-/*
- * 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.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

- * 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.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

- * 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.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

- *
- * The auto-resize feature is useful for device production purposes. For
- * example, different NAND flash chips may have different amount of initial bad
- * eraseblocks, depending of particular chip instance. Manufacturers of NAND
- * chips usually guarantee that the amount of initial bad eraseblocks does not
- * exceed certain percent, e.g. 2%. When one creates an UBI image which will be
- * flashed to the end devices in production, he does not know the exact amount
- * of good physical eraseblocks the NAND chip on the device will have, but this
- * number is required to calculate the volume sized and put them to the volume
- * table of the UBI image. In this case, one of the volumes (e.g., the one
- * which will store the root file system) is marked as "auto-resizable", and
- * UBI will adjust its size on the first boot if needed.
- *
- * Note, first UBI reserves some amount of physical eraseblocks for bad
- * eraseblock handling, and then re-sizes the volume, not vice-versa. This
- * means that the pool of reserved physical eraseblocks will always be present.

- * @padding1: reserved for future, zeroes

- * @padding2: reserved for future, zeroes
- * @hdr_crc: volume identifier header CRC checksum
- *
- * The @sqnum is the value of the global sequence counter at the time when this
- * VID header was created. The global sequence counter is incremented each time
- * UBI writes a new VID header to the flash, i.e. when it maps a logical
- * eraseblock to a new physical eraseblock. The global sequence counter is an
- * unsigned 64-bit integer and we assume it never overflows. The @sqnum
- * (sequence number) is used to distinguish between older and newer versions of
- * logical eraseblocks.
- *
- * There are 2 situations when there may be more then one physical eraseblock
- * corresponding to the same logical eraseblock, i.e., having the same @vol_id
- * and @lnum values in the volume identifier header. Suppose we have a logical
- * eraseblock L and it is mapped to the physical eraseblock P.
- *
- * 1. Because UBI may erase physical eraseblocks asynchronously, the following
- * situation is possible: L is asynchronously erased, so P is scheduled for
- * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
- * so P1 is written to, then an unclean reboot happens. Result - there are 2
- * physical eraseblocks P and P1 corresponding to the same logical eraseblock
- * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
- * flash.
- *
- * 2. From time to time UBI moves logical eraseblocks to other physical
- * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
- * to P1, and an unclean reboot happens before P is physically erased, there
- * are two physical eraseblocks P and P1 corresponding to L and UBI has to
- * select one of them when the flash is attached. The @sqnum field says which
- * PEB is the original (obviously P will have lower @sqnum) and the copy. But
- * it is not enough to select the physical eraseblock with the higher sequence
- * number, because the unclean reboot could have happen in the middle of the
- * copying process, so the data in P is corrupted. It is also not enough to
- * just select the physical eraseblock with lower sequence number, because the
- * data there may be old (consider a case if more data was added to P1 after
- * the copying). Moreover, the unclean reboot may happen when the erasure of P
- * was just started, so it result in unstable P, which is "mostly" OK, but
- * still has unstable bits.
- *
- * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
- * copy. UBI also calculates data CRC when the data is moved and stores it at
- * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
- * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
- * examined. If it is cleared, the situation* is simple and the newer one is
- * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
- * checksum is correct, this physical eraseblock is selected (P1). Otherwise
- * the older one (P) is selected.
- *
- * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
- * in the past. But it is not used anymore and we keep it in order to be able
- * to deal with old UBI images. It will be removed at some point.
- *
- * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
- * Internal volumes are not seen from outside and are used for various internal
- * UBI purposes. In this implementation there is only one internal volume - the
- * layout volume. Internal volumes are the main mechanism of UBI extensions.
- * For example, in future one may introduce a journal internal volume. Internal
- * volumes have their own reserved range of IDs.
- *
- * The @compat field is only used for internal volumes and contains the "degree
- * of their compatibility". It is always zero for user volumes. This field
- * provides a mechanism to introduce UBI extensions and to be still compatible
- * with older UBI binaries. For example, if someone introduced a journal in
- * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
- * journal volume.  And in this case, older UBI binaries, which know nothing
- * about the journal volume, would just delete this volume and work perfectly
- * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
- * - it just ignores the Ext3fs journal.
- *
- * The @data_crc field contains the CRC checksum of the contents of the logical
- * eraseblock if this is a static volume. In case of dynamic volumes, it does
- * not contain the CRC checksum as a rule. The only exception is when the
- * data of the physical eraseblock was moved by the wear-leveling unit, then
- * the wear-leveling unit calculates the data CRC and stores it in the
- * @data_crc field. And of course, the @copy_flag is %in this case.
- *
- * The @data_size field is used only for static volumes because UBI has to know
- * how many bytes of data are stored in this eraseblock. For dynamic volumes,
- * this field usually contains zero. The only exception is when the data of the
- * physical eraseblock was moved to another physical eraseblock for
- * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
- * contents and uses both @data_crc and @data_size fields. In this case, the
- * @data_size field contains data size.
- *
- * The @used_ebs field is used only for static volumes and indicates how many
- * eraseblocks the data of the volume takes. For dynamic volumes this field is
- * not used and always contains zero.
- *
- * The @data_pad is calculated when volumes are created using the alignment
- * parameter. So, effectively, the @data_pad field reduces the size of logical
- * eraseblocks of this volume. This is very handy when one uses block-oriented
- * software (say, cramfs) on top of the UBI volume.

- * If we detect a special mapping then it doesn't have a 'struct page'.

- * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
