Recursive make commands should always use the variable MAKE, not the

If zram-generator package is installed and works, then we can not remove
zram module because zram swap is being used. This case needs a clean zram
environment, change this test by using hot_add/hot_remove interface. So
even zram device is being used, we still can add zram device and remove
them in cleanup.
The two interface was introduced since kernel commit 6566d1a32bf7("zram:
add dynamic device add/remove functionality") in v4.2-rc1. If kernel
supports these two interface, we use hot_add/hot_remove to slove this
problem, if not, just check whether zram is being used or built in, then
skip it on old kernel.

zram01 uses `free -m` to measure zram memory usage. The results are no
sense because they are polluted by all running processes on the system.
We Should only calculate the free memory delta for the current process.
So use the third field of /sys/block/zram<id>/mm_stat to measure memory
usage instead. The file is available since kernel 4.1.
orig_data_size(first): uncompressed size of data stored in this disk.
compr_data_size(second): compressed size of data stored in this disk
mem_used_total(third): the amount of memory allocated for this disk
Also remove useless zram cleanup call in zram_fill_fs and so we don't
need to cleanup zram twice if fails.

Since commit 43209ea2d1 ("zram: remove max_comp_streams internals"), zram
has switched to per-cpu streams. Even kernel still keep this interface for
some reasons, but writing to max_comp_stream doesn't take any effect. So
skip it on newer kernel ie 4.7.
The code that comparing kernel version is from xfstests testsuite ext4/053.

We have some many cases that will create child process as well, such as
pidfd_wait. Previously, we will signal/kill the parent process when it
is time out, but this signal will not be sent to its child process. In
such case, if child process doesn't terminate itself, ksefltest framework
will hang forever.
Here we group all its child processes so that kill() can signal all of
them in timeout.

Use 'tee' to send the test output to stdout in addition to the current
output file. This makes the output easier to handle in automated test
systems and is superior to only later dumping the output file contents
to stdout, since this way the test output can be interleaved with other
log messages, like from the kernel, so that chronology is preserved,
making it easier to detect issues.

The timeout setting for the rtc kselftest is currently 90 seconds. This
setting is used by the kselftest runner to stop running a test if it
takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are
set to the next beginning of the minute, so each of these test cases may
take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst
case, when using the kselftest runner, the timeout value should be
increased to at least 120. Set it to 180, so there's some additional
slack.
Correct operation can be tested by running the following command right
after the start of a minute (low second count), and checking that all
test cases run:
./run_kselftest.sh -c rtc

As the sched:sched_switch tracepoint args are derived from the kernel,
we'd better make it same with the kernel. So the macro TASK_COMM_LEN is
converted to type enum, then all the BPF programs can get it through
BTF.
The BPF program which wants to use TASK_COMM_LEN should include the
header vmlinux.h. Regarding the test_stacktrace_map and
test_tracepoint, as the type defined in linux/bpf.h are also defined in
vmlinux.h, so we don't need to include linux/bpf.h again.

Add a VMX specific test to verify that KVM doesn't explode if userspace
attempts KVM_RUN when emulation is required with a pending exception.
KVM VMX's emulation support for !unrestricted_guest punts exceptions to
userspace instead of attempting to synthesize the exception with all the
correct state (and stack switching, etc...).
Punting is acceptable as there's never been a request to support
injecting exceptions when emulating due to invalid state, but KVM has
historically assumed that userspace will do the right thing and either
clear the exception or kill the guest. Deliberately do the opposite and
attempt to re-enter the guest with a pending exception and emulation
required to verify KVM continues to punt the combination to userspace,
e.g. doesn't explode, WARN, etc...

hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.
To make hmm_range_fault() more closely match get_user_pages() remove
this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte(). Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.
Also add a test to hmm selftest to verify functionality.

The message for commit f5c7329718 ("userfaultfd/selftests: fix hugetlb
area allocations") says there is no need to create a hugetlb file in the
non-shared testing case. However, the commit did not actually change
the code to prevent creation of the file.
While it is technically true that there is no need to create and use a
hugetlb file in the case of non-shared-testing, it is useful. This is
because 'hole punching' of a hugetlb file has the potentially incorrect
side effect of also removing pages from private mappings. The
userfaultfd test relies on this side effect for removing pages from the
destination buffer during rounds of stress testing.
Remove the incomplete code that was added to deal with no hugetlb file.
Just keep the code that prevents reserves from being created for the
destination area.

