Then some other platform will stop to work. https://bugzilla.kernel.org/show_bug.cgi?id=11892 The 26/30 and 27/30 patches are bound together to fix one bug. Some quote from description from the 26th patch: ACPI_EC_STORM_THRESHOLD was initially 20 when it's created, and was changed to 8 in 2.6.28 commit 06cf7d3c7 "ACPI: EC: lower interrupt storm threshold" to fix kernel bug 11892 by forcing the laptop in that bug to work in polling mode. Hope this answers your question.
