Hello Dave, Thanks for reviewing. I've reflected your comments and this is the second version. About sample vmcores, I'll send email to you in private. Please wait for a while. Change Log v0 => v1) * Move REMOTE_DAEMON bit from pc->flags to pc->flags2; See PATCH 01. SADUMP bit is now introduced in pc->flags. * Fix the bug, I found locally, that in per_cpu_ptr(), symbol value of symbol __per_cpu_offset was directly used. Here should have dereferenced the symbol value.
