[PATCH v2 net-next 0/8] net/ncsi: NCSI Improvment and bug fixes

[Gavin Shan <gwshan@linux.vnet.ibm.com>]

This series of patches improves NCSI stack according to the comments
I received after the NCSI code was merged to 4.8.rc1:

  * PATCH[1/8] fixes the build warning caused by xchg() with ia64-linux-gcc.
    The atomic operations are removed. The NCSI's lock should be taken when
    reading or updating its state and chained state.
  * Channel ID (0x1f) is the reserved one and it cannot be valid channel ID.
    So we needn't try to probe channel whose ID is 0x1f. PATCH[2/8] and
    PATCH[3/8] are addressing this issue.
  * The request IDs are assigned in round-robin fashion, but it's broken.
    PATCH[4/8] make it work.
  * PATCH[5/8] and PATCH[6/8] reworks the channel monitoring to improve the
    code readability and its robustness.
  * PATCH[7/8] and PATCH[8/8] introduces ncsi_stop_dev() so that the network
    device can be closed and opened afterwards. No error will be seen.

Changelog
=========
v2:
  * The NCSI's lock is taken when reading or updating its state as the
    {READ,WRITE}_ONCE() isn't reliable.
