Porting checkpoint system to arm

Porting checkpoint system to arm

[Jerf gefera]

hi all,
I am porting checkpoint system to arm, it seems(because restarting is not
fine, i only can say it seems) that the checkpointing is fine, but when i
restart the process from image file, then error occurs.
The error is located in _cr_kread function in file sys.c, the return of
vfs_read() is 0. I do not know what is wrong, i hope you can point it out
for me.
Thank you very much!
best wishes,
fera

Can you send us:
	1. the checkpoint file
	2. the relevant dmesg() output for the checkpoint and restart?
	3. perhaps try restart with the -vd options and send us that
	   output?
	4. if possible, a git url to your kernel code?

thanks,
