Slightly more reduced:

struct list {
  struct list *next, *prev;
};

struct page {
  struct list list;
  int index;
  int counter;
};

int bits, table;

int
foo (struct page *page, struct list *head, int offset)
{
  int value = (offset >> bits) & (1 << bits);
  int hash = table + value;

  page->index |= 1;

  {
    int *v = &page->counter;
    int flags;

    asm volatile ("" : "=r" (flags) :             : "er0");
    (*v)++;
    asm volatile ("" :              : "r" (flags) : "er0");
  }

  page->index = offset;

  {
    struct list *new = &page->list;
    struct list *prev = head;
    struct list *next = head->next;

    next->prev = new;
    new->next = next;
    new->prev = prev;
    prev->next = new;
  }

  return (int) page + hash;
}
