Fix several typos and grammatical errors in the Bounded type documentation:
- "less significant bits" -> "least significant bits"
- "with in" -> "within"
- "withheld" -> "upheld"
- "// This" -> "// This" (double space)
- "doesn't fits" -> "doesn't fit" (2 occurrences)

Change `page_align()` to return `Option<usize>` to allow validation
of the provided `addr` value. This ensures that any value that is
within one `PAGE_SIZE` of `usize::MAX` will not panic, and instead
returns `None` to indicate overflow.

This is because the destructor of maple tree calls mas_find() without
taking rcu_read_lock() or the spinlock. Doing that is actually ok in this
case since the destructor has exclusive access to the entire maple tree,
but it triggers a lockdep warning. To fix that, take the rcu read lock.
In the future, it's possible that memory reclaim could gain a feature
where it reallocates entries in maple trees even if no user-code is
touching it. If that feature is added, then this use of rcu read lock
would become load-bearing, so I did not make it conditional on lockdep.
We have to repeatedly take and release rcu because the destructor of T
might perform operations that sleep.

Add dma_set_mask(), dma_set_coherent_mask(), dma_map_sgtable(), and
dma_max_mapping_size() helpers to fix a build error when
CONFIG_HAS_DMA is not enabled.
Note that when CONFIG_HAS_DMA is enabled, they are included in both

takes precedence so behavior remains unchanged in that case.

Orchestrator (LUO), and possibly for other future clients
- "kho: simplify state machine and enable dynamic updates" (Pasha Tatashin)
increases the flexibility of KEXEC Handover. Also preparation for LUO
- "Live Update Orchestrator" (Pasha Tatashin)
is a major new feature targeted at cloud environments. Quoting the
cover letter:
This series introduces the Live Update Orchestrator, a kernel
subsystem designed to facilitate live kernel updates using a
kexec-based reboot. This capability is critical for cloud
environments, allowing hypervisors to be updated with minimal
downtime for running virtual machines. LUO achieves this by
preserving the state of selected resources, such as memory,
devices and their dependencies, across the kernel transition.
As a key feature, this series includes support for preserving
memfd file descriptors, which allows critical in-memory data, such
as guest RAM or any other large memory region, to be maintained in
RAM across the kexec reboot.
Mike Rappaport merits a mention here, for his extensive review and
testing work.
- "kexec: reorganize kexec and kdump sysfs" (Sourabh Jain)
moves the kexec and kdump sysfs entries from /sys/kernel/ to
/sys/kernel/kexec/ and adds back-compatibility symlinks which can

Commit 14e9a18b07ec ("rust: sync: atomic: Make Atomic*Ops pub(crate)")
added a `pub(crate)` import in the same "block" as the `pub` one,
without running `rustfmt`, which would sort them differently.
Instead of running `rustfmt` as-is, add a newline to keep the import
"blocks" with different visibilities separate.

Pull module updates from Daniel Gomez:
"Rust module parameter support:
- Add Rust module parameter support, enabling Rust kernel modules to
declare and use module parameters. The rust_minimal sample module
demonstrates this, and the rust null block driver will be the first
to use it in the next cycle. This also adds the Rust module files
under the modules subsystem as agreed between the Rust and modules
maintainers.
Hardening:
- Add compile-time check for embedded NUL characters in MODULE_*()
macros. This module metadata was once used (and maybe still) to
bypass license enforcement (LWN article from 2003):
