Subject: [xen] export cpu_llc_id as gpl
Message-id: 46D3484A.3080909@redhat.com
O-Subject: [PATCH RHEL5.1] EXPORT_SYMBOL_GPL crusade
Bugzilla: 429004

Of those 4, flush_tlb_current_task, flush_tlb_mm and raw_safe_halt
are EXPORT_SYMBOLed in Xen but not exported at all on non-Xen.
However, these three are all called from inline functions in
include files, which makes me a little nervous about removing
them.

The last symbol, cpu_llc_id, is not referenced from any kernel
modules. at all.  That means that one is safe to change.

IMHO this EXPORT_SYMBOL(_GPL) thing is probably not important
enough to risk regressions, so I am trying to play it as safely
as possible from the regression point of view.
