Hi All,
BUG if we attempt to return to userspace but the to-be-restored PSR value keeps us in privileged mode (defeating an issue that ftracetest found).
Fixing patches are following, apply top down on LTS *v4.14/4.9/4.4* They are tested by lkft and kernelci build/boot, no regression found.
8bafae202c82 ARM: BUG if jumping to usermode address in kernel mode 3aaf33bebda8 ARM: avoid faulting on qemu
Thanks for these, now queued up.
