[PATCH 0/2] lib/sort: Clean up sort_nonatomic() and sort_r_nonatomic()

[Kuan-Wei Chiu]

Remove the sort_nonatomic() and sort_r_nonatomic() APIs from the kernel
library.

Currently, the arm-smmu-v3 driver is the sole in-tree user of 
sort_nonatomic(). Because the array size being sorted is small in
practice, there is no real risk of triggering a soft lockup. Therefore,
the periodic cond_resched() calls provided by the _nonatomic variant
are unnecessary.

With the only in-tree user updated, the _nonatomic APIs are no longer
needed anywhere in the kernel. Removing them effectively drops the
wrapper function and eliminates the may_schedule branch from the
innermost loop of the core sorting logic, slightly simplifying the code.
