Commits on Jul 1, 2024

  1. remove return code of handlers 

    The return codes are not checked anywhere, so they serve no practical
purpose. Remove them to avoid giving false hopes that any caller will
eventually care or even handle errors.

  11. add seL4_DebugNameThreadFmt() 

    This is a convenient way to create thread names dynamically.
Also change seL4_DebugNameThread() to use strncpy() instead of
strcpy() to honor the IPC buffer size.

  13. boot/smp: use memory order aware builtin functions 

    In C++11 memory order aware access functions were introduced, these
are available in C also. Use them to allow the compiler choosing
proper barriers automatically.

  14. boot/smp: use local mask to detect core start 

    Use a local mask variable concurrently to detect secondary core start
instead of incrementing ksNumCPUs. This give the compiler full control
over the concurrent accesses, ksNumCPUs is just set at the end when all
cores are up.
