Hi Will,
Could I know what's your git branch is mainly used for ?
https://git.kernel.org/cgit/linux/kernel/git/will/linux.git
I mean if the branch is used for ARM arch maintenance ? If yes, I think I can send future bugs about ARM to you directly, And do not need ping-pang in the mail list .
Thanks for your help .

Hi Will
Oh I see, Thanks for your reply
Yes , we are testing for it , But need some time to wait for the result , Because The stability test need some time to reproduce this issue , And this issue doesn't reproduce 100% .

No, because we don't have OABI-compat support for Thumb applications and force everything down the EABI path instead.
Did you manage to test the patch?
