[PATCH v3 00/15] uprobes/x86: fix the handling of relative jmp's/call's

[Oleg Nesterov <oleg@redhat.com>]

Hello.

OK, let me resend everything. This is what I am going to add to my tree
and ask Ingo to pull. I am still testing this all, seems to work so far.

Changes:

	01-09: No changes, added the acks from Masami.

	09-15: Updated the changelogs, the comments in 13/15, plus the
	       following renames:

	       - s/ttt/branch/

	       - s/disp/offs/

	       - s/_clear_displacement/_clear_offset/

	       No changes in compiled code, I preserved the acks from Jim.

>From 13/15:

	Note: as Denys Vlasenko pointed out, amd and intel treat "callw" (0x66 0xe8)
	differently. This patch relies on lib/insn.c and thus implements the intel's
	behaviour: 0x66 is simply ignored. Fortunately nothing sane should ever use
	this insn, so we postpone the fix until we decide what should we do; emulate
	or not, support or not, etc.

Yes. Lets discuss (and fix?) this separately, I'll write another email.

Any objections?

Oleg.
