code.

And more importantly a fix to the kernel_thread() asm code to correctly

Is this something that should be done in <asm-generic/dma-mapping.h>?

Otherwise the compiler can delete them (this is one of those "how on earth
did it ever work before" moments).

The posix-timers implementation associates timers with the creating thread
and destroys timers when their creator thread dies.  POSIX clearly
specifies that these timers are per-process, and a timer should not be torn
down when the thread that created it exits.  I hope there won't be any
controversy on what the correct semantics are here, since POSIX is clear
and the Linux feature is called "posix-timers".

The attached program built with NPTL -lrt -lpthread demonstrates the bug.
The program is correct by POSIX, but fails on Linux.  Note that a until
just the other day, NPTL had a trivial bug that always disabled its use of
kernel timer syscalls (check strace for lack of timer_create/SYS_259).  So
unless you have built your own NPTL libs very recently, you probably won't
see the kernel calls actually used by this program.

Also attached is my patch to fix this.  It (you guessed it) moves the
posix_timers field from task_struct to signal_struct.  Access is now
governed by the siglock instead of the task lock.  exit_itimers is called
from __exit_signal, i.e.  only on the death of the last thread in the
group, rather than from do_exit for every thread.  Timers' it_process
fields store the group leader's pointer, which won't die.  For the case of
SIGEV_THREAD_ID, I hold a ref on the task_struct for it_process to stay
robust in case the target thread dies; the ref is released and the dangling
pointer cleared when the timer fires and the target thread is dead.  (This
should only come up in a buggy user program, so noone cares exactly how the
kernel handles that case.  But I think what I did is robust and sensical.)

A problem exists where a 32-bit application can have a huge bss, one that
is so large that an overflow of the TASK_SIZE happens.  But in this case,
the overflow is not detected in load_elf_binary().  Instead, because
arithmetic is being done using 32-bit containers, a truncation occurs and
the program gets loaded when it shouldn't have been.  Subsequent execution
yields unpredictable results.

The attached patch fixes this problem by checking for the overflow
condition and sending a SIGKILL to the application if the overflow is
detected.  This problem can in theory exist when loading the elf
interpreter as well, so a similar check was added there.
