README for mm-of-the-moment:

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (4.x
or 4.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

um (or uml) defconfig on i386 and/or x86_64:

../mm/page_alloc.c: In function 'memmap_init_zone':
../mm/page_alloc.c:5450:5: error: implicit declaration of function 'memblock_next_valid_pfn' [-Werror=implicit-function-declaration]
     pfn = memblock_next_valid_pfn(pfn, end_pfn) - 1;
     ^
