Handle very old kernel (<4.11) userfaultfd scenario Prior to 4.11, kernel didn't report any userfaultfd features via API ioctl. The basic modes (COPY/ZEROPAGE/WAKE) were supported only on private anonymous mappings. In this CL removed the check for shared mappings as it is not required in copy-mode. Bug: 262209538 Test: Golem (art-opt intel targets) Change-Id: I79539f9f2d63b4709f63623f2fc748e8a3fb1d3b
