This userspace program includes UAPI headers exported to usr/include/.
'make headers' always works for the target architecture (i.e. the same
architecture as the kernel), so the sample program should be built for
the target as well. Kbuild now supports 'userprogs' for that.
I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because
$(CC) may not provide libc.

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.

The original qcom kernel changed the PDM GPIOs to be pull-down
during sleep at some point. Reportedly this was done because
there was some "leakage at PDM outputs during sleep":
https://source.codeaurora.org/quic/la/kernel/msm-3.10/commit/?id=0f87e08c1cd3e6484a6f7fb3e74e37340bdcdee0
I cannot say how effective this is, but everything seems to work
fine with this change so let's apply the same to mainline just
to be sure.

msm8916-pins.dtsi specifies "bias-pull-none" for most of the audio
pin configurations. This was likely copied from the qcom kernel fork
where the same property was used for these audio pins.
However, "bias-pull-none" actually does not exist at all - not in
mainline and not in downstream. I can only guess that the original
intention was to configure "no pull", i.e. bias-disable.
Change it to that instead.

As of commit 4ff028f6c108 ("ASoC: qcom: lpass-cpu: Make I2S SD lines
configurable"), lpass now supports children nodes to configure the
MI2S SD lines to use for one of the I2S ports. For example:
lpass@7708000 {
dai@3 {
reg = <MI2S_QUATERNARY>;
qcom,playback-sd-lines = <1>;
};
};
The "reg" property refers to the DAI number in this case,
so we need to set #address-cells and #size-cells appropriately
to avoid DTC warnings.

The ufs-qcom driver checks that the name matches the androidboot.bootdevice
parameter provided by the bootloader, which uses the name ufshc. Without
this change UFS fails to probe.
I think this is broken behavior from the ufs-qcom driver, but using the
name ufshc is consistent with dts for sdm845/sm8150/etc.

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"

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:
BUG: kernel NULL pointer dereference, address: 00000000000000b0

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.

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.
