Subject: [PATCH V2 0/3] perf tools: Fix for cases where cpumode is incorrect or insufficient

Hi

Here is V2:
These patches probably deal with most cases except the one fixed by David
Miller's "perf callchain: Honour the ordering of
PERF_CONTEXT_{USER,KERNEL,etc}" patch, and also cat_backtrace() which looks
like it has the same problem, and the cs-etm fix.


Changes in V2:
      perf tools: Add fallback functions for cases where cpumode is insufficient
	Rename fallback functions to both end in _fb
	Add and use  variable  machine->single_address_space

      perf tools: Use fallback for sample_addr_correlates_sym() cases
      perf tools: Use fallbacks for branch stacks
	Adjusted for the re-naming above

      perf intel-pt: Insert callchain context into synthesized callchains
      perf intel-pt/bts: Calculate cpumode for synthesized samples
	Dropped because they have been applied
