The temporary mappings needed to set up the 1:1 mappings must be torn down after use; otherwise they may trigger the WARN_ON() in vmap_pte_range() (namely if the chunk allocated to hold kernel and initial page tables gets close to or exceeds 128Mb, or if a sufficiently high mem= argument causes the static allocations to grow beyond 128Mb, which in either case means these mappings extend into the modules area). Also some minor cleanup. Signed-off-by: Jan Beulich <jbeulich@xxxxxxxxxx> Attachment:
