SubjectRe: [PATCH 1/6] syscalls: use uaccess_kernel in addr_limit_user_check
To try to reproduce your report I built a mps2_defconfig kernel
and then run the qemu command line manually extraced from your
script below, using a mainline qemu built for arm-softmmu, but it
crashes with the following message even for the baseline kernel.

qemu: fatal: Lockup: can't escalate 3 to HardFault (current priority -1)

R00=00000000 R01=00000000 R02=00000000 R03=00000000
R04=00000000 R05=00000000 R06=00000000 R07=00000000
R08=00000000 R09=00000000 R10=00000000 R11=00000000
R12=00000000 R13=ffffffe0 R14=fffffff9 R15=00000000
XPSR=40000003 -Z-- A handler
FPSCR: 00000000

Does anyone have an idea what this means?
