Since version 2.1 the return value of a system call might be

negative even if the call succeeded. E.g., the `lseek' system call
|
|
might return a large offset. Therefore we must not anymore test
|

for < 0, but test for a real error by making sure the value in R0

is a real error number. Linus said he will make sure the no syscall

returns a value in -1 .. -4095 as a valid result so we can savely

test with -4095. */
