Pull arm64 fixes from Will Deacon:
"Ryan's been hard at work finding and fixing mm bugs in the arm64 code,
so here's a small crop of fixes for -rc5.
The main changes are to fix our zapping of non-present PTEs for
hugetlb entries created using the contiguous bit in the page-table
rather than a block entry at the level above. Prior to these fixes, we
were pulling the contiguous bit back out of the PTE in order to
determine the size of the hugetlb page but this is clearly bogus if
the thing isn't present and consequently both the clearing of the
PTE(s) and the TLB invalidation were unreliable.
Although the problem was found by code inspection, we really don't
want this sitting around waiting to trigger and the changes are CC'd
to stable accordingly.
Note that the diffstat looks a lot worse than it really is;
huge_ptep_get_and_clear() now takes a size argument from the core code
and so all the arch implementations of that have been updated in a
pretty mechanical fashion.

kvm: retry nx_huge_page_recovery_thread creation
A VMM may send a non-fatal signal to its threads, including vCPU tasks, at any time, and thus may signal vCPU tasks during KVM_RUN. If a vCPU task receives the signal while its trying to spawn the huge page recovery vhost task, then KVM_RUN will fail due to copy_process() returning -ERESTARTNOINTR. Rework call_once() to mark the call complete if and only if the called function succeeds, and plumb the function's true error code back to the call_once() invoker. This provides userspace with the correct, non-fatal error code so that the VMM doesn't terminate the VM on -ENOMEM, and allows subsequent KVM_RUN a succeed by virtue of retrying creation of the NX huge page task.

Tracing fixes for v6.14:
- Fix crash from bad histogram entry
An error path in the histogram creation could leave an entry
in a link list that gets freed. Then when a new entry is added
it can cause a u-a-f bug. This is fixed by restructuring the code
so that the histogram is consistent on failure and everything is
cleaned up appropriately.
- Fix fprobe self test
The fprobe self test relies on no function being attached by ftrace.
BPF programs can attach to functions via ftrace and systemd now
does so. This causes those functions to appear in the enabled_functions
list which holds all functions attached by ftrace. The selftest also
uses that file to see if functions are being connected correctly.
It counts the functions in the file, but if there's already functions
in the file, it fails. Instead, add the number of functions in the file
at the start of the test to all the calculations during the test.
- Fix potential division by zero of the function profiler stddev
The calculated divisor that calculates the standard deviation of
the function times can overflow. If the overflow happens to land
on zero, that can cause a division by zero. Check for zero from
the calculation before doing the division.
TODO: Catch when it ever overflows and report it accordingly.
For now, just prevent the system from crashing.

intel_idle: Handle older CPUs, which stop the TSC in deeper C states, correctly
The Intel idle driver is preferred over the ACPI processor idle driver,
but fails to implement the work around for Core2 generation CPUs, where
the TSC stops in C2 and deeper C-states. This causes stalls and boot
delays, when the clocksource watchdog does not catch the unstable TSC
before the CPU goes deep idle for the first time.
The ACPI driver marks the TSC unstable when it detects that the CPU
supports C2 or deeper and the CPU does not have a non-stop TSC.
Add the equivivalent work around to the Intel idle driver to cure that.

Merge tag 'efi-fixes-for-v6.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI fixes from Ard Biesheuvel:
"Another couple of EFI fixes for v6.14.
Only James's patch stands out, as it implements a workaround for odd
behavior in fwupd in user space, which creates EFI variables by
touching a file in efivarfs, clearing the immutable bit (which gets
set automatically for $reasons) and then opening it again for writing,
none of which is really necessary.
The fwupd author and LVFS maintainer is already rolling out a fix for
this on the fwupd side, and suggested that the workaround in this PR
could be backed out again during the next cycle.
(There is a semantic mismatch in efivarfs where some essential
variable attributes are stored in the first 4 bytes of the file, and
so zero length files cannot exist, as they cannot be written back to
the underlying variable store. So now, they are dropped once the last
reference is released.)

