  • Rather than just using pt_regs, it now contains the actual saved
    state explicitly, similar to pt_regs. By doing it this way, we
    provide a cleaner API for userspace (or equivalently, we avoid the
    need for libc to provide its own definition of sigcontext).

    While we're at it, move PT_FLAGS_xxx to where they are not visible
    from userspace. And always pass siginfo and mcontext to signal
    handlers, even if they claim they don't need it, since sometimes
    they actually try to use it anyway in practice.

  • This functionality was stubbed out until recently. Now we support our
    normal backtracing API on TILE-Gx as well as on TILE64/TILEPro.
    This change includes a tweak to the instruction encoding caused by
    adding addxli for compat mode.

  • This commit is primarily changes caused by reviewing "sparse"
    and "checkpatch" output on our sources, so is somewhat noisy, since
    things like "printk() -> pr_err()" (or whatever) throughout the
    codebase tend to get tedious to read. Rather than trying to tease
    apart precisely which things changed due to which type of code
    review, this commit includes various cleanups in the code:

    - sparse: Add declarations in headers for globals.
    - sparse: Fix __user annotations.
    - sparse: Using gfp_t consistently instead of int.
    - sparse: removing functions not actually used.
    - checkpatch: Clean up printk() warnings by using pr_info(), etc.;
    also avoid partial-line printks except in bootup code.
    - checkpatch: Use exposed structs rather than typedefs.
    - checkpatch: Change some C99 comments to C89 comments.

    In addition, a couple of minor other changes are rolled in
    to this commit:

    - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised.
    - Remove some compat code that is unnecessary when we fully eliminate
    some of the deprecated syscalls from the generic syscall ABI.
    - Update the tile_defconfig to reflect current config contents.

  • This change is the core kernel support for TILEPro and TILE64 chips.
    No driver support (except the console driver) is included yet.

    This includes the relevant Linux headers in asm/; the low-level
    low-level "Tile architecture" headers in arch/, which are
    shared with the hypervisor, etc., and are build-system agnostic;
    and the relevant hypervisor headers in hv/.
