* [S390] use inline assembly contraints available with gcc 3.3.3Martin Schwidefsky2010-02-261-16/+6
| | | | | | | | | | | Drop support to compile the kernel with gcc versions older than 3.3.3. This allows us to use the "Q" inline assembly contraint on some more inline assemblies without duplicating a lot of complex code (e.g. __xchg and __cmpxchg). The distinction for older gcc versions can be removed which saves a few lines and simplifies the code.

| * [SCSI] zfcp: Remove duplicated code for debug timestampsChristof Schmitt2009-09-051-0/+8
| | | | | | | | | | | | | | | | | | | | The timestamp calculation used for s390dbf output is the same in a private zfcp function and in debug.c. Replace both with a common inline function.

* | [S390] introduce get_clock_monotonicHeiko Carstens2009-09-111-0/+14
|/ | | | | | | | | | Introduce get_clock_monotonic() function which can be used to get a (fast) timestamp. Resolution is the same as for get_clock(). The only difference is that the timestamps are monotonic and don't jump backward or forward.

* [S390] add read_persistent_clockMartin Schwidefsky2009-04-141-0/+5
| | | | | | | | | Add a read_persistent_clock function that does not just return 0. Since timekeeping_init calls the function before time_init has been called move reset_tod_clock to early.c to make sure that the TOD clock is running when read_persistent_clock is invoked.
