  • 16f3e95b3   cross-arch: don't corrupt personality flags upon exec() ... Browse Code »

    Historically, the top three bytes of personality have been used for
    things such as ADDR_NO_RANDOMIZE, which made sense only for specific
    architectures.

    We now however have a flag there that is general no matter the
    architecture (UNAME26); generally we have to be careful to preserve the
    personality flags across exec().

    This patch tries to fix all architectures that forcefully overwrite
    personality flags during exec() (ppc32 and s390 have been fixed recently
    by commits f9783ec862ea ("[S390] Do not clobber personality flags on
    exec") and 59e4c3a2fe9c ("powerpc/32: Don't clobber personality flags on
    exec") in a similar way already).

  • 16a801637   sanitize tsk_is_polling() ... Browse Code »

    Make default just return 0. The current default (checking
    TIF_POLLING_NRFLAG) is taken to architectures that need it;
    ones that don't do polling in their idle threads don't need
    to defined TIF_POLLING_NRFLAG at all.

    ia64 defined both TS_POLLING (used by its tsk_is_polling())
    and TIF_POLLING_NRFLAG (not used at all). Killed the latter...

  • 786d35d45   Make most arch asm/module.h files use asm-generic/module.h ... Browse Code »

    Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
    ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
    into asm-generic/module.h for all arches bar MIPS.

    Also, use the generic definition mod_arch_specific where possible.

    To this end, I've defined three new config bools:

    (*) HAVE_MOD_ARCH_SPECIFIC

    Arches define this if they don't want to use the empty generic
    mod_arch_specific struct.

    (*) MODULES_USE_ELF_RELA

    Arches define this if their modules can contain RELA records. This causes
    the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
    defined by the arch rather than have the core emit an error message.

    (*) MODULES_USE_ELF_REL

    Arches define this if their modules can contain REL records. This causes
    the Elf_Rel mapping to be emitted and allows apply_relocate() to be
    defined by the arch rather than have the core emit an error message.

    Note that it is possible to allow both REL and RELA records: m68k and mips are
    two arches that do this.

    With this, some arch asm/module.h files can be deleted entirely and replaced
    with a generic-y marker in the arch Kbuild file.

    Additionally, I have removed the bits from m32r and score that handle the
    unsupported type of relocation record as that's now handled centrally.

  • c1d7e01d7   ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION ... Browse Code »

    Rather than #define the options manually in the architecture code, add
    Kconfig options for them and select them there instead. This also allows
    us to select the compat IPC version parsing automatically for platforms
    using the old compat IPC interface.

    Pull KVM changes from Avi Kivity:
    "Changes include additional instruction emulation, page-crossing MMIO,
    faster dirty logging, preventing the watchdog from killing a stopped
    guest, module autoload, a new MSI ABI, and some minor optimizations
    and fixes. Outside x86 we have a small s390 and a very large ppc
    update.

    Regarding the new (for kvm) rebaseless workflow, some of the patches
    that were merged before we switch trees had to be rebased, while
    others are true pulls. In either case the signoffs should be correct
    now."

    Fix up trivial conflicts in Documentation/feature-removal-schedule.txt
    arch/powerpc/kvm/book3s_segment.S and arch/x86/include/asm/kvm_para.h.

    I suspect the kvm_para.h resolution ends up doing the "do I have cpuid"
    check effectively twice (it was done differently in two different
    commits), but better safe than sorry ;)

    Pull fpu state cleanups from Ingo Molnar:
    "This tree streamlines further aspects of FPU handling by eliminating
    the prepare_to_copy() complication and moving that logic to
    arch_dup_task_struct().

    It also fixes the FPU dumps in threaded core dumps, removes and old
    (and now invalid) assumption plus micro-optimizes the exit path by
    avoiding an FPU save for dead tasks."

    Fixed up trivial add-add conflict in arch/sh/kernel/process.c that came
    in because we now do the FPU handling in arch_dup_task_struct() rather
    than the legacy (and now gone) prepare_to_copy().
