linux-toradex.git/arch/s390/kernel/mcount.S, branch v3.4.78 Linux kernel for Apalis and Colibri modules [S390] fix s390 assembler code alignments 2011-07-24T08:48:21+00:00 Jan Glauber jang@linux.vnet.ibm.com 2011-07-24T08:48:19+00:00 144d634a21caff1d54cb4bb0d073774e88130045 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.

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.
