Michael Ellerman 68fc378ce3 Revert "powerpc/tm: Abort syscalls in active transactions" ... This reverts commit feba40362b. Although the principle of this change is good, the implementation has a few issues. Firstly we can sometimes fail to abort a syscall because r12 may have been clobbered by C code if we went down the virtual CPU accounting path, or if syscall tracing was enabled. Secondly we have decided that it is safer to abort the syscall even earlier in the syscall entry path, so that we avoid the syscall tracing path when we are transactional. So that we have time to thoroughly test those changes we have decided to revert this for this merge window and will merge the fixed version in the next window. NB. Rather than reverting the selftest we just drop tm-syscall from TEST_PROGS so that it's not run by default.
