After the first timekeeping series from Deepa (merged into -tip now)
and my follow-up for IPC system calls, this is a third set of system
call conversions following the same principle.
Most of the changes are straightforward, so I'm grouping them into a
larger series even though the system calls are mostly unrelated to one
another. After this series, the remaining calls that need to be changed
are getrusage()/waitid(), pselect6/ppoll(), timer{,fd}_{get,set}time()
and getitimer()/setitimer(). Those will be sent separately, once they
are matured enough.
To put the changes into perspective, a list of all system calls that
require changes is available in a spreadsheet[1] and I have made
another experimental patch that changes over x86[2] and arm[3] to
actually use them.
Please review!
