3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: libin <huawei.libin@xxxxxxxxxx> commit c84da8b9ad3761eef43811181c7e896e9834b26b upstream. In nop_mcount, shdr->sh_offset and welp->r_offset should handle endianness properly, otherwise it will trigger Segmentation fault if the recordmcount main and file.o have different endianness.
