In the file ports/sysdeps/unix/sysv/linux/hppa/bits/atomic.h a LWS call is 
done, and then the kernel return value is negated (from - to +) with this 
line:
 sub   %%r0, %%r21, %%r21  
A small optimization is to drop this negation and instead change
 if(lws_errno == EFAULT || lws_errno == ENOSYS)
to 
 if(lws_errno == -EFAULT || lws_errno == -ENOSYS)
