    "In addition to migrating the files to use SPDX license headers this
    introduces the ability for clients to operate a hwlock without the
    framework taking any additional locks"

  • acafe7e30   treewide: Use struct_size() for kmalloc()-family ... Browse Code »

    One of the more common cases of allocation size calculations is finding
    the size of a structure that has a zero-sized array at the end, along
    with memory for some number of elements for that array. For example:

    struct foo {
    int stuff;
    void *entry[];
    };

    instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

    Instead of leaving these open-coded and prone to type mistakes, we can
    now use the new struct_size() helper:

    instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);

    This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
    uses. It was done via automatic conversion with manual review for the
    "CHECKME" non-standard cases noted below, using the following Coccinelle
    script:

    // pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
    // sizeof *pkey_cache->table, GFP_KERNEL);
    @@
    identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc";
    expression GFP;
    identifier VAR, ELEMENT;
    expression COUNT;
    @@

    - alloc(sizeof(*VAR) + COUNT * sizeof(*VAR->ELEMENT), GFP)
    + alloc(struct_size(VAR, ELEMENT, COUNT), GFP)

    // mr = kzalloc(sizeof(*mr) + m * sizeof(mr->map[0]), GFP_KERNEL);
    @@
    identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc";
    expression GFP;
    identifier VAR, ELEMENT;
    expression COUNT;
    @@

    - alloc(sizeof(*VAR) + COUNT * sizeof(VAR->ELEMENT[0]), GFP)
    + alloc(struct_size(VAR, ELEMENT, COUNT), GFP)

    // Same pattern, but can't trivially locate the trailing element name,
    // or variable name.
    @@
    identifier alloc =~ "kmalloc|kzalloc|kvmalloc|kvzalloc";
    expression GFP;
    expression SOMETHING, COUNT, ELEMENT;
    @@

    - alloc(sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP)
    + alloc(CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP)

  • f84a8ecfc   hwspinlock/u8500: add hwspinlock driver ... Browse Code »

    Add hwspinlock driver for U8500's Hsem hardware.

    At this point only HSem's protocol 1 is used (i.e. no interrupts).
