fix compilation with gcc 4.2
gcc-4.2 is a lot more picky about its symbol handling. EXPORT_SYMBOL no longer works on symbols that are undefined or defined with static scope. For example, with CONFIG_PROFILE off, I see: kernel/profile.c:206: error: __ksymtab_profile_event_unregister causes a section type conflict kernel/profile.c:205: error: __ksymtab_profile_event_register causes a section type conflict This patch moves the EXPORTs inside the #ifdef CONFIG_PROFILE, so we only try to export symbols that are defined. Also, in kernel/kprobes.c there's an EXPORT_SYMBOL_GPL() for jprobes_return, which if CONFIG_JPROBES is undefined is a static inline and gives the same error. And in drivers/acpi/resources/rsxface.c, there's an ACPI_EXPORT_SYMBOPL() for a static symbol. If it's static, it's not accessible from outside the compilation unit, so should bot be exported. These three changes allow building a zx1_defconfig kernel with gcc 4.2 on IA64.
