| |
Hi Andrew,
[As reported by Randy for uml ...]
After merging the akpm-current tree, today's linux-next build (sparc defconfig) failed like this:
/home/sfr/next/next/mm/page_alloc.c: In function 'memmap_init_zone': /home/sfr/next/next/mm/page_alloc.c:5450:11: error: implicit declaration of function 'memblock_next_valid_pfn'; did you mean 'memblock_virt_alloc_low'? [-Werror=implicit-function-declaration] pfn = memblock_next_valid_pfn(pfn, end_pfn) - 1; ^~~~~~~~~~~~~~~~~~~~~~~ memblock_virt_alloc_low
Caused by commit
c3d8f8809701 ("mm: page_alloc: skip over regions of invalid pfns on UMA")
I have applied the following patch for today:
