This patch set introduces sg_pcopy_from_buffer() and sg_pcopy_to_buffer(),
which copy data between a linear buffer and an SG list.

The only difference between sg_pcopy_{from,to}_buffer() and
sg_copy_{from,to}_buffer() is an additional argument that specifies
the number of bytes to skip the SG list before copying.

The main reason for introducing these functions is to fix a problem
in scsi_debug module.  And there is a local function in crypto/talitos
module, which can be replaced by sg_pcopy_to_buffer().

Akinobu Mita (3):
  lib/scatterlist: introduce sg_pcopy_from_buffer() and
    sg_pcopy_to_buffer()
  crypto: talitos: use sg_pcopy_to_buffer()
  scsi_debug: fix do_device_access() with wrap around range
