v3:
* Using strcasest() correctly.
* Picking Huacai's Acked tag, I seem to have lost it in the last version.

v2:
* Switch to strcasestr().
* Use "test -f" instead of "[-f FILE]".

v1:
* LoongArch and riscv don't have tools/arch/xxxxx/include/uapi/asm/mman.h,
  let's modify the detection rules.
* Allow to use cpuinfo on loongarch.

Yanteng Si (3):
  perf/tools: Allow to use cpuinfo on LoongArch
  perf/trace: Fix mmap_flags for archs use generic mman.h
  perf/trace: Use "test -f" instead of "[-f FILE]"

Define these macros so that the CPU name can be displayed
when running perf report and perf timechart.

It will be simpler without that extra subshell, so
let's use "test -f".

Sorry for duplicated reply (I replied to v2 minutes ago), but I cannot
understand this sentence.  [ ... ] has nothing to do with subshell, it's
just a syntax variant of "test".

Sorry, I mean is that "[" is part of the shell builtin test (and a 
synonym for it),

  not a link to the external command /usr/bin/test.

Using the "test" is simpler because it avoids a lot of "[]".


I'm going to write that in v4, agree?
