Title:
  CAPI: CGZIP Wrong CAPI MMIO timeout (256usec desired but 1usec default
  setting in cxl.ko driver)

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  In Progress
Status in linux source package in Yakkety:
  Fix Released

Bug description:
  ---Problem Description---
  MMIO timeout for CAPI driver is too small for CGZIP application. 1usec default should be replaced by 256usec, which prevents cxl driver output in kernel log.
    
  ---uname output---
  4.2.0-34-generic
   
  ---Additional Hardware Info---
  Nallatech FPGA card with CGZIP bitstream. 

  Machine Type = Tuleta, but also others

  ---Steps to Reproduce---
   Do extensive stress test using CGZIP card.
   
  Patch for this fix has been accepted to ppc-linux git tree viz commit https://git.kernel.org/cgit/linux/kernel/git/powerpc/linux.git/commit/?h=next&id=4aec6ec0da9c72c0fa1a5b0d1133707481347bb3

  Required for gzip capi adapter for 14.04.5.
  So would like the fix in 16.04, so that it can roll "naturally" in 14.04.5
