Commit ddc94378 changed the definition of __kernel_size_t
from unsigned int to unsigned long.

It is true that it fixed warnings on some crosstools
but it increased warnings on the others.

The problem is that we cannot see consistency in terms of
the typedef of __kernel_size_t on M68K architecture.

However, I'd like to suggest to have __kernel_size_t to be
unsigned int again.

Rationale:

[1] Linux Kernel defines __kernel_size_t on M68K as unsigned int.
    Let's stick to the Linux's way.

[2] We want to build boards with popular pre-built toolchains,
    not the one locally-built by indivisuals.
    I think m68-linux-gcc which can be downloaded from www.kernel.org
    is the candidate for our _recommended_ toolchains.

With this patch, all the m68k boards can be built without any warnings.

Give it a try with the following crosstools:

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/
x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz

or

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/


x86_64-gcc-4.9.0-nolibc_m68k-linux.tar.xz

(The latter is newer.)

The latest GCC is so clever that it reports more warnings
than old ones did:

 ------------------------------>8------------------------------

  board/freescale/m5253demo/flash.c: In function 'flash_get_offsets':
  board/freescale/m5253demo/flash.c:65:23: warning: iteration 2047u
  invokes undefined behavior [-Waggressive-loop-optimizations]
      info->start[k + 1] = info->start[k] + CONFIG_SYS_SST_SECTSZ;
                         ^
  board/freescale/m5253demo/flash.c:64:3: note: containing loop
     for (k = 0, j = 0; j < CONFIG_SYS_SST_SECT; j++, k++) {
     ^

 ------------------------------8<------------------------------

The cause of the warning is like this:

The for statement iterates 2048 times in flash_get_offsets() func.
(Notice CONFIG_SYS_SST_SECT is defined as 2048)

The last iteration does
  info->start[2048] = info->start[2047] + CONFIG_SYS_SST_SECTSZ;
causing an undefined behavior.

(Please note the array size of info->start is 2048.
CONFIG_SYS_MAX_FLASH_SECT is defined as 2048 for this board.)

This commit fixes that so as not to overrun the info->start array.

This has been disabled for ARM in initr_scsi since that function was

I also tested on two random ARM platforms which seem to define CONFIG_CMD_SCSI:
 - highbank worked fine (on midway hardware)
 - omap5_uevm built OK and I confirmed using objdump that things were as

Add more entries to .mailmap for the canonical names with

Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

This tool helps to create/update the mailmap file.

It runs 'git shortlog' internally and searches differently spelled author
names which share the same email address. The author name with the most
commits is asuumed to be a canonical real name. If the number of commits
from the cananonical name is equal to or greater than 'MIN_COMMITS' (=50),
the entry for the cananical name will be output. ('MIN_COMMITS' is used
here because we do not want to create a fat mailmap by adding every author
with only a few commits.)

If there exists a mailmap file specified by the mailmap.file configuration
options or '.mailmap' at the toplevel of the repository, it is used as
a base file.

The base file and the newly added entries are merged together and sorted
alphabetically (but the comment block is kept untouched), and then printed
to standard output.

When this option is enabled, CRLF is treated like LF when importing environments
from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored.

Drawback of enabling this option is that (maybe exported) variables which have
a trailing CR in their content will get imported without that CR. But this
drawback is very unlikely and the big advantage of letting Windows user create
a *working* uEnv.txt too is likely more welcome.
