[patch 5/9] s390: increase cio_trace debug event size.

[Martin Schwidefsky <schwidefsky@de.ibm.com>]

From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>

[patch 5/9] s390: increase cio_trace debug event size.

Debugging events in cio_trace/hex_ascii are truncated for some trace
entries. Increase trace event size to 16 bytes to cover longer text
events, make CIO_HEX_EVENT an inline function that loops to cover bigger
hex events.
