powerpc/kernel: Initialize load_tm on task creation
Currently tsk->thread.load_tm is not initialized in the task creation and can contain garbage on a new task. This is an undesired behaviour, since it affects the timing to enable and disable the transactional memory laziness (disabling and enabling the MSR TM bit, which affects TM reclaim and recheckpoint in the scheduling process). Fixes: 5d176f75 ("powerpc: tm: Enable transactional memory (TM) lazily for userspace") Cc: stable@vger.kernel.org # v4.9+ Signed-off-by: NBreno Leitao <leitao@debian.org> Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>
