Yes, for example CQ buffers are allocated with:
if (posix_memalign(&buf, dev->page_size,
align(nent * MTHCA_CQ_ENTRY_SIZE, dev->page_size)))
dev->page_size is initialized with:
dev->page_size = sysconf(_SC_PAGESIZE);
so the allocation gives a buffer aligned to the page size, with a size
that is a multiple of the page size.
