  • d148eac0e   Kbuild: rename HAVE_CC_STACKPROTECTOR config variable ... Browse Code »

    HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
    canary implementation. It is not about the compiler support.

    For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
    CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
    config symbol.

    I moved the 'select' lines to keep the alphabetical sorting.

  • 1ea5afd42   Documentation: arch-support: remove obsolete architectures ... Browse Code »

    A number of architecture ports are obsolete and getting dropped,
    so we no longer want to track the respective features.

    We already removed the lines for metag and mn10300, this does
    the same edits for all the others.

    For the remaining 21 architectures, this shows how many are known
    to implement each given feature:

    pr_debug
    - use struct exc_table instead of flat array for exception handling
    data

    - build kernel with -mtext-section-literals; simplify xtensa linker
    script

    - fix futex_atomic_cmpxchg_inatomic()

  • c633544a6   xtensa: add support for KASAN ... Browse Code »

    Cover kernel addresses above 0x90000000 by the shadow map. Enable
    HAVE_ARCH_KASAN when MMU is enabled. Provide kasan_early_init that fills
    shadow map with writable copies of kasan_zero_page. Call
    kasan_early_init right after mmu initialization in the setup_arch.
    Provide kasan_init that allocates proper shadow map pages from the
    memblock and puts these pages into the shadow map for addresses from
    VMALLOC area to the end of KSEG. Call kasan_init right after memblock
    initialization. Don't use KASAN for the boot code, MMU and KASAN
    initialization and page fault handler. Make kernel stack size 4 times
    larger when KASAN is enabled to avoid stack overflows.
    GCC 7.3, 8 or newer is required to build the xtensa kernel with KASAN.

    Pull powerpc updates from Michael Ellerman:
    "Highlights include:

    - Larger virtual address space on 64-bit server CPUs. By default we
    use a 128TB virtual address space, but a process can request access
    to the full 512TB by passing a hint to mmap().

    - Support for the new Power9 "XIVE" interrupt controller.

    - TLB flushing optimisations for the radix MMU on Power9.

    - Support for CAPI cards on Power9, using the "Coherent Accelerator
    Interface Architecture 2.0".

    - The ability to configure the mmap randomisation limits at build and
    runtime.

    - Several small fixes and cleanups to the kprobes code, as well as
    support for KPROBES_ON_FTRACE.

    - Major improvements to handling of system reset interrupts,
    correctly treating them as NMIs, giving them a dedicated stack and
    using a new hypervisor call to trigger them, all of which should
    aid debugging and robustness.

    - Many fixes and other minor enhancements.

  • ead514d5f   powerpc/kprobes: Add support for KPROBES_ON_FTRACE ... Browse Code »

    Allow kprobes to be placed on ftrace _mcount() call sites. This optimization
    avoids the use of a trap, by riding on ftrace infrastructure.

    This depends on HAVE_DYNAMIC_FTRACE_WITH_REGS which depends on MPROFILE_KERNEL,
    which is only currently enabled on powerpc64le with newer toolchains.

    Based on the x86 code by Masami.
