From 443d4beb823d4dccaaf964b59df9dd38b4d6aae7 Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Thu, 12 Dec 2013 17:38:50 +0100 Subject: s390/cpum_sf: Add helper to read TOD from trailer entries The trailer entry contains a timestamp of the time when the sample-data-block became full. The timestamp specifies a TOD (time-of-day) value in either the STCK or STCKE format. Provide a helper function to return the TOD value depending on the setting of time format indicator.
