[PATCH] kselftest: mm: remove exclusion of building soft-dirty test in arm64

[Yeoreum Yun]

Since commit 0389c305ef56 (“selftests/mm: skip soft-dirty tests when CONFIG_MEM_SOFT_DIRTY is disabled”),
the soft-dirty test is skipped when soft-dirty is not supported.

There is therefore no reason to exclude the test from being built on
arm64. Remove the arm64-specific exclusion.

Does that mean we can also the following?

Ah right. since all archs have the soft-dirty, we can remove the if
condition.

Thanks!
