* [S390] smp: use correct cpu address in print_cpu_info()Heiko Carstens2010-10-25
| | | | | | | | | | | | | | Up to now print_cpu_info() uses the cpu address stored in it's local lowcore to print a message to the console. The cpu address in the lowcore is (in this case) however not the physical cpu address of the local cpu. It's the address of the cpu that issued the sigp restart which started the local cpu. Fix this by using the store cpu address instruction instead. It's not that anybody really cares since this is broken since more than ten years...

* [S390] Add hwcap flag for the etf3 enhancement facilityAndreas Krebbel2009-03-26
| | | | | | | | | | | | | | The Extended Translation Facility 3 (ETF3) added instructions which allow conversions between different unicode character maps (UTF-8, UTF-32 ...). These instructions got enhanced with a later version of the ETF3 allowing malformed multibyte chars to be recognized and reported correctly. The attached patch reserves bit 8 in the elf hwcaps vector for the enhanced version of ETF3. The bit corresponds to the stfle bits 22 and 30 and will only be set if both of the stfle bits are set.
