Pull perf fixes from Ingo Molnar:
"I'd like to apologize for this very late pull request: I was dithering
through the week whether to send the fixes, and then yesterday Jiri's
crash fix for a regression introduced in this cycle clearly marked
perf/urgent as 'must merge now'.
Most of the commits are tooling fixes, plus there's three kernel fixes
via four commits:
- race fix in the Intel PEBS code
- fix an AUX bug and roll back a previous attempt
- fix AMD family 17h generic HW cache-event perf counters
The largest diffstat contribution comes from the AMD fix - a new event
table is introduced, which is a fairly low risk change but has a large
linecount"

In normal queue cleanup path, hctx is released after request queue
is freed, see blk_mq_release().
However, in __blk_mq_update_nr_hw_queues(), hctx may be freed because
of hw queues shrinking. This way is easy to cause use-after-free,
because: one implicit rule is that it is safe to call almost all block
layer APIs if the request queue is alive; and one hctx may be retrieved
by one API, then the hctx can be freed by blk_mq_update_nr_hw_queues();
finally use-after-free is triggered.
Fixes this issue by always freeing hctx after releasing request queue.
If some hctxs are removed in blk_mq_update_nr_hw_queues(), introduce
a per-queue list to hold them, then try to resuse these hctxs if numa
node is matched.

I got an interesting report [0] that after resuming from hibernation
the link has 100Mbps instead of 1Gbps. Reason is that another OS has
been used whilst Linux was hibernated. And this OS speeds down the link
due to WoL. Therefore, when resuming, we shouldn't expect that what
the PHY advertises is what it did when hibernating.
Easiest way to do this is removing state PHY_RESUMING. Instead always
go via PHY_UP that configures PHY advertisement.

When probing the phy device we set sym and asym pause in the "supported"
bitmap (unless the PHY tells us otherwise). However we don't know yet
whether the MAC supports pause. Simply copying phy->supported to
phy->advertising will trigger advertising pause, and that's not
what we want. Therefore add phy_advertise_supported() that copies all
modes but doesn't touch the pause bits.
In phy_support_(a)sym_pause we shouldn't set any bits in the supported
bitmap because we may set a bit the PHY intentionally disabled.
Effective pause support should be the AND-combined PHY and MAC pause
capabilities. If the MAC supports everything, then it's only relevant
what the PHY supports. If MAC supports sym pause only, then we have to
clear the asym bit in phydev->supported.
Copy the pause flags only and don't touch the modes, because a driver
may have intentionally removed a mode from phydev->advertising.

kobject_init() always succeeds and sets the reference count to 1.
It allows to always free the structures via kobject_put() and
the related release callback.
Note that the custom kobject state handling was used only
because we did not know that kobject_put() can and actually
should get called even when kobject_init_and_add() fails.
The patch should not change the existing behavior.

This patch provides an arch option, ARCH_SUSPEND_NONZERO_CPU, to
opt-in to allowing suspend to occur on one of the housekeeping CPUs
rather than hardcoded CPU0.
This will allow CPU0 to be a nohz_full CPU with a later change.
It may be possible for platforms with hardware/firmware restrictions
on suspend/wake effectively support this by handing off the final
stage to CPU0 when kernel housekeeping is no longer required. Another
option is to make housekeeping / nohz_full mask dynamic at runtime,
but the complexity could not be justified at this time.

VLAN filtering cannot be properly disabled in SJA1105. So in order to
emulate the "no VLAN awareness" behavior (not dropping traffic that is
tagged with a VID that isn't configured on the port), we need to hack
another switch feature: programmable TPID (which is 0x8100 for 802.1Q).
We are reprogramming the TPID to a bogus value which leaves the switch
thinking that all traffic is untagged, and therefore accepts it.
Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is
installed again, and the switch starts identifying 802.1Q-tagged
traffic.

This provides an unified API for accessing register bit fields
regardless of memory layout. The basic unit of data for these API
functions is the u64. The process of transforming an u64 from native CPU
encoding into the peripheral's encoding is called 'pack', and
transforming it from peripheral to native CPU encoding is 'unpack'.

This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.
Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found
in DT.
This simplifies driver probe path and particularly phy handling.

