PATCH 1/1 xtensa: add missing system calls to the syscall table

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

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.

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,

greg k-h
