  "message": "s390: support command lines longer than 896 bytes\n\nCurrently s390 supports a fixed maximum command line length of 896\nbytes. This isn\u0027t enough as some installers are trying to pass all\nconfiguration data via kernel command line, and even with zfcp alone\nit is easy to generate really long command lines. Therefore extend\nthe command line to 4 kbytes.\n\nIn the parm area where the command line is stored there is no indication\nof the maximum allowed length, so a new field which contains the maximum\nlength is added.\n\nThe parm area has always been initialized to zero, so with old kernels\nthis field would read zero. This is important because tools like zipl\ncould read this field. If it contains a number larger than zero zipl\nknows the maximum length that can be stored in the parm area, otherwise\nit must assume that it is booting a legacy kernel and only 896 bytes are\navailable.\n\nThe removing of trailing whitespace in head.S is also removed because\ncode to do this is already present in setup_boot_command_line().\n\nSigned-off-by: Sven Schnelle \u003csvens@linux.ibm.com\u003e\nReviewed-by: Heiko Carstens \u003chca@linux.ibm.com\u003e\nSigned-off-by: Vasily Gorbik \u003cgor@linux.ibm.com\u003e\n",
