This reverts commit e0b250b57dcf403529081e5898a9de717f96b76b,
which broke build systems that need to install files to a certain
path, but do not set INSTALL_MOD_PATH when invoking 'make install'.
$ make INSTALL_PATH=/tmp/destdir install
mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied
Makefile:1342: recipe for target '_builtin_inst_' failed
make: *** [_builtin_inst_] Error 1
While modules.builtin is useful also for CONFIG_MODULES=n, this change
in the behavior is quite unexpected. Maybe "make modules_install"
can install modules.builtin irrespective of CONFIG_MODULES as Jonas
originally suggested.
Anyway, that commit should be reverted ASAP.

When preallocated service calls are being discarded, they're passed to
->discard_new_call() to have the caller clean up any attached higher-layer
preallocated pieces before being marked completed. However, the act of
marking them completed now invokes the call's notification function - which
causes a problem because that function might assume that the previously
freed pieces of memory are still there.
Fix this by setting a dummy notification function on the socket after
calling ->discard_new_call().
This results in the following kasan message when the kafs module is
removed.

up with the occasional netdev watchdog Tx Timeout complaint.
The old method of using netif_trans_update() works fine for

Pull libnvdimm updates from Dan Williams:
"A feature (papr_scm health retrieval) and a fix (sysfs attribute
visibility) for v5.8.
Vaibhav explains in the merge commit below why missing v5.8 would be
painful and I agreed to try a -rc2 pull because only cosmetics kept
this out of -rc1 and his initial versions were posted in more than
enough time for v5.8 consideration:
'These patches are tied to specific features that were committed to
customers in upcoming distros releases (RHEL and SLES) whose
time-lines are tied to 5.8 kernel release.
Being able to track the health of an nvdimm is critical for our
customers that are running workloads leveraging papr-scm nvdimms.
Missing the 5.8 kernel would mean missing the distro timelines and
shifting forward the availability of this feature in distro kernels
by at least 6 months'
Summary:
- Fix the visibility of the region 'align' attribute.
The new unit tests for region alignment handling caught a corner
case where the alignment cannot be specified if the region is
converted from static to dynamic provisioning at runtime.
- Add support for device health retrieval for the persistent memory
supported by the papr_scm driver.
This includes both the standard sysfs "health flags" that the nfit
persistent memory driver publishes and a mechanism for the ndctl
tool to retrieve a health-command payload"

leak in case of error in 'imx_pinctrl_probe()'"
This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9.
After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared

iomuxc and iomuxc-lpsr which share select_input register for

for the first time. Then, next time when probe the iomuxc, API
devm_platform_ioremap_resource() will also use the API
devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
again, then cause issue, log like below:

- a missing lock in set_direct_map_*(), which due to a recent lockdep
change started asserting.

The fileserver probe timer, net->fs_probe_timer, isn't cancelled when
the kafs module is being removed and so the count it holds on
net->servers_outstanding doesn't get dropped..
This causes rmmod to wait forever. The hung process shows a stack like:
afs_purge_servers+0x1b5/0x23c [kafs]
afs_net_exit+0x44/0x6e [kafs]
ops_exit_list+0x72/0x93
unregister_pernet_operations+0x14c/0x1ba
unregister_pernet_subsys+0x1d/0x2a
afs_exit+0x29/0x6f [kafs]
__do_sys_delete_module.isra.0+0x1a2/0x24b
do_syscall_64+0x51/0x95
entry_SYSCALL_64_after_hwframe+0x44/0xa9
Fix this by:
(1) Attempting to cancel the probe timer and, if successful, drop the
count that the timer was holding.
(2) Make the timer function just drop the count and not schedule the
prober if the afs portion of net namespace is being destroyed.
Also, whilst we're at it, make the following changes:
(3) Initialise net->servers_outstanding to 1 and decrement it before
waiting on it so that it doesn't generate wake up events by being
decremented to 0 until we're cleaning up.
(4) Switch the atomic_dec() on ->servers_outstanding for ->fs_timer in
afs_purge_servers() to use the helper function for that.

Fix afs_do_lookup()'s fallback case for when FS.InlineBulkStatus isn't
supported by the server.
In the fallback, it calls FS.FetchStatus for the specific vnode it's
meant to be looking up. Commit b6489a49f7b7 broke this by renaming one
of the two identically-named afs_fetch_status_operation descriptors to
something else so that one of them could be made non-static. The site
that used the renamed one, however, wasn't renamed and didn't produce
any warning because the other was declared in a header.
Fix this by making afs_do_lookup() use the renamed variant.
Note that there are two variants of the success method because one is
called from ->lookup() where we may or may not have an inode, but can't
call iget until after we've talked to the server - whereas the other is
called from within iget where we have an inode, but it may or may not be
initialised.
The latter variant expects there to be an inode, but because it's being
called from there former case, there might not be - resulting in an oops
like the following:

