Feng Tang 1d9c47a329 ipmi: use vzalloc instead of kmalloc for user creation ... [ Upstream commit 7c47a219b9 ] We met mulitple times of failure of staring bmc-watchdog, due to the runtime memory allocation failure of order 4. bmc-watchdog: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0-1 CPU: 1 PID: 2571 Comm: bmc-watchdog Not tainted 5.5.0-00045-g7d6bb61d6188c #1 Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.00.01.0015.110720180833 11/07/2018 Call Trace: dump_stack+0x66/0x8b warn_alloc+0xfe/0x160 __alloc_pages_slowpath+0xd3e/0xd80 __alloc_pages_nodemask+0x2f0/0x340 kmalloc_order+0x18/0x70 kmalloc_order_trace+0x1d/0xb0 ipmi_create_user+0x55/0x2c0 [ipmi_msghandler] ipmi_open+0x72/0x110 [ipmi_devintf] chrdev_open+0xcb/0x1e0 do_dentry_open+0x1ce/0x380 path_openat+0x305/0x14f0 do_filp_open+0x9b/0x110 do_sys_open+0x1bd/0x250 do_syscall_64+0x5b/0x1f0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Using vzalloc/vfree for creating ipmi_user heals the problem Thanks to Stephen Rothwell for finding the vmalloc.h inclusion issue.
