From: Alexandre Ghiti <alex@xxxxxxxx>

[ Upstream commit 61fc1ee8be26bc192d691932b0a67eabee45d12f ]

Increase COMMAND_LINE_SIZE as the current default value is too low
for syzbot kernel command line.

There has been considerable discussion on this patch that has led to a
larger patch set removing COMMAND_LINE_SIZE from the uapi headers on all
ports.  That's not quite done yet, but it's gotten far enough we're
confident this is not a uABI change so this is safe.
