[PATCH 0/2] sched: Removed unused mc_capable() and smt_capable()

[Bjorn Helgaas]

This is just cleanup of a couple unused interfaces and (for sparc64) a
supporting variable.

[PATCH 1/2] sched: Remove unused mc_capable() and smt_capable()

[Bjorn Helgaas]

Remove mc_capable() and smt_capable().  Neither is used.

Both were added by 5c45bf279d37 ("sched: mc/smt power savings sched
policy").  Uses of both were removed by 8e7fbcbc22c1 ("sched: Remove stale
power aware scheduling remnants and dysfunctional knobs").

[PATCH 2/2] sparc64: Remove unused sparc64_multi_core

[Bjorn Helgaas]

Remove sparc64_multi_core because it's not used any more.

It was added by a2f9f6bbb30e ("Fix {mc,smt}_capable()"), and the last uses
were removed by e637d96bf462 ("sched: Remove unused mc_capable() and
smt_capable()").

sched: Remove unused mc_capable() and smt_capable()

Remove mc_capable() and smt_capable().  Neither is used.

Both were added by 5c45bf279d37 ("sched: mc/smt power savings sched
policy").  Uses of both were removed by 8e7fbcbc22c1 ("sched: Remove stale
power aware scheduling remnants and dysfunctional knobs").

sparc64, sched: Remove unused sparc64_multi_core

Remove sparc64_multi_core because it's not used any more.

It was added by a2f9f6bbb30e ("Fix {mc,smt}_capable()"), and the last uses
were removed by e637d96bf462 ("sched: Remove unused mc_capable() and
smt_capable()").
