Hi,
This series is an update to the arm64 tagged address ABI documentation
patches v8, posted here:
http://lkml.kernel.org/r/20190815154403.16473-1-catalin.m...
From v8, I dropped patches 2 and 3 as they've been queued by Will via
the arm64 tree. Reposting patch 1 (unmodified) as it should be merged
via the mm tree.
Changes in v9:
- Replaced the emphasized/bold font with a typewriter one for
function/constant names
- Simplified the mmap/brk bullet points when describing the tagged
pointer origin
- Reworded expected syscall behaviour with valid tagged pointers
- Reworded the prctl/ioctl restrictions to clarify the allowed tagged
pointers w.r.t. user data access by the kernel
