Subject: arch/arc/kernel/troubleshoot: use vma_lookup() instead of find_vma_intersection()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=88edcaca256a5c13a2dbdcfde435c20bfd376e14;p=users%2Fjedix%2Flinux-maple.git

arch/arc/kernel/troubleshoot: use vma_lookup() instead of find_vma_intersection()

Use the new vma_lookup() call for abstraction & code readability.
