x86/mm/tlb/trace: Export the TLB_REMOTE_WRONG_CPU enum in <trace/events/tlb.h>
When the TLB_REMOTE_WRONG_CPU enum was introduced for the tlb_flush tracepoint, the enum was not exported to user-space. Add it to the appropriate macro definition to enable parsing by userspace tools, as per: Link: https://lore.kernel.org/all/20150403013802.220157513@goodmis.org [ mingo: Capitalize IPI, etc. ] Fixes: 2815a56 ("x86/mm/tlb: Add tracepoint for TLB flush IPI to stale CPU") Signed-off-by: Tal Zussman <tz2294@columbia.edu> Signed-off-by: Ingo Molnar <mingo@kernel.org> Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Reviewed-by: David Hildenbrand <david@redhat.com> Reviewed-by: Rik van Riel <riel@surriel.com> Link: https://patch.msgid.link/20251212-tlb-trace-fix-v2-1-d322e0ad9b69@columbia.edu
