e4e8947c8d ibmvstgt: Generate clean patches, even if the input contains #ifdefs on LINUX_VERSION_CODE.

1af1e674d4 Patch from Dorit Halsadi <Dorit.Halsadi@dothill.com> and Uri Yanai <Uri.Yanai@ngsoft.com> adding NPIV support to the SCST Target driver for Qlogic 24xx/25xx Fibre Channel cards 
with minor fixes.

Note: you need NPIV-supporting firmware as well as NPIV-supporting switches to use NPIV.

26f9165b48 Made sure that sparse can process scst.h. Apparently there is a bug in sparse which makes sparse interpret single quotes in preprocessor statements as character delimiters.

cef1b4cdff The changes included in the patch below are: 
- If someone tries to build SCST on an RHEL 5 system without having
run 'make enable_proc' first, complain.
- Do not define set_cpus_allowed_ptr() on RHEL 5 since RHEL 5 does
have a declaration for this function.
  The function itself is not exported from the kernel however (this is probably a bug). Because of that, replace
the call to set_cpus_allowed_ptr() in scst_main.c by a call to set_cpus_allowed().
- Do not define the variable 'err' on kernels where that variable is
not used in order to avoid a compiler warning.
- Also in scst_vdisk.c, pass a 16-bit value as the first argument of
put_unaligned() when writing to a 16-bit variable in order to avoid a compiler warning.

Signed-off-by: Bart Van Assche <bvanassche@acm.org>

with fixes and additions:

 - In scst_vdisk.c we need 32-bit values, not 16, fixed
 - Optimal UNMAP granuality changed to 1.

5c955fad01 Changes: 
- Removed a superfluous state transition in srpt_abort_scst_cmd() and
  cleaned up the source code of this function a bit.
- Implemented a workaround for the InfiniBand kernel stack bug that could
  result in IB_WC_RECV error completions to be delivered with an incorrect
  wr_id.
- RDMA read error completions and SRP_CRED_REQ send error completions are now
  processed correctly.
- If posting an SRP_RSP fails, don't set the delivery status because sending
  the response will be retried anyway.
