| * | [S390] s390: move machine flags to lowcore | Christian Ehrhardt | 2009-04-14 | 1 | -0/+25 |
| Currently the storage of the machine flags is a globally exported unsigned long long variable. By moving the storage location into the lowcore struct we allow assembler code to check machine_flags directly even without needing a register. Addtionally the lowcore and therefore the machine flags too will be in cache most of the time.
