selftests/mm: fix charge_reserved_hugetlb.sh test

[ Upstream commit c41a701d18efe6b8aa402efab16edbaba50c9548 ]

Currently, running the charge_reserved_hugetlb.sh selftest we can
sometimes observe something like:

$ ./charge_reserved_hugetlb.sh -cgroup-v2
...
write_result is 0
After write:
hugetlb_usage=0
reserved_usage=10485760
killing write_to_hugetlbfs
Received 2.
Deleting the memory
Detach failure: Invalid argument
umount: /mnt/huge: target is busy.

Both cases are issues in the test.

While the unmount error seems to be racy, it will make the test fail:
$ ./run_vmtests.sh -t hugetlb
...
# [FAIL]
not ok 10 charge_reserved_hugetlb.sh -cgroup-v2 # exit=32

The issue is that we are not waiting for the write_to_hugetlbfs process to
quit. So it might still have a hugetlbfs file open, about which umount is
not happy. Fix that by making "killall" wait for the process to quit.

The other error ("Detach failure: Invalid argument") does not seem to
result in a test error, but is misleading. Turns out write_to_hugetlbfs.c
unconditionally tries to cleanup using shmdt(), even when we only
mmap()'ed a hugetlb file. Even worse, shmaddr is never even set for the
SHM case. Fix that as well.

With this change it seems to work as expected.

selftests/mm: fix awk usage in charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh that may cause error

According to the awk manual, the -e option does not need to be specified
in front of 'program' (unless you need to mix program-file).

The redundant -e option can cause error when users use awk tools other
than gawk (for example, mawk does not support the -e option).

Error Example:
awk: not an option: -e

ASoC: Updates for v6.6

Here's an initial batch of updates for ASoC for this release cycle.
We've got a bunch of new drivers in here, a bit of core work from
Morimoto-san and quite a lot of janitorial work. There's several
updates that pull in changes from other subsystems in order to build
on them:

- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes.
- Create a library function for intlog10() and use it in the NAU8825
driver.
- Include the ASoC tests, including the topology tests, in the default
KUnit full test coverage. This also involves enabling UML builds of
ALSA since that's the default KUnit test environment which pulls in
the addition of some stubs to the driver.
- More factoring out from Morimoto-san.
- Convert a lot of drivers to use the more modern maple tree register
cache.
- Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.

selftests/mm: give scripts execute permission

When run under run_vmtests.sh, test scripts were failing to run with
"permission denied" due to the scripts not being executable.

It is also annoying not to be able to directly invoke run_vmtests.sh,
which is solved by giving also it the execute permission.
