1c5a0bf6cc irq: add [enter|leave]_critical_section_nonirq
Configuring NuttX and compile:
$ ./tools/configure.sh -l qemu-armv8a:nsh_smp
$ make
Running with qemu
$ qemu-system-aarch64 -cpu cortex-a53 -smp 4 -nographic \
   -machine virt,virtualization=on,gic-version=3 \
   -net none -chardev stdio,id=con,mux=on -serial chardev:con \
   -mon chardev=con,mode=readline -kernel ./nuttx

reason:
In some non-irq scenarios, we can simplify
the implementation of critical sections to improve performance.

6ee9ec7656 build: add initial cmake build system
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)

------------------

How to test

From within nuttx/. Configure:

cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja

(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja

This uses ninja generator (install with sudo apt install ninja-build). To build:

$ cmake --build build

menuconfig:

$ cmake --build build -t menuconfig

--------------------------

2. cmake/build: reformat the cmake style by cmake-format

https://github.com/cheshirekow/cmake_format

$ pip install cmakelang

$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

b3d45fd6c0 sched/mqueue: remove unused leave_cancellation_point
should be removed by:

commit fca07be1df
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Tue Oct 10 08:43:10 2017 -0600

    Squashed commit of the following:

        Change all calls to mq_send() and mq_timedsend() in the OS to calls to
        nxmq_send() and nxmq_timedsend(), making appropriate changes for differences
        in return values.

        sched/mqueue:  Add internal function nxmq_send() and nxmq_timedsend() that are
        equivalent to mq_send() and mq_timedsend() except that they do not create
        cancellation points and do to not modify the errno variable.
