Since hists__init doesn't set the destructor of hists_evsel (which is an
extended evsel structure), when hists_evsel is released, the extended
part of the hists_evsel is not deleted (note that the hists_evsel object
itself is freed).
This fixes it to add a destructor for hists__evsel and to set it up.

Boris reported that 'perf top' is unusable on his default 'black on
white' terminal, which uses (eye friendly) light-grey as a background
color.
The reason is that the TUI cursor for the current selection line uses
HE_COLORSET_SELECTED, and that has a default background color of
'lightgrey' - which is a common terminal background choice and thus
the colors conflict.
Use yellow as the background color instead: that should be an uncommon
terminal background, yet it's still ergonomic on both black and
white/grey terminals.
[ It would be a better solution to straight out detect color
collisions and resolve them reasonably by converting them to RGB and
calculating color space distances, but I was unable to find
proper documentation for SLtt_get_color_object() to recover the
current color scheme so I gave up ... Yellow works well enough. ]

Lenovo Thinkpad T440s suffers from constant background noises, and it
seems to be a generic hardware issue on this model:
https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-noise/td-p/1339883
As the noise comes from the analog loopback path, disabling the path
is the easy workaround.
Also, the machine gives significant cracking noises at PM suspend. A
workaround found by trial-and-error is to disable the shutup callback
currently used for ALC269-variant.
This patch addresses these noise issues by introducing a new fixup
chain. Although the same workaround might be applicable to other
Thinkpad models, it's applied only to T440s (17aa:220c) in this patch,
so far, just to be safe (you chicken!). As a compromise, a new model
option string "tp440" is provided now, though, so that owners of other
Thinkpad models can test it more easily.

This reverts commit 527d10ef3a.
The reverted commit breaks cxlflash devices following an EEH reset (and
possibly other cxl devices, however this has not been tested).
The reverted commit changed the behaviour of eeh_reset_device() so that PHB
PEs are not unfrozen following the completion of the reset. This should not
be problematic, as no device resources should have been associated with the
PHB PE.
However, when attempting to load the cxlflash driver after a reset, the
driver attempts to read Vital Product Data through a call to
pci_read_vpd() (which is called on the physical cxl device, not on the
virtual AFU device). pci_read_vpd() in turn attempts to read from the cxl
device's config space. This fails, as the PE it's trying to read from is
still frozen. In turn, the driver gets an -ENODEV and fails to initialise.
It appears this issue only affects some parts of the VPD area, as "lspci
-vvv", which only reads a subset of the VPD bytes, is not broken by the
original patch.
At this stage, we don't fully understand why we're trying to read a frozen
PE, and we don't know how this affects other cxl devices. It is possible
that there is an underlying bug in the cxl driver or the powerpc CAPI
support code, or alternatively a bug in the PCI resource allocation/mapping
code that is incorrectly mapping resources to PE#0.
As such, this fix is incomplete, however it is necessary to prevent a
serious regression in CAPI support.
In the meantime, revert the commit, especially as it was intended to be a
non-functional change.

This file was originally cloned off of the MPC8641D-HPCN reference
platform, which actually had a PHY IRQ line connected. However this
board does not. The bogus entry was largely inert and went undetected
until commit 321beec504 ("net: phy: Use
interrupts when available in NOLINK state") was added to the tree.
With the above commit, the board fails to NFS boot since it sits waiting
for a PHY IRQ event that of course never arrives. Removing the bogus

The remove_keys() logic is performed as garbage collection task. Such
task is intended to be run when no other active processes are running.
The need_resched() will return TRUE if there are user tasks to be
activated in near future.
In such case, we don't execute remove_keys() and postpone
the garbage collection work to try to run in next cycle,
in order to free CPU resources to other tasks.
The possible pseudo-code to trigger such scenario:
1. Allocate a lot of MR to fill the cache above the limit.
2. Wait a small amount of time "to calm" the system.
3. Start CPU extensive operations on multi-node cluster.
4. Expect performance degradation during MR cache shrink operation.

For block devices the pagecache is associated with the inode
on bdevfs, not with the aliasing ones on the mountable filesystems.
The latter have its own ->i_data empty and ->i_mapping pointing
to the (unique per major/minor) bdevfs inode. That guarantees
cache coherence between all block device inodes with the same
device number.
Eviction of an alias inode has no business trying to evict the
pages belonging to bdevfs one; moreover, ->i_mapping is only
safe to access when the thing is opened. At the time of
->evict_inode() the victim is definitely *not* opened. We are
about to kill the address space embedded into struct inode
(inode->i_data) and that's what we need to empty of any pages.
9p instance tries to empty inode->i_mapping instead, which is
both unsafe and bogus - if we have several device nodes with
the same device number in different places, closing one of them
should not try to empty the (shared) page cache.
Fortunately, other instances in the tree are OK; they are
evicting from &inode->i_data instead, as 9p one should.

A new SRP target has been observed to respond to Send CM REQ

__unflatten_device_tree() calls unflatten_dt_node(), which declares

One of the callers of __unflatten_device_tree(), unflatten_device_tree(),

Without this protection, errors such as the following may be seen.

If musb_init_controller fails at musb_platform_init, we have already
called pm_runtime_irq_safe for musb and that causes the pm runtime count
to be enabled for parent before the parent has completed initialization.
This causes pm to stop working as on unload nothing gets idled.
This issue can be reproduced at least with:
# modprobe omap2430
HS USB OTG: no transceiver configured
musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517
# modprobe phy-twl4030-usb
# rmmod omap2430
And after the steps above omap2430 will block deeper idle states on
omap3.
To fix this, let's not enable pm runtime until we need to and the
parent has been initialized. Note that this does not fix the issue of
PM being broken for musb during runtime.

How about the patch below ? In that version of the ib_sg_to_pages() fix
these concerns have been addressed and additionally to more bugs have been fixed.
------------
[PATCH] IB core: Fix ib_sg_to_pages()
Fix the code for detecting gaps. A gap occurs not only if the
second or later scatterlist element is not aligned but also if
any scatterlist element other than the last does not end at a
page boundary.
In the code for coalescing contiguous elements, ensure that
mr->length is correct and that last_page_addr is up-to-date.
Ensure that this function returns a negative
error code instead of zero if the first set_page() call fails.
Fixes: commit 4c67e2bfc8 ("IB/core: Introduce new fast registration API")

After dma_map_sg() has been called the return value of that function
must be used as the number of elements in the scatterlist instead of
scsi_sg_count().
