  • 5ca43f6c3   lib: consolidate DEBUG_STACK_USAGE option ... Browse Code »

    Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it
    to lib/Kconfig.debug so each arch doesn't have to define it. This
    obviously makes the option generic, but that's fine because the config is
    already used in generic code.

    It's not obvious to me that sysrq-P actually does anything caution by
    keeping the most inclusive wording.

  • 4cb6066af   sparc: Kill user copy check code. ... Browse Code »

    For whatever reason GCC isn't able to figure things out in
    the control flow (in particular when min() and max() expressions
    are involved) on sparc as well as it can on x86.

    So lots of useless incorrect user copy warnings get spewed and the
    full-on compile failure mode of the user copy checks were never usable
    on sparc at all.

    People can debug these kinds of problems on x86.

  • ee3b4290a   generic debug pagealloc: build fix ... Browse Code »

    This fixes a build failure with generic debug pagealloc:

    mm/debug-pagealloc.c: In function 'set_page_poison':
    mm/debug-pagealloc.c:8: error: 'struct page' has no member named 'debug_flags'
    mm/debug-pagealloc.c: In function 'clear_page_poison':
    mm/debug-pagealloc.c:13: error: 'struct page' has no member named 'debug_flags'
    mm/debug-pagealloc.c: In function 'page_poison':
    mm/debug-pagealloc.c:18: error: 'struct page' has no member named 'debug_flags'
    mm/debug-pagealloc.c: At top level:
    mm/debug-pagealloc.c:120: error: redefinition of 'kernel_map_pages'
    include/linux/mm.h:1278: error: previous definition of 'kernel_map_pages' was here
    mm/debug-pagealloc.c: In function 'kernel_map_pages':
    mm/debug-pagealloc.c:122: error: 'debug_pagealloc_enabled' undeclared (first use in this function)

    by fixing

    - debug_flags should be in struct page
    - define DEBUG_PAGEALLOC config option for all architectures

    CONFIG_DEBUG_PAGEALLOC is now supported by x86, powerpc, sparc64, and
    s390. This patch implements it for the rest of the architectures by
    filling the pages with poison byte patterns after free_pages() and
    verifying the poison patterns before alloc_pages().

    This generic one cannot detect invalid page accesses immediately but
    invalid read access may cause invalid dereference by poisoned memory and
    invalid write access can be detected after a long delay.

  • e8dd16129   [SPARC32]: Add irqflags.h to sparc32 and use it from generic code. ... Browse Code »

    Added asm-sparc/irqflags.h and moved irq related code from system.h to it.
    Renamed local_irq functions to raw_local_irq in irq.c.
    Modified system.h to include linux/irqflags.h which includes asm/irqflags.h.
    Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.

    This is the first step in adding IRQ-flags state tracing as outlined in
    Documentation/irqflags-tracing.txt. These changes should be harmless
    because they just move things around and rename them.

    The next step is making the lowlevel entry code modifications which
    to be honest are beyond my capabilities at this point.

    Boot tested on an ss20 running an SMP kernel.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
