The broken patch went into 2.4.18-pre1 >with a curt changelog: > >- S390 merge (IBM) The patch that was merged in 2.4.18-pre* has been created against 2.4.17-pre7 and it did work. The problem is that not all of the changes I sent Marcelo have been accepted. One of the patches was the asm-offsets fix that removes all of the hardcoded offsets from entry.S. Another patch was accepted that changed the thread structure and this created the inconsistency. >Patch attached. Well your patch halfway fixes one of the problems. Halfway because not the fp_regs structure has changed its size but the pt_regs pointer has been removed from the thread structure. Incidentally I sent an s390 update to Marcelo yesterday and the minimal fixes including an rwsem.h implementation and the partition detection fixes are about 2000 lines.