- Fix CPER error record parsing bugs
- Fix a couple of efivarfs issues that were introduced in the merge

- Fix an issue in the early remapping code of the MOKvar table"

gpiolib: Fix Oops in gpiod_direction_input_nonotify()
The gpiod_direction_input_nonotify() function is supposed to return zero
if the direction for the pin is input. But instead it accidentally
returns GPIO_LINE_DIRECTION_IN (1) which will be cast into an ERR_PTR()
in gpiochip_request_own_desc(). The callers dereference it and it leads
to a crash.
I changed gpiod_direction_output_raw_commit() just for consistency but
returning GPIO_LINE_DIRECTION_OUT (0) is fine.

iommu/vt-d: Remove device comparison in context_setup_pass_through_cb
Remove the device comparison check in context_setup_pass_through_cb.
pci_for_each_dma_alias already makes a decision on whether the
callback function should be called for a device. With the check
in place it will fail to create context entries for aliases as
it walks up to the root bus.

iommu/amd: Preserve default DTE fields when updating Host Page Table Root
When updating the page table root field on the DTE, avoid overwriting any
bits that are already set. The earlier call to make_clear_dte() writes
default values that all DTEs must have set (currently DTE[V]), and those
must be preserved.
Currently this doesn't cause problems since the page table root update is
the first field that is set after make_clear_dte() is called, and
DTE_FLAG_V is set again later along with the permission bits (IR/IW).
Remove this redundant assignment too.

Check whether denominator expression x * (x - 1) * 1000 mod {2^32, 2^64}
produce zero and skip stddev computation in that case.

selftests/ftrace: Let fprobe test consider already enabled functions
The fprobe test fails on Fedora 41 since the fprobe test assumption that
the number of enabled_functions is zero before the test starts is not
necessarily true. Some user space tools, like systemd, add BPF programs
that attach to functions. Those will show up in the enabled_functions table
and must be taken into account by the fprobe test.
Therefore count the number of lines of enabled_functions before tests
start, and use that as base when comparing expected results.

tracing: Fix bad hist from corrupting named_triggers list
The following commands causes a crash:
~# cd /sys/kernel/tracing/events/rcu/rcu_callback
~# echo 'hist:name=bad:keys=common_pid:onmax(bogus).save(common_pid)' > trigger
bash: echo: write error: Invalid argument
~# echo 'hist:name=bad:keys=common_pid' > trigger
Because the following occurs:
event_trigger_write() {
trigger_process_regex() {
event_hist_trigger_parse() {
data = event_trigger_alloc(..);
event_trigger_register(.., data) {
cmd_ops->reg(.., data, ..) [hist_register_trigger()] {
data->ops->init() [event_hist_trigger_init()] {
save_named_trigger(name, data) {
list_add(&data->named_list, &named_triggers);
}
}
}
}
ret = create_actions(); (return -EINVAL)
if (ret)
goto out_unreg;
[..]
ret = hist_trigger_enable(data, ...) {
list_add_tail_rcu(&data->list, &file->triggers); <<<---- SKIPPED!!! (this is important!)
[..]
out_unreg:
event_hist_unregister(.., data) {
cmd_ops->unreg(.., data, ..) [hist_unregister_trigger()] {
list_for_each_entry(iter, &file->triggers, list) {
if (!hist_trigger_match(data, iter, named_data, false)) <- never matches
continue;
[..]
test = iter;
}
if (test && test->ops->free) <<<-- test is NULL
test->ops->free(test) [event_hist_trigger_free()] {
[..]
if (data->name)
del_named_trigger(data) {
list_del(&data->named_list); <<<<-- NEVER gets removed!
}
}
}
}
[..]
kfree(data); <<<-- frees item but it is still on list
The next time a hist with name is registered, it causes an u-a-f bug and
the kernel can crash.
Move the code around such that if event_trigger_register() succeeds, the
next thing called is hist_trigger_enable() which adds it to the list.
A bunch of actions is called if get_named_trigger_data() returns false.
But that doesn't need to be called after event_trigger_register(), so it
can be moved up, allowing event_trigger_register() to be called just
before hist_trigger_enable() keeping them together and allowing the
file->triggers to be properly populated.

