That's wrong, so replace that reference for the correct ones.

There was debate on the list and we decided that it would be more consistent with the rest of i2c if we defaulted to 100 kHz. ...but we never updated the bindings. Let's fix this. NOTE: since the i2c driver itself hasn't actually landed yet and the SoC here is very new it seems terribly unlikely that anyone was relying on the old 400 kHz number, so I'll assume this is an OK "incompatible" device tree change.

They also caused a huge performance regression, because "->poll()" was no longer a trivial file operation that just called down to the underlying file operations, but instead did at least two indirect calls. Indirect calls are sadly slow now with the Spectre mitigation, but the performance problem could at least be largely mitigated by changing the "->get_poll_head()" operation to just have a per-file-descriptor pointer to the poll head instead. That gets rid of one of the new indirections. But that doesn't fix the new complexity that is completely unwarranted for the regular case. The (undocumented) reason for the poll() changes was some alleged AIO poll race fixing, but we don't make the common case slower and more complex for some uncommon special case, so this all really needs way more explanations and most likely a fundamental redesign.

( In followup patches we'll remove the remaining calls in low level arch handlers as well and remove the callback altogether. ) Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Acked-by: Thomas Gleixner <tglx@linutronix.de> Cc: Ananth N Mavinakayanahalli <ananth@linux.vnet.ibm.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: linux-arch@vger.kernel.org Link: https://lore.kernel.org/lkml/152942462686.15209.6324404940493598980.stgit@devbox Signed-off-by: Ingo Molnar <mingo@kernel.org>
