NUM_MEM_REGIONS / NUM_CONFIGURABLE_REGIONS / NUM_EXCLUSIVE_REGIONS had no
Kconfig defaults. Enabling RT_USING_HW_STACK_GUARD without explicitly
setting them generated empty macros in rtconfig.h (e.g.
'#define NUM_CONFIGURABLE_REGIONS'), which expanded into invalid C
expressions like '(2 + )' and 'for (i = 0U; i < ; i++)', breaking
compilation for cortex-m4/m7/m33 MPU code.
Add safe defaults: NUM_MEM_REGIONS=8, NUM_CONFIGURABLE_REGIONS=0,
NUM_EXCLUSIVE_REGIONS=0. Also document the MemManage_Handler strong-symbol
conflict with CubeMX-generated stm32f4xx_it.c and how to resolve it.

Without CXX = rtconfig.CXX the scons Environment falls back to the
default host 'g++', and CXXFLAGS stays an empty CLVar, so the C++
group flags appended by DefineGroup end up as a single unquoted
argument and the build fails as soon as RT_USING_CPLUSPLUS is on:
g++: error: -fno-exceptions -fno-rtti ... -Wl,--gc-sections:
linker input file not found: No such file or directory
Found by the CI C++ ctor (.init_array) check.
The terminal subsystem's own headers (terminal.h, tty_config.h, ...) are
resolved by the compiler's quoted-include directory lookup for sources
inside components/lwp/terminal; nothing else depends on the path.
Stop polluting the global CPPPATH with this internal directory,
following the convention discussed in #10980.
When sal_socket() rejects a request, DFS v2 descriptor cleanup destroys the dfs_file but leaves its separately allocated vnode behind.
Destroy the vnode before releasing the failed descriptor and add a regression test that verifies repeated failures do not consume heap.

Grow maps without a 256 VMA cap, skip RSS walks for maps, report
matching status text, real RSS/statm, MemAvailable after page-pool
free pages, load averages plus last PID, cumulative processes, RV32
cpuinfo, and per-character mount escaping.
NULL read/write buffers now return -EFAULT. tmpfs setattr uses the
vnode-backed object after unlink, keeps S_ISUID/S_ISGID/S_ISVTX, and
the tmpfs utest checks ENAMETOOLONG plus post-unlink fchmod.
Pass -mpoke-function-name to the compiler and assembler when
RT_BACKTRACE_FUNCTION_NAME is enabled for the Cortex-A9 QEMU BSP.
Keep the BSP configuration opt-in so users can enable symbolized
backtraces through menuconfig without changing the default build.
The flag is appended through CCFLAGS and ASPPCOM after the build
environment is created instead of concatenating it into
CFLAGS/CXXFLAGS/ASFLAGS: when the toolchain is selected with
--exec-path, PrepareBuilding() reloads rtconfig and
_apply_exec_path_override() overwrites those variables, which would
silently drop the option. The build still succeeds but function names
are missing from the text section, leaving backtraces without usable
frames.
Example backtrace in QEMU (vexpress-a9, RT_BACKTRACE_FUNCTION_NAME=y,
fault triggered from msh through cmd_fault -> fault_level1 ->
fault_level2 -> fault_level3):
backtrace:
0x600475a8 @ fault_level3
0x600475dc @ fault_level2
0x60047608 @ fault_level1
0x60047630 @ cmd_fault
0x6006ca80 @ _msh_exec_cmd
0x6006cb3c @ msh_exec

Enable RT_USING_HW_STACK_GUARD on Cortex-M4, which was previously only
available on Cortex-M7 and Cortex-M33.
Core porting (libcpu/arm/cortex-m4/):
- Add mpu.c/mpu.h/mputype.h aligned with the Cortex-M7 MPU layer. The only
difference is the default memory type attribute: Cortex-M4 has no L1 cache,
so the cacheability bits are reduced to three cases.
- Add rt_hw_stack_guard_init() to cpuport.c.
- Add missing #include <rtconfig.h> to context_gcc.S and invoke
rt_hw_mpu_table_switch() in the PendSV context switch path.
- Update SConscript to exclude mpu.c when memory protection is disabled.
BSP reference (bsp/stm32/stm32f407-fk407m2-zgt6/):
- board.h: include rtthread.h and define NUM_STATIC_REGIONS.
- board.c: define static_regions[] marking the Flash region read-only,
guarded by RT_USING_MEM_PROTECTION so it is not enabled by default.
