Subject: mm: page_alloc: pass PFN to __free_pages_bootmem -fix
Stephen Rothwell reported the following
Today's linux-next build (sparc defconfig) failed like this:
mm/bootmem.c: In function 'free_all_bootmem_core':
mm/bootmem.c:237:32: error: 'cur' undeclared (first use in this function)
__free_pages_bootmem(page++, cur++, 0);
^
Caused by commit "mm: page_alloc: pass PFN to __free_pages_bootmem".
He also merged a fix. The only difference in this version is one line is
moved so the final diff context is clearer. This is a fix to the mmotm
patch mm-page_alloc-pass-pfn-to-__free_pages_bootmem.patch
