[PATCH 0/7] uprobes/x86: introduce uprobe_xol_ops and arch_uprobe->ops

[Oleg Nesterov]

Hello.

x86 can not handle the rip-relative jmp/call instrsuctions, the probed
task can be killed by general protection fault. I'll describe this in
more details when I send the fixes. Now I am sending the preparations
which (I hope) make sense anyway, please review.

My main concern is 3/7. I know absolutely nothing about instruction
decoding, so I can only guess what, for example, OPCODE1() == 0xff or
MODRM_REG() == 2 actually means. Please review.

Ananth, David, please ack/nack the first change, it affects powerpc/arm.

Oleg.
