  • 88ced0314   [PATCH] powerpc: sanitize header files for user space includes ... Browse Code »

    include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
    are not meant for use by user space, include/asm-powerpc does
    not have this yet.

    This patch gets us a lot closer there. There are a few cases
    where I was not sure, so I left them out. I have verified
    that no CONFIG_* symbols are used outside of __KERNEL__
    any more and that there are no obvious compile errors when
    including any of the headers in user space libraries.

  • 3ddfbcf19   [PATCH] powerpc: Consolidate asm compatibility macros ... Browse Code »

    This patch consolidates macros used to generate assembly for
    compatibility across different CPUs or configs. A new header,
    asm-powerpc/asm-compat.h contains the main compatibility macros. It
    uses some preprocessor magic to make the macros suitable both for use
    in .S files, and in inline asm in .c files. Headers (bitops.h,
    uaccess.h, atomic.h, bug.h) which had their own such compatibility
    macros are changed to use asm-compat.h.

    ppc_asm.h is now for use in .S files *only*, and a #error enforces
    that. As such, we're a lot more careless about namespace pollution
    here than in asm-compat.h.

    While we're at it, this patch adds a call to the PPC405_ERR77 macro in
    futex.h which should have had it already, but didn't.

    Built and booted on pSeries, Maple and iSeries (ARCH=powerpc). Built
    for 32-bit powermac (ARCH=powerpc) and Walnut (ARCH=ppc).
