[PATCH v2] Use kernel alloc wrappers and fix wargings

[Kari Argillander]

In ntfs3 driver there is allocation made like this ntfs_malloc().
Patch 2/3 will converter these to kernel ones like kmalloc(). After I
did this then checkpatch raise warnings about array allocations so I
fix these in patch 3/3.

I also notice when I made patch that there is broken utf8 char so I
wanted first fix that because it raised some warning in my editor and
did not want to "break" patch 2/3. So patch 1/3 address that.

v2:
 - Add patch 1/3 because I found broken utf8 char in source file
 - Add another patch 2/2 which will fix allocation warnings
 - Rewrite some of commit message from first patch

[PATCH v2] fs/ntfs3: Fix one none utf8 char in source file

[Kari Argillander]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=UTF-8, Size: 1159 bytes --]

In one source file there is for some reason non utf8 char. But hey this
is fs development so this kind of thing might happen.

I tested this for my self and at least it apply. Hopefully will apply also
there.

[PATCH v2] fs/ntfs3: Do not use driver own alloc wrappers

[Kari Argillander]

Problem with these wrapper is that we cannot take off example GFP_NOFS
flag. It is not recomended use those in all places. Also if we change
one driver specific wrapper to kernel wrapper then it would look really
weird. People should be most familiar with kernel wrappers so let's just
use those ones.

Driver specific alloc wrapper also confuse some static analyzing tools,
good example is example kernels checkpatch tool. After we converter
these to kernel specific then warnings is showed.

Following Coccinelle script was used to automate changing.

[PATCH v2] fs/ntfs3: Use kcalloc/kmalloc_array over kzalloc/kmalloc

[Kari Argillander]

Use kcalloc/kmalloc_array over kzalloc/kmalloc when we allocate array.
Checkpatch found these after we did not use our own defined allocation
wrappers.

This is not an exact transformation.
This allocates zeroed memory.
Use kmalloc_array here instead.
