Merge patch series "memtest performance improvements"
Rasmus Villemoes <[email protected]> says:
The first two patches make memtest run ~40x faster (when, as it should
be, dcache is disabled), with the second patch being responsible for
most of that. At least on the beagleboneblack which I used for
testing; other boards and configurations will likely see different
numbers.
This is for CONFIG_SYS_ALT_MEMTEST=y and
CONFIG_SYS_ALT_MEMTEST_BITFLIP=n; one could probably get a similar
improvement in the bitflip case since that also has a schedule() call
in the inner loop.
