Hi all,
After merging the xen tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
arch/x86/xen/setup.c: In function 'xen_add_extra_mem':
arch/x86/xen/setup.c:65: error: implicit declaration of function 'reserve_early'
Caused by commit 42ee1471e9b879479a15debac752314a596c738e ("xen:
implement "extra" memory to reserve space for pages not present at boot")
interacting with commit a9ce6bc15100023b411f8117e53a016d61889800 ("x86,
memblock: Replace e820_/_early string with memblock_"). This latter
commit was in the xen tree yesterday (via a merge of tip/core/memblock)
but has been removed today (but it is in Linus' tree).
Linus will need this fixup patch when he merges the xen tree. I have
applied it to linux-next today and can carry it as necessary.
