SubjectRe: [PATCH v3 1/2] timer: make deferrable cpu unbound timers really not bound to a cpu
Hi Prasad,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/timers/core]
[also build test ERROR on tip/auto-latest tip/timers/nohz v5.7-rc4 next-20200501]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

base: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 4479730e9263befbb9ce9563a09563db2acb8f7c
config: riscv-nommu_virt_defconfig (attached as .config)
compiler: riscv64-linux-gcc (GCC) 9.3.0

wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
