Revision 63eb322d89c8505af9b4a3d703e85e42281ebaa0 authored by Ard Biesheuvel on 14 November 2018, 17:55:44 UTC, committed by Ingo Molnar on 15 November 2018, 09:04:47 UTC
Currently, efi_mem_reserve_persistent() may not be called from atomic context, since both the kmalloc() call and the memremap() call may sleep. The kmalloc() call is easy enough to fix, but the memremap() call needs to be moved into an init hook since we cannot control the memory allocation behavior of memremap() at the call site.
