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% .

Hi  Will,

I have a question about this patch .

If the user space is thumb mode,
The PC should be rewind by 2 bytes,
So the fix_up code should be

Sub lr, lr, #2 .


Am I right ?

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?
