Hi Greg,
Could you please include this patch in the next stable tree? It adds
system calls required for libc builds, so would be great to have it there.
Thanks,
-Chris

Subject: [PATCH 1/1] xtensa: add missing system calls to the syscall table
Add the following system calls to the syscall table:
fallocate
sendmmsg
umount2
syncfs
epoll_create1
inotify_init1
signalfd4
dup3
pipe2
timerfd_create
timerfd_settime
timerfd_gettime
eventfd2
preadv
pwritev
fanotify_init
fanotify_mark
process_vm_readv
process_vm_writev
name_to_handle_at
open_by_handle_at
sync_file_range
perf_event_open
rt_tgsigqueueinfo
clock_adjtime
prlimit64
kcmp
Note that we have to use the 'sys_sync_file_range2' version, so that
the 64-bit arguments are aligned correctly to the argument registers

What stable releases do you want it in?
Also, please look at Documentation/stable_kernel_rules.txt for how to do
this properly (hint, emailing me isn't the best way...)
thanks,
