Placing thread_info in the kernel stack leaves it vulnerable to stack overflow attacks. This short series addresses that by using the existing THREAD_INFO_IN_TASK infrastructure.
As this is my first patch in this part of the kernel, I'm looking for feedback about the general approach as well as specific comments on places where I've missed something.
I've only run this on armhf running under qemu, so while I've tried to make patches for other code paths, I haven't been able to test those.
(yes, I know checkpatch.pl complains about whitespace in asm-offsets.c, I decided to leave the existing whitespace alone)
