Philipp Rudo 70e7705b02 kernel/crash_core: suppress unknown crashkernel parameter warning ... [ Upstream commit 71d2bcec2d ] When booting with crashkernel= on the kernel command line a warning similar to Kernel command line: ro console=ttyS0 crashkernel=256M Unknown kernel command line parameters "crashkernel=256M", will be passed to user space. is printed. This comes from crashkernel= being parsed independent from the kernel parameter handling mechanism. So the code in init/main.c doesn't know that crashkernel= is a valid kernel parameter and prints this incorrect warning. Suppress the warning by adding a dummy early_param handler for crashkernel=.
