* [S390] improve mcount codeMartin Schwidefsky2009-09-111-137/+10
| | | | | | | Move the 64 bit mount code from mcount.S into mcount64.S and avoid code duplication. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] ftrace: add function graph tracer supportHeiko Carstens2009-06-121-0/+79
| | | | | | | Function graph tracer support for s390. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] ftrace: add function trace mcount test supportHeiko Carstens2009-06-121-12/+26
| | | | | | | | Add support for early test if the function tracer is enabled or disabled. Saves some extra function calls. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] ftrace: add dynamic ftrace supportHeiko Carstens2009-06-121-27/+92
| | | | | | | Dynamic ftrace support for s390. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] ftrace/mcount: fix kernel stack backchainHeiko Carstens2009-03-181-2/+4
| | | | | | | | With packed stack the backchain is at a different location. Just use __SF_BACKCHAIN as an offset to store the backchain. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* [S390] ftrace: function tracer backend for s390Heiko Carstens2008-12-251-0/+56
This implements just the basic function tracer (_mcount) backend for s390. The dynamic variant will come later. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
