  "message": "x86: Use find_e820() instead of hard coded trampoline address\n\nJens found the following crash/regression:\n\n[    0.000000] found SMP MP-table at [ffff8800000fdd80] fdd80\n[    0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 0-fff BIOS data page\n\nand\n\n[    0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 6000-7fff TRAMPOLINE\n\nand bisected it to b24c2a9 (\"x86: Move find_smp_config()\nearlier and avoid bootmem usage\").\n\nIt turns out the BIOS is using the first 64k for mptable,\nwithout reserving it.\n\nSo try to find good range for the real-mode trampoline instead of\nhard coding it, in case some bios tries to use that range for sth.\n\nReported-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nTested-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nLKML-Reference: \u003c4B21630A.6000308@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
