  • a872eb213   mm: fix RODATA_TEST failure "rodata_test: test data was not read only" ... Browse Code »

    On powerpc, RODATA_TEST fails with message the following messages:

    Freeing unused kernel memory: 528K
    rodata_test: test data was not read only

    This is because GCC allocates it to .data section:

    c0695034 g O .data 00000004 rodata_test_data

    Since commit 056b9d8a7692 ("mm: remove rodata_test_data export, add
    pr_fmt"), rodata_test_data is used only inside rodata_test.c By
    declaring it static, it gets properly allocated into .rodata section
    instead of .data:

    c04df710 l O .rodata 00000004 rodata_test_data

    Since commit 3ad38ceb2769 ("x86/mm: Remove CONFIG_DEBUG_NX_TEST"),
    nothing is using the exported rodata_test_data variable, so drop the
    export.

    This additionally updates the pr_fmt to avoid redundant strings and
    adjusts some whitespace.

  • 2959a5f72   mm: add arch-independent testcases for RODATA ... Browse Code »

    This patch makes arch-independent testcases for RODATA. Both x86 and
    x86_64 already have testcases for RODATA, But they are arch-specific
    because using inline assembly directly.

    And cacheflush.h is not a suitable location for rodata-test related
    things. Since they were in cacheflush.h, If someone change the state of
    CONFIG_DEBUG_RODATA_TEST, It cause overhead of kernel build.

    To solve the above issues, write arch-independent testcases and move it
    to shared location.
