Hi Amit, FYI, kernel build failed on tree: git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux.git release head: c072fed95c9855a920c114d7fa3351f0f54ea06e commit: 023614183768a7ac62898bded5ec6c0c9fecbdd9 [18/25] thermal: add generic cpufreq cooling implementation config: i386-randconfig-m064 (attached as .config) Note: the thermal/release HEAD c072fed builds fine. It only hurts bisectibility.
