commit 40fc3054b4 upstream.
Commit 628a5c5618 ("[INET]: Add IP(V6)_PMTUDISC_RPOBE") introduced
ip6_skb_dst_mtu with return value of signed int which is inconsistent
with actually returned values. Also 2 users of this function actually
assign its value to unsigned int variable and only __xfrm6_output
assigns result of this function to signed variable but actually uses
as unsigned in further comparisons and calls. Change this function
to return unsigned int value.

commit 5a3c680aa2 upstream.
Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection
logic of the internal PHY to prevent the system from sleeping. Some
internal PHYs will report that energy is detected when the network
interface is closed which can prevent the system from going to sleep
if WoL is enabled when the interface is brought down.
Since the driver does not support waking the system on this logic,
this commit clears the bit whenever the internal PHY is powered up
and the other logic for manipulating the bit is removed since it
serves no useful function.

commit 122e093c17 upstream.
On systems with memory nodes sorted in descending order, for instance Dell
Precision WorkStation T5500, the struct pages for higher PFNs and
respectively lower nodes, could be overwritten by the initialization of
struct pages corresponding to the holes in the memory sections.
For example for the below memory layout
[ 0.245624] Early memory node ranges
[ 0.248496] node 1: [mem 0x0000000000001000-0x0000000000090fff]
[ 0.251376] node 1: [mem 0x0000000000100000-0x00000000dbdf8fff]
[ 0.254256] node 1: [mem 0x0000000100000000-0x0000001423ffffff]
[ 0.257144] node 0: [mem 0x0000001424000000-0x0000002023ffffff]
the range 0x1424000000 - 0x1428000000 in the beginning of node 0 starts in
the middle of a section and will be considered as a hole during the
initialization of the last section in node 1.
The wrong initialization of the memory map causes panic on boot when
CONFIG_DEBUG_VM is enabled.
Reorder loop order of the memory map initialization so that the outer loop
will always iterate over populated memory regions in the ascending order
and the inner loop will select the zone corresponding to the PFN range.
This way initialization of the struct pages for the memory holes will be
always done for the ranges that are actually not populated.

commit 8f34f1eac3 upstream.
We tried to do something similar in b569a17607 ("userfaultfd: wp: drop
_PAGE_UFFD_WP properly when fork") previously, but it's not doing it all
right.. A few fixes around the code path:
1. We were referencing VM_UFFD_WP vm_flags on the _old_ vma rather
than the new vma. That's overlooked in b569a17607, so it won't work
as expected. Thanks to the recent rework on fork code
(7a4830c380), we can easily get the new vma now, so switch the
checks to that.
2. Dropping the uffd-wp bit in copy_huge_pmd() could be wrong if the
huge pmd is a migration huge pmd. When it happens, instead of using
pmd_uffd_wp(), we should use pmd_swp_uffd_wp(). The fix is simply to
handle them separately.
3. Forget to carry over uffd-wp bit for a write migration huge pmd
entry. This also happens in copy_huge_pmd(), where we converted a
write huge migration entry into a read one.
4. In copy_nonpresent_pte(), drop uffd-wp if necessary for swap ptes.
5. In copy_present_page() when COW is enforced when fork(), we also
need to pass over the uffd-wp bit if VM_UFFD_WP is armed on the new
vma, and when the pte to be copied has uffd-wp bit set.
Remove the comment in copy_present_pte() about this. It won't help a huge
lot to only comment there, but comment everywhere would be an overkill.
Let's assume the commit messages would help.

commit 5fc7a5f6fd upstream.
Patch series "mm/uffd: Misc fix for uffd-wp and one more test".
This series tries to fix some corner case bugs for uffd-wp on either thp
or fork(). Then it introduced a new test with pagemap/pageout.
Patch layout:
Patch 1: cleanup for THP, it'll slightly simplify the follow up patches
Patch 2-4: misc fixes for uffd-wp here and there; please refer to each patch
Patch 5: add pagemap support for uffd-wp
Patch 6: add pagemap/pageout test for uffd-wp
The last test introduced can also verify some of the fixes in previous
patches, as the test will fail without the fixes. However it's not easy
to verify all the changes in patch 2-4, but hopefully they can still be
properly reviewed.
Note that if considering the ongoing uffd-wp shmem & hugetlbfs work, patch
5 will be incomplete as it's missing e.g. hugetlbfs part or the special
swap pte detection. However that's not needed in this series, and since
that series is still during review, this series does not depend on that
one (the last test only runs with anonymous memory, not file-backed). So
this series can be merged even before that series.
This patch (of 6):
Huge zero page is handled in a special path in copy_huge_pmd(), however it
should share most codes with a normal thp page. Trying to share more code
with it by removing the special path. The only leftover so far is the
huge zero page refcounting (mm_get_huge_zero_page()), because that's
separately done with a global counter.
This prepares for a future patch to modify the huge pmd to be installed,
so that we don't need to duplicate it explicitly into huge zero page case
too.

