Attempting to build the perf tool on arm or arm64 targets results in the following failure:arch/arm/util/unwind-libunwind.c: In function ‘libunwind__arch_reg_id’: arch/arm/util/unwind-libunwind.c:43:3: error: implicit declaration of function ‘pr_err’ [-Werror=implicit-function-declaration] pr_err("unwind: invalid reg id %d\n", regnum); ^ This is due to commit 84f5d36f4866 ("perf tools: Move pr_* debug macros into debug object") moving the pr_* macros into a new header file, but failing to update architectures other than x86. This patch adds the missing includes, and fixes the build again.
For ARM64, we also need the patch[1] "perf tools: Fix arm64 build error" which is already queued in linux-next.
