+config HAVE_EFFICIENT_UNALIGNED_ACCESS
+        def_bool n
+        help
+          Some architectures are unable to perform unaligned accesses
+          without the use of get_unaligned/put_unaligned. Others are
+          unable to perform such accesses efficiently (e.g. trap on
+          unaligned access and require fixing it up in the exception
+          handler.)
+
+          This symbol should be selected by an architecture if it can
+          perform unaligned accesses efficiently to allow different
+          code paths to be selected for these cases. Some network
+          drivers, for example, could opt to not fix up alignment
+          problems with received packets if doing so would not help
+          much.
+
+          See Documentation/unaligned-memory-access.txt for more
+          information on the topic of unaligned memory accesses.

-This port to the NEC V850E processor supports the following platforms:
-
-   "sim"
-        The gdb v850e simulator (CONFIG_V850E_SIM).
-
-   "rte-ma1-cb"
-        The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
-        boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E).  This support
-        has only been tested when running with the Multi-debugger monitor
-        ROM (for the Green Hills Multi debugger).  The optional NEC
-        Solution Gear RTE-MOTHER-A motherboard is also supported, which
-        allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).
-
-   "rte-me2-cb"
-        The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
-        This has only been tested using a kernel downloaded via an ICE
-        connection using the Multi debugger.  Support for the RTE-MOTHER-A is
-        present, but hasn't been tested (unlike the other Midas labs cpu
-        boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).
-
-   "as85ep1"
-        The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
-
-   "anna"
-        The NEC `Anna' (board/chip) implementation of the V850E2 processor
-        (CONFIG_V850E2_ANNA).
-
-   "sim85e2c", "sim85e2s"
-        The sim85e2c and sim85e2s simulators, which are verilog simulations
-        of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
-        CONFIG_V850E2_SIM85E2S).
-
-   "fpga85e2c"
-        A FPGA implementation of the V850E2 NA85E2C cpu core
-        (CONFIG_V850E2_FPGA85E2C).
-
-To get a default kernel configuration for a particular platform, you can
-use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
-to see which default configurations are possible, look in the directory
-"arch/v850/configs".
-
-Porting to anything with a V850E/MA1 or MA2 processor should be simple.
-See the file <asm-v850/machdep.h> and the files it includes for an example of
-how to add platform/chip-specific support.

-   (this is like a `bounce buffer').  When a DMA block is `mapped', we
