[S390] kernel: Storing machine flags early in lowcore
Currently, the machine_flags are stored late in the startup initialization which results in failing machine type checks (e.g. for MACHINE_IS_VM). To allow these checks, store the machine flags in the lowcore when the machine type has been detected. Moving the machine_flags to the lowcore has been introduced with git commit 25097bf153391f7be4c591d47061b3dc4990dac2 Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
