The quilt patch titled Subject: sh: mm: set VM_IOREMAP flag to the vmalloc area has been removed from the -mm tree. Its filename was sh-mm-set-vm_ioremap-flag-to-the-vmalloc-area.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Baoquan He <bhe@xxxxxxxxxx> Subject: sh: mm: set VM_IOREMAP flag to the vmalloc area Date: Mon, 6 Feb 2023 16:40:20 +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.
