This reverts commit aa6f8dcbab.
It turns out this breaks at least the ath9k wireless driver, and
possibly others.
What the ath9k driver does on packet receive is to set up the DMA
transfer with:
int ath_rx_init(..)
..
bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
common->rx_bufsize,
DMA_FROM_DEVICE);
and then the receive logic (through ath_rx_tasklet()) will fetch
incoming packets
static bool ath_edma_get_buffers(..)
..
dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
if (ret == -EINPROGRESS) {
/*let device gain the buffer again*/
dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
common->rx_bufsize, DMA_FROM_DEVICE);
return false;
}
and it's worth noting how that first DMA sync:
dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
is there to make sure the CPU can read the DMA buffer (possibly by
copying it from the bounce buffer area, or by doing some cache flush).
The iommu correctly turns that into a "copy from bounce bufer" so that
the driver can look at the state of the packets.
In the meantime, the device may continue to write to the DMA buffer, but
we at least have a snapshot of the state due to that first DMA sync.
But that _second_ DMA sync:
dma_sync_single_for_device(..DMA_FROM_DEVICE);
is telling the DMA mapping that the CPU wasn't interested in the area
because the packet wasn't there. In the case of a DMA bounce buffer,
that is a no-op.
Note how it's not a sync for the CPU (the "for_device()" part), and it's
not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab
broke: it made the code bounce the buffer unconditionally, and changed
the DMA_FROM_DEVICE to just unconditionally and illogically be
DMA_TO_DEVICE.
[ Side note: purely within the confines of the swiotlb driver it wasn't
entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
it uses just a swiotlb_bounce() helper that doesn't care about the
whole distinction of who the sync is for - only which direction to
bounce.
So it took the "sync for device" to mean that the CPU must have been
the one writing, and thought it meant DMA_TO_DEVICE. ]
Also note how the commentary in that commit was wrong, probably due to
that whole confusion, claiming that the commit makes the swiotlb code
"bounce unconditionally (that is, also
when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
data from the swiotlb buffer"
which is nonsensical for two reasons:
- that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
exactly when it always did - and should do - the bounce.
- since this is a sync for the device (not for the CPU), we're clearly
fundamentally not coping back stale data from the bounce buffers at
all, because we'd be copying *to* the bounce buffers.
So that commit was just very confused. It confused the direction of the
synchronization (to the device, not the cpu) with the direction of the
DMA (from the device).

If phy driver happens to read BMCR register during reset, phy speed will
be updated to 10Mpbs as BMCR register value is 0. So it may call phy can
not link up if previous speed is not 10Mpbs.
To fix this problem, function hclge_mdio_read() should return -EBUSY if

The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.
The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.
Fix it by reopening the VXLAN device instead of its physical device.

A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
Broadcom UniMAC MDIO controller as not completing the turn around
properly since the PHY expects 65 MDC clock cycles to complete a write
cycle, and the MDIO controller was only sending 64 MDC clock cycles as
determined by looking at a scope shot.
This would make the subsequent read fail with the UniMAC MDIO controller
command field having MDIO_READ_FAIL set and we would abort the
brcm_fet_config_init() function and thus not probe the PHY at all.
After issuing a software reset, wait for at least 1ms which is well
above the 1us reset delay advertised by the datasheet and issue a dummy
read to let the PHY turn around the line properly. This read
specifically ignores -EIO which would be returned by MDIO controllers
checking for the line being turned around.
If we have a genuine reaad failure, the next read of the interrupt
status register would pick it up anyway.

When clk_put() is called we don't make another clk_set_rate() call to
re-evaluate the rate boundaries. This is unlike clk_set_rate_range()
that evaluates the rate again each time it is called.
However, clk_put() is essentially equivalent to clk_set_rate_range()
since after clk_put() completes the consumer's boundaries shouldn't be
enforced anymore.
Let's add a call to clk_set_rate_range() in clk_put() to make sure those
rate boundaries are dropped and the clock provider drivers can react.
Also add a few tests to make sure this case is covered.

A bug recently affected the Tegra30 where calling clk_set_rate_range()
on a clock would make it change its rate to the minimum.
This was due to the clock in question being a mux that was orphan at
registration, which lead to the clk_core req_rate being 0, and the
clk_set_rate_range() function then calling clk_set_rate() with req_rate,
effectively making that clock running at the minimum rate allowed, even
though the initial rate was within that range.
Make a test suite to create a mux initially orphan, and then make sure
that if our clock rate was initially within a given range, then
enforcing that range won't affect it.

