This is a *breaking API change* This commit: * makes seL4_Fault_tag_t common between the kernel and libsel4 * deprecates the existing functions from sel4/messages.h includes * introduces a new fault API in sel4/faults.h and * sel4/sel4_arch/faults.h * deprecates seL4_GetTag(), as the function did not work without the user calling seL4_SetTag() first (seL4_MessageInfo is passed in registers and not set in the IPC buffer) * removes previously deprecated functions (deprecated prior to 3.0.0) * updates the seL4 manual to reflect the changes
