2011-07-24[S390] fix s390 assembler code alignmentsJan Glauber
The alignment is missing for various global symbols in s390 assembly code. With a recent gcc and an instruction like stgrl this can lead to a specification exception if the instruction uses such a mis-aligned address. Specify the alignment explicitely and while add it define __ALIGN for s390 and use the ENTRY define to save some lines of code.

2009-03-18[S390] ftrace/mcount: fix kernel stack backchainHeiko Carstens
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>
2008-12-25[S390] ftrace: function tracer backend for s390Heiko Carstens
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>
