[GIT PULL] target: pending bugfixes + cleanups for v3.2-rc5

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi Linus,

This series contains outstanding bugfixes+cleanups from target-pending
that have been testing in lio-core.git on v3.1 the last number of weeks,
and are ready to be pulled for v3.2 rc-fixes.

This includes the following changes:

- conversion of PYX_TRANSPORT_* sense payload handling to use explict
  se_cmd->scsi_sense_reason assignment to fix a number of cases where
  incorrect sense qualifier was being returned.
- bugfix for fileio and ramdisk backend to properly walk chained SGLs
  when using pre-allocated scsi_cmnd memory with loopback LUNs.
  (Sebastian)
- bugfixes for target CDB parsing with Solaris FC clients (Roland)
- removal of unused target code (Christoph + Joern)
- drop set_user_nice() usage with processing thread context (Bart)
- make unsupported backend configfs attributes return zero (Andy)

The series is based on -rc4, and available here:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git 3.2-rc-fixes

An extra thanks to Sebastian for catching the backend SGL chain bug,
and to everyone else who contributed to this series.

Thanks!
