- * Allocate memory and initialize the FPA pools using memory
- * from cvmx-bootmem. Sizes of each element in the pools is
- * controlled by the cvmx-config.h header file. Specifying

- * @work_queue_entries:
- *               Number of work queue entries
- * @pko_buffers:
- *               PKO Command buffers. You should at minimum have two per
- *               each PKO queue.
- * @tim_buffers:
- *               TIM ring buffer command queues. At least two per timer bucket

- * @dfa_buffers:
- *               DFA command buffer. A relatively small (32 for example)

- * Spec
- *
- * memcpy copies len bytes from src to dst and sets v0 to dst.
- * It assumes that
- *   - src and dst don't overlap
- *   - src is readable
- *   - dst is writable
- * memcpy uses the standard calling convention
- *
- * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
- * the number of uncopied bytes due to an exception caused by a read or write.
- * __copy_user assumes that src and dst don't overlap, and that the call is
- * implementing one of the following:
- *   copy_to_user
- *     - src is readable  (no exceptions when reading src)
- *   copy_from_user
- *     - dst is writable  (no exceptions when writing dst)
- * __copy_user uses a non-standard calling convention; see
- * include/asm-mips/uaccess.h
- *
- * When an exception happens on a load, the handler must
- # ensure that all of the destination buffer is overwritten to prevent
- * leaking information to user mode programs.
- */
-
-/*
- * Implementation
- */
-
-/*
- * The exception handler for loads requires that:
- *  1- AT contain the address of the byte just past the end of the source
- *     of the copy,
- *  2- src_entry <= src < AT, and
- *  3- (dst - src) == (dst_entry - src_entry),
- * The _entry suffix denotes values when __copy_user was called.
- *
- * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
- * (2) is met by incrementing src by the number of bytes copied
- * (3) is met by not doing loads between a pair of increments of dst and src
- *
- * The exception handlers for stores adjust len (if necessary) and return.
- * These handlers do not need to overwrite any data.
- *
- * For __rmemcpy and memmove an exception is always a kernel bug, therefore
- * they're not protected.
