Subject: [patch]Fix copy-and-paste error in BSD accounting

From: Tim Schmielau <[email protected]>

Fix copy and paste error in jiffies_to_AHZ conversion which leads
to wrong BSD accounting information on alpha and ia64 when
CONFIG_BSD_PROCESS_ACCT_V3 is turned on.

Also update comment to match reorganised header files.
