[Kyrill Tkachov]

Now with patch attached.

Also forgot to mention.
Tested arm-none-eabi.

Hi all,

The scheduler algorithms are defined in sched-int.h as:
enum sched_pressure_algorithm
{
    SCHED_PRESSURE_NONE,
    SCHED_PRESSURE_WEIGHTED,
    SCHED_PRESSURE_MODEL
};
We should use the enum name SCHED_PRESSURE_MODEL rather than the direct integer
value (2).

This doesn't make any functional difference, just makes it a bit more readable
(and avoids any unexpected effects in the future if enum
sched_pressure_algorithm is extended).

Committed as obvious with r210471.

Cheers,

      * config/arm/arm.c (arm_option_override): Use the SCHED_PRESSURE_MODEL
      enum name for PARAM_SCHED_PRESSURE_ALGORITHM.
