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/[email protected] [ mingo: Capitalize IPI, etc. ] Fixes: 2815a56 ("x86/mm/tlb: Add tracepoint for TLB flush IPI to stale CPU") Signed-off-by: Tal Zussman <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> Reviewed-by: Steven Rostedt (Google) <[email protected]> Reviewed-by: David Hildenbrand <[email protected]> Reviewed-by: Rik van Riel <[email protected]> Link: https://patch.msgid.link/[email protected]
