arch/tile: bug fix: exec'ed task thought it was still single-stepping
To handle single-step, tile mmap's a page of memory in the process space for each thread and uses it to construct a version of the instruction that we want to single step. If the process exec's, though, we lose that mapping, and the kernel needs to be aware that it will need to recreate it if the exec'ed process than tries to single-step as well. Also correct some int32_t to s32 for better kernel style. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
