    to math64.h as currently no architecture overrides the generic implementation.
    They can still override it of course, but the duplicated declarations are

  • 6510d4195   kernel: Move arches to use common unaligned access ... Browse Code »

    Unaligned access is ok for the following arches:
    cris, m68k, mn10300, powerpc, s390, x86

    Arches that use the memmove implementation for native endian, and
    the byteshifting for the opposite endianness.
    h8300, m32r, xtensa

    Packed struct for native endian, byteshifting for other endian:
    alpha, blackfin, ia64, parisc, sparc, sparc64, mips, sh

    m86knommu is generic_be for Coldfire, otherwise unaligned access is ok.

    frv, arm chooses endianness based on compiler settings, uses the byteshifting
    versions. Remove the unaligned trap handler from frv as it is now unused.

    v850 is le, uses the byteshifting versions for both be and le.

    Remove the now unused asm-generic implementation.

  • 7e675137a   mm: introduce pte_special pte bit ... Browse Code »

    s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory
    model (which is more dynamic than most). Instead, they had proposed to
    implement it with an additional path through vm_normal_page(), using a bit in
    the pte to determine whether or not the page should be refcounted:

    vm_normal_page()
    {
    ...
    if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) {
    if (vma->vm_flags & VM_MIXEDMAP) {
    #ifdef s390
    if (!mixedmap_refcount_pte(pte))
    return NULL;
    #else
    if (!pfn_valid(pfn))
    return NULL;
    #endif
    goto out;
    }
    ...
    }

    This is fine, however if we are allowed to use a bit in the pte to determine
    refcountedness, we can use that to _completely_ replace all the vma based
    schemes. So instead of adding more cases to the already complex vma-based
    scheme, we can have a clearly seperate and simple pte-based scheme (and get
    slightly better code generation in the process):

    vm_normal_page()
    {
    #ifdef s390
    if (!mixedmap_refcount_pte(pte))
    return NULL;
    return pte_page(pte);
    #else
    ...
    #endif
    }

    And finally, we may rather make this concept usable by any architecture rather
    than making it s390 only, so implement a new type of pte state for this.
    Unfortunately the old vma based code must stay, because some architectures may
    not be able to spare pte bits. This makes vm_normal_page a little bit more
    ugly than we would like, but the 2 cases are clearly seperate.

    So introduce a pte_special pte state, and use it in mm/memory.c. It is
    currently a noop for all architectures, so this doesn't actually result in any
    compiled code changes to mm/memory.o.

    BTW:
    I haven't put vm_normal_page() into arch code as-per an earlier suggestion.
    The reason is that, regardless of where vm_normal_page is actually
    implemented, the *abstraction* is still exactly the same. Also, while it
    depends on whether the architecture has pte_special or not, that is the
    only two possible cases, and it really isn't an arch specific function --
    the role of the arch code should be to provide primitive functions and
    accessors with which to build the core code; pte_special does that. We do
    not want architectures to know or care about vm_normal_page itself, and
    we definitely don't want them being able to invent something new there
    out of sight of mm/ code. If we made vm_normal_page an arch function, then
    we have to make vm_insert_mixed (next patch) an arch function too. So I
    don't think moving it to arch code fundamentally improves any abstractions,
    while it does practically make the code more difficult to follow, for both
    mm and arch developers, and easier to misuse.

    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.

  • 2f569afd9   CONFIG_HIGHPTE vs. sub-page page tables. ... Browse Code »

    Background: I've implemented 1K/2K page tables for s390. These sub-page
    page tables are required to properly support the s390 virtualization
    instruction with KVM. The SIE instruction requires that the page tables
    have 256 page table entries (pte) followed by 256 page status table entries
    (pgste). The pgstes are only required if the process is using the SIE
    instruction. The pgstes are updated by the hardware and by the hypervisor
    for a number of reasons, one of them is dirty and reference bit tracking.
    To avoid wasting memory the standard pte table allocation should return
    1K/2K (31/64 bit) and 2K/4K if the process is using SIE.

    Problem: Page size on s390 is 4K, page table size is 1K or 2K. That means
    the s390 version for pte_alloc_one cannot return a pointer to a struct
    page. Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one
    cannot return a pointer to a pte either, since that would require more than
    32 bit for the return value of pte_alloc_one (and the pte * would not be
    accessible since its not kmapped).