Move the turris-mox-rwtm firmware node from Turris MOX' device tree into
the generic armada-37xx.dtsi file and use the generic compatible string
'marvell,armada-3700-rwtm-firmware' instead of the current one.
Turris MOX DTS file contains also old compatible string for backward
compatibility.
The Turris MOX rWTM firmware can be used on any Armada 37xx device,
giving them access to the rWTM hardware random number generator, which
is otherwise unavailable.
This change allows Linux to load the turris-mox-rwtm.ko module on these
boards.
Tested on ESPRESSObin v5 with both default Marvell WTMI firmware and
CZ.NIC's firmware. With default WTMI firmware the turris-mox-rwtm fails
to probe, while with CZ.NIC's firmware it registers the HW random number
generator.

[ Upstream commit 41d71fe59c ]
The existing CALL_ON_STACK() macro allows for subtle bugs:
- There is no type checking of the function that is being called. That
is: missing or too many arguments do not cause any compile error or
warning. The same is true if the return type of the called function
changes. This can lead to quite random bugs.
- Sign and zero extension of arguments is missing. Given that the s390
C ABI requires that the caller of a function performs proper sign
and zero extension this can also lead to subtle bugs.
- If arguments to the CALL_ON_STACK() macros contain functions calls
register corruption can happen due to register asm constructs being
used.
Therefore introduce a new call_on_stack() macro which is supposed to
fix all these problems.

This does not cause user-facing issues or errors; other than

[ Upstream commit 742b0d7e15 ]
Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

To avoid unnecessary recompilations, mkcompile_h does not regenerate
compile.h if just the timestamp changed.
Though, if KBUILD_BUILD_TIMESTAMP is set, an explicit timestamp for the
build was requested, in which case we should not ignore it.
If a user follows the documentation for reproducible builds [1] and
defines KBUILD_BUILD_TIMESTAMP as the git commit timestamp, a clean
build will have the correct timestamp. A subsequent cherry-pick (or
amend) changes the commit timestamp and if an incremental build is done
with a different KBUILD_BUILD_TIMESTAMP now, that new value is not taken
into consideration. But it should for reproducibility.
Hence, whenever KBUILD_BUILD_TIMESTAMP is explicitly set, do not ignore
UTS_VERSION when making a decision about whether the regenerated version
of compile.h should be moved into place.

This fixes multiple issues with the current non-existent PCIe clock setup:
The controller can run at up to 250MHz, so use a parent that provides this
clock.
The PHY needs an exact 100MHz reference clock to function if the PCIe
refclock is not fed in via the refclock pads. While this mode is not
supported (yet) in the driver it doesn't hurt to make sure we are
providing a clock with the right rate.
The AUX clock is specified to have a maximum clock rate of 10MHz. So
the current setup, which drives it straight from the 25MHz oscillator is
actually overclocking the AUX input.

[ Upstream commit 093a474ce1 ]
If the PM related modules are not loaded and PM firmware not configured,
the system suspend fails to resume. Let's fix this by adding initial
platform_suspend_ops to block suspend and warn about missing modules.
When pm33xx and wkup_m3_ipc have been loaded and m3 coprocessor booted
with it's firmware, pm33xx sets up working platform_suspend_ops. Note
that we need to configure at least PM_SUSPEND_STANDBY to have
suspend_set_ops().

[ Upstream commit 4bf4abe190 ]
On some STM32 MP15 boards, stpmic node is not correct which generates
warnings running "make dtbs_check W=1" command. Issues are:
-"regulator-active-discharge" is not a boolean but an uint32.
-"regulator-over-current-protection" is not a valid entry for vref_ddr.
-LDO4 has a fixed voltage (3v3) so min/max entries are not allowed.

[ Upstream commit f493162319 ]
The Seeed SoM-STM32MP157C device tree had the eMMC’s (SDMMC2) VQMMC
supply set to v3v3 (buck4), the same as the VMMC supply. That was
incorrect, as on the SoM, the VQMMC supply is provided from vdd (buck3)
instead.