On RT, iommu_dma_map_msi_msg() may be called from non-preemptible
context. This will lead to a splat with CONFIG_DEBUG_ATOMIC_SLEEP as
the function is using spin_lock (they can sleep on RT).
iommu_dma_map_msi_msg() is used to map the MSI page in the IOMMU PT
and update the MSI message with the IOVA.
Only the part to lookup for the MSI page requires to be called in
preemptible context. As the MSI page cannot change over the lifecycle
of the MSI interrupt, the lookup can be cached and re-used later on.
iomma_dma_map_msi_msg() is now split in two functions:
- iommu_dma_prepare_msi(): This function will prepare the mapping
in the IOMMU and store the cookie in the structure msi_desc. This
function should be called in preemptible context.
- iommu_dma_compose_msi_msg(): This function will update the MSI
message with the IOVA when the device is behind an IOMMU.

When an MSI doorbell is located downstream of an IOMMU, it is required
to swizzle the physical address with an appropriately-mapped IOVA for any
device attached to one of our DMA ops domain.
At the moment, the allocation of the mapping may be done when composing
the message. However, the composing may be done in non-preemtible
context while the allocation requires to be called from preemptible
context.
A follow-up change will split the current logic in two functions
requiring to keep an IOMMU cookie per MSI.
A new field is introduced in msi_desc to store an IOMMU cookie. As the
cookie may not be required in some configuration, the field is protected
under a new config CONFIG_IRQ_MSI_IOMMU.
A pair of helpers has also been introduced to access the field.

There are two problems with WARN_ON() here. One: It is not ratelimited.
Two: We don't see which adapter was used when trying to transfer
something when already suspended. Implement a custom ratelimit once per
adapter and use dev_WARN there. This fixes both issues. Drawback is that
we don't see if multiple drivers are trying to transfer with the same
adapter while suspended. They need to be discovered one after the other
now. This is better than a high CPU load because a really broken driver
might try to resend endlessly.

Pull io_uring fixes from Jens Axboe:
"This is mostly io_uring fixes/tweaks. Most of these were actually done
in time for the last -rc, but I wanted to ensure that everything
tested out great before including them. The code delta looks larger
than it really is, as it's mostly just comment additions/changes.
Outside of the comment additions/changes, this is mostly removal of
unnecessary barriers. In all, this pull request contains:
- Tweak to how we handle errors at submission time. We now post a
completion event if the error occurs on behalf of an sqe, instead
of returning it through the system call. If the error happens
outside of a specific sqe, we return the error through the system
call. This makes it nicer to use and makes the "normal" use case
behave the same as the offload cases. (me)
- Fix for a missing req reference drop from async context (me)
- If an sqe is submitted with RWF_NOWAIT, don't punt it to async
context. Return -EAGAIN directly, instead of using it as a hint to
do async punt. (Stefan)
- Fix notes on barriers (Stefan)
- Remove unnecessary barriers (Stefan)
- Fix potential double free of memory in setup error (Mark)
- Further improve sq poll CPU validation (Mark)
- Fix page allocation warning and leak on buffer registration error
(Mark)
- Fix iov_iter_type() for new no-ref flag (Ming)
- Fix a case where dio doesn't honor bio no-page-ref (Ming)"

A lot of ->destroy_inode() instances end with call_rcu() of a callback
that does RCU-delayed part of freeing. Introduce a new method for
doing just that, with saner signature.
Rules:
->destroy_inode ->free_inode
f g immediate call of f(),
RCU-delayed call of g()
f NULL immediate call of f(),
no RCU-delayed calls
NULL g RCU-delayed call of g()
NULL NULL RCU-delayed default freeing
IOW, NULL ->free_inode gives the same behaviour as now.
Note that NULL, NULL is equivalent to NULL, free_inode_nonrcu; we could
mandate the latter form, but that would have very little benefit beyond
making rules a bit more symmetric. It would break backwards compatibility,
require extra boilerplate and expected semantics for (NULL, NULL) pair
would have no use whatsoever...

This converts the EP93xx SPI master driver to use GPIO
descriptors for chip select handling.
EP93xx was using platform data to pass in GPIO lines,
by converting all board files to use GPIO descriptor
tables the core will look up the GPIO lines from the
SPI device in the same manner as for device tree.
