+ * What is the most efficient way of loading/storing an unaligned value?
+ *
+ * That is the subject of this file.  Efficiency here is defined as
+ * minimum code size with minimum register usage for the common cases.
+ * It is currently not believed that long longs are common, so we
+ * trade efficiency for the chars, shorts and longs against the long
+ * longs.
+ *
+ * Current stats with gcc 2.7.2.2 for these functions:
+ *
+ *      ptrsize get:    code    regs    put:    code    regs
+ *      1               1       1               1       2
+ *      2               3       2               3       2
+ *      4               7       3               7       3
+ *      8               20      6               16      6
+ *
+ * gcc 2.95.1 seems to code differently:
+ *
+ *      ptrsize get:    code    regs    put:    code    regs
+ *      1               1       1               1       2
+ *      2               3       2               3       2
+ *      4               7       4               7       4
+ *      8               19      8               15      6
+ *
+ * which may or may not be more efficient (depending upon whether
+ * you can afford the extra registers).  Hopefully the gcc 2.95
+ * is inteligent enough to decide if it is better to use the
+ * extra register, but evidence so far seems to suggest otherwise.

- * Each disk drive contains some number of filesystems.
- * A filesystem consists of a number of cylinder groups.
- * Each cylinder group has inodes and data.
- *
- * A filesystem is described by its super-block, which in turn
- * describes the cylinder groups.  The super-block is critical
- * data and is replicated in each cylinder group to protect against
- * catastrophic loss.  This is done at `newfs' time and the critical
- * super-block data does not change, so the copies need not be
- * referenced further unless disaster strikes.
- *
- * For filesystem fs, the offsets of the various blocks of interest
- * are given in the super block as:
- *      [fs->fs_sblkno]         Super-block
- *      [fs->fs_cblkno]         Cylinder group block
- *      [fs->fs_iblkno]         Inode blocks
- *      [fs->fs_dblkno]         Data blocks
- * The beginning of cylinder group cg in fs, is given by
- * the ``cgbase(fs, cg)'' macro.
- *
- * Depending on the architecture and the media, the superblock may
- * reside in any one of four places. For tiny media where every block
- * counts, it is placed at the very front of the partition. Historically,
- * UFS1 placed it 8K from the front to leave room for the disk label and
- * a small bootstrap. For UFS2 it got moved to 64K from the front to leave
- * room for the disk label and a bigger bootstrap, and for really piggy
- * systems we check at 256K from the front if the first three fail. In
- * all cases the size of the superblock will be SBLOCKSIZE. All values are
- * given in byte-offset form, so they do not imply a sector size. The
- * SBLOCKSEARCH specifies the order in which the locations should be searched.
