[PATCH 1/1] mm: vmalloc: Fix a warning in the crash_save_vmcoreinfo_init()

["Uladzislau Rezki (Sony)" <urezki@gmail.com>]

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".
