Subject: sh: mm: set VM_IOREMAP flag to the vmalloc area
Date: Fri, 13 Jan 2023 11:19:21 +0800
Currently, for vmalloc areas with flag VM_IOREMAP set, except of the
specific alignment clamping in __get_vm_area_node(), they will be
1) Shown as ioremap in /proc/vmallocinfo;
2) Ignored by /proc/kcore reading via vread()
So for the ioremap in __sq_remap() of sh, we should set VM_IOREMAP
in flag to make it handled correctly as above.
