- Authentication-results: sourceware.org; auth=none
Hi all,
Theis patchset is a continuation of my Linux syscall consolidation
implementation and aimed for SySV IPC (message queue, semaphore,
and shared memory).
Current Linux default implementation only defines the old ipc
syscall method. Architectures need to either to imply the generic
syscalls.list or reimplement the syscall definition. To simplify
and allow to remove some old arch-specific implementation, I added
the direct syscall method for all supported IPC mechanisms.
Other changes are simple code reorganization to simplify and all
compatibility required for various ports.
The patchset also adds 3 simple tests that aims to check for correct
argument passing on syscall. The idea is not to be an extensive
testing of all supported IPC.
Checked on x86_64, i686, armhf, aarch64, and powerpc64le.
