Restore GFP_DMA flag when allocating memory for CHSC control blocks - Align the numbering scheme for higher-level topology structures like socket, book, drawer with other hardware identifiers e.g. in sysfs, procfs and tools like lscpu ---------------------------------------------------------------- Alexandra Winter (1): s390/topology: Use zero-based numbering for containing entities Peter Oberparleiter (1): s390/cio: Restore GFP_DMA for CHSC allocation Thomas Richter (2): s390/pai: Disable duplicate read of kernel PAI counter value s390/pai: Fix missing PAI counter increments under heavy load arch/s390/kernel/perf_pai.c | 31 +++++++++++++++++++++---------- arch/s390/kernel/topology.c | 10 +++++++--- drivers/s390/cio/chsc.c | 4 ++-- drivers/s390/cio/chsc_sch.c | 20 ++++++++++---------- drivers/s390/cio/scm.c | 2 +- 5 files changed, 41 insertions(+), 26 deletions(-)
