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.
