Comment 12 for bug 1326097

Alejandro Virrueta, the mainline kernel is not supported as per https://wiki.ubuntu.com/Kernel/MainlineBuilds#Does_the_kernel_team_support_the_mainline_kernel_builds.3F .

Despite this, if it continues to work without problems, if you would like a backport to Trusty, the next step would be to fully reverse commit bisect the kernel in order to identify the fix commit following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F . Just finding adjacent kernel versions is not fully commit commit bisecting.
