[ Upstream commit 7e442be7015af524d2b5fb84f0ff04a44501542b ]
Commit 54f9aa1092457 ("tools/perf/powerpc/util: Add support to handle compatible mode PVR for perf json events") introduced to select proper JSON events in case of compat mode using auxiliary vector. But this caused a compilation error in ppc64 Big Endian.
arch/powerpc/util/header.c: In function 'is_compat_mode': arch/powerpc/util/header.c:20:21: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 20 | if (!strcmp((char *)platform, (char *)base_platform)) | ^ arch/powerpc/util/header.c:20:39: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 20 | if (!strcmp((char *)platform, (char *)base_platform)) |
Commit saved the getauxval(AT_BASE_PLATFORM) and getauxval(AT_PLATFORM) return values in u64 which causes the compilation error.
Patch fixes this issue by changing u64 to "unsigned long".
