Subject: [PATCH v3 0/6] perf probe, tracing/uprobes: Support probing at absolute address

The goal of these 4 patches is to allow perf probing at absolute address
for uprobes and kprobes. During the development several small problem in
'perf probe -l' is found and fixed.

Patch v2 can be found from [1].

Following Masami's suggestion, v3 splits bugfixs into their own
patches instead of merging with feature.

In this series, patch 1/6 to 4/6 are small bugfix. Patch 5/6 is the main
patch which support the new syntax. Patch 6/6 is a kernel side small bugfix.

Patch 1/6 and 6/6 have already been acked by Masami Hiramatsu.

Wang Nan (6):
  perf probe: Prevent segfault when reading probe point with absolute
    address
  perf probe: Fix list result when symbol can't be found
  perf probe: Fix list result when address is zero
  perf probe: Fix error reported when offset without function
  perf probe: Support probing at absolute address
  tracing/uprobes: Do not print '0x (null)' when offset is 0
