Subject: [PATCH 1/1] mm: vmalloc: Fix a warning in the crash_save_vmcoreinfo_init()
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".
Fixes: 9bdb180b2d ("mm/vmalloc: remove vmap_area_list")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202401120218.y469Puyf-lkp@intel.com/
