sys/arm/arm trap.c
Log:
Ok I am an idiot. On 32 bits big-endian systems, it is needed to handle the
syscalls using __syscall but only actually returning 32bits, such as mmap(),
specially : they set the return value in td->td_retval[0], but the userland
functions will expect this in r1, and not in r0 as it is normally done, as it
is the LSB. So add a special case for all these syscalls (all except lseek,
which truly returns 64bits).
Many thanks to Peter Grehan for his patience while explaining me the issue.
