From: Ard Biesheuvel <ardb@kernel.org> mainline inclusion from mainline-5.11-rc1 commit 0869f3b9da38889faef2ccafcf675c713d4a3aa8 category: feature issue: #I3ZXZF CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ------------------------------------------------- We always pass the same value for 'type' so pull it into the __pv_stub macro itself.
