040b00acec crypto/nx: Remove 'pid' in vas_tx_win_attr struct 
When window is opened, pid reference is taken for user space
windows. Not needed for kernel windows. So remove 'pid' in
vas_tx_win_attr struct.

now, but this patch enables GZIP for user space usage.

4aebf3ce26 crypto/nx: Make enable code generic to add new GZIP compression type 
Make setup and enable code generic to support new GZIP compression type.
Changed nx842 reference to nx and moved some code to new functions.

instead of 0 for per_cpu send window in nx_delete_coprocs().
