- Subject: [Committed] S/390: Add hwcaps value for transactional execution
Hi,
I've committed the following patch in order to add the new hwcaps
value for the transactional execution facility.
Bye,
-Andreas-
2012-11-08 Andreas Krebbel <Andreas.Krebbel@de.ibm.com>
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add "te".
* sysdeps/s390/dl-procinfo.h (HWCAP_S390_TE): Add enum value.
* sysdeps/unix/sysv/linux/s390/hwcap.h (HWCAP_S390_TE): Add macro
definition.
