[PATCH AUTOSEL 4.19 38/43] perf unwind: Fix libunwind build failure on i386 systems

[Sasha Levin]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

[ Upstream commit 26acf400d2dcc72c7e713e1f55db47ad92010cc2 ]

Naresh Kamboju reported, that on the i386 build pr_err()
doesn't get defined properly due to header ordering:

  perf-in.o: In function `libunwind__x86_reg_id':
  tools/perf/util/libunwind/../../arch/x86/util/unwind-libunwind.c:109:
  undefined reference to `pr_err'
