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
(5.x
or 5.x-rcY). The series file is in broken-out.tar.gz and is
duplicated in
https://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.
I am seeing build errors on i386 or x86_64 when CONFIG_EPOLL is not set:
../kernel/user.c: In function ‘free_user’:

Also do this change in kernel/user.c please:
if (percpu_counter_init(&root_user.epoll_watches, 0, GFP_KERNEL))
- panic("percpu cpunter alloc failed");
+ panic("percpu counter alloc failed");
