviouly very late, containing three small and simple driver
specific fixes.
The main one is the TWL fix, this fixes issues with cpufreq on the
PMICs used with BeagleBoard generation OMAP SoCs which had been broken
due to changes in the generic OPP code exposing a bug in the regulator
driver for these devices causing them to think that OPPs weren't
supported on the system.
Sorry about sending this so late, I hadn't registered that the TWL
issue manifested in cpufreq"

The mentioned function references a i40e_hw attribute, as parameter for
hw_dbg, but it doesn't exist in the function scope.
Fixes it by changing parameters from i40e_hmc_info to i40e_hw which can
retrieve the necessary i40e_hmc_info.
v2:
- Fixed reverse xmas tree code style issue as suggested by Jakub Kicinski

Allow the VF to override the "permanent" MAC address set by the host.
This allows bonding to work in the case where the administrator has set
the VF MAC.
Note that the VF must still be set to Trusted on the host if this change
is to be accepted by the PF driver.

In the function fm10k_xmit_frame_ring, we recently switched to using
the skb_frag_size accessor instead of directly using the size member of
the skb fragment.
This made the for loop slightly harder to read because it created a very
long line that is difficult to split up. Avoid this by using a local
variable in the for loop, so that we do not have to break the line on an
open parenthesis.

After hot plugging an 1Gbps Ethernet cable with 1Gbps link partner, the
MII_BMSR may report 10Mbps, renders the network rather slow.
The issue has much lower fail rate after commit 59653e6497d1 ("e1000e:
Make watchdog use delayed work"), which essentially introduces some
delay before running the watchdog task.
But there's still a chance that the hot plugging event and the queued
watchdog task gets run at the same time, then the original issue can be
observed once again.
So let's use mod_delayed_work() to add a deterministic 1 second delay
before running watchdog task, after an interrupt.
