If vunmap() is used to unmap a large (e.g., 50 GB) region, it may take
sufficiently long that it triggers soft lockup warnings.
Add a cond_resched() into vunmap_pmd_range() so the calling task may
be resheduled after unmapping each PMD entry. This is how
zap_pmd_range() fixes the same problem
If vunmap() is used to unmap a large (e.g., 50 GB) region, it may take
sufficiently long that it triggers soft lockup warnings.
Add a cond_resched() into vunmap_pmd_range() so the calling task may
be resheduled after unmapping each PMD entry. This is how