The hugetlb cgroup reservation test charge_reserved_hugetlb.sh assume
that no cgroup filesystems are mounted before running the test. That is
not true in many cases. As a result, the test fails to run. Fix that
by querying the current cgroup mount setting and using the existing
cgroup setup instead before attempting to freshly mount a cgroup
filesystem.
Similar change is also made for hugetlb_reparenting_test.sh as well,
though it still has problem if cgroup v2 isn't used.
The patched test scripts were run on a centos 8 based system to verify
that they ran properly.

The hugetlb vma mremap() test currently maps 1GB of memory to trigger
pmd sharing and make sure that 'unshare' path in mremap code works. The
test originally only mapped 10MB of memory (as specified by the header
comment) but was later modified to 1GB to tackle this case.
However, not all machines will have 1GB of memory to spare for this
test. Adding a mapping size arg will allow run_vmtest.sh to pass an
adequate mapping size, while allowing users to run the test
independently with arbitrary size mappings.

This selftest covers two aspects of AMX. The first is triggering #NM
exception and checking the MSR XFD_ERR value. The second case is
loading tile config and tile data into guest registers and trapping to
the host side for a complete save/load of the guest state. TMM0
is also checked against memory data after save/restore.

For AMX support it is recommended to load XCR0 after XFD, so
that KVM does not see XFD=0, XCR=1 for a save state that will
eventually be disabled (which would lead to premature allocation
of the space required for that save state).
It is also required to load XSAVE data after XCR0 and XFD, so
that KVM can trigger allocation of the extra space required to
store AMX state.
Adjust vcpu_load_state to obey these new requirements.

It's a relatively calm development cycle, but still lots of updates in
the driver side like Intel SOF. Below are some highlights:
* ALSA / ASoC core:
- A new kselftest for ALSA control API
- PCM NO_REWINDS support
- Potential race fixes around control removals
- Unify x86 SG-buffer memory allocation code
- Cleanups and race fixes for ASoC DPCM locking
* ASoC:
- Refinements and cleanups around the delay() APIs
- Wider use of dev_err_probe().
- Continuing cleanups and improvements to the SOF code
- Support for pin switches in simple-card derived cards
- Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
TLV320ADC3xxx
* HD-audio / USB-audio:
- Fix deadlock at HD-audio codec unbinding
- Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
- Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
* Misc:
- Fix virmidi drain behavior
Note that the merge of CS35L41 codec support is still half-baked, and
at least one ACPI change is missing. Although this won't hinder the
kernel build itself, we're going to catch up before RC1.

timeout in settings is used by each case under the same directory, so
it should adapt to the maximum runtime.
A normally running net/fib_nexthops.sh may be killed by this unsuitable
timeout. Furthermore, since the defect[1] of kselftests framework,
net/fib_nexthops.sh which might take at least (300 * 4) seconds would
block the whole kselftests framework previously.
$ git grep -w 'sleep 300' tools/testing/selftests/net
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
Enlarge the timeout by plus 300 based on the obvious largest runtime
to avoid the blocking.

Pull integrity subsystem updates from Mimi Zohar:
"The few changes are all kexec related:
- The MOK keys are loaded onto the .platform keyring in order to
verify the kexec kernel image signature.
However, the MOK keys should only be trusted when secure boot is
enabled. Before loading the MOK keys onto the .platform keyring,
make sure the system is booted in secure boot mode.
- When carrying the IMA measurement list across kexec, limit dumping
the measurement list to when dynamic debug or CONFIG_DEBUG is
enabled.
- kselftest: add kexec_file_load selftest support for PowerNV and
other cleanup"

Merge tag 'gpio-updates-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"The gpio-sim module is back, this time without any changes to
configfs. This results in a less elegant user-space interface but I
never got any follow-up on the committable items and didn't want to
delay this module for several more months.
Other than that we have support for several new models and some
support going away. We started working on converting GPIO drivers to
using fwnode exclusively in order to limit references to OF symbols to
gpiolib-of.c exclusively. We also have regular tweaks and improvements
all over the place.
Summary:
- new testing module: gpio-sim that is scheduled to replace
gpio-mockup
- initial changes aiming at converting all GPIO drivers to using the
fwnode interface and limiting any references to OF symbols to
gpiolib-of.c
- add support for Tegra234 and Tegra241 to gpio-tegra186
- add support for new models (SSD201 and SSD202D) to gpio-msc313
- add basic support for interrupts to gpio-aggregator
