Following is a patch against 2.4.18-pre3 which fixes a problem where the protection on user stack pages are not marked executable even though the flags indicate the page is executable. Some more aggressive cache flush optimizations may rely on the execution marking to indicate if a page needs to be flushed as it might be present in an icache which is not coherent with the dcache.
Actually, PAGE_COPY happens to be executable on many platforms. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
