f82a9e7b9fa922bb9cccb00aae684a27b79e6df7 | Analyze and fix the following issue in the Linux kernel code: um: fix execve stub execution on old host OSs | Problem Details:
The stub execution uses the somewhat new close_range and execveat
syscalls. Of these two, the execveat call is essential, but the
close_range call is more about stub process hygiene rather than safety
(and its result is ignored).
Replace both calls with a raw syscall as older machines might not have a... | ```diff

The stack needs to be properly aligned so 16 byte memory accesses on the
stack are correct. This was broken when introducing the dynamic math
register sizing as the rounding was not moved appropriately.

The init_task instance of struct task_struct is statically allocated and

with zero.
