usb_unlink_urb() is asynchronous, therefore an URB's buffer may not

This fixes a bug which can cause corruption of the floating-point state
on return from a signal handler.  If we have a signal handler that has
used the floating-point registers, and it happens to context-switch to
another task while copying the interrupted floating-point state from the
user stack into the thread struct (e.g. because of a page fault, or
because it gets preempted), the context switch code will think that the
FP registers contain valid FP state that needs to be copied into the
thread_struct, and will thus overwrite the values that the signal return
code has put into the thread_struct.

This can occur because we clear the MSR bits that indicate the presence
of valid FP state after copying the state into the thread_struct.  To fix
this we just move the clearing of the MSR bits to before the copy.  A
similar potential problem also occurs with the Altivec state, and this
fixes that in the same way.

Consider the prototype for gettimeofday():
	int gettimofday(struct timeval *tv, struct timezone *tz);

Although it is valid to call with /either/ tv or tz being NULL, and
the C version of sys_gettimeofday() supports this, the current version
of gettimeofday() in the VDSO will SEGV if called with a NULL tv.

This adds a check for tv being NULL so that it doesn't SEGV.

Register %ebx serves as the "global offset table base register" for
position-independent code.  For absolute code, %ebx serves as a local
register and has no specified role in the function calling sequence.  In
either case, a function must preserve the register value for the caller.

acpi_copy_wakeup_routine overrides %ebx without saving it, this may corrupt
the called data.

Kevin found that most time the value of Sx is saved in %esi, however
sometimes compiler also uses %ebx.  When this happens, suspends fails since
sleep value in ebx is changed by acpi_copy_wakeup_routine.

The same funtion in X86_64 doesn't have this problem.

Background:
  When a userspace application wants to know about machine check events, it
  opens /dev/mcelog and does a read(). Usually, we found that this interface
  works well, but in some cases, when the system was taking large numbers of
  machine check exceptions, the read() would hang. The system would output a
  soft-lockup warning, and the daemon reading from /dev/mcelog would suck up
  as much of a single CPU as it could spinning in system space.

Description:
  This patch fixes this bug. In particular, there was a "continue" inside a
  timeout loop that presumably was intended to break out of the outer loop,
  but instead caused the inner loop to continue. This patch also makes the
  condition for the break-out a little more evident by changing a
  !time_before to a time_after_eq.

Result:
  The read() no longer hangs in this test case.

Testing:
  On my system, I could replicate the bug with the following command:
    # for i in `seq 15000`; do ./inject_sbe.sh; done
  where inject_sbe.sh contains commands to inject a single-bit error into the
  next memory write transaction.

Patch:
  This patch is against git f1518a08.
