and is now a prerequisite for the new preemptible kmap_local() API
which aims to replace kmap_atomic().

- Improvements for the frequency invariant calculations

- Enhanced robustness for the global CPU priority tracking and decision
making

sched/cpupri: Add CPUPRI_HIGHER

Add CPUPRI_HIGHER above the RT99 priority to denote the CPU is in use

XXX: we should probably drive PUSH-PULL from cpupri, that would
automagically result in an RT-PUSH when DL sets cpupri to CPUPRI_HIGHER.

sched/cpupri: Remove pri_to_cpu[1]

pri_to_cpu[1] isn't used since cpupri_set(..., newpri) is
never called with newpri = 99.

The valid RT priorities RT1..RT99 (p->rt_priority = [1..99]) map into
cpupri (idx of pri_to_cpu[]) = [2..100]

Current mapping:

p->rt_priority p->prio newpri cpupri

-1 -1 (CPUPRI_INVALID)

100 0 (CPUPRI_NORMAL)

1 98 98 2
...
49 50 50 50
50 49 49 51
...
99 0 0 100

So cpupri = 1 isn't used.

Reduce the size of pri_to_cpu[] by 1 and adapt the cpupri
implementation accordingly. This will save a useless for loop with an
atomic_read in cpupri_find_fitness() calling __cpupri_find().

New mapping:

p->rt_priority p->prio newpri cpupri

-1 -1 (CPUPRI_INVALID)

100 0 (CPUPRI_NORMAL)

sched/cpupri: Remove pri_to_cpu[CPUPRI_IDLE]

pri_to_cpu[CPUPRI_IDLE=0] isn't used since cpupri_set(..., newpri) is
never called with newpri = MAX_PRIO (140).

Current mapping:

p->rt_priority p->p

sched/cpupri: Remove pri_to_cpu[CPUPRI_IDLE]

pri_to_cpu[CPUPRI_IDLE=0] isn't used since cpupri_set(..., newpri) is
never called with newpri = MAX_PRIO (140).

Current mapping:

p->rt_priority p->prio newpri cpupri

-1 -1 (CPUPRI_INVALID)

140 0 (CPUPRI_IDLE)

1 98 98 3
...
49 50 50 51
50 49 49 52
...
99 0 0 101

Even when cpupri was introduced with commit 6e0534f27819 ("sched: use a
2-d bitmap for searching lowest-pri CPU") in v2.6.27, only

(1) CPUPRI_INVALID (-1),
(2) MAX_RT_PRIO (100),
(3) an RT prio (RT1..RT99)

were used as newprio in cpupri_set(..., newpri) -> convert_prio(newpri).

MAX_RT_PRIO is used only in dec_rt_tasks() -> dec_rt_prio() ->
dec_rt_prio_smp() -> cpupri_set() in case of !rt_rq->rt_nr_running.
I.e. it stands for a non-rt task, including the IDLE task.

Commit 57785df5ac53 ("sched: Fix task priority bug") removed code in
v2.6.33 which did set the priority of the IDLE task to MAX_PRIO.
Although this happened after the introduction of cpupri, it didn't have
an effect on the values used for cpupri_set(..., newpri).

Remove CPUPRI_IDLE and adapt the cpupri implementation accordingly.
This will save a useless for loop with an atomic_read in
cpupri_find_fitness() calling __cpupri_find().

New mapping:

p->rt_priority p->prio newpri cpupri

100 0 (CPUPRI_NORMAL)
