There might be a condition where the fte found is not active yet. In
this case we should not use it, but continue to search for another, or
allocate a new one.

This fixes booting with the combination of CONFIG_RELOCATABLE=y
and CONFIG_MIPS_ELF_APPENDED_DTB=y.
Sections that appear after the relocation table are not relocated
on system boot (except .bss, which has special handling).
With CONFIG_MIPS_ELF_APPENDED_DTB, the dtb is part of the
vmlinux ELF, so it must be relocated together with everything else.

Timekeeping IRQs from CS5536 MFGPT are routed to i8259, which then
triggers the "cascade" IRQ on MIPS CPU. Without IRQF_NO_SUSPEND in
cascade_irqaction, MFGPT interrupts will be masked in suspend mode,
and the machine would be unable to resume once suspended.
Previously, MIPS IRQs were not disabled properly, so the original
code appeared to work. Commit a3e6c1eff5 ("MIPS: IRQ: Fix disable_irq on
CPU IRQs") uncovers the bug. To fix it, add IRQF_NO_SUSPEND to
cascade_irqaction.
This commit is functionally identical to 0add9c2f1cff ("MIPS:
Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction"), but it forgot
to apply the same fix to Loongson2.

Referencing the __kernel_long_t type caused some user space applications
to stop compiling when they had not already included linux/posix_types.h,
e.g.
s/multicast.c -o ext/sockets/multicast.lo
In file included from /builddir/build/BUILD/php-7.3.3/main/php.h:468,
from /builddir/build/BUILD/php-7.3.3/ext/sockets/sockets.c:27:

776 | REGISTER_LONG_CONSTANT("SO_SNDTIMEO", SO_SNDTIMEO, CONST_CS | CONST_PERSISTENT);
It is safe to include that header here, since it only contains kernel
internal types that do not conflict with other user space types.
It's still possible that some related build failures remain, but those
are likely to be for code that is not already y2038 safe.

Several of these scripts have come in as old-fashioned patches, and in
the process lost the executable bit. In most cases it doesn't matter,
since the test infrastructure will explicitly execute them using the
proper shell interpreter, but at least in the case of the new vmalloc
test, the lack of execurable bit caused the test to fail with
./run_vmtests: line 217: ./test_vmalloc.sh: Permission denied
because of the lacking exectuable permissions bit.
This patch fixes that up.
NOTE! A simple script to look for non-executable scripts in the kernel,
something like
git ls-files --stage -- '*.sh' |
grep 100644 |
cut -f2 |
xargs grep -l '#!'
will show that there's a lot of other files that _look_ like executable
shell scripts, but don't have the executable bit set. I considered just
scripting them all to be executable, but since it looks like the common
pattern is to not really require it, I'm just doing the minimal fix as
pointed out by the kernel test robot.

The UI viewer for scripts output has a lot of limitations: limited size,
no search or save function, slow, and various other issues.

This won't work in GTK mode, but GTK doesn't support these context menus
anyways. If that is ever done could use an terminal for the output.

The data files layout is described by HEADER_DIR_FORMAT feature.
Currently it holds only version number (1):
uint64_t version;
The current version holds only version value (1) means that data files:
- Follow the 'data.*' name format.
- Contain raw events data in standard perf format as read from kernel
(and need to be sorted)
Future versions are expected to describe different data files layout
according to special needs.

perf script -F +insn was only working for PT traces because the PT
instruction decoder was filling in the insn/insn_len sample attributes.
Support it for non PT samples too on x86 using the existing x86
instruction decoder.
This adds some extra checking to ensure that we don't try to decode
instructions when using perf.data from a different architecture.

On mmap(), perf_events generates a RECORD_MMAP record and then checks
which events are interested in this record. There are currently 2
versions of mmap records: RECORD_MMAP and RECORD_MMAP2. MMAP2 is larger.
The event configuration controls which version the user level tool
accepts.
If the event->attr.mmap2=1 field then MMAP2 record is returned. The
perf_event_mmap_output() takes care of this. It checks attr->mmap2 and
corrects the record fields before putting it in the sampling buffer of
the event. At the end the function restores the modified MMAP record
fields.
The problem is that the function restores the size but not the type.
Thus, if a subsequent event only accepts MMAP type, then it would
instead receive an MMAP2 record with a size of MMAP record.
This patch fixes the problem by restoring the record type on exit.

We seem to rely on the number of phandles specified in the
'required-opps' property to identify cases where a device is
associated with multiple power domains and hence would have
multiple virtual devices that have to be dealt with.
In cases where we do have devices with multiple power domains
but with only one of them being scalable, this logic seems to
fail.
Instead read the number of power domains from DT to identify
such cases.

Previously, if BTF data was parsed successfully, but failed to load into

cleanup and warning reporting.

During noirq suspend phase, mailbox MU irq will be masked
but many drivers still need to communicate with system
controller firmware via mailbox, if MU irq is masked, it
will cause RPC timeout as below:
[ 23.372103] imx-scu scu: RPC send msg timeout
Setting MU irq to be wakeup source is NOT working as GIC
driver does NOT have .irq_set_wake implemented, so to
support suspend/resume, just make imx mailbox driver NOT
suspend, since MU is always a wakeup source on i.MX platforms
with system controller inside, and its power/clock is
maintained by system controller, mailbox driver no need

Pull tpm updates from James Morris:
- Clean up the transmission flow
Cleaned up the whole transmission flow. Locking of the chip is now
done in the level of tpm_try_get_ops() and tpm_put_ops() instead
taking the chip lock inside tpm_transmit(). The nested calls inside
tpm_transmit(), used with the resource manager, have been refactored
out.
Should make easier to perform more complex transactions with the TPM
without making the subsystem a bigger mess (e.g. encrypted channel
patches by James Bottomley).
- PPI 1.3 support
TPM PPI 1.3 introduces an additional optional command parameter that
may be needed for some commands. Display the parameter if the command
requires such a parameter. Only command 23 (SetPCRBanks) needs one.
The PPI request file will show output like this then:
# echo "23 16" > request
# cat request
23 16
# echo "5" > request
# cat request
5
- Extend all PCR banks in IMA
Instead of static PCR banks array, the array of available PCR banks
is now allocated dynamically. The digests sizes are determined
dynamically using a probe PCR read without relying crypto's static
list of hash algorithms.
This should finally make sealing of measurements in IMA safe and
secure.
- TPM 2.0 selftests
