The patch titled
RTC: Ratelimit "lost interrupts" message
has been removed from the -mm tree. Its filename was
rtc-ratelimit-lost-interrupts-message.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: RTC: Ratelimit "lost interrupts" message
From: Ben Collins <bcollins@xxxxxxxxxx>
We gets lots of these when the kernel is running on a hypervisor. Zach says
"a guest kernel trying to get high frequency RTC will also be inaccurate, and
inevitably will have unhidable interrupt lateness."
