  "message": "x86: fix spontaneous reboot with allyesconfig bzImage\n\nrecently the 64-bit allyesconfig bzImage kernel started spontaneously\nrebooting during early bootup.\n\nafter a few fun hours spent with early init debugging, it turns out\nthat we\u0027ve got this rather annoying limit on the size of the kernel\nimage:\n\n      #define KERNEL_TEXT_SIZE  (40*1024*1024)\n\nwhich limit my vmlinux just happened to pass:\n\n       text           data       bss        dec       hex   filename\n   29703744        4222751   8646224   42572719   2899baf   vmlinux\n\n40 MB is 42572719 bytes, so my vmlinux was just 1.5% above this limit :-/\n\nSo it happily crashed right in head_64.S, which - as we all know - is\nthe most debuggable code in the whole architecture ;-)\n\nSo increase the limit to allow an up to 128MB kernel image to be mapped.\n(should anyone be that crazy or lazy)\n\nWe have a full 4K of pagetable (level2_kernel_pgt) allocated for these\nmappings already, so there\u0027s no RAM overhead and the limit was rather\npointless and arbitrary.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
