arvinzzz 33d0c1bd0b refactor: 内核目录结构整理 
1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理
2. Kconfig分层，各模块自己的配置放到自己目录下管理
3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理

LiteOS2021 dc9ec6856f feat: L0-L1 支持Trace 
1.【需求描述】
            L0~L1 支持Trace，提供两种工作模式：在线模式、离线缓存模式， 用于按时间线追踪系统事件，如任务切换、中断、ipc等。
        2.【方案描述】
            L0:
            (1).在内核模块预置静态代码桩
            (2).触发桩后，收集系统上下文信息
            (3).离线模式则写入内存，用户可通过dump导出；
            (4).在线模式通过pipeline对接IDE进行可视化解析和展示；
            L1:
            新增trace字符设备，位于"/dev/trace",通过对设备节点的read\write\ioctl，实现用户态trace；

        BREAKING CHANGE:
        1.新增一系列trace的对外API，位于los_trace.h中.
        LOS_TRACE_EASY简易插桩
        LOS_TRACE标准插桩
        LOS_TraceInit配置Trace缓冲区的地址和大小
        LOS_TraceStart开启事件记录
        LOS_TraceStop停止事件记录
        LOS_TraceRecordDump输出Trace缓冲区数据
        LOS_TraceRecordGet获取Trace缓冲区的首地址
        LOS_TraceReset清除Trace缓冲区中的事件
        LOS_TraceEventMaskSet设置事件掩码，仅记录某些模块的事件
        LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数

YOUR_NAME 35a2f3af33 fix: init进程收到子进程退出信号后，调用fork重新拉起进程，会导致系统卡死 
问题原因：init进程执行信号时，线程栈底预留了部分空间给信号上下文使用，
从而导致处理信号时线程栈底比线程控制块里面记录的大，这样在fork的过程中内核
从init线程栈底copy线程上下文给新进程时，copy的不是实际运行的栈底，以致于
新进程的线程上下文不对，在实际运行时跑飞，引发系统卡死。
解决方案：在fork过程copy线程上下文时，判断是否预留了信号上下文空间，如果预留
了，则copy的栈底要基于预留后的栈底去copy线程上下文。

Haryslee 9547133e64 fix：修复llvm编译环境下内核态内存调测调用栈信息解析有误的问题 
背景：内核态内存调测调用栈信息在gcc编译环境下是准确的，但是llvm
编译环境下是错误的，分析知，gcc和llvm编译环境下fp和lr的对应关系
是有区别的。
修复：增加llvm编译环境下对lr解析的逻辑，并用编译宏控制。

qidechun a195aac9fb feat: add blackbox for liteos_a 
1、在内核增加BlackBox核心框架，对外提供模块回调接口注册和故障处理接口。
2、增加默认的系统模块适配层，处理通用内核态和用户态故障日志抓取和保存。
3、BBOX特性默认关闭，若想使用此特性，请在内核配置文件中增加如下编译选项：
LOSCFG_BLACKBOX=y
LOSCFG_SAVE_EXCINFO=y
LOSCFG_SAVE_EXCINFO可以帮助抓取更多的故障日志。
4、若已经打开BBOX特性，想快速验证此特性，请添加如下编译选项：
LOSCFG_HIDUMPER=y

zhushengle cf89f016e9 fix: 解决kill进程时无法保证进程的已持有的内核资源合理释放. 
背景: 当前信号实现原理是在系统调用结束和中断结束时检查是否有信号处理,
      如果有信号处理就切去处理信号，信号处理结束后回来继续按原来流程执行。
问题：当用户态线程在执行系统调用或缺页异常时，运行在内核态，如果此时有信
      号需要处理，且该线程已经持有了部分内核资源(如：锁，内存等), 此时如
      果有中断发生，则在中断结束时，就会去处理该信号，此时用户态线程持有
      了内核未释放的资源跑到了用户态去运行，如果该线程在用户态出现问题,
      那么它持有的内核资源就无法被释放了。
方案：用户态线程在执行系统调用和缺页异常时暂时屏蔽信号，防止此时有中断去
      处理信号，等系统调用结束或缺页异常结束时再去处理信号。
解决的问题：
  1. 执行系统调用或缺页异常时屏蔽信号，防止中断去处理信号
  2.解决无法kill 因为用户态的锁、ipc等阻塞的用户态线程
  3.进程退出方式转变为: 依次通过kill去杀死该进程的所有线程
