The internal implementation of `file_mq_receive` did not allow
receiving a message from an interrupt handler. Although it is not
possible to wait for a message in an interrupt context, it is
perfectly possible to retrieve already-existing messages from the
message queue. This commit modifies file_mq_timedreceive_internal
to enable checking the message list and, if no messages exist, it
returns immediately. This enables receiving any existing messages
in an interrupt context.

Fix three issues in the STM32H7 FDCAN SocketCAN driver:
1. Clock configuration: Allow board.h to override STM32_FDCANCLK.
Previously the driver hardcoded STM32_HSE_FREQUENCY, ignoring
any board-specific clock configuration.
2. ILS register bug: Fix putreg32 call that was writing FDCAN_ILS_TCL
constant instead of the computed regval, causing interrupt routing
issues.
3. Extended ID filter size: Increase n_extid from 64 to 128. Despite
the reference manual (RM0433) suggesting 64 max, testing shows
that 128 is required for reliable extended ID frame reception.
With 64, some extended ID frames were silently dropped.

In file_dup3, the file descriptor is initialized with the O_NONBLOCK flag.
If the inode's ioctl(FIONBIO) call fails with a result other than OK or
ENOTTY, the file may be mistakenly released.

- Add support for the MR-NAVQ95 which is an open-source development
board designed for mobile robotics applications.
- Utilizes the NXP i.MX95 processor M7 core
- Configurations:
'nsh' A minimal configuration that only enables nsh shell
on a UART
'rpmsg' This configuration is similar to nsh but in addition
it offers the Remote Processing Messaging (RPMsg) service to
enable heterogeneous inter-core communication.

Fix incorrect flag handling and string escaping in the `make host_info`
diagnostic target.
Previously, CFLAGS, CXXFLAGS, and LDFLAGS were passed in a form that caused
improper splitting and quoting, which resulted in malformed output and
incorrectly escaped configuration values such as CONFIG_APPS_DIR.
This change ensures that:
- Compilation flags are passed as proper shell strings
- Flags are split correctly using shlex
- Configuration values are escaped exactly once when generating sysinfo.h
- Parsed output matches the contents of the .config file
This change affects diagnostic output only and does not modify the NuttX
build process or generated binaries.

When the VIRTIO_RPMSG_F_CPUNAME feature is not negotiated, the driver
previously would crash due to DEBUGASSERT. This commit adds support
for a fallback mechanism:
1. Add rpmsg_virtio_probe_cpuname() API that accepts an optional cpuname
parameter to be used when VIRTIO_RPMSG_F_CPUNAME is not available.
2. Modify rptun driver to pass the cpuname from rptun device config
to rpmsg_virtio_probe_cpuname().
3. Refactor rptun device register/unregister to prioritize RPMSG device
handling before other virtio device types.
This ensures the system works correctly in scenarios where the remote
side does not support the VIRTIO_RPMSG_F_CPUNAME feature.

With CONFIG_PAGING enabled and the RISC-V SV39 MMU active, the page fault
handler incorrectly tracked page table levels: `ptprev` pointed to the L1
page table while `ptlevel` indicated L2. This inconsistency caused faulty
virtual address resolution.
This commit fixes the traversal logic to ensure consistent level tracking
across all three page table levels (L1–L3), enabling reliable page fault
handling and on-demand paging.
Additional changes:
- Set PGT_L3_SIZE to 2048 to enable mapping up to 8MB of address space.
- Update knsh_paging config to avoid crashes caused by excessive memory
alignment requirements.
- Add knsh64_paging config to verify this commit works as expected.

This commit refactors nxsched_waitpid() by extracting the core waiting logic
into a separate waittcb() helper function. This change significantly reduces
the cyclomatic complexity of the main function while preserving all original
functionality and improving code maintainability with better separation of
concerns between initialization and wait handling logic.

This commit eliminates the goto statement in nxsched_waitpid() function to

using nested if-else statements to achieve identical functionality while
maintaining MISRA/HIS coding standard compliance and improving code readability.

Add support for ARMv6-M and ARMv8-M Baseline architectures
(Cortex-M0/M0+/M23) in the mcount profiling function. These cores
only support limited Thumb-1 instruction set and require different
assembly instructions compared to ARMv7-M and higher.
Changes:
- Use MOVS+BICS instead of BIC for bit clearing on M0/M23
- Separate register restore for limited push/pop instructions
- Use BX instead of direct POP to PC on M0/M23
