a small series of preempt_disable/enable -> migrate_disable/enable pushdown proposals
In mainline a number of preempt_disable/enable are actually topology control and not actual concurrency control - these cases can be pushed down to a preemptible migrate_disable/enable.
This little series contains a few pushdowns from preempt_disable to migrate_disable where code pattern scans using cocci scripts suggested this to be possible. The cases detected were then reviewed and tested with the migrate_disable/enable respectively with the preempt_disable/enable completely removed in one case.
Testing was done but is of very limited use for locking/migration related issues, so a review of the code analysis/rational is requested along with additional testing.
thx! hofrat
