[Feature] rtt进入临界区直接粗暴的关掉全局中断，为何不像FreeRtos那样，只关闭受操作系统管理的中断，而不关闭不受操作系统管理的中断

Start with libcpu/arm/cortex-m4/context_gcc.S, especially rt_hw_interrupt_disable, and compare its PRIMASK handling with the referenced FreeRTOS portmacro.h BASEPRI implementation. Determine the required RT-Thread behavior for interrupts outside OS management and verify the result on the stated STM32/GCC Cortex-M4 setup.
