The patch titled
Subject: resource: Use 2-factor allocator calls
has been removed from the -mm tree. Its filename was
resource-add-walk_system_ram_res_rev-fix.patch
This patch was dropped because it was folded into resource-add-walk_system_ram_res_rev.patch
------------------------------------------------------
From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: resource: Use 2-factor allocator calls
As already done treewide, switch from open-coded multiplication to using
2-factor allocation helpers.
