[PATCH v3 2/5] linux-user: Fix madvise(MADV_DONTNEED) on alpha |
Date: |
Tue, 6 Sep 2022 02:08:36 +0200 |
MADV_DONTNEED has a different value on alpha, compared to all the other
architectures. Fix by using TARGET_MADV_DONTNEED instead of
MADV_DONTNEED.
Fixes: 892a4f6a750a ("linux-user: Add partial support for MADV_DONTNEED")
