zipl/boot: Always clear COMMAND_LINE_EXTRA region #122

Closed huth closed 2 years ago

Always clear the COMMAND_LINE_EXTRA region, also in case sclp_setup() fails. If the region is not cleared properly, there might be junk in there after a reboot, causing confusion for the kernel later.

All right, I've updated the branch to use COMMAND_LINE_EXTRA_SIZE instead. Thanks for your review!
