David Ahern b69fb7699c sparc64: perf: Add sanity checking on addresses in user stack ... Processes are getting killed (sigbus or segv) while walking userspace callchains when using perf. In some instances I have seen ufp = 0x7ff which does not seem like a proper stack address. This patch adds a function to run validity checks against the address before attempting the copy_from_user. The checks are copied from the x86 version as a start point with the addition of a 4-byte alignment check. Signed-off-by: David Ahern <david.ahern@oracle.com> Signed-off-by: David S.
