[PATCH 0/4] uprobes: remove is_swbp_at_addr() fromregister/unregister

[Oleg Nesterov]

Hello.

1. the usage of is_swbp_at_addr() is confusing. This series tries
   to answer the questions we got during the discussion about
   powerpc port which has multiple trap insns.

   Ananth, please review too ;) at least the changelog in 1/4.

   Note: the changelog doesn't mention is_swbp_insn(). If powerpc
   wants to change it, we need 2 helpers for verify_opcode() and
   for is_swbp_at_addr().

2. This is also preparation for the pre-filtering I am working on.

   In particular, this series tries to make clear the fact that
   register/unregister should be "idempotent".

Oleg.
