Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"

In the pmtu_vti6_link_change_mtu test, both local and remote addresses
for the vti6 tunnel are assigned to the same address given to the dummy
interface that we use as encapsulating device with a known MTU.
This works as long as the dummy interface is actually selected, via
rt6_lookup(), as encapsulating device. But if the remote address of the
tunnel is a local address too, the loopback interface could also be
selected, and there's nothing wrong with it.
This is what some older -stable kernels do (3.18.z, at least), and
nothing prevents us from subtly changing FIB implementation to revert
back to that behaviour in the future.
Define an IPv6 prefix instead, and use two separate addresses as local
and remote for vti6, so that the encapsulating device can't be a
loopback interface.

None entails changes in tooling, the closest to that were some new arch
specific ioctls, that are still not handled by the tools/perf/trace/beauty/
library, that needs to create per-arch tables to convert ioctl cmd->string (and
back).
From a quick look the arch specific kvm-stat.c files at:
$ ls -1 tools/perf/arch/*/util/kvm-stat.c
tools/perf/arch/powerpc/util/kvm-stat.c
tools/perf/arch/s390/util/kvm-stat.c
tools/perf/arch/x86/util/kvm-stat.c
$
Are not affected.
This silences these perf building warnings:

Command 'perf record' and 'perf report' on a system without kernel
debuginfo packages uses /proc/kallsyms and /proc/modules to find
addresses for kernel and module symbols. On x86 this works for root and
non-root users.
On s390, when invoked as non-root user, many of the following warnings
are shown and module symbols are missing:
proc/{kallsyms,modules} inconsistency while looking for
"[sha1_s390]" module!
Command 'perf record' creates a list of module start addresses by
parsing the output of /proc/modules and creates a PERF_RECORD_MMAP
record for the kernel and each module. The following function call
sequence is executed:
machine__create_kernel_maps
machine__create_module
modules__parse
machine__create_module --> for each line in /proc/modules
arch__fix_module_text_start
Function arch__fix_module_text_start() is s390 specific. It opens
file /sys/module/<name>/sections/.text to extract the module's .text
section start address. On s390 the module loader prepends a header
before the first section, whereas on x86 the module's text section
address is identical the the module's load address.
However module section files are root readable only. For non-root the
read operation fails and machine__create_module() returns an error.
Command perf record does not generate any PERF_RECORD_MMAP record
for loaded modules. Later command perf report complains about missing
module maps.
To fix this function arch__fix_module_text_start() always returns
success. For root users there is no change, for non-root users
the module's load address is used as module's text start address
(the prepended header then counts as part of the text section).
This enable non-root users to use module symbols and avoid the
warning when perf report is executed.
Output before:
[tmricht@m83lp54 perf]$ ./perf report -D | fgrep MMAP
0 0x168 [0x50]: PERF_RECORD_MMAP ... x [kernel.kallsyms]_text

No need to search for aliases for the symbol that marks the end of the
kernel text segment, the following patch will make such symbols not to
be found when searching in the kallsyms maps causing this test to fail.
So as a prep patch to avoid breaking bisection, ignore such symbols.

I.e. the strace like raw_tracepoint:sys_enter handler in 'perf trace'
will get the cmd integer value and map it to the string.
At some point it should be possible to translate from string to integer
and use to filter using expressions such as:
# perf trace -e ioctl/cmd==DRM_IOCTL_SYNCOBJ*/
Or some more suitable syntax to express that only these ioctls when
acting on DRM fds should be shown.

When a host system has kernel headers that are newer than a compiling
kernel, mksyscalltbl fails with errors such as:
<stdin>: In function 'main':
<stdin>:271:44: error: '__NR_kexec_file_load' undeclared (first use in this function)

tools/perf/arch/arm64/entry/syscalls//mksyscalltbl: line 48: /tmp/create-table-xvUQdD: Permission denied
mksyscalltbl is compiled with default host includes, but run with
compiling kernel tree includes, causing some syscall numbers to being
undeclared.
Committer testing:
Before this patch, in my cross build environment, no build problems, but
these new syscalls were not in the syscalls.c generated from the
unistd.h file, which is a bug, this patch fixes it:
perfbuilder@6e20056ed532:/git/perf$ tail /tmp/build/perf/arch/arm64/include/generated/asm/syscalls.c
[292] = "io_pgetevents",
[293] = "rseq",
[294] = "kexec_file_load",
[424] = "pidfd_send_signal",
[425] = "io_uring_setup",
[426] = "io_uring_enter",
[427] = "io_uring_register",
[428] = "syscalls",
};
perfbuilder@6e20056ed532:/git/perf$ strings /tmp/build/perf/perf | egrep '^(io_uring_|pidfd_|kexec_file)'
kexec_file_load
pidfd_send_signal
io_uring_setup
io_uring_enter
io_uring_register
perfbuilder@6e20056ed532:/git/perf$
$
Well, there is that last "syscalls" thing, but that looks like some
other bug.

parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later".
Only the "obvious" versions of these matches are included here, a
number of "non-obvious" variants of text have been found but those
have been postponed for later review and analysis.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"

uie_read is a commonly failing test that will block forever on buggy rtc
drivers. Shorten its timeout so it fails earlier. Also increase the timeout
for the two alarm test on a minute boundary.

Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test")
adds an hardcoded 30s timeout to all tests. Unfortunately, rtctest has two
tests taking up to 60s. Allow for individual tests to define their own
timeout.

The fields filter would not work with child fields, as the respective
parents would not be included. No parents displayed == no childs displayed.
To reproduce, run on s390 (would work on other platforms, too, but would
require a different filter name):
- Run 'kvm_stat -d'
- Press 'f'
- Enter 'instruct'
Notice that events like instruction_diag_44 or instruction_diag_500 are not
displayed - the output remains empty.
With this patch, we will filter by matching events and their parents.
However, consider the following example where we filter by
instruction_diag_44:
kvm statistics - summary
regex filter: instruction_diag_44
Event Total %Total CurAvg/s
exit_instruction 276 100.0 12
instruction_diag_44 256 92.8 11
Total 276 12
Note that the parent ('exit_instruction') displays the total events, but
the childs listed do not match its total (256 instead of 276). This is
intended (since we're filtering all but one child), but might be confusing
on first sight.

to compile the code on other architectures as well, we need to wrap

VM_MODE_P52V48_4K is not a valid mode for AArch64. Replace its
use in vm_create_default() with a mode that works and represents
a good AArch64 default. (We didn't ever see a problem with this
because we don't have any unit tests using vm_create_default(),
but it's good to get it fixed in advance.)

The memory slot size must be aligned to the host's page size. When
testing a guest with a 4k page size on a host with a 64k page size,
then 3 guest pages are not host page size aligned. Since we just need
a nearly arbitrary number of extra pages to ensure the memslot is not
aligned to a 64 host-page boundary for this test, then we can use
16, as that's 64k aligned, but not 64 * 64k aligned.

The guest_code of sync_regs_test is assuming that the compiler will not
touch %r11 outside the asm that increments it, which is a bit brittle.
Instead, we can increment a variable and use a dummy asm to ensure the
increment is not optimized away. However, we also need to use a
callee-save register or the compiler will insert a save/restore around
the vmexit, breaking the whole idea behind the test.
(Yes, "if it ain't broken...", but I would like the test to be clean
before it is copied into the upcoming s390 selftests).

So far the KVM selftests are compiled without any compiler warnings
enabled. That's quite bad, since we miss a lot of possible bugs this
way. Let's enable at least "-Wall" and some other useful warning flags
now, and fix at least the trivial problems in the code (like unused
variables).
