  • c31ae4bb4   asm-generic: introduce asm/bitsperlong.h ... Browse Code »

    This provides a reliable way for asm-generic/types.h and other
    files to find out if it is running on a 32 or 64 bit platform.

    We cannot use CONFIG_64BIT for this in headers that are included
    from user space because CONFIG symbols are not available there.
    We also cannot do it inside of asm/types.h because some headers
    need the word size but cannot include types.h.

    The solution is to introduce a new header
    that defines both __BITS_PER_LONG for user space and
    BITS_PER_LONG for usage in the kernel. The asm-generic
    version falls back to 32 bit unless the architecture overrides
    it, which I did for all 64 bit platforms.

  • 7dcf2a9fc   remove dummy asm/kvm.h files ... Browse Code »

    This patch removes the dummy asm/kvm.h files on architectures not (yet)
    supporting KVM and uses the same conditional headers installation as
    already used for a.out.h .

    Also removed are superfluous install rules in the s390 and x86 Kbuild
    files (they are already in Kbuild.asm).

  • dd135ebbd   kvm: provide kvm.h for all architecture: fixes headers_install ... Browse Code »

    Currently include/linux/kvm.h is not considered by make headers_install,
    because Kbuild cannot handle " unifdef-$(CONFIG_FOO) += foo.h. This problem
    was introduced by

    commit fb56dbb31c4738a3918db81fd24da732ce3b4ae6

    KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM

    Currently, make headers_check barfs due to , which
    includes, not existing. Rather than add a zillion s, export kvm.
    only if the arch actually supports it.

    which makes this an 2.6.25 regression.

    One way of solving the issue is to enhance Kbuild, but Avi and David conviced
    me, that changing headers_install is not the way to go. This patch changes
    the definition for linux/kvm.h to unifdef-y.

    If  unifdef-y is used for linux/kvm.h "make headers_check" will fail on all
    architectures without asm/kvm.h. Therefore, this patch also provides
    asm/kvm.h on all architectures.

  • 7fa303150   aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUT ... Browse Code »

    Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set.

    Not all architectures support the A.OUT binfmt, so the ELF binfmt should not
    be permitted to go looking for A.OUT libraries to load in such a case. Not
    only that, but under such conditions A.OUT core dumps are not produced either.

    To make this work, this patch also does the following:

    (1) Makes the existence of the contents of linux/a.out.h contingent on
    CONFIG_ARCH_SUPPORTS_AOUT.

    (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT
    core dumping code.

    (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This
    is then included only where needed. This means that this bit of arch
    code will be stored in the appropriate A.OUT binfmt module rather than
    the core kernel.

    (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not
    needed) and FRV.

    This patch depends on the previous patch to move STACK_TOP[_MAX] out of
    asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT
    format is available.

  • ee6baf884   [PATCH] headers_check: remove <asm/timex.h> from user export ... Browse Code »

    There's useful stuff in but has nothing for
    userspace. Stop exporting it, and include it only from within the existing
    #ifdef __KERNEL__ part of

    This fixes a 'make headers_check' failure on i386 because asm-i386/timex.h
    includes both asm-i386/tsc.h and asm-i386/processor.h, neither of which are
    exported to userspace. It's not entirely clear _why_ it includes either of
    these, but it does.
