Huang Ying f10d77cded x86, fakenuma: Fix invalid starting node ID ... [ Upstream commit ccae0f36d5 ] Commit: cc9aec03e5 ("x86/numa_emulation: Introduce uniform split capability") uses "-1" as the starting node ID, which causes the strange kernel log as follows, when "numa=fake=32G" is added to the kernel command line: Faking node -1 at [mem 0x0000000000000000-0x0000000893ffffff] (35136MB) Faking node 0 at [mem 0x0000001840000000-0x000000203fffffff] (32768MB) Faking node 1 at [mem 0x0000000894000000-0x000000183fffffff] (64192MB) Faking node 2 at [mem 0x0000002040000000-0x000000283fffffff] (32768MB) Faking node 3 at [mem 0x0000002840000000-0x000000303fffffff] (32768MB) And finally the kernel crashes: BUG: Bad page state in process swapper pfn:00011 page:(____ptrval____) refcount:0 mapcount:1 mapping:(____ptrval____) index:0x55cd7e44b270 pfn:0x11 failed to read mapping contents, not a valid kernel address? flags: 0x5(locked|uptodate) raw: 0000000000000005 000055cd7e44af30 000055cd7e44af50 0000000100000006 raw: 000055cd7e44b270 000055cd7e44b290 0000000000000000 000055cd7e44b510 page dumped because: page still charged to cgroup page->mem_cgroup:000055cd7e44b510 Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 5.9.0-rc2 #1 Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019 Call Trace: dump_stack+0x57/0x80 bad_page.cold+0x63/0x94 __free_pages_ok+0x33f/0x360 memblock_free_all+0x127/0x195 mem_init+0x23/0x1f5 start_kernel+0x219/0x4f5 secondary_startup_64+0xb6/0xc0 Fix this bug via using 0 as the starting node ID.
