Jan Beulich ae5758a1a7 procfs: also fix proc_reg_get_unmapped_area() for !MMU case ... Commit fad1a86e25 ("procfs: call default get_unmapped_area on MMU-present architectures"), as its title says, took care of only the MMU case, leaving the !MMU side still in the regressed state (returning -EIO in all cases where pde->proc_fops->get_unmapped_area is NULL). From the fad1a86e25 changelog: "Commit c4fe244857 ("sparc: fix PCI device proc file mmap(2)") added proc_reg_get_unmapped_area in proc_reg_file_ops and proc_reg_file_ops_no_compat, by which now mmap always returns EIO if get_unmapped_area method is not defined for the target procfs file, which causes regression of mmap on /proc/vmcore. To address this issue, like get_unmapped_area(), call default current->mm->get_unmapped_area on MMU-present architectures if pde->proc_fops->get_unmapped_area, i.e. the one in actual file operation in the procfs file, is not defined" Signed-off-by: Jan Beulich <jbeulich@suse.com> Cc: HATAYAMA Daisuke <d.hatayama@jp.fujitsu.com> Cc: Alexey Dobriyan <adobriyan@gmail.com> Cc: David S.
