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.
