The original meaning of the old test (p->state > TASK_STOPPED) was
"not dead", since it was before TASK_TRACED existed and before the
state/exit_state split.  It was a wrong correction in commit
14bf01bb to make this test for
TASK_TRACED instead.  It should have been changed when TASK_TRACED
was introducted and again when exit_state was introduced.

Scrap the local __INLINE__ macro, and rename timeval_cmp to fasttime_cmp.

Inline macro was completely unnecessary since the macro was defined
locally to be inline.
timeval_cmp was inaccurately named since it does comparison on
struct fasttimer_t and not on struct timeval.

New (updated) version of ethernet driver for cris v10.

- First steps to simplify and make the MII code more similar
  between the etrax100 and etraxfs ports.

- Start the transmit queue before enabling tx interrupts
  to avoid race with the first frame.

- Flip the comparition statement to stick to physical addresses
  to avoid phys_to_virt mapping a potential null pointer.
  This was not an error but the change simplifies debugging
  of address-space mappings.

- Made myPrevRxDesc local to e100_rx since it was only used there.
  Fixed out of memory handling in e100_rx.  If dev_alloc_skb() fails
  persistently the system is hosed anyway but at least it won't
  loop in an interrupt handler.

- Correct some code formatting issues.

- Add defines SET_ETH_ENABLE_LEDS, SET_ETH_DISABLE_LEDS
  and SET_ETH_AUTONEG used in new cris v10 ethernet driver.

Fix regression introduced with d435d862
("cpu hotplug: mce: fix cpu hotplug error handling").

A CPU which was not brought up during boot (using maxcpus and
additional_cpus parameters) couldn't be onlined anymore.  For such a CPU it
seemed that MCE was not supported during CPU_UP_PREPARE-time which caused
mce_cpu_callback to return NOTIFY_BAD to notifier_call_chain.  To fix this
we:

 - call mce_create_device for CPU_ONLINE event (instead of CPU_UP_PREPARE),
 - avoid mce_remove_device() for the CPU that is not correctly initialized
   by mce_create_device() failure,
 - make mce_cpu_callback always return NOTIFY_OK for CPU_ONLINE event.
   Because CPU_ONLINE callback return value is always ignored.
