Hello,

> What's the status of this patch?
I pinged Thomas about it already via irc, but I didn't get a response up
to now. It would be great to get that into 3.12. To make it easy for
Thomas, here is a pull request that includes the fix and converts
at91rm9200 back to clockevents_config_and_register dropping one of the
workarounds for the fixed bug.

The following changes since commit 4a10c2ac2f368583138b774ca41fac4207911983:

  Linux 3.12-rc2 (2013-09-23 15:41:09 -0700)

  ARM: at91: rm9200: switch back to clockevents_config_and_register (2013-10-08 16:58:22 +0200)

----------------------------------------------------------------
The first patch in this pull request fixes an old integer rounding bug in the
timer core that was (and still is) worked around in a few arch's timer code.
The second patch drops such a work around now that the core is fixed.

It would be nice to get that fix into 3.12, but Thomas stopped
responding nearly a month ago---his last mail in this thread[1] dates back
to September 20.

Can one of you please take it directly?

Thanks
Uwe

I second Uwe in his request (aka +1).
