#     profiling: attempt to remove per-cpu profile flip buffer
#     
#     This is the really old legacy kernel profiling code, which has long
#     since been obviated by "real profiling" (ie 'prof' and company), and
#     mainly remains as a source of syzbot reports.
#     
#     There are anecdotal reports that people still use it for boot-time
#     profiling, but it's unlikely that such use would care about the old NUMA
#     optimizations in this code from 2004 (commit ad02973d42: "profile: 512x
#     Altix timer interrupt livelock fix" in the BK import archive at [1])
#     
#     So in order to head off future syzbot reports, let's try to simplify
#     this code and get rid of the per-cpu profile buffers that are quite a
#     large portion of the complexity footprint of this thing (including CPU
#     hotplug callbacks etc).
#     
#     It's unlikely anybody will actually notice, or possibly, as Thomas put
#     it: "Only people who indulge in nostalgia will notice :)".
#     
#     That said, if it turns out that this code is actually actively used by
#     somebody, we can always revert this removal.  Thus the "attempt" in the
#     summary line.
#     
#     [ Note: in a small nod to "the profiling code can cause NUMA problems",
#       this also removes the "increment the last entry in the profiling array
#       on any unknown hits" logic. That would account any program counter in
#       a module to that single counter location, and might exacerbate any
#       NUMA cacheline bouncing issues ]