    Solution: The only solution I found to this dilemma is a new typedef: a
    pgtable_t. For s390 pgtable_t will be a (pte *) - to be introduced with a
    later patch. For everybody else it will be a (struct page *). The
    additional problem with the initialization of the ptl lock and the
    NR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and
    a destructor pgtable_page_dtor. The page table allocation and free
    functions need to call these two whenever a page table page is allocated or
    freed. pmd_populate will get a pgtable_t instead of a struct page pointer.
    To get the pgtable_t back from a pmd entry that has been installed with
    pmd_populate a new function pmd_pgtable is added. It replaces the pmd_page
    call in free_pte_range and apply_to_pte_range.

  • bdc807871   avoid overflows in kernel/time.c ... Browse Code »

    When the conversion factor between jiffies and milli- or microseconds is
    not a single multiply or divide, as for the case of HZ == 300, we currently
    do a multiply followed by a divide. The intervening result, however, is
    subject to overflows, especially since the fraction is not simplified (for
    HZ == 300, we multiply by 300 and divide by 1000).

    This is exposed to the user when passing a large timeout to poll(), for
    example.

    This patch replaces the multiply-divide with a reciprocal multiplication on
    32-bit platforms. When the input is an unsigned long, there is no portable
    way to do this on 64-bit platforms there is no portable way to do this
    since it requires a 128-bit intermediate result (which gcc does support on
    64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but
    since the output is a 32-bit integer in the cases affected, just simplify
    the multiply-divide (*3/10 instead of *300/1000).

    The reciprocal multiply used can have off-by-one errors in the upper half
    of the valid output range. This could be avoided at the expense of having
    to deal with a potential 65-bit intermediate result. Since the intent is
    to avoid overflow problems and most of the other time conversions are only
    semiexact, the off-by-one errors were considered an acceptable tradeoff.

    At Ralf Baechle's suggestion, this version uses a Perl script to compute
    the necessary constants. We already have dependencies on Perl for kernel
    compiles. This does, however, require the Perl module Math::BigInt, which
    is included in the standard Perl distribution starting with version 5.8.0.
    In order to support older versions of Perl, include a table of canned
    constants in the script itself, and structure the script so that
    Math::BigInt isn't required if pulling values from said table.

    Running the script requires that the HZ value is available from the
    Makefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the
    architectures which didn't already have it (alpha, cris, frv, h8300, m32r,
    m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or
    sh64 architectures, since Paul Mundt has dealt with those separately in the
    sh tree.

  • 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.

  • 622a9edd9   Remove dma_cache_(wback|inv|wback_inv) functions ... Browse Code »

    dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
    cache managment API for I/O purposes. Originally it was basically the raw
    MIPS low level cache API exported to the entire world. The API has
    suffered from a lack of documentation, was not very widely used unlike it's
    more modern brothers and can easily be replaced by dma_cache_sync. So
    remove it rsp. turn the surviving bits back into an arch private API, as
    discussed on linux-arch.

  • cba4fbbff   remove include/asm-*/ipc.h ... Browse Code »

    All asm/ipc.h files do only #include .

    This patch therefore removes all include/asm-*/ipc.h files and moves the
    contents of include/asm-generic/ipc.h to include/linux/ipc.h.

    AUTO_DMA and FLOPPY_MOTOR_MASK in include/asm-*/floppy.h are dead symbols -
    remove them.

  • 68a9bd0cd   remove strict ansi check from __u64 in asm/types.h ... Browse Code »

    Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
    32bit targets.

    GCC can be made to warn about usage of long long types with ISO C90
    (-ansi), but only with -pedantic. You can write this in a way that even
    then it doesn't cause warnings, namely by:

    #ifdef __GNUC__
    __extension__ typedef __signed__ long long __s64;
    __extension__ typedef unsigned long long __u64;
    #endif

    The __extension__ keyword in front of this switches off any pedantic
    warnings for this expression.

  • 04fc8bbcf   kill DECLARE_MUTEX_LOCKED ... Browse Code »

    DECLARE_MUTEX_LOCKED was used for semaphores used as completions and we've
    got rid of them. Well, except for one in libusual that the maintainer
    explicitly wants to keep as semaphore. So convert that useage to an
    explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is
    reminded to use a completion.