A later callback in the resume path invoked cond_resched() which in turn led to the invocation of the scheduler: __cond_resched+0x21/0x60 down_timeout+0x18/0x60 acpi_os_wait_semaphore+0x4c/0x80 acpi_ut_acquire_mutex+0x3d/0x100 acpi_ns_get_node+0x27/0x60 acpi_ns_evaluate+0x1cb/0x2d0 acpi_rs_set_srs_method_data+0x156/0x190 acpi_pci_link_set+0x11c/0x290 irqrouter_resume+0x54/0x60 syscore_resume+0x6a/0x200 kernel_kexec+0x145/0x1c0 __do_sys_reboot+0xeb/0x240 do_syscall_64+0x95/0x180 This is a long standing problem, which probably got more visible with the recent printk changes. Something does a task wakeup and the scheduler sets the NEED_RESCHED flag. cond_resched() sees it set and invokes schedule() from a completely bogus context. The scheduler enables interrupts after context switching, which causes the above warning at the end. Quite some of the code paths in syscore_suspend()/resume() can result in triggering a wakeup with the exactly same consequences. They might not have done so yet, but as they share a lot of code with normal operations it's just a question of time. The problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY scheduling models. Full preemption is not affected as cond_resched() is disabled and the preemption check preemptible() takes the interrupt disabled flag into account. Cure the problem by adding a corresponding check into cond_resched().

arm64: hugetlb: Fix flush_hugetlb_tlb_range() invalidation level

arm64: hugetlb: Fix huge_ptep_get_and_clear() for non-present ptes
arm64 supports multiple huge_pte sizes. Some of the sizes are covered by
a single pte entry at a particular level (PMD_SIZE, PUD_SIZE), and some
are covered by multiple ptes at a particular level (CONT_PTE_SIZE,
CONT_PMD_SIZE). So the function has to figure out the size from the
huge_pte pointer. This was previously done by walking the pgtable to
determine the level and by using the PTE_CONT bit to determine the
number of ptes at the level.
But the PTE_CONT bit is only valid when the pte is present. For
non-present pte values (e.g. markers, migration entries), the previous
implementation was therefore erroneously determining the size. There is
at least one known caller in core-mm, move_huge_pte(), which may call
huge_ptep_get_and_clear() for a non-present pte. So we must be robust to
this case. Additionally the "regular" ptep_get_and_clear() is robust to
being called for non-present ptes so it makes sense to follow the
behavior.
Fix this by using the new sz parameter which is now provided to the
function. Additionally when clearing each pte in a contig range, don't
gather the access and dirty bits if the pte is not present.
An alternative approach that would not require API changes would be to
store the PTE_CONT bit in a spare bit in the swap entry pte for the
non-present case. But it felt cleaner to follow other APIs' lead and
just pass in the size.
As an aside, PTE_CONT is bit 52, which corresponds to bit 40 in the swap
entry offset field (layout of non-present pte). Since hugetlb is never
swapped to disk, this field will only be populated for markers, which
always set this bit to 0 and hwpoison swap entries, which set the offset
field to a PFN; So it would only ever be 1 for a 52-bit PVA system where
memory in that high half was poisoned (I think!). So in practice, this
bit would almost always be zero for non-present ptes and we would only
clear the first entry if it was actually a contiguous block. That's
probably a less severe symptom than if it was always interpreted as 1
and cleared out potentially-present neighboring PTEs.

mm: hugetlb: Add huge page size param to huge_ptep_get_and_clear()
In order to fix a bug, arm64 needs to be told the size of the huge page
for which the huge_pte is being cleared in huge_ptep_get_and_clear().
Provide for this by adding an `unsigned long sz` parameter to the
function. This follows the same pattern as huge_pte_clear() and
set_huge_pte_at().
This commit makes the required interface modifications to the core mm as
well as all arches that implement this function (arm64, loongarch, mips,
parisc, powerpc, riscv, s390, sparc). The actual arm64 bug will be fixed
in a separate commit.
