From: Eliav Farber <farbere@amazon.com> stable inclusion from stable-v5.10.143 commit 8e8dc8fc53a8bc428a009438ff0608cf0ac079d1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0U6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit bb9195bd6664d94d71647631593e09f705ff5edd ] This issue is relevant when "intel,vm-map" is set in device-tree, and defines a lower number of VMs than actually supported. This change is needed for all places that use pvt->v_num or vm_num later on in the code.