This patch refines the process, PF can set VF VLAN direclty,
and then notify the VF. If VF is resetting at that time, the
notify may be dropped, so VF should query it after reset finished.

Currently, Port base vlan is initiated by PF and configured to its VFs,
by using command "ip link set <pf name> vf <vf id> vlan <vlan id>".
When a global reset was triggered, the hardware vlan table and the soft
recorded vlan information will be cleared by PF, and restored them until
VFs were ready. There is a short time window between the table had been
cleared and before table restored. If configured a new port base vlan tag
at this moment, driver will check the soft recorded vlan information,
and find there hasn't the old tag in it, which causing a warning print.
Due to the port base vlan is managed by PF, so the VFs's port base vlan
restoring should be handled by PF when PF was ready.
This patch fixes it.

If the MAC address A is configured to vport A and then vport B. The MAC
address of vport A in the hardware becomes invalid. If the address of
vport A is changed to MAC address B, the driver needs to delete the MAC
address A of vport A. Due to the MAC address A of vport A has become
invalid in the hardware entry, so "-ENOENT" is returned. In this case, the
"used_umv_size" value recorded in driver is not updated. As a result, the
MAC entry status of the software is inconsistent with that of the hardware.
Therefore, the driver updates the umv size even if the MAC entry cannot be
found. Ensure that the software and hardware status is consistent.

is_xen_pmu() is taking the cpu number as parameter, but it is not using
it. Instead it just tests whether the Xen PMU initialization on the
current cpu did succeed. As this test is done by checking a percpu
pointer, preemption needs to be disabled in order to avoid switching
the cpu while doing the test. While resuming from suspend() this seems
not to be the case:

Fix that by replacing is_xen_pmu() by a simple boolean variable which
reflects the Xen PMU initialization state on cpu 0.
Modify xen_pmu_init() to return early in case it is being called for a
cpu other than cpu 0 and the boolean variable not being set.

If a xen domain with at least two VCPUs has a PCI device attached which
enters the D3hot state during suspend, the kernel may hang while
resuming, depending on the core on which an async resume task gets
scheduled.
The bug occurs because xen's do_suspend calls dpm_resume_start while
only the timer of the boot CPU has been resumed (when xen_suspend called
syscore_resume), before calling xen_arch_suspend to resume the timers of
the other CPUs. This breaks pci_dev_d3_sleep.
Thus this patch moves the call to xen_arch_resume before the call to
dpm_resume_start, eliminating the hangs and restoring the stack-like
structure of the suspend/restore procedure.

Linus pointed out the benefits of C99 some years ago, especially variable
declarations in loops [1]. At that time, we were not ready for the
migration due to old compilers.
Recently, Jakob Koschel reported a bug in list_for_each_entry(), which
leaks the invalid pointer out of the loop [2]. In the discussion, we
agreed that the time had come. Now that GCC 5.1 is the minimum compiler
version, there is nothing to prevent us from going to -std=gnu99, or even
straight to -std=gnu11.
Discussions for a better list iterator implementation are ongoing, but
this patch set must land first.

When registering a clock that doesn't have a recalc_rate implementation,
and doesn't have its parent registered yet, we initialize the clk_core
rate and 'req_rate' fields to 0.
The rate field is later updated when the parent is registered in
clk_core_reparent_orphans_nolock() using __clk_recalc_rates(), but the
'req_rate' field is never updated.
This leads to an issue in clk_set_rate_range() and clk_put(), since
those functions will call clk_set_rate() with the content of 'req_rate'
to provide drivers with the opportunity to change the rate based on the
new boundaries. In this case, we would call clk_set_rate() with a rate
of 0, effectively enforcing the minimum allowed for this clock whenever
we would call one of those two functions, even though the actual rate
might be within range.
Let's fix this by setting 'req_rate' in
clk_core_reparent_orphans_nolock() with the rate field content just
updated by the call to __clk_recalc_rates().
Fixes: 1c8e600440 ("clk: Add rate constraints to clocks")

The perf lock command has nothing to symbolize and lock names come
from the tracepoint. Moreover, kernel symbols are available even the
--synth=no option is given.
This will reduce the startup time by avoiding unnecessary synthesis.