Since commit 9e343b467c70 ("READ_ONCE: Enforce atomicity for
{READ,WRITE}_ONCE() memory accesses") it is not possible anymore to
use READ_ONCE() to access complex page table entries like the one
defined for powerpc 8xx with 16k size pages.
Define a ptep_get() helper that architectures can override instead
of performing a READ_ONCE() on the page table entry pointer.

wenxu says:
====================
several fixes for indirect flow_blocks offload
v2:
patch2: store the cb_priv of representor to the flow_block_cb->indr.cb_priv
in the driver. And make the correct check with the statments
this->indr.cb_priv == cb_priv
patch4: del the driver list only in the indriect cleanup callbacks
v3:
add the cover letter and changlogs.
v4:
collapsed 1/4, 2/4, 4/4 in v3 to one fix
Add the prepare patch 1 and 2
v5:
patch1: place flow_indr_block_cb_alloc() right before
flow_indr_dev_setup_offload() to avoid moving flow_block_indr_init()
This series fixes commit 1fac52da5942 ("net: flow_offload: consolidate
indirect flow_block infrastructure") that revists the flow_block
infrastructure.
patch #1 #2: prepare for fix patch #3
add and use flow_indr_block_cb_alloc/remove function
patch #3: fix flow_indr_dev_unregister path
If the representor is removed, then identify the indirect flow_blocks
that need to be removed by the release callback and the port representor
structure. To identify the port representor structure, a new
indr.cb_priv field needs to be introduced. The flow_block also needs to
be removed from the driver list from the cleanup path
patch#4 fix block->nooffloaddevcnt warning dmesg log.
When a indr device add in offload success. The block->nooffloaddevcnt
should be 0. After the representor go away. When the dir device go away
the flow_block UNBIND operation with -EOPNOTSUPP which lead the warning
demesg log.
The block->nooffloaddevcnt should always count for indr block.
even the indr block offload successful. The representor maybe
gone away and the ingress qdisc can work in software mode.

If the representor is removed, then identify the indirect flow_blocks
that need to be removed by the release callback and the port representor
structure. To identify the port representor structure, a new
indr.cb_priv field needs to be introduced. The flow_block also needs to
be removed from the driver list from the cleanup path.

VLAN tag insertion/extraction offload is correctly
activated at probe time but deactivation of this feature
(i.e. via ethtool) is broken. Toggling works only for
Tx/Rx ring 0 of a PF, and is ignored for the other rings,
including the VF rings.
To fix this, the existing VLAN offload toggling code
was extended to all the rings assigned to a netdevice,
instead of the default ring 0 (likely a leftover from the
early validation days of this feature). And the code was
moved to the common set_features() function to fix toggling
for the VF driver too.

rxrpc: Performance drop fix and other fixes
Here are three fixes for rxrpc:
(1) Fix a trace symbol mapping. It doesn't seem to let you map to "".
(2) Fix the handling of the remote receive window size when it increases
beyond the size we can support for our transmit window.
(3) Fix a performance drop caused by retransmitted packets being
accidentally marked as already ACK'd.

Include the papr_scm health retrieval feature for v5.8-rc2. The
functionality was initially posted well in advance of the merge window,
but review comments and a late build-bot warning kept them out of the
v5.8-rc1 libnvdimm pull request.
Vaibhav notes:
These patches are tied to specific features that were committed to
customers in upcoming distros releases (RHEL and SLES) whose time-lines
are tied to 5.8 kernel release.
Being able to track the health of an nvdimm is critical for our
customers that are running workloads leveraging papr-scm nvdimms.
Missing the 5.8 kernel would mean missing the distro timelines and
shifting forward the availability of this feature in distro kernels by
at least 6 months.

net: phy: MDIO bus scanning fixes
This patch series fixes two problems with the current MDIO bus scanning
logic which was identified while moving from 4.9 to 5.4 on devices that
do rely on scanning the MDIO bus at runtime because they use pluggable
cards.
Changes in v2:
- added comment explaining the special value of -ENODEV
- added Andrew's Reviewed-by tag

Commit 02a6efcab675 ("net: phy: allow scanning busses with missing
phys") added a special condition to return -ENODEV in case -ENODEV or
-EIO was returned from the first read of the MII_PHYSID1 register.
In case the MDIO bus data line pull-up is not strong enough, the MDIO
bus controller will not flag this as a read error. This can happen when
a pluggable daughter card is not connected and weak internal pull-ups
are used (since that is the only option, otherwise the pins are
floating).
The second read of MII_PHYSID2 will be correctly flagged an error
though, but now we will return -EIO which will be treated as a hard
error, thus preventing MDIO bus scanning loops to continue succesfully.
Apply the same logic to both register reads, thus allowing the scanning
logic to proceed.

Commit 209c65b61d94 ("drivers/of/of_mdio.c:fix of_mdiobus_register()")
introduced a break of the loop on the premise that a successful
registration should exit the loop. The premise is correct but not to
code, because rc && rc != -ENODEV is just a special error condition,
that means we would exit the loop even with rc == -ENODEV which is
absolutely not correct since this is the error code to indicate to the
MDIO bus layer that scanning should continue.
Fix this by explicitly checking for rc = 0 as the only valid condition
to break out of the loop.
