license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

posix arch: build on aarch64 / allow host-specific cmake includes This change enables specific compiler and linker options to be used in the case that an arch/posix/os.arch.cmake file exists. Note: os and arch in the above case are evaluations of CMAKE_HOST_SYSTEM_NAME and CMAKE_HOST_SYSTEM_PROCESSOR. Otherwise, the existing "generic" compiler and linker flags in arch/posix/CMakeLists.txt are used. Additional flags and checks are provided in arch/posix/Linux.aarch64.cmake. Added scripts/user_wordsize.py to detect if userspace is 64-bit or 32-bit, which should be consistent with the value of CONFIG_64BIT for Aarch64 on Linux.

arch/posix: 64-bit build flags We need to pass -m64 instead of -m32 when CONFIG_64BIT is set. This is pretty x86 centric. Many platforms don't have the ability to select between 32-bits or 64-bits builds and either of those should be dropped in that case with restriction on the available configuration done elsewhere. But for the time being this allows for testing both. Signed-off-by: Nicolas Pitre <npitre@baylibre.com>

# About the -include directive: The reason to do it this way, is because in this
# manner it is transparent to the application. Otherwise posix_cheats.h needs to
# be included in all the applications' files which define main( ), and in any
# app file which uses the pthreads like API provided by Zephyr
# ( include/posix/pthread.h / kernel/pthread.c ) [And any future API added to
# Zephyr which will clash with the native POSIX API] . It would also need to
# be included in a few zephyr kernel files.
