| |
The vmcoreinfo_append_str() function expects "long unsigned int" type as a second argument(0x%lx) to print a beginning of vmalloc start address which is defined as a VMALLOC_START macro.
For some architectures it can be considered as "int" type, for example m68 generates a compile warning message. To fix it cast a second argument to "unsigned long".
