[PATCH 0/1] drm/xe/oa: Zero OA buffer at allocation

[Bommu Krishnaiah <krishnaiah.bommu@intel.com>]

Zero the OA buffer immediately after allocation because kernel BO pages
are not guaranteed to be initialized. This prevents stale data exposure
through mmap and fixes the xe_oa tail-address-wrap test.
