staging: mt7621-mmc: Remove unused global dma_size

The global variable dma_size was previously used to select DMA or
non-DMA transfer mode based on the size of the data that should be
transferred. This option was removed preivously, so the variable is not
used any more and can be removed.

staging: mt7621-mmc: Remove transfer mode setting variable

Currently the transfer mode can be chosen between DMA, a size
dependent mode and non-DMA by writing to a proc file. The upstream
driver mtk-sd uses DMA all times. The previous patch removed the
ability to set that option.

Now the remaining uses of the transfer mode setting variable are
cleaned up, because it cannot be changed any more.

Currently the transfer mode can be chosen between DMA, a size
dependent mode and non-DMA by writing to a proc file. The upstream
driver mtk-sd uses DMA all times.

There is no apparent reason why somebody would like to change the
transfer mode and the position of the setting in the debug part of the
driver also indicates, that the option was used for debugging
purposes. So it is removed to clean up the driver and bring it more in
line with the upstream one.

staging: lustre: llite: fix potential missing-check bug when copying lumv

In ll_dir_ioctl(), the object lumv3 is firstly copied from the user space
using Its address, i.e., lumv1 = &lumv3. If the lmm_magic field of lumv3 is
LOV_USER_MAGIC_V3, lumv3 will be modified by the second copy from the user
space. The second copy is necessary, because the two versions (i.e.,
lov_user_md_v1 and lov_user_md_v3) have different data formats and lengths.
However, given that the user data resides in the user space, a malicious
user-space process can race to change the data between the two copies. By
doing so, the attacker can provide a data with an inconsistent version,
e.g., v1 version + v3 data. This can lead to logical errors in the
following execution in ll_dir_setstripe(), which performs different actions
according to the version specified by the field lmm_magic.

This patch rechecks the version field lmm_magic in the second copy.  If the
version is not as expected, i.e., LOV_USER_MAGIC_V3, an error code will be
returned: -EINVAL.
