Registered by Leann Ogasawara on 2013-10-31

This is a general Ubuntu kernel catch all session. We'll discuss things such as:

* 14.04 kernel version target
* 14.04 delta review
* raid4-5 what to do about it
* 14.04 kernel testing (eg. 14.04 HWE stack in Precise)
* 14.04 kernel config requests
* Bug #1247784: CONFIG_RT2800USB_RT3573 = m/y
* Bug #1248270: CONFIG_EXT[23]=n
* CONFIG_OABI_COMPAT = n (should no longer be needed)
* Necessary to hold a kernel session every vUDS?

[colin-king] Refer to LP:743688. Benchmark TRANSPARENT_HUGEPAGE_ALWAYS vs CONFIG_TRANSPARENT_HUGEPAGE_MADVISE. Currently we have CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y, but request is to turn that off and use TRANSPARENT_HUGEPAGE_ALWAYS=y instead. Again, we want evidence this is a reasonable decision: DONE
