kbuild: Fix genksyms handling of DEFINE_PER_CPU(struct foo_s *, bar);
This is a one-line change to parse.y. To take advantage of this the scripts/genksyms/*_shipped files needs to be rebuild - this is the next patch. When a .c file contains: DEFINE_PER_CPU(struct foo_s *, bar); the .cpp output looks like: __attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar; With the existing parse.y, the value inside the paranthesis of __typeof__() does not evaluate as a type_specifier and therefore per_cpu__bar does not get assigned a type for genksyms which results in the EXPORT_PER_CPU_SYMBOL() not generating a CRC value. I have compared the Modules.symvers with and without this patch and for ia64's defconfig, the only change is: Before 0x00000000 per_cpu____sn_nodepda vmlinux After 0x9d3f3faa per_cpu____sn_nodepda vmlinux per_cpu____sn_nodepda was the original source of my problems.
