    Subject[PATCH 3.10 01/16] Revert "powerpc/tm: Always reclaim in start_thread() for exec() class syscalls"
    Date
    This reverts commit 8110080dc53335d5dd99b123144a6174f19ffc65.

    Guenter noticed that this breaks PPC build when CONFIG_PPC_TRANSACTIONAL_MEM
    is set, because this patch was not for 3.10.
